Cultivating Questions A Bio-Extensive Demonstration

Cultivating Questions: A Bio-Extensive Demonstration

Two management directives led us to a bio-extensive design. First, because our staff is small, we required a system that would provide inherently good weed control. Bermuda grass was a particular concern. Our second directive demanded a reduced dependence on outside fertility inputs, particularly industrial poultry litter. Many, if not most, of the organic market farms in our region depend on broiler or layer litter for annual supplies of nitrogen and organic matter. We wanted an alternative that would be more independent and sustainable.

Cultivating Questions A Diversity of Cropping Systems

Cultivating Questions: A Diversity of Cropping Systems

As a matter of convenience, we plant all of our field vegetables in widely spaced single rows so we can cultivate the crops with one setup on the riding cultivator. Row cropping makes sense for us because we are more limited by labor than land and we don’t use irrigation for the field vegetables. As for the economics of planting produce in work horse friendly single rows, revenue is comparable to many multiple row tractor systems.

Cultivating Questions A Horsedrawn Guidance System

Cultivating Questions: A Horsedrawn Guidance System

Market gardening became so much more relaxing for us and the horses after developing a Horsedrawn Guidance System. Instead of constantly steering the horses while trying to lay out straight rows or cultivate the vegetables, we could put the team on autopilot and focus our whole attention on these precision tasks. The guidance system has been so effective that we have trusted visiting chefs to cultivate the lettuce we planned on harvesting for them a few weeks later.

Cultivating Questions: Alternative Tillage & Inter-Seeding Techniques

Our intention is not to advocate the oddball living mulches we use with this single row inter-seeding system, but just to show how it is possible to utilize the between-row areas to improve insect habitat, reduce erosion, conserve moisture, fix some nitrogen, and grow a good bit of extra organic matter. If nothing else, experimenting with these alternative practices continues to keep farming exciting as we begin our twentieth season of bio-extensive market gardening.

Cultivating Questions Canada Thistle

Cultivating Questions: Canada Thistle

According to Walter Conrad Muenscher’s 1935 classic handbook, Weeds, “The Canada thistle is one of the most feared weeds in the United States.” Judging from the number of desperate requests we have received on how to deal with this prickly perennial, Canada thistle still strikes terror in the hearts of innocent farmers across the country.

Cultivating Questions Compost

Cultivating Questions: Compost

How much compost to use for growing produce may be a more pressing question for many growers than the timing of application. Soil testing, crop recommendations, nutrient budgeting and field observations are some of the common methods for determining compost rates. Although we have used all of these tools over the years, our guiding principle has been kind of arbitrary: we use the manure produced by our work animals. With three to four horses for 3 ½ acres of vegetables, that comes to one horse per acre and a current application rate of 5-6 tons/acre.

Cultivating Questions

Cultivating Questions: Concerning the Bioextensive Market Garden

One of our goals when we first started farming here was to develop the farm as a self-contained nutrient system. Unlike the almost complete recycling of nutrients which can take place on a livestock operation, we are always amazed – even a little disturbed – to see how many tons of fertility and organic matter leave the market garden each year with so little returned to the good earth.

Cultivating Questions Counting Beans While Preserving the Grace

Cultivating Questions: Counting Beans While Preserving the Grace

Although we were excited about being involved in this comprehensive research project, we must admit we had mixed feelings about doing the NEON enterprise budgets right from the start. Our reluctance was not due to going public with the numbers, but because economics has never been a driving force behind the goal setting and decision making we use on our farm. Right livelihood has always been a higher priority than profit. Consequently, most of our management practices have been based on what seems right for the land, for the animals, for our customer, ourselves, and the larger society – realizing all along that, being human, we will never get it absolutely right.

Cultivating Questions Cultivator Setups and Deer Fencing

Cultivating Questions: Cultivator Set-ups and Deer Fencing

We know all too well the frustration of putting your heart and soul into a crop only to have the wildlife consume it before you can get it harvested let alone to market. Our farm sits next to several thousand acres of state game lands and is the only produce operation in the area. As you can imagine, deer pressure can be intense. Neighbors have counted herds of 20 or more in our pastures.

Cultivating Questions Diary of a Minimum-Till Horse Farmer

Cultivating Questions: Diary of a Minimum-Till Horse Farmer

Wednesday, April 16 – With the help from a friend who made the mistake of volunteering to help out this morning, we cut up 350 lbs. of seed potatoes and then handplanted the early crop of Dark Red Norlands, Kennebecs and Carolas in seven rows along the north side of field 6. This was the first time we had tried ridge-tilling potatoes and it worked slick, using basically the same procedure as we used for ridge-tilling the peas except making the planting furrow deeper.

