Why would a small-scale natural farm in Nova Scotia select to cease tilling the soil (or go no-till)?
This apply, known as No-Until, isn’t an apparent one for a farm similar to ours.
Actually, there’s fairly a bit of luggage across the time period “no-till” – it’s mostly used to explain bigger scale field-crop farms that use herbicides to kill any crops that attempt to develop (moreover ones which might be herbicide resistant like Spherical-Up Prepared corn or soybeans), as a substitute for tillage that may in any other case additionally work to kill or strongly disturb so-called “weeds” (that are merely outlined as any plant rising the place a human being doesn’t need it).
No-till, in that context, is much from natural, although it’s used as a manner to assist protect the topsoil. Tillage can have many destructive results, particularly when carried out too typically or on the unsuitable time. Certainly one of these impacts is erosion of topsoil – which may occur from wind or water.
Nonetheless, herbicides should not good for the life within the soil. Not one of the “-cides” (that means “killer”) actually solely have one impact. An herbicide doesn’t solely kill herbs. It impacts life usually. The natural farming philosophy is all about life – within the soil, above the soil – and inspiring and selling life (which incorporates, by the way in which, honouring and respect for the function of dying as a part of the renewal of life – very a lot showcased in using compost).
So, our imaginative and prescient is considered one of marrying the 2 – of Natural + No-Until.
Our practices gained’t be precisely the identical as anybody else equally training Natural No-Until. Farming doesn’t work greatest as a prescriptive set of practices.
They’re distinctive to our scale (small), our time and skills (it’s simply the two of us farming right here) and our location and local weather (short-season). Right here, we are able to count on in any given yr both severe drought or extreme rain (or each). This has been considered one of our motivating elements – as a threat administration technique. Untilled soil is extra resilient to both of those extremes.
This publish is the story (to date) of our tillage journey with this land that we’re blessed to farm upon. The story has not completed. We aren’t on the “fortunately ever after” section that comes after the neat and tidy “The Finish” of a narrative.
The story is de facto extra of a studying journey for us, with a number of continued (and persevering with) exploration and experimentation. (As a result of, as so superbly expressed by Masanobu Fukuoka, “The last word aim of farming isn’t the rising of crops, however the cultivation and perfection of human beings.”)
With that mentioned, and with an abundance of humility for all that we have no idea, we’re sharing our story UP TO THIS POINT IN TIME of studying to reduce to the purpose of not tilling (aka “no-till”). Or actually simply studying extra in regards to the soil beneath our toes and the way the life inside in and above it reacts to our altering administration practices.
Whereas our prospects and folk on the whole could discover curiosity within the the rest of this publish, a few of its detailed descriptions are more likely to be most attention-grabbing and/or helpful to fellow farmers who’re additionally on this journey.
Within the Starting
Once we first moved to this farm on the finish of 2011, it had been lower for hay (or extra precisely, haylage) for over 10 years. The provincial soil map described the soil as being excessively well-draining to the purpose of droughtiness and having a low pH (estimating pH to be beneath 5). Once we have been on the lookout for land, we all the time introduced a shovel with us and dug into the soil. We deliberately determined upon this spot’s deep sandy loam as a result of we knew it was a texture we might work with primarily based on our expertise engaged on different farms. However, as our soil isn’t clay-rich (subsoil included), we wanted to be additional cautious with water and fertility administration AND work to extend the soil’s natural matter. Amazingly, after doing soil assessments, the pH was truly slightly below 6 (and after we requested our neighbour who had been chopping the hay – he mentioned that 10 years prior, they’d unfold lime, although none since).
Since neither of us have had off-farm jobs since beginning our farm enterprise, and have all the time wanted to make 100% of our livelihood from the farm, we began from the start rising veggies and flowers on a part of the farm whereas cowl cropping different elements to arrange them for future years (if we had off-farm jobs, it might have been greatest to simply cowl crop all the pieces that first yr – prepping the fields for crops the next yr).
One a part of our farm was ploughed (by a neighbor) after which disc harrowed, however in one other part we simply tilled beds into the sector and left the grassy pathways (this was in a piece with out sofa grass….there was a discipline with a pure stand of sofa grass that we cowl cropped for 4 years earlier than ever planting a vegetable or flower into).
