Lethbridge Herald, The (Newspaper) - August 28, 1970, Lethbridge, Alberta J6 THE LETHBRIDGI HERALD Friday, Au0uil 18, 1970 Variety Of Substances Affect Quality Of Water What are the things that af- fect the quality of water and what can be done about them? Water tliat has been contami- nated by bacteria is not safe to drink. The contamination is usually caused by either human or animal excreta. Although it is difficult to test directly for disease producing organisms in the water, other organisms from human and animal wastes can be identified by having a sample of the water tested. Algae in water are not harm- ful but if present in large quan- tities will give the water an unpleasant taste and appear- ance. Turbidity or muddy wa- ter is not harmful either, but most people object to drinking it. The turbidity is caused by fine soil particles that are held in suspension in the water. Decaying organic matter causes an unpleasant taste and odor in water. A charcoal filter will usually improve both. Iron in water is not injurious to the health; but will leave rusty stains on appliances, wa- ter fixtures and clothes. Tea and coffee made from water Potato Improvement Plan Introduced In Alberta Alberta has now introduced a seed potato improvement pro- gram to ensure the continuous production of high yielding, high quality seed potatoes that are free from serious potato diseases. The best strains of disease- free breeding stock have been supplied to the Alberta depart- ment of agriculture by the fed- eral research station in Van- couver. This station is the only one in Canada" equipped to pro- vide seed potatoes that are free from serious disease. The progeny from this breed- ing stock will be checked out in the field, in green houses and in laboratories by the de- partment of agriculture to make sure that the tubers aie free from all serious potato dis- eases. Growers of Eh'te I, II and HI potatoes will be chosen by the advisory committee, and I approved by the prices and marketing subcommittee and the federal plant protection di- vision. To be eligible for selec- tion, a grower must have suit- able land, equipment and build- ings. He must also have the re- quired knowledge and experi- ence and agree to comply with the program regulations. Potatoes from Elite I plots will remain the property of the Alberta department of agricul- ture. Elite H plots will be planted under contract by se- lected growers. These growers will be allowed to sell the pro- geny only to approved potato seed growers and at a price agreed upon by the prices and marketing subcommittee. Elite HI potatoes will again be grown under contract and can be sold only to seed growers approved under the program. containing even small quanti- ties of iron will be different in color and taste to that made with water containing no iron. The iron, which usually comes from the soil, can be removed, but the method of removal var- ies according to the iron con- tent of the water. Nitrates in water are caused by decaying organic matter. The water can be dangerous for both human beings and ani- mals. A high nitrate level in a water supply is often caused by seepage from livestock barns. Calcium or magnesium or both are responsible for water being hard. Soap will not lather in water that contains one or both of these chemicals, and a film will be left on clothes and dishes washed in hard water. Scale formations may appear in water heaters and hot water pipes. Hard water can also cause skin irritations. Water softeners will remove these chemicals. Sodium salts are not harmful in water, but if combined with carbonates to form soda water, they will "pit" aluminum con- tainers. Sulphates are present in the water in some areas of Alberta. More commonly known as Ep- som Sails or Glauber's salts, these sulfates have a laxative effect. It is too expensive or impossible to remove them from domestic water supplies. Lead is rarely found in water, but is poisonous when Anybody who is in doubt about his water or wants to ind out if he can improve its quality should send a sample :o the provincial analyst, 0. S. Longman Building, 6909 UCth Street, Edmonton, Alberta, or his local public health of- ice. Insecticides Essential DR. D. L. STRUBLE, Organic Chemist The effective use of insecti- cides to control crop insect pests is essential for maintaL ing and increasing agricultural production. In the past, the most widely used insecticides have been the chlorinated hydrocarbons of which DDT, aldrin, dieldrin endrin, and heptachlor are thy pressing it between the fin- ger and thumb. A tiny bead oi noisture will be evident at the 30 per cent moisture level of wheat but not at tire 35 per cent evel. Barley with a 35 to 40 per cent moisture content is in the irm dough stage. The kernels should be plump and have ma- tured in the part of the field that is slowest f to ripen. It. is particularly important with malting barley to have the ker- nels uniformly mature. Late maturing patches in the crop should be combined separately. Estimates show that 30 per cent of malting barley samples are rejected because they con- tain immature kernels. Ex- treme care should be used when combining malting barley to avoid hulling and cracking ker- nels. Oats with a 35 per cent mois- ture level are in the medium to firm dough stage. Rye that has a moisture level of 40 to 45 per cent is in the late milk or early dough stage. Although this moisture level seems high, researchers have found that it does not lower the quality or yield of the crop. Rye is quite subject to shatter- ing at a lower moisture level. Rapeseed crops should be swathed when the seeds have turned brown, regardless of whether or not the pods have turned a straw color. If swath- Ing is left until the pods are all ripe, excess shattering is likely to occur. However, to assure maximum oil yield, it is impor- tant that all the seeds be brown before the crop is cut. Hapeseed crops should be swathed as lu'gh as possible so that the stubble provides a good anchor for the swaths. Swaths that are well anchored are less likely to blow away in a high wind. Some farmers firm the ;.waths into the stubble by pulling an empty barrel at- tached to a (rame and axle be- hind the swather, or by pulling a piece o' plywood behind the swillicr. However, this safety measure cannot be used if the crop is loo ripe. Losses from shattering in a rapesccd crop that is not cut until the pods are ripe can be lessened by swathing when there is dew in the early morn- ing or late evening. during the past six months that were eligible for the premium. According to Mr. Macdonald, during the same six month pe- riod producers in the province marketed a total of hogs, of which or 12.8 per cent earned the quality pre- mium with an index of 105 or higher. At the beginning of this year the federal government intro- duced a new grading sys- tem designed to recognize and reward the producer of quality hogs in this country. Although it may be too early to expect results, so far there does not appear to be any appreciable improvement in qualify, and Ottawa is reported to be plan- ning to drop the quality pre- mium at the end of 1970. Dur- ing the current year' there has also been a sharp decline in the number of hogs being placed on test at Record of Performance stations across the country, and this is a fur- ther cause for concern. At a tune when so much emphasis is being placed on quality it's unfortunate that farmers themselves are not making a greater effort to pro- duce and market the premium product that the consumer is demand ing, Mr. Macdonald says. "They have good basic stock and there's any amount of in- formation available on feeding and management. What seems to be lacking, in most cases, is a real desire on the part of many producers, to market 'a product that will meet today's high quality standards." Plan Feed Mill In Manitoba WINNIPEG (CP) One of the most modern feed mills in Canada will be built in Otter- burne, Man., 30 miles south of Winnipeg, Hie Miracle feeds di- vision of Ogilvie Flour Mills Co. Ltd., announced here." Arnold Keys, regional man- ager of the feeds division, said the mill will have a capacity of 200 tons a day, when completed next spring. Construction. is to begin in mid-September. The hen is the only creature that can produce dividends by sitting around.
