The Wingham Advance-Times, 1984-03-21, Page 376 = The Farm Edition, Week of March 21, 1984 Reduce problems with better tillage Larger, more powerful farm equipment speeds tillage, seeding and harvesting, but it can also cause increased soil compaction. "Soil compacti n in the short term makes it more difficultor farmers to prepare a seedbed and may increase the power and fuer requirements of tillage operations," says Dr. Charles Baldwin, Ridgetown Col- lege of Agricultural Technology soils scient- ist. "But in the long term the problems are more severe because crop yields and profits may suffer." Heavier equipment is often the cause of increasing soil compaction problems in Ontario. Three to four decades ago, the average tractor weighed about 2.7 tonnes (3 tons). Now, tractors weighing 18, 27 and 36 t (20, 30, 40 T) are not uncommon. To reduce soil compaction, examine the seedbed preparation and determine the least number of passes across the field necessary to do the job. "Make the seedbed as shallow as possible," says Dr. Baldwin. "This will preserve the moisture in the soil and reduce the fuel energy required. Don't lose the moisture you have in the soil in order to get the seed in the ground." Wait until the soil is ready before you begin tillage operations. Experience will tell you when the moisture level is right. "Unfortunately, today's larger and more powerful equipment allows us to get on the soil when it is still too wet," says Dr. Baldwin. "Now, it is a matter of ` self discipline for the farmer to wait until the soil is ready." The fin implement that heads the list in soil compaction is the tandem disk. Although it cuts well into the soil, it 'contacts only a small proportion of soil, thus it exerts very high pressure 8 to 12 cm (3 to 5 in.) down into the soil. The surface shows a loose open structure, but below the soil may become very compacted. "Field cultivators, such as mulch plows or chisel cultivators, are the least .compacting implements," says Dr. Baldwin. However, although they reduce compaction, they must still be used with discretion and must fit in with the individual's farming system. To determine whether your soils are becoming compacted Dr. Baldwin suggests watching for the following symptoms: When the soil begins to warm, the rate of water disappearance is slower; you may notice a ponded area where there has never been a problem before; the soil has a tendency to dry out more than normal; it may appear crusty or cloddy; you may also notice that it is more difficult to prepare a good seedbed than it was in past years. Once the crop is in the ground, watch for sickly plants. Plants that are stupted or off colour (reddish or yellowish) May be a symptom of soil compaction. Check the roots of the plants too. Misshapen roots are another common symptom. "Farmers must be able to read their soils," says Dr. Baldwin. "We must watch soil carefully to make sure we don't harm it.'' f Wetlands aren't wastelands Ontario's largest provincial conservation organization has presented the Ontario government with a 10 point action plan to. save the province's dwindling wetlands. The 46,000 , member Ontario Federation of Anglers and Hunters (0. . . c aims at over five million acres of valuable wetlands have been drained or filled in southern Ontario, alone and are likely lost forever. In a Position Paper and letter to all M.P.P.s, the federation is asking that wetlands be saved through tax incentives made available to land owners that are comparable to the Farm Tax Rebate Plan, and when long term management agree- ments (20 years) are reached, that additional incentives be provided. The federation insists that a Benefit/Cost Analysis be included in an environmental Assessment on each and every wetland under consideration for drainge, and that no drainage of any wetland be permitted unless, subjected to a proper evaluation of the impacts. A moratorium was called for on any project affecting a wetland for one full calendar year to allow • full ' seasonal evaluation. This sportsmen's federation also wants the government to do a better job of. informing the general public, particularly land owners, of the importance of wetlands. Since the first settlements, wetlands have been thought of as wastelands and have been drained and,filled in the name of progress. only a fraction of the original wetlands have escaped .conversion to farm- land, town sites, cottages an ' to . ustrta parks. The federation is alarn ed at the general, public's indifference to this valuabt re- source that provides many benefits, free of charge.,,Wetlands are described as land that is seasonally or permanently covered by shallow water. The five general classes of wetlands in Ontario are bogs, fens, swamps, marshes and shallow open waters. Wetlands have the ability to absorb large amounts of water and release it slowly 'over a period of time. This alleviates flooding during high water and augments low flow during drier months. Wetlands are very effective pollution fighters, acting as settling and filtering basins, collecting silt and pollutants. They are also indispensable in wildlife and fish production. Most •animals must spend at least some part of the year in wetlands. The federation is a 55 year old conserva- tion organizationdedicated to the wise use and management of Ontario's' natural resources. Certified seed has benefits As inflation continues •to put pressure' on crop production effiency, more growers will be •measuring the benefits of Certified seed against the perceived dollar savings of using bin run seed. • It is a fact that still over 80 per cent of our cultivated land is sown with non pedigreed seed each year. This could be one ofthe most expensive traditions on the farm because a denies the farmer maximum yield and quality, and perpetuates weed and disease problems which bite further into his pocketbook. Evidently, many farmers still believe they can save money by hauling bin grain to the elevator to have it cleaned and hauling it back to the farm for planting. This has proven to be false economy. When time, trucking and fuel costs, and the elevator cleaning process are all considered, it would be their advantage to sell the grain and buy good, clean, bagged or bulk Certified 'seed. Thes is especially true in western Canada where growers may deliver up to 600 bushels of over quota grain and use the proceeds for the purchase of Pedigreed seed wheat, uai}, barley. flax or rapeseed. This program offers growers increased opportunities' for marketing grain and improving future crops. When one considers fuel, fertilizer, pesticides and all other input costs in crop production, Certified seed is probably the lowest. Yet, it offers one of the highest returns. The small extra cost of buying Certified seed is a guarantee of improved quality, cleanliness from weeds and disease, and good germination. Pedigreed seed is controlled. but strict regulations to ensure the seed is mechanically pure and true to type. Well cleaned seed contains a greater precentageof large kernels which has proven to produce healthier and more vigorous plants than small kernels. With new varieties being introduced every year, many of which are developed in response to current market conditions, Certified seed gives growers access to the highest yielding. top performing varieties available. Growers aiming for better return on their crop production investment find that Certi- fied seed doesn't cost, it pays... and they use it for all 'Cs worth.