We hoped the grassy pathways could be a house for and assist the beds to re-colonize the fungi and micro organism and different soil organisms (like earthworms or beetles) that have been being impacted by the rototiller. Plus we cherished that we might simply stroll on the pathways regardless of the climate and never find yourself with muddy boots or harvest bins. We mowed the paths with a push mower.
Soil Well being
The well being of the soil is akin to the well being of a checking account. It’s a long-term funding that pays again yearly and is additional necessary in an emergency (like drought or heavy downpours). The philosophy of Natural farming is ALL ABOUT soil well being (regardless of the prevalent concept that it’s all in regards to the lack of pesticide use).
Soil well being = plant well being = animal (together with human) well being. And an increasing number of, the popularity that Soil Well being = Planetary Local weather Well being as properly.
Soil is not only a substance that holds crops upright. There’s a entire world of species dwelling within the soil that people barely know something about and are nonetheless simply scratching the floor of information about. It’s mainly like exploring the Galaxy – there’s a lot to find.
Tilling can actually be accomplished with kind of intention and may trigger kind of injury to the soil. However, it doesn’t matter what, some injury might be accomplished to somebody (some species or relationship between species). Fungi (the underground strands of mushroom life that may span miles) are particularly delicate to tillage.
Even earlier than we began exploring the concept of implementing no-till practices on our farm, we have now been obsessed and in love with the concept of contributing positively to soil well being.
Mulching Towards Weeds
Within the fields that had been ploughed after which disc-ed, so many grasses began re-growing that we wouldn’t have been in a position to make a dwelling until we used some form of weed barrier. So, we used bio-degradable plastic mulch within the beds that we transplanted seedlings into (for probably the most half, we did additionally direct seed into some beds and harvested across the grasses arising). We left the pathways to develop grasses and mowed them too for probably the most half, although we did try and weed them with a wheel hoe early on. Primarily all weeding on this space was a problem as there have been piles of sod and bunches of tangled sofa grass roots turned over all over the place.
That biodegradable plastic mulch actually saved our bacon at first although we not use it and haven’t for years. The story of the explanation why that’s might be discovered on this weblog publish.
As a result of we not have been utilizing this mulch, we wanted to search for different administration choices: each for weeding (we didn’t need to spend extra time weeding) and for soil well being (we didn’t need to be cultivating ceaselessly or stale seed bedding all through the season and actually didn’t need to find yourself with a dry soil crust on high or erosion). You may learn extra about how we have been trying into varied choices on this weblog publish.
We began trialing various things: curler crimping (utilizing our rototiller, disengaged, with the PTO turned off, permitting the tines to roll freely over the crop with the burden of the machine pushing down), mowing, panorama cloth, tarping, compost mulch.
Curler Crimping Trials
We trialed 3 strategies for transplanted fall brassicas (kohlrabi and romanesco cauliflower) with beds that have been:
a) curler crimped rye used as a mulch,
b) flail mowed rye used as a mulch,
c) rototilled soil, naked.
The time it took to transplant into each the curler crimped and the flail mowed beds was for much longer and required a trowel (it was additionally difficult so as to add amendments) in comparison with the convenience of the rototilled mattress. The yields (measurement of head and bulb on this case) have been additionally smaller within the 2 different beds in comparison with the rototilled beds, although the flail mowed mattress was higher than the curler crimped mattress and we did find yourself with extra perennial weeds within the curler crimped mattress in comparison with the flail mowed mattress.
In our local weather, by the point an overwintered cowl crop of rye reaches its pollen-shed stage (the best stage for curler crimping), there are fewer crops we’re nonetheless transplanting (apart from sooner maturing crops like lettuce and inexperienced onions), particularly ones that may profit from the cooler soil temperatures within the undisturbed cowl cropped soil.
We’re at the moment not doing any curler crimping, preferring to flail mow in situations the place curler crimping might work, although we could do some once more sooner or later – almost definitely earlier than sowing extra cowl crop seed into the rolled mulch.
