Lethbridge Herald, The (Newspaper) - October 30, 1970, Lethbridge, Alberta 10 THE LETHBRIDGB HEKALD Friday, October SO, 1970 UTHBRIDGf RESEARCH STATION Aroma., Insects And Wheat DR. R. HASTING, Biochemist We are familiar with the many aromas of flowering plants, and know each aroma is distinct and is produced by one or many volatile organic chemicals generated within the cells of the plant. In some countries these vola- tile chemicals are extracted and collected for very profitable perfume and flavor industries. In Sweden, scientists are help- ing their food industry by study- ing the chemistry of aroma for a large group of foods includ- ing frozen fish, berries, can- ned meats, and herbs. The Swe- dish scientists have developed highly sophisticated techniques for identifying and measuring these aroma producing chem- icals. We have applied the Swedish methods to the analysis of the green leaves of spring wheat. This has led to the discovery of a whole series of volatile chemicals whose presence in the wheat plant was previously Dot known. These naturally occurring chemicals may play a part in the development of new varie- ties that are resistant to in- sects. The aromas given off by some growing plants have strong attracting or repelling powers for certain insects. Fur- thermore, they are instrumen- al in promoting the feeding of insects on some plants. Recent- ly it is emphasized that, be- sides the flower, green leaves of many plants also produce vol- atile chemicals that give char- acteristic aromas. Now that some of the volatile chemicals in wheat leaves have been identified we can test them in the laboratory at the Leth- bridge Research Station. We shall determine their effects on the insects that destroy our crops on the prairies. By apply- ing such naturally occurring substances it may be possible to keep undesirable insects away from crop plants. Such novel and built in methods promise to reduce the cost of insect control in the future. In his way the use of insec- Mdes might be decreased and returns to the farmer increased. Maritime Farmer Develops Effective Memory Machine MIDDLETON, N.S. (CP) A memory machine for farmers is what Cyril Langiile of nearby Brooklyn calls his new livestock records machine. The livestock farmer's biggest headache is keeping track of a series of dates for a large num- ber of cattle in his herd. The dates he has to know in- clude breeding and gestation pe- riods and farrowing times in fact, everything about his live- stock that could mean the dif- ference between profit and loss. Mr. Langiile, a young farmer, enlisted the help of civil engi- neer Cleve Sinclair of Middle- ton, and together they came up with the Anna-Dial. The mac h i n e is basically a large calendar dial. It Iras a ro- tating calendar wheel 30 inches in diameter recessed into a flat console board. The dial can be calibrated against the console base for any type and condition of animal. The Anna-Dial, for which a patent has been applied, can handle up to 300 units of female cattle. They are represented by numbered tacks on the calendar wheel that correspond to the same number tack in their ear. Important times such as breeding and gestation periods are indicated at the perimeter of the wheel on the console. THE SUGAR BEET HARVEST is fast drawing to a close in southern Alberta, ai the itream of trucks hauling beets to receiving stations like this one near Chin slowly thins out. The harvest is about 95 per cent completed. There were acres of sugar beets grown in south- ern Alberta this year. Saline Soil May Be Reclaimed By Installation Of Tile Drains Installing tile drains in semi- arid soils appears to be the height of folly, yet scientists at the Lethbridge Research Sta- tion are demonstrating that tile drainage may be .an esential step in the reclamation of at least some semi-arid soils. The reclamation projects in- volve irrigation, but the coun- ter balancing act of subsur- face drainage is just as essen- tial as adding water in the first place, according to Dr. Theron Sommerfeldt, physical chemist at the station. This is because the underly- ing soil ta some dry regions con- tains a high level of salts which are slowly permeable to water, and when irrigation is applied, these salts move in solution to the upper levels of soil. If enough salts move to the upper layer of soil, Dr. Som- merfeldt says, it will become salinized (salted) and actual- ly inhibit crop growth. Some areas in the United States, first brought into lush production through irrigation, have since been seriously af- fected because of salt accumu- lation. The same problem applies to many areas of western Canada: irrigation could vastly improve production on these lands, but, in the long run, salt movement to the surface could be damag- ing unless precaution is taken. Dr. Sommerfeldt has now demonstrated that some of these saline lands can be reclaimed by'Installing drainage systems, then flushing the salts away through irrigation, and, in lands that have not yet been salimzed, a drainage system could carry excess water away before it dis- solves salts and brings them to the surface. Dr. Sommerfeldt used both four inch clay tiles and per- forated corrugated plastic tub- ing in his systems and 4-H News From Southern Alberta PICTURE BUTTE A reorganizatipnal meeting of the Lethbridge Northern 4-H Beef Club was held at the home of James Murray. The meeting was called to or- der by the president, Dick Haney. The pledge was led by Rod Murray. Officers elected were, presi- dent, Hod Murray; vice presi- dent, Pat F o s t e r; secretary, Carol Boras; treasurer, Shirley Bulva; club reporter, John Mur- ray. Weigh in for the calves will be held Nov. 11. It was decided that meetings will be held on the first Mon- day of every month at the Pic- ture Butte Library Building. Awards night will be Nov. 10. GREEN ACRES The Lethbridge Green Acres 4-H Dairy held its reorganizational meeting at the Capri last October 19. We had a poor turn out so it was decided that we would wait until next meeting before elect- ing officers. Our leader, Mr. Handsaeme, suggested that we might give some thought to amalgamating with another club. There was some discussion on this, and it was decided that we try to get some new members. If this fail- ed, then we could again discuss joining with another club. So come along you.future 4-H- ers join our club. It isn't a large club but what we lack in num- bers we make up hi enthusiasm. We have countless activities, such as a visit to the ice ca- pades, bowling and roller skat- ing parties along with our reg- ular club work. If you are at all interested, our next meeting is at the Civic Centre Novem- ber 2nd. Mary Ann MAGRATH A 4-H Beef Club was recently formed in the Magrath district. The new club has 18 mem- bers. The officres elected were Brent Dudley, president; Dan- ny Gruninger, vice president; Elberta Christensen, secretary; Cathy Schneyder, treasurer; Wayne Gruninger, historian and Ken Hfllmer, club reporter. The person selected to lead the club was Dan Gruninger with Arthur Wocknitz acting as assistant leader. The advisory committee con- sists of George Dudley, Reid Gruninger, Don Gruninger, Ken Miller, Heher Christensen and Norman Hillmer. Meetings will be held every second Wednesday of the month in the Magrath Lions Hall.

