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.
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.
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.
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.
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.
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.
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.
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.
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?
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.
