The Rural Voice, 1980-08, Page 7But while most of the eroded soil may be caught it is not as likely that the waste material transported to the water with it has been held up. The need for controlling measures is everpresent. There are number of techniques that can be used to hinder the erosion process, and many farmers are familiar with them and use them. Windbreaks are one course that can be taken, and the tree -lined barriers are familiar sights in rural areas. There are other natural courses that can be taken to head off erosion. "When grain land is open, from late August to September, you plant a cover crop," says Feldman, "That prevents erosion and improves land quality." Besides taking steps to ease the erosion of land with crops and planting, one of PLUARG's concerns is with ploughing fields too close to the edge of open waterways. This was another question in the PLUARG survey, as they sought to determine to what extent farmers were cultivating close to drainage areas. They found 73 per cent of farmers with waterways on their property were ploughing within 20 feet of the drainage spot. The report considered this result serious, "given that the closer cultivation is carried out to a watercourse the greater is the likelihood that detached soil particles will be carried to receiving waters." ECONOMIC INCENTIVES The report continues later: "Certainly an intensive program of farmer education concerning the HAA (hydrologically active areas) will be necessary, coupled with a program of economic incentives to encourage farmers to return this cultivated land close to streams and ditches to uses where soil disturbance is minimized." Another of the PLUARG suggestions was zero tillage, and it noted the practice has been successful in parts of the United States. However, neither Feldman nor McIntosh think it could be successful in this part of the country. McIntosh points out that southwestern Ontario soil is different from that where zero tillage has worked. "If you have sandy soil you can do it," he says, "but if you have zero tillage, you need more fertilizer, herbicide and insecticide patrols." per cent of Ontario farmers do spread some of their manure on frozen land. The report notes that the practice is harmful to the water system and also is of no benefit to the farmer. "Nutrients in this manure may be either volatized or carried off in runoff during periods of snowmelt," it says. "This situation not only results in degraded water quality but also in a loss of nutrients to the farm operation." In at least one instance the Ontario government, in newspaper promotions, encouraged better care and usage of manure by emphasizing that manure was an agricultural asset that shouldn't be wasted. GETTING RID OF MANURE "We tend to think in terms of getting rid of manure," says Feldman, "rather than fertilizing our fields." The work and time outlay involved in soil conservation and anti -pollution advances is undoubtedly a long term project, and the fact that the IJC or PLUARG have no political clout won't speed the process. "The problem with the UC is they have no power at all," says McIntosh." They do research into what exists, and they have two national, and several state and provincial governments to deal with. "The LNC should be more politically active, perhaps with lobbying groups. Press releases just end up in the garbage." Another factor inhibiting a speedier improvement has to do with the nature of the farming industry. By definition, its participants are spread out, and aside from federations, for example, it has no concentration of power. That makes the distribution of information, and defending themselves politically more complicated. "Because farmers are a more diverse group," says McIntosh, "governments can pass legislation which affects agriculture easily. Now the Ontario Federation of Agriculture is acting as a watchdog for interests involved with agriculture." Inevitably portions of the farm community are going to be skeptical of the findings of reports such as that of PLUARG, and Feldman notes that it may be justified. "It's government," he says. "For example, paving over "Pollution is ... a political football .. . sometimes farming is used as a scapegoat." "You have to kill vegetation with herbicides, and that leaves plant residue," says Feldman. "That's self defeating, and zero tillage causes yield drops. Farmers would love not to have to till." Another of PLUARG's concerns is the spreading of fertilizer and manure on frozen fields. Feldman suggests the practice is simply a lack of common sense. "You have to utilize manure instead of buying fertilizer'," he says. "To get its value, you've got to incorporate it with the soil and at the right time; you don't waste it by using it when the ground is frozen." In spite of this, another of the PLUARG studies found that 36 Niagara is OK, but then the government comes and tells us we have to save land from erosion. That's inconsistent. "Pollution is more of a political football. I think sometimes farming is used as a scapegoat." In the end, it's a problem we all need to be concerned about, and we need to be willing to cooperate with the remedies. PLU 1RG discovered in one of their surveys that the majority of fanners surveyed favoured voluntary efforts from the agricul ural community to clean up water pollution. Thv'. was three years ago. An IJC report this year said regular ons will be needed if voluntary approaches in land use practices do not improve. THE RURAL VOICE/AUGUST 1980 PG. 5
