The Rural Voice, 1983-05, Page 8Another View: Ecological Farming Lawrence Andres, newly -elected president of the Natural Farmers Association of Ontario at home on his farm in Kincardine township. by Valerie Bolton Biological farming is the cutting edge in the future of agriculture. It is the fertility of our soil on which the future of the human race depends. This was the message received by 140 people attending the 1st Annual Spring Organic Growers Conference held in Ethel in April. The day long program was co-sponsored by the Natural Farmers Association of Ontario and Oak Manor Farms. "The viewpoint of organic, biological or ecological farming is that massive amounts of artificial fertilizers, pesti- cides and herbicides, the predominance of monocultures and bad tillage practices are destroying the soil" stated the first speaker, Joe Smillie, an agronomist from Weedon, Quebec. Complementing his presentation with slides, he explained "The soil is a teeming universe of busy micro-organ- isms that feed us. Soil life supports all plant life which in turn feeds the animals. It follows that if the soil is nutritionally deficient, unhealthy or even toxic, this is passed along to us through the food chain." The methods of biological farm- ing are not a return to farming practices of the 1920's but a combination of the PG. 6 THE RURAL VOICE, MAY 1983 newest scientific advancements in soil management and the well learned les- sons of centuries of farm practices. "Chemical farming is the fad not biological farming" Smillie stated. He explained the simplicity of creating high quality compost for the promotion of healthy soil on a farm scale. With the equipment presently on your farm, a tractor, front end loader, and power take -off manure spreader, he and a couple of other farmers were composting as much as 100 tons of compost in one day. "Composting is also necessary for the creation and preservation of soil fertility. All plant and animal waste are prime ingredients for the creation of active humus." Smillie described the benefits of 'catch' crops in organic management. These are seedings made after the cash crop harvest that are tilled into the soil for green manure. He warned farmers of plowing in green manure which would simply rot in the ground. "You must disc it down lightly on a sunny day. When brown, disc it in again." He described good farm management often meant sensitive timing. Joe Scrimger, a farmer associated with the Michigan Organic Growers Associa- lion, presented a slide show on the tillage methods he uses on his farm. He stressed the importance of patience in his tillage program. "Disc, leave set and chisel plowing". Bio -dynamic farmers recognize there is increasing evidence that plowing, gen- erally speaking, is a harmful method of tillage. Smillie said "Plowing kills off aerobic bacteria and acidifies humus by burying his productive soil layer (the rhizosphere) six or more inches into anaerobic conditions. Among other bad effects plowing cuts off capillary water movement to the surface and creates a hardpan below the surface." Scrimger stated he only chisel plows when soil compaction calls for it. Otherwise, discing is adequate. "I never till the soil without walking over the land and determining what is indicated." To control weeds, Scrimger cultivates several times, preferring hot sunny days( for maximum weed kill. "I don't really have any problem with weeds, the few we have don't interfere with the crop yield." A crop of weeds tells him he worked the soil a bit wet. Weeds can also be an indicator of soil imbalances or a defi- ciency. Quack grass for example, is an indicator of a calcium deficiency. The audience laughed when he boasted of the manure aeration system on his farm and flashed a picture of a couple of pigs in the composting yard. He concluded his presentation by exhorting farmers to manage the living organisms beneath the soil with as much management skill and care given the cattle grazing on the surface of the land. The afternoon session began with Bernard Hack, a bio -dynamic mixed farmer from the Kincardine area outlining the challenge of transition to organic farming. The three goals of transition were how to get full fertility, manage weeds and develop a healthy soil. "It is with the growing incidence of human ill health that we are being led to organic practices. We will never grow healthy plants on an ill soil, and we will never have healthy animals or people relying on unhealthy plants." He advised that all farms should plant 20-30 per cent of their cropland in (nitrogen fixing) legumes and a farm in transition should be planting even more legume crops. He recommended cow manure as the best substance for making
