Food Farming and Crop Rotation
We get a lot of
questions about vegetable growing in general, questions about organic
specifically, and questions about farming with both plants and animals. So, we’ve allotted more newsletter space
this season to production issues, and so far have shared details on the soil,
insects, watering, weeds, and of course, the weather’s effect on all of
it. Well, why does organic farming
work? One reason is the employment of
crop rotation, today’s topic.
The acreage at
Elmwood that is suitable to tillage without the risk of erosion is where we
plant the food crops (flatter fields, not the hilly ones). Before this
disruption of the soil occurs, it must be in the right condition to meet the
needs of the ensuing crop. Everything
here starts with alfalfa, commonly referred to as the Queen of forage crops.
Alfalfa is a leguminous, tap rooted, broadleaf plant emerging from a seed about
half the size of a sesame seed. It is slow to germinate and establish itself
when planted in the fall, so we sow a fast growing small-grain like wheat or
barley at the same time. This small-grain grass germinates quickly, holding the
soil, and helps keeps weeds from trying to grow that would compete with the
small alfalfa plants. In early summer,
we harvest the wheat heads, leaving behind the alfalfa. The wheat is considered a nurse crop,
helping to give the alfalfa seed a chance to get established, though eventually
it is used in another part of the operation -- just last week, John harvested
the wheat grain with a small combine.
We can feed the grain to poultry or use the seeds to plant with alfalfa
in a similar method later this fall.
We know this variety of wheat does well on this farm, so saving our own
organic seed is a sustainable key.
The alfalfa will
be cut for hay numerous times for four years to nourish the cattle and sheep in
winter. The taproot of the perennial alfalfa plant will penetrate deep into the
soil, breaking up the harder clayey profiles and retrieving nutrients. Each
time the plant is cut for hay, an equivalent amount of root mass dies, since
there is not enough leaf area to support it all. These dead roots are
decomposed by the microbes, releasing a wealth of nutrients for the new roots
to feed from. It also opens
up channels for air and water to feed the microbes.
In
addition to all of this, the symbiotic relationship the plant has with a beneficial
microbe is the dramatic part of the story. Alfalfa seeds are inoculated with a
specific strain of microbe before planting. The microbe will attach itself to
the root, forming small pink nodules. While the plant is providing safe haven
and nutrients, the nodules are extracting nitrogen from the air and feeding it
to the plant. Any nitrogen produced that is not need-ed by the alfalfa is made
available to other grass plants and soil biota. After four years of this soil
building and animal feeding farming, the land is plowed and tilled to prepare
for vegetables.
Generally,
the high-value, long-season, heavy-feeding crops like tomato, pepper, melons,
and sweet corn are the beneficiaries of this vibrant soil. When they are
finished being harvested, we will plant some of that wheat seed in the fall to
hold the soil, play host to the michorizae fungi, and keep weeds from encroaching.
This wheat cover crop is easily tilled the following
spring for short season crops like greens, broccoli, lettuce, beets, etc. Actually, we can get two crops per year from
this same acreage, as many of these same crops grow well into winter, and the
second planting will hold the soil and provide food for fall CSA shares. The
next spring, this land will be planted to the self-feeders. These are legumes
like green beans, dry beans, and peas. After they are harvested, in comes the
alfalfa and wheat nurse crop, setting up the 7-year cycle to begin anew. A huge benefit to utilizing crop rotation is
that insect pests and plant diseases often get lost in the shuffle, neutering
their ability to hurt the crops.
As members of
the Elmwood Stock Farm CSA, you now not only know where your food is coming
from for the season; you know where it will be growing next year,
and
the next, and the next: a testament to the crop rotation planning that is
necessary to ensure your produce will be healthy, productive, and wholesome. Hopefully, it feels pretty good to know where
your food will be coming from year after year.