A number of current assets that relate to this that I need to share:
The background data of our story wouldn’t be full with out mentioning our ardour for canopy crops. We actually get pleasure from rising cowl crops (and inexperienced manure crops) as a software for rising our soil’s well being in place. Seeing a fantastic, numerous, sturdy stand of canopy crops brings us a lot pleasure, and is, for us, the best manner so as to add carbon and nitrogen to the soil.
Early on, our rotation was easy – usually 1 yr cowl crop – 1 yr annual crops (veg and flowers), forwards and backwards. The exception was the plots that we have been nonetheless making ready so as to add to our future rotation – which have been in multi-year, steady cowl cropping (typically to cope with sofa grass and a few areas of compaction).
We began to really feel that this rotation was too constricting for us. That we weren’t in a position to totally profit from cowl crops inside this one yr of canopy crop. That the timing of planting was too delicate. And that establishing and terminating the quilt crops typically resulted in additional tillage, negating a number of the soil-building results we hoped cowl cropping would carry to our soils.
So, we determined we wanted to create a rotation primarily based on our private wants and needs and administration capability.
Our New Crop Rotation
The crop rotation that we created at this level (4 years in the past now) actually was the increase we wanted to assist us determine tips on how to carry all the pieces collectively. That is the rotation we’re nonetheless working with.
It’s a 6 yr rotation. 3 years in cowl crop, then 3 years in annual greens/flowers.
We’ve got some fields which might be exterior this rotation which might be slowly being planted to perennials. Our tunnels are additionally exterior this rotation.
Years 1, 2, & 3 of our Crop Rotation
The three years of canopy crops doesn’t have its personal particular cowl crop rotation – we’re nonetheless all the time experimenting with totally different crops and with multi-species cowl crops (aka cowl crop cocktails), although the threerd (final) yr of canopy crops will get planted to a winter-killed cowl crop in the summertime. We want to create a extra predictable cowl crop rotation for these years. We at the moment broadcast our cowl crop seed, or use a Jang or Earthway push seeder for smaller areas, although we’re keen on a no-till drill seeder to assist us plant our cowl crop seed extra successfully.
Yr 4 (1st yr of veggies)
1st yr of veggies – aka the Cucurbit Yr. We put down any amendments on the floor of the winterkilled cowl crop residue and a skinny sprinkling of compost.
We cowl the entire plot in panorama cloth (which we pin down with floor staples). This discipline is planted to cucurbits (planted into holes within the panorama cloth) together with Zucchini, Cucumbers, Melons, and Winter Squash.
- The panorama cloth prevents weeds from arising and protects the highest of the soil in order that organisms dwelling within the soil can break down that residue on the floor of the soil from the winterkilled cowl crops.
- As a result of we don’t use any pesticides (together with natural authorised ones) on the farm, having a long-rotation (6 years) between cucurbits has been useful, as pests like cucumber beetles and squash bugs can overwinter within the soil. We additionally use row covers early within the crops life (earlier than flowering) to supply a bodily barrier for flying cucumber beetles rising from final yr’s cucurbit discipline on the lookout for meals.
- Cucurbits additionally develop fairly fortunately in soil with breaking-down residue (as these of you with compost piles rising squash have seemingly observed).
- Cucurbits additionally profit from the added warmth from the black panorama cloth (particularly necessary in our quick seasons).
- We get the advantages of tarping by way of making ready a discipline, however we’re nonetheless rising a crop with dwelling roots and many photosynthesizing leaves, serving to to seize and retailer carbon within the soil and feeding soil organisms.
One factor that we’ve been contemplating is habitat for squash bees, native small bees which might be specialised in pollinating squash flowers. These ground-dwelling bees require patches of naked soil close to to the squash crops. These bees are in reality not often seen by people as they pollinate a lot earlier within the day and are lots smaller than honeybees or bumblebees you might typically discover pollinating your squash blossoms. Due to this, it’s exhausting to know the way properly we’re doing on behalf of the squash bees – although we haven’t had points with squash pollination. (Click on right here for more information on squash bees!)