Cultivating Questions Direct Marketing

Cultivating Questions: Direct Marketing

An evolving diversity of markets has been essential to the survival of our small business. The marketing mix has changed dramatically over the years as a result of both Opportunity and Necessity. The constantly changing mix of crops on our farm also reflects the ongoing balancing act between our market niche, our growing niche, and our own personal preferences.

Cultivating Questions

Cultivating Questions: Follow-Up On Phosphorus

We like to think that the bio-extensive approach to market gardening minimizes the risk of overloading the soil with nutrients because the fallow lands make it possible to grow lots of cover crops to maintain soil structure and organic matter rather than relying on large quantities of manure and compost. However, we are now seeing the consequences of ignoring our own farm philosophy when we resorted to off-farm inputs to correct a phosphate deficiency.

Cultivating Questions Going Single

Cultivating Questions: Going Single

Going single did not occur to us until we began receiving questions from prospective teamsters who felt it would be more manageable and economical to get started with a single horse than a team. After 29 years of market gardening with two or more horses, our impetus to try out one-horse farming was not a question of management or economy, but due to the radically diverging horse temperaments on our farm.

Cultivating Questions Grow Your Own Mulch

Cultivating Questions: Grow-Your-Own Mulch Part 1

For the past 25 growing seasons, we have used the dryland practices described in this article to direct seed and transplant vegetables all season long without irrigation. Of course, rainfall has been necessary to finish out some of our longer term crops, and yields have generally been better in wet weather. Nevertheless, we consistently get good stands of produce without precipitation or watering in the plants, and our income from dryland fruits and vegetables has increased every year without expanding acreage. Although not a substitute for irrigation, the following moisture preserving ideas may possibly be helpful to growers making do with limited access to water or simply desiring to reduce the size of their hydrological footprint.

Cultivating Questions Grow Your Own Mulch Part 2

Cultivating Questions: Grow-Your-Own Mulch Part 2

In the Summer 2008 SFJ we reported on our initial experiment using the fallow field cover crops to generate enough mulch materials for a 380’ row of un-irrigated winter squash. Encouraged by the excellent crop growth and yield despite the dry, hot conditions of 2007, we repeated the experiment the following years, trying to determine the optimum ratio of land in straw producing cover crops to cash crop area. In 2009, we finally got it right: we seeded a 36’ wide strip of rye and medium red clover in September of 2008, then, in April, 2009, we skim plowed a 12’ wide area in the middle of the overwintering cover crops for planting the winter squash.

Cultivating Questions Grow Your Own Mulch Part 3

Cultivating Questions: Grow-Your-Own Mulch Part 3

To weatherproof more of the market garden in 2011, we tried a variation on the grow-your-own mulch system we developed for producing winter squash in the fallow fields. We discovered it was possible to mulch row crops like tomatoes, peppers, carrots, onions and leeks by moving windrows of rye into the pathways. Although awkward to handle at first, we soon got the hang of picking up an 8-10’ length of twisted rye straw in our arms and walking it from the fallow lands into the adjacent vegetable field.

Cultivating Questions High-Value Cover Cropping

Cultivating Questions: High-Value Cover Cropping

Our winter workshops seem to generate a lot of interest in bioextensive market gardening among young growers. However, we sense an undercurrent of frustration because many of the participants do not have access to enough land to fallow half of the market garden. We hope that the following list of speculative suggestions will provide some encouragement to new vegetable farmers who cannot afford to take land out of production but want to take advantage of the bioextensive principles of rotational cover cropping, minimum-depth tillage, and bare fallowing.

Horsedrawn No-Till Garlic

Cultivating Questions: Horsedrawn No-Till Garlic

We were inspired to try no-tilling vegetables into cover crops after attending the Groffs’ field day in 1996. No-tilling warm season vegetables has proved problematic at our site due to the mulch of cover crop residues keeping the soil too cool and attracting slugs. We thought that no-tilling garlic into this cover crop of oats and Canadian field peas might be the ticket as garlic seems to appreciate being mulched.

Cultivating Questions No-Till Garlic

Cultivating Questions: No-Till Garlic

One reason the no-till garlic may have been able to produce such a massive root system was due to the undisturbed soil being riddled with earthworm holes. Not wanting to destroy the beautiful soil structure created by the earthworms, we prepared the harvested garlic patch for planting a cover crop by fencing in our small flocks of laying hens to shred-and-spread the mulch of wheat straw in the no-till pathways. The birds also lightly tilled all this moisture conserving organic matter into the surface of the soil so a pass or two with the springtooth harrow was all that was necessary before seeding the winter cover of rye.

