Woe�c& 10 - THE IETHBK1DGE HERAVD - Friday, January 29, 1971 'llc>rald LETHBRIDGE RESEARCH STATION Better laying results Chicks take to dim light By C. S. CLARK. Regional Poultry Specialist Conserve trash on fallow D. T. ANDERSON, Agricultural Engineer Trash covers for control of soil erosion last lungers when chemicals are substituted for tillage in a summer-fallowing program. Resistance to soil erosion by wind is related to the quantity of trash on the soil and to the positioning of the material. Trash provides greater protection when it is upright than when it is flat. Various chemical and cultivation practices can be rated for soil erosion protection on the basis of quan tity and position of the trash. At the Lethbridge Research Station we measured the amount of spring wheat trash after harvest, during the fallow season, and before preparing the seedbed in the spring. Four different summer fallowing methods were studied. Where chemicals were used to control weeds and no cultivation was done, 90 per cent of the original weight of stubble and straw was conserved. Furthermore, Ihe stubble remain ed upright and maximum pro tection from soil erosion by wind was obtained. Where chemicals were used in the spring and fall to control broad-leaf weeds and a wide-blade cultivator was used to kill those weeds that were resistant to herbicides such as 2,4-D, about 65 per cent of the trash remained. Most of the stubble remained upright. Where chemicals were used and the fallow was cultivated once with a one-way disc, only 30 per cent of the trash was conserved. The loss resulted from the tillage operation and from winter weathering. The trash was flattened and gave poor wind protection. Where only a wide-blade cultivator was used for weed control, four to five tillage operations were required, and 65 to 75 per cent of the original trash remained. Weathering during the winters preceding and following the fallow season each reduced the trash by an additional 10 per cent; hence only 45 to 55 per cent of the original trash was conserved. The trash cover was usually flattened by the four or more operations required to control the weeds. The chemical fallowing with no cultivation conserved the most trash and provided the best protection. Tillage with a wide-blade cultivator combined with the application of chemicals for weed control rated second. Cultivations with the wide-blade cultivator conserved the trash reasonably well but, because of the number of operations required for weed control, the trash was flattened and the practice must be rated third. One cultivation with a one-way disc and the application of a herbicide gave the poorest protection against erosion on fallow land. Dr. D. B.

Poultrymen in any lighting system spac have been supplementing natural light for years and more recently they have learned that by excluding nearly all natural light they have a better control of both light intensity or brightness and duration of the photoperiod (length of time the light is on) There are two degrees of natural light control, "Brownout," allowing some light infiltration where controlling inten Eggs sold by weight ing between bulbs and location of strings of lights are important. No part of the building must be in shadow and prefer ably the strings of lights must be located over the feed troughs, or between the rows of cages in laying barns equipped with stair - step cages. Spacing between the bulbs must be one and one half times the height above the feed trough.

J. E. Childs, president of Burns Foods Ltd. "Meat packers arc in the same position as the farmer who decides to sell his own hides, as packers do not use the hides, but rather sell them to hide dealers." There is a world market for hides so they usually end up at warehouses in Toronto, Mont- real and sometimes Vancouver. From these warehouses they may go anywhere in Canada or anywhere in the world. Mr. Child said, hides are a standard world commodity and there are standard grades. "Hide prices are world prices, set by world supply and demand, not by the situation in Canada." Hide prices are quoted daily in the Wall Street Journal (and similar publications) according to grade. Eggs are actually sold by weight.

Complete "light - control" is necessary to obtain the physiological effect of changing the length of the photoperiod.

The meeting was called to >rdcr by Vice-President Cheryl Luco and the pledge was led by Cathy Murray and Bev Kraush-er. Roll call was to bring a sample of material and'tell what it was. We made plans to make our nest meeting a pot luck supper, and hold it one of the leaders homes. Mothers could attend. .Anna Boulten gave a talk on My Project Book and Brenda Boulten gave a talk on Noise Pollution. Susan Harker did a demonstration on basting and Patricia Patching and Bev Krausher did a demonstration on table manners. The talks and demonstration were introduced by Cathy Murray and thanked by Pat Lengyel. BEV KRAUSHER -reporter GRASSY LAKE On Jan. 4, the Grassy Lake 4-H Beef club held its meeting in the Chamberlain School at Grassy Lake. The meeting was brought to order by President Betty Ra- chue. The minutes of the previous meeting were read by the secretary, Van Matz. The president read the business letters. They held a discussion on this year's public speaking contest. Rose Anne and Lloyd Sziglii each made an impromptu speech. Geri Knibbs gave a short summary on preparing a speech.

We discussed the quilt we raffled off Dec. 23. The topic of changing the length of meetings was raised, but nothing conclusive was decided. Project books were worked on and the meeting was adjourned for dinner. After dinner, a debate was held on the fashions of shoes and dresses. We then worked on sewing projects'. The meeting was adjourned. PAT BOWEN-reporter $10,000 tractor might receive $4,000 trade - in on a new $10,' 000 tractor. In this case he would actually have to pay only $6,000 for the new tractor, but under the present depreciation method he would be allow ed to claim depreciation on the full $10,000 during the following 7 years. Under the proposed diminishing balance method of depreciation, however, he would be allowed to depreciate only the $6,000 which he actually paid for the new tractor. Similarly, if a fully depreciated tractor was sold for $4,000, the money would have to be included in his current income. Although diminishing balance depreciation rates are usually double those used in the straight lino method (10 per cent instead of 5 per cent for wooden buildings, 20 per cent instead of 10 for machinery without a motor and 30 per cent instead of 15 for motorized machinery) the actual depreciation is calculated each year on the value that is left after the previous year's depreciation has been deducted. For example, the depreciation allowed in the first year on a $10,000 tractor would be $3,000 ( 30 per cent of $10,000). The second year it would be only $2,000 (30 per cent of $7,000). In other words, the amount of depreciation that can be claimed diminishes each year. The net effect of changing from the diminishing balance to the straight line method of depreciation, says Mr. Bayda, would undoubtedly, be that farmers would buy less machinery. The smaller farmer who used to buy second hand mach inery would no longer be able to get it, and so his production costs would go up. Tiie fact that the bigger farmer will be in clined to "make do" with the machinery he has on hand will inevitably slow up the introduction of innovations, thereby de-creas i n g agricultural production efficiency.