AKA: The direct-seeding yr or fast turnover yr
Early within the season, we pull off the panorama cloth as we’d like it. The sector is now free from residue and weeds. We use this discipline to direct seed into – fast-growing crops like salad combine, arugula, different child greens, carrots, beets, cilantro, dill, salad turnips and spring radishes.
Compost is barely added to beds appear to be they might use a bit extra cowl on this yr.
It’s been superb to see the life within the soil, earthworms, sure, but additionally fungi. Our soil texture and aggregation has improved and it appears tighter (which I do know wouldn’t be an interesting phrase to these with very tight, heavy, clay-rich soils – however our soil was fairly unfastened to start with). We typically add a sprinkling of bentonite clay as we’re amending a mattress and we’ve been very pleased with the outcomes, particularly with our onions.
On the finish of this season, we attempt to fill the sector with as many crops as we are able to to overwinter (although some late carrot beds simply get a mulching of the carrot tops we depart on high). Whereas not each winter is profitable with each overwintered crop (the winters crammed with alternating freeze and thaw are the worst), we nonetheless take the danger and plant: bulb onions, inexperienced onions, asian greens, “cool flowers”, child kale, carrots, and naturally garlic and tulips. The key, usually, appears to be to time them so that they’re not too mature when going into the winter however have nonetheless rooted in.
When it comes to garlic we now plant them by pushing them evenly into the highest of the soil, or planting with a trowel and masking with compost mulch. Tulip bulbs are pushed evenly into the soil floor, and coated with a layer of compost mulch.
These overwintered crops are the start of the 6th and closing yr of the rotation (earlier than going again to cowl crops – its extra of a circle fairly than an finish). Yr 6 is the one yr in our rotation the place we make the most of a deep compost mulch (although for us – “deep” is normally not more than 1 inch of compost).
In spring, after beds of most overwintered crops have been harvested, we broadfork if wanted, amend, after which add compost mulch (we don’t re-apply extra compost mulch to the garlic or tulip beds that already received an software the autumn prior).
Fast word on the compost we use:
To be used as a mulch, we use a reasonably excessive carbon/low nitrogen compost made with byproducts from our native forestry and seafood industries, from an organization that has an natural certificates for the completed compost (this is essential for us as we’re licensed natural). We typically buy an organic-approved manure primarily based compost however we use that yet another as an modification to the soil, fairly than as a compost mulch.
Fast word on Phosphorus:
Whereas there are numerous opinions on using deep compost mulch in a no-till or minimal until system, one concern is the addition of extra phosphorus than wanted which may result in run-off and water air pollution. This issues us too, which is without doubt one of the causes we restrict compost mulch to just one out of 6 years in our rotation and why we don’t use the manure-based compost as a deep compost mulch. Phosphorus turns into focused on crops within the seed. Grains are seeds and so, within the Canadian Prairies, many grain (or different seed) farmers are very involved with lack of Phosphorus – as a result of they make their dwelling by the export of Phosphorus by means of the seeds they promote. A lot of the manure that may be had is from livestock farmers who’re feeding grain to their animals (solely grass-fed livestock managers usually hold their manure on their pasture). This implies excessive Phosphorus within the manure. On the opposite aspect of the coin, are farmers utilizing manure or manure-based compost, with out exporting a lot phosphorus. Which might result in build-up of overly excessive ranges. That is why that pleasant old style rotation of grains after which veggies grown with manure held a lot knowledge. As we do develop seeds and grains within the type of cowl crops, we’ve been contemplating how we might stability this nutrient out with our rotation – keep tuned – we haven’t figured it out but.
Fast word on spreading compost:
This was one of many greatest bottlenecks we had on the farm when making an attempt to determine our system. So, we dreamed up the concept of a self-loading compost spreader with our machinist buddy Dan that was designed to completely meet our personal wants. It eliminated compost spreading as a bottleneck and labored delightfully properly for us. You may learn extra about it in our weblog publish.
After the compost mulch is unfold, we dibble completely spaced holes in our mattress (relying on what crop we might be planting) and transplant. This yr will get all transplanted crops (moreover cucurbits) together with flower crops (however not together with crops planted into tunnels). We additionally direct seed trellised peas and dry beans (which we solely began rising final yr).