Drifting Wonderfully Portrait of a Plain Farmer

Cultivating Questions: Portrait of a Plain Farmer

The first balers were so large and clumsy, no one ever thought you could pull them with horses. So the church never put a ban on balers. Then the small pick-up balers came in and the farmers pulled them with their horses. The Amish have adopted just about everything that will pull with horses. It’s hard to say why one settlement made certain restrictions and others didn’t, why some have worked and others haven’t. I guess you’d just have to say it’s the will of the people.

Cultivating Questions The Cost of Working Horses

Cultivating Questions: Portraits of Four Horse-Powered Produce Farms

Thanks to the many resources available in the new millennium, it is relatively easy for new and transitioning farmers to learn the business of small-scale organic vegetable production. Economic models of horse-powered market gardens, however, are still few and far between. To fill that information hole, I asked three experienced farmers to join me in tracking work horse hours, expenses and labor over a two-year period and to share the results in the Small Farmer’s Journal.

Preparing the Orchard Site

Cultivating Questions: Preparing the Orchard Site

We plowed up a narrow contour strip wrapping around the south side of the market garden with the idea of eventually expanding production. Since the east end of this field seemed too steep and stony for vegetables, we decided that this site would be more suitable for a small orchard. Although we had no experience managing fruit trees, we were inspired to plant enough apples to meet our own needs after seeing Soil Conservation photos from the 1930’s which indicated a well established orchard on this same sidehill site.

Cultivating Questions Ridge-Till Retrospective

Cultivating Questions: Ridge-till Retrospective

Originally developed in the Midwest as an alternative to chemical no-till which aided soil warming and mechanical weed control, we adapted ridge-tillage to horsedrawn market garden production by attaching the rough equivalent of a ridge-till sweep to the middle of the riding cultivator. We initially used a cast-off roto-tiller middle buster found on the farm, then upgraded to a heavier duty customized 12” sweep, and finally settled on a 10” furrower purchased from Agri-Supply.

Cultivating Questions Ridge-Till Revisited

Cultivating Questions: Ridge-Till Revisited

Delay ridge building until early fall so that the cover crop on the ridge does not grow more than 12” tall before winter. The residues from a short cover crop will be much less challenging to cultivate than a tall stand of oats, especially if tangly field peas are mixed in. Waiting for the winterkilled cover crop residues to breakdown as long as possible before ridge-tilling in the spring will also make cultivation much easier until you gain familiarity with the system.

Cultivating Questions Rotation Cover Cropping for the Small Fruit Orchard

Cultivating Questions: Rotational Cover Cropping in the Small Fruit Orchard

Cane fruit are among the most moisture demanding crops in the market garden. So, if irrigation is not available, it is essential that the cover crops grown between the rows do not compete with the berries for moisture. For example, a cover crop of oats and Canadian field peas planted right after the harvest of summer bearing raspberries would not compete with the cane fruit during the main growth and fruiting period.

Cultivating Questions The EasyCut System

Cultivating Questions: The EasyCut System

When touring Tony and Fran McQuail’s horsepowered farm outside of Lucknow, Ontario, we noticed something strikingly different about their horsedrawn mower. Every other knife section was upside-down! Following the example of their Amish neighbors, Tony had converted the sicklebar mower to the SCH EasyCut system manufactured by S.I. Distributing. He explained that the alternating face-up/face-down sections balanced pressure on the knife, preventing it from bending or breaking. More importantly, the heavy duty enclosed guards maintain the critical scissor-like action for smooth, carefree mowing without the need for constant adjustment.

Cultivating Questions the Well-Being of Small Farmers

Cultivating Questions: the Well-Being of Small Farmers

The Gregson’s question about sustaining the health and well-being of farmers kind of hit home as I had to learn how to contend with a chronic digestive disorder when we first started farming here. While this minor handicap definitely limited our farming efforts, it also helped us to plan some slack into our operation right from the beginning. It forced us to focus our energy where it would be most effective and encouraged us to rely more on observation and management than muscle to get the job done – lessons we might not have otherwise learned until later in life. As a result, we may have been slower than most in bringing the market garden into full production, but our limitations, in a round about way, may have encouraged us to bring some biological efficiencies into play which have made the work easier and more rewarding in the long run.

The Woodfired Bottom-heated Greenhouse Bench

Cultivating Questions: The Woodfired Bottom-heated Greenhouse Bench

It took several incarnations to come up with a satisfactory design for the bottom heated greenhouse bench. In the final version we used two 55 gallon drums welded end-to-end for the firebox and a salvaged piece of 12” stainless steel chimney for the horizontal flue. We learned the hard way that a large firebox and flue are necessary to dissipate the intense heat into the surrounding air chamber and to minimize heat stress on these components.

