Lethbridge Herald, The (Newspaper) - July 24, 1970, Lethbridge, Alberta 10 THE LETHBRIDGE HERAID Fridoy, July U, WO Potassium On Grassland K. K. KROGMAN Soil Specialist Tlie soils of southern Alberta appeal' to contain an abundant amount of available potassium Soil testing laboratories have shown that the exchangeable potassium in these soils ranges from 500 to pounds per acre. Will the available potas- sium be seriously depleted il we continue intensive irrigated cropping? Will potassium fer- tilizer soon be required for irri- gated pastures? These are questions frequently asked. To find the answers to these questions conducted tests in the field and in the greenhouse. We used Chin loam, a medium- textured soil that is typical of our irrigated areas. In the field we found that the available potassium in the soil after five year's under irrigated grass was reduced from 8DO to 400 pounds per acre. The plots had been heavily fertilized with nitrogen and phosphorus to promote maximum production, thus lu'gh utilization of potas- sium. The annual yields were about five tons of hay per acre. rf 11, i s soil were taken into Uie greenhouse and ciujjpea 10 barley and to grass, again under high levels of soil nitrogen and phosphorus. After nine months, the available po- tassium was further reduced from 400 to 300 pounds per acre but remained at this level for the final five months of the test. Even when potassium fer- tilizer was added, yields were not increased. These tests show that the requirement by the grass for potassium and avail- ability were in balance, and that potassium was not in limiting supply for this crop. Therefore, we are quite con- fident that the available potas- sium will not be seriously de- pleted by continuous irrigated cropping and that potassium 'erlilizer will not be required 'or" irrigated pastures in south- ern Alberta tir-e. for quite some C'MON RAY, HURRY UP-Appears to be the expres- sion on the gentleman's face, as he anxiously awaits some of "cookies" vittles at the free downtown breakfasts being held during Whoop-Up Days. Cook Ray Richards, Stirling, chief cook and bottle washer for the 1970 Whoop- Up riders, knows only too well what he is doing? Corn Production On Upswing Quite a number of irrigati farmers in southern Albert will be growing grain corn til rear as an "alternate" cro The present increasing interes Careless Feeding Reduces Profits Substantial rewards can be, and other nutrient requirements isons of breeding groups delibe expected by the average hog producer if he is willing to pay a little closer attention to the ration he feeds, claims an ani- mal nutritionist at the Univer- sity of Alberta. This is parti- cularly true at present when the cost of grains is very low in relation to the cost of supple- ments. In a recent interview Dr. J. P. Bowland said experiments carried out over several years by the University's Animal Sci- ence Department had demon- strated that higher net returns could be realized by feeding ra- tions that fit in with the overall management program of the hog enterprise. The breeding program, the sex of the pigs, the type of buildings and the general stresses to which pigs are exposed all have a rela- tionship to the energy, protein of pigs. In a study conducted durii 1966 to 1968 the gain, effitien of .feed and energy utilizati as well as carcass character tics were studied with t h r groups of pigs chosen to repr sent what were expected to reasonably wide extremes rate of gain and in lean to f ratios in the carcasses.

The pigs were fed either high digestible energy (DE) r tion with approximately 16 kcal DE-lb or a low digestib energy ration with 1150 ke; DE-lb. The high energy ratio was based on wheat while th low energy ration was based o oats with some wheat bran ha anced in both cases with a mix ed protein supplement. The ra Jos of protein, lysine, sulfur amino acids and calcium to d gestible energy were maintain ed at a similar level.in the tw diets. The pigs on the low energy diet consumed a similar amoun of feed but over 25 per cent les digestible energy, gained 0.4 Ib ess per day and required 0. b. more feed per Ib. gain. Al hough the carcasses from the >igs fed the low energy die were leaner, dressing percen age was depressed by approxi mately 4 per cent. On the basu f present feed prices the use f low energy diets as a means improving carcass quality ould not be justified. JJmilingg eed intake on a high energy or ormal type of pig ration is an ther method of improving car- ass quality at the expense of ain. Depending on the breed- ng background of the pigs and ther management factors, lis approach to improved car- asses may prove economical. In the energy experiment, the arrows fed Hie high energy ra- on gained more rapidly than le gilts, and the crossbred pigs ained more rapidly than the ure Yorkshires. On the low en- "rgy diet, the gain differences ssociated with sex and breed- ig groups disappeared so all roups of pigs gained at a sim- ar rate. In the case of barf iws the slower gain may be an dvantage as it allows for bet- carcasses. For this reason parate finishing of the sexes recommended with feed re- riction of barrows and full- eding of gilts. However, lim- ed energy intake may elimin- e real differences that exist tween breeding groups. in grain corn production is mainly due to the availability of earlier, high yielding hybrids. The Alberta Plant Industry Division's regional supervisor at Lethbridge, Ralph Trimmer, says that corn culture is no more difficult than that for any other row crops. Early planting (late April or first part of May) is very important and so is irri- gation, especially during the ;asseling and silking period of ;he crop. A plant population of approximately plants per acre is desirable. Some special equipment, including a corn header that can be attached to a regular combine, may be nec- essary for harvesting the corn which may also have to be dried. The Lethbridge Research Sta- ion is carrying out a fairly ex- ensive corn testing program, art of which entails selecting and classifying the hybrids ac- cording to.whether they mature very early, early, medium-late, etc. This classification allows a farmer to choose a hybrid that will suit his location and the purpose for which he is grow- ing the crop, i.e., grain or lage. The Alberta Corn Committee, composedof representatives' from the Lethbridge Research Station, the Alberta Department of Agriculture and the corn growers themselves, was form- ed last winter to co-ordinate the testing of hybrids and to make recommendations. The commit- tee evaluates all aspects of corn production and encourages and promotes com growing where 'easible. It has recently publish- ed a leaflet containing a "heat unit" map for southern Alber- :a and a list of hybrids suitable for the different regions. "Heat units" can now be calculated for any given area, and hybric are rated according to thei heat unit requirements. Mr. Trimmer says there ap pears to be a substantial potei tial market for grain corn i Western Canada. Although th most immediate markets ar distilleries and the feed Indus try, corn is also used for starch vegetable oil and food products At least one major grain firm is contracting for grain cor production this soring, and era! others are selling hybri field corn seed. A number o smaller private projects will in volve growing field corn in southern Alberta for tithe grain or silage. Corn when prop erly matured makes excellen silage. The "heat unit" leaflet and in formation on cultural practice: recommended for corn produc tion are available from distric agriculturists' offices.

Wooi carvers and cabinetm. a k e also took this method of "sign ing" their products. The practice of brandiri animals came to the Uniti States with Longhorn her from Mexico, where brandiri was already a 'tradition stock-owning Spaniards. Bran ing extended into Western Car ada from this Spanish traditio In keeping with1 the goner tastes of the Spaniards, earlie branding symbols were into cate. In early days, the imagin tion of branding-iron designe was given free reign. Som symbols were designed to d pict the stock owner's i dividual character or perso ality. Sometimes humor, fane and whim influenced design Due to the expense and difl cully of designing and ntaii taining the more intricat branding irons, designs gradu ally became more simple. Tlie most popular brant were derived from capital le ters of the alphabet, often combinations to make then unusual or different for eac man was striving for a branc of absolute originality and in dividuality.