We’ve got began to transplant utilizing trowels, as a result of we need to be certain that the underside of the seedling plug is touching soil (fairly than simply in compost mulch) as our compost isn’t very wealthy in vitamins and may dry out.
Our plot in Yr 6 finally ends up trying like a patchwork, as we transplant and harvest out and re-plant all through the season.
Whereas the following image is kind of dramatic (it’s taken after frost-irrigating….you’ll be able to learn extra about that on this weblog publish), I’m utilizing it as an example what occurs within the fall.
In Yr 6, the final yr earlier than 3 years of canopy crops, some beds are cropped out early and get a rye or rye/vetch cowl crop. Nonetheless, we’re nonetheless harvesting from this discipline after we’ve had many frosty nights. For crops like flowers, we merely depart the crops within the discipline to function a kind of canopy crop – with their roots remaining within the soil to assist maintain it and the tops standing so long as doable to proceed as habitat or locations for birds to discover. The following yr, any beds that weren’t planted to cowl crop the autumn prior, might be planted to cowl crops within the spring.
A word about pests (aka different species) OR The advantages of inaction (aka commentary or ready)
We observed we have been beginning to have some cutworm issues just a few years in the past, which we hadn’t had earlier than. Our first step all the time with any form of situation is to do a variety of analysis. Not simply how others are “managing” the pest, however fairly in regards to the species lifecycle, its habits, and even its function or advantages within the larger ecosystem (which in fact all the pieces has – no matter whether or not they get pleasure from the identical meals we do).
There have been a number of suggestions that mentioned that tillage was essential to cope with cutworms. Although we additionally know many farmers who until and nonetheless have points with cutworms.
Anyhow, our cutworm situation, whereas actually noticeable and irritating, wasn’t main us to do something greater than search round after we noticed proof of a recent lower (cutworms lower the tops off seedlings), look across the close by soil, and squish the fats juicy perpetrator. We have been positively not doing this every day. We have been just about simply re-planting locations the place cutworms had taken out the earlier seedling. And that technique was understanding properly sufficient.
Effectively, this yr, we began to see some piles of soil pushed up from beneath and deposited on high. The character inflicting these piles of soil was not consuming the roots of any of our crops, although typically their soil pile pushed out a plant with its roots. We appeared into it and located that the piles have been the work of this delightfully distinctive being – the star-nosed mole. Studying in regards to the star-nosed mole crammed us with awe and surprise of this unbelievable world we stay in (learn this), although some folks take into account these piles a nuisance, and due to this fact the star-nosed mole, a pest.
Nonetheless, the star-nosed mole, is an insect eater (not a herbivore) and eats cutworms (in addition to mainly all bugs, together with ones we people take into account “useful” like earthworms). The star-nosed mole additionally mainly takes on the useful facet of tillage – transferring soil from decrease down up and vice versa, and aerating the soil.
We’ve discovered it so attention-grabbing to contemplate how not tilling the soil has given the chance to this different species to make its personal livelihood from this land (there are such a lot of bugs now) – and who has proven us that tillage is completed by different species too.
That livelihood philosophy is de facto necessary to us – our aim is making our personal dwelling from the farm with out impeding many others (of assorted species) to make their livelihoods on the identical time. I’m not very within the concept of claiming: “that is my spot to make my livelihood and you’ll go over there within the woods – that’s ever-increasingly being clear lower for people – and keep there and make your livelihood there, away from me.”
For us, excessive yields embrace the yields for as many species as doable. Land that produces “yields” for under people isn’t very excessive yielding in our opinion and is actually not “feeding the world” since this world is made up of a plethora of species. (learn extra about our concepts round this, in case you like, at our weblog publish right here).

Wrapping it up
Effectively, this publish is kind of lengthy already so I’m going to wrap it up. I haven’t talked about something in regards to the perennials or the tunnel crops, however that may be for a future publish.
I’ll depart you with just a few extra assets to take a look at:
- No-till growers podcast (in addition to no-till flowers podcast)….we’ve even been on this podcast
- No-till farmer (regardless that it’s geared in the direction of a bigger scale, and never essentially even natural, sort of farm, there may be nonetheless a number of good data and we are able to all study from one another
