by John B. ClarkArmed with an interdisciplinary science doctorate, life-long
ecological observations, farming in my blood, ten years of entrepreneurial tenure, a date
of birth preceding the modern "pesticide revolution" by 15 years, a
mortgage-leveraged farm purchased in the mid-70's, and no visible agency guidance in
sustainable agriculture, I set off in 1976 at age 39 to try "our" hand at family
farming. Like most beginning farmers, I was an obvious target for the agrochemical
producers, each of whom had "all the formulas" for secret success. However
because I new it could be done without them, we eschewed pesticides from day one.
All the "experts" forecasted failure.
Since I was confident as a biochemist that very soon pesticides would migrate to the
aquifers just as they would through a chromatographic column in the laboratory, and since
I also surmised that foreign (to nature) molecules from "crop protection"
chemicals would very certainly be toxic to at least a few of the thousands of metabolic
pathways making up the food chain and providing ecological balances, I saw no alternative
but to proceed as if my farming career would be an ongoing experiment, mixing modern
equipment and genetics with the good farming practices I had watched my grandfather and
father use.
Thus began Roseland Farms, pesticide free since 1978 on 645 acres (and additionally on
1,115 acres since 1980) in southwestern Michigan, 20 miles northeast of South Bend,
Indiana.
Since 1985 we have also been free of soluble chemical fertilizers. We started
with land that had been on the chemical treadmill, though not as long as many of the area
farms. Though we considered this a not-so--hidden defect, it did provide us with a
baseline value for productivity on the "treadmill" of our operation.
In 1977, the tillable base of the original 645 acres was rented to the resident
chemical dairyman, since we were not financially capable of taking over operation of the
farm the first year. Thus we were able to observe first hand the performance of
chemicals on our acreage that year. It was not very impressive, and the dairyman
went bankrupt in 1978, reinforcing our contention that chemical farming was not the answer
to successful farm economics and corroborating our experience with share rental of family
"chemical" farmland in Illinois homestead be exchanged for additional Michigan
acres near our mortgaged farm in 1980 so that we could become the sharecroppers sans
chemicals! And this was done.
We did the unthinkable. We went cold turkey off the pesticide treadmill in one
crop year. Except for some problems in the first year, yields have been comparable
to those of the previous baseline, and in recent years they've been improving over that
baseline. In spite of an outrageous debt level and droughts in '83, '85, '88 and
early '89, we have survived--and then some!
Since then, we have learned that what we did as an independent experiment has been
repeated almost without exception worldwide. The results are almost always the same:
Yields get better as organic practices are continued, and pest problems virtually
disappear. Natural pest controls, which are suppressed in chemical farming, get healthier
and more effective every year. Plant and livestock health improves; soil tilth improves
every year, and so does soil moisture retention.
There are no secrets or surprises, only simple, economical management practices:
long-term crop rotation; leguminous and nonleguminous green manure incorporation;
mechanical cultivation; clipped forages and allelopathic crops in rotation;
------preservation of habitat for-beneficial insects and other natural control organisms.
It all really does work!
Livestock is helpful for efficiency and for utilization of alternative crops, but is
not mandatory for adequate maintenance of plant nutrients. We compost manure for optimum
nutrient and nitrogen recycling, but green manures are more effective than animal manures,
in our experience.
The compelling conclusion to this experiment and its repeatable results in the organic
community is that the highly touted benefit assumptions for pesticide and fertilizer
inputs are nonexistent. These "benefits" are being measured wrongly. The
zero-pesticide baseline is not usually achieved. Test plots are almost always contaminated
with chemical carryover, which suppresses natural controls and distorts the benefit
valuation. For the most part, the federal EPA never even bothers to evaluate benefits;
they are simply assumed to be highly positive.
The public and farmers then get the idea that high crop yields are only possible with
pesticides. Many farmers try to go off the treadmill and fail, because they are not
patient enough to allow natural controls to return to normal (baseline). The favorite ploy
of the pesticide industry is to show fruit from an unsprayed tree in a chemical-controlled
orchard. This is a classic case of the skewed (wrong baseline) test plot just
described-which is used -to justify pesticides. Actually, this example proves the self-
defeating nature of chemical pest control.
Most credible organic certification standards include a three-year absence of
pesticides because it takes at least this long for pesticide residues to fall to
predominantly natural-control levels. However, from the standpoint of victims of
environmental illness or multiple chemical sensitivities, three years may not be long
enough. In addition, "natural" insecticides such as rotenone, pyrethrins, or
neem, which are allowed in many organic programs, should be avoided by El victims.
Also, these suppress natural controls and therefore generate their own perpetual
demand, like synthetic pesticides.
HEAL members and others who care about good health should avoid use of--or food grown
with-even these "benign" pesticides. Ask store managers to find out what
chemicals are used on the foods they are selling; check to see what organic standards are
being adhered to by growers of organic produce, meats, and grains.
"The compelling conclusion to this experiment and its repeatable
results in the organic community is that the highly touted benefit assumptions for

We need to stop dignifying the myth of the benefits of pesticides, and we need to stop
pretending that there can ever be safe"---or even effective-poisons. There are too
many thousands of species of insects for this ever to apply. "'Close" only
counts in horseshoes. Pesticide-free farming has to be just that--totally free of
pesticides.
Roseland Farms began a direct marketing program (primarily beef to stores in 1985. El
victims have found our products to be completely clean, and this "test market"
is a far more sensitive assay for pesticide residues than any chemical analysis currently
available. EPA does not seem to recognize the existence of environmental illness or its
victims. The sad truth of all this is that all the risks associated with pesticides are
unnecessary risks. Safer, nontoxic alternative practices exist and work. The
Roseland Farms experiment demonstrates this, without a doubt.