Cultivating Questions Weed the Soil Not the Crop

Cultivating Questions: Weed the Soil Not the Crop

Many sustainable growers subscribe to the philosophy of “feed the soil, not the plant.” Our whole farm approach to weed management follows the same line of thinking – we call it, “weed the soil, not the crop.” Instead of relying on the cultivator or the hoe to save the crop from the weeds, we use cultural practices, including cover cropping, bare fallow periods, rotation and shallow tillage, to reduce the overall weed pressure in the soil. One result of this proactive strategy is we no longer depend on the cultivator or the hoe to grow certified organic produce. “Weeding the soil” has also enabled us to use reduced tillage and living mulches without compromising weed management.

Cultivating Questions Winterkilled Cover Crops for a Mild Climate

Cultivating Questions: Winterkilled Cover Crops For A Mild Climate Part 1

Our mild climate makes it too easy to overwinter cover crops. Then the typically wet springs (and, on our farm, wet soils) let the cover put on loads of topgrowth before getting on the soil. Buckwheat is the only crop that I can be certain will winterkill. Field peas, oats, annual rye and crimson clover have all overwintered here. Any suggestions?

Cultivating Questions Winterkilled Cover Crops for a Mild Climate Part 2

Cultivating Questions: Winterkilled Cover Crops For A Mild Climate Part 2

Finding just the right cover crop-tillage combination for crops planted the last half of June has always been a real challenge in our location. While surface-tilling mature rye and vetch in May works well for fall crops established in July and August, this cover crop-tillage combo does not allow enough time for decomposition and moisture accumulation for end-of-June plantings.

Getting Started Behind the Plow

Getting Started Behind the Plow

Leo initiated the circle letter discussion on plowing in their very first letter. Already familiar with turning ground with the sulky, he asked for tips on taking the first steps behind the walking plow. The following advice may not be complete, but it is unique in that it combines the fresh impressions and lessons of teamsters who first put their hand to the plow this past year with the seasoned experience of those who have been walking the furrow half of their lives.

Going STIR Crazy

Going STIR Crazy

A big focus of tillage for our dryland market garden is improving rainfall infiltration and moisture retention. Beginning with skim plowing in the early 80’s, we have added a half dozen shallow tillage practices to maintain moisture conserving residues in the top of the soil. Recently, we were introduced to an objective method for measuring and comparing these moisture preserving practices, thanks to joining the Soil Health Benchmark Study conducted by the Pennsylvania Association for Sustainable Agriculture. One of the benchmarks for this research project, which includes over 60 vegetable, grain and dairy farms, is tillage intensity. This numerical index is based on the Soil Tillage Intensity Ratings developed by the Natural Resources Conservation Service.

Horsedrawn Equipment Accessories

Horsedrawn Equipment Accessories

In the Winter 2016 SFJ, we briefly noted equipment modifications to make fieldwork easier and safer for Eric as he recovered from a debilitating autoimmune disease. Thinking that these add-ons might be of interest to other teamsters, we decided to briefly describe the three we consider valuable now that Eric has regained most of his strength and balance.

HCL How Many Horses

How Many Horses?

by:
from issue:

One of the most frequently asked questions by aspiring teamsters is “how many horses will I need for my farm?” Judging from the following circle letter responses to this very topic, three horses – a team and a spare – would be ideal for a market garden, and four to eight work animals should be sufficient for a livestock operation, where a significant acreage of hay and field crops are harvested.

Mower Modifications for Cover Crop Cocktails

Mower Modifications for Cover Crop Cocktails

We have a double standard for planting density in the bio-extensive market garden. We plant all the vegetables in widely spaced rows to insure plenty of moisture, fertility and air circulation for each plant. For the cover crops in the fallow lands, we take just the opposite approach, seeding at a high density to quickly provide ground cover, weed suppression, and biomass. One reason we have been slow to adopt cover crop cocktails is the very low recommended seeding rate — sometimes as little as 30 lbs per acre — in order to give all of the different species in these diverse mixes lots of room to grow. The mental shift to planting cover crops at a density comparable to our widely spaced vegetables has not come easily.

Purslane, Portahoopies and Plow Planted Peas

Purslane, Portahoopies and Plow Planted Peas

For those not familiar with this tasty, nutritious weed, purslane can be a real challenge to manage in vegetable crops for a number of reasons. The seeds of this weed remain viable for many years in the garden, and generally do not germinate until hot weather — that is, after many of the market garden crops have already been planted. To make matters worse, this succulent plant often reroots after cultivation. Purslane also grows so close to the ground that it is impossible to control by mowing.