Ken MItK RIVER The reorganizational meeting of the Milk River 4-H Beef Club was held Oct. 15 at the Erie Rivers High School. Our leader, Robert Kuhl, pre- sided until the officers were elected. The officers are as fol- lows: president, Gordon Miller; vice president, Wayne Thie- len; secretary, Kathy Angyal; treasurer, George Stringam and club reporter, Ray Brown- lee. It was decided that this year our members could feed cross- bred calves but Herefords would be more desirable. Mem- bers must have their calf by Nov. 7, and the calf should be between 400 and 550 pounds. John Clarkson and Rich a r d Spence, both members of the International Agricultural Ex- change Association, showed slides and answered questions about their native New Zealand. The regular monthly meetings are to be held at the high the first Thursday of every month and are to begin at p.m. Ray PRONGHORN The reorganization of the club was held in the Foremost School Oct. 12. There were 10 members and then- parents present. The club decided that the grain section would be dropped due to lack of interest. A peewee section was formed with seven members. Election of officers was held with the following results: President, Paige Keuhn; vice- president, Garry Strain; secre- tary treasurer, Jodi Cowie; club reporter, Rick MacKenzie, club leader, Jack Cowie; assis- tant leader, Charles Hougen; di- rectors, rest of Ihe fathers. The club decided on mixed breeds and the weigh in is to be held at Hougen's corrals Oct. 31 at a.m. Meetings are to be held on the 3rd Monday of every month.

Recreation for the first half of the year Patricia Herbst and Sherry Black. Recreation for the second half of the year Roxanne Flexhaug and Evelyn Bryle- meer. Old business included a let- ter about our 4-H camp and our tour. New business was a 'discus- sion of fund raising ideas, our tour, and the county color night Nov. 10, and our local color night also in November. It was decided to hold the business meetings in the mem- bers homes and the sewing meetings in the Hoping Centre. This year we have 11 mem- bers and 2 prospective mem- bers. Our club leaders are Mrs. Marg Mitzel, Mrs. Doreen Lee, Mrs. Josephine Fauth, Mrs. Laura Wesley, Mrs. Emma Dix- on, Mrs. Lylla Herbst, and Mrs. Beverley Black. There will be a meeting of leaders and executive Oct. 19 at the home of Bev Black to plan the years programme. SHERRY BLACK reporter. found that both worked well. The drains were placed four feet deep and 82 feet apart, then 24 inches of irrigation wa- ter was applied last year. There Pregnancy Test Developed Dr. Hamish Robertson, a Canada Department of Agricul- ture scientist has developed a new pregnancy test which can be applied to a wide range of domesticated animals. The test will determine preg- nancy within three weeks of breeding; it is accurate and re- latively simple to perform. Dr. Robertson believes it will be extremely useful, particu- larly to researchers working with livestock and possibly to modern livestock farms. He will not, however, specu- late on its usefulness in deter- mining human pregnancy. "The same.method will work, and it could be particularly useful, for testing for. concep- tion in cases where ovulation has been induced in anovula- tory women, but I'll leave that up to the medical profession to he says. The test is based on measur- ing the concentration ''of the hormone .progesterone, in a small blood sample taken two to three weeks after the ani- mal is bred. Order Seed Now Southern Alberta farmers are advised to order their seed re- quirements for the newer Va- rieties of cereal grains and rapeseed as soon as possible. The Alberta plant industry's cereal and oilseed crops spe- cialist, Sherman Yelland, Ed- monton, reports that there is a shortage of Hercules durum wheat, Bonanza barley, Cougar and Frontier fall rye and of pedigreed stocks of the Polish- type rapeseed Arlo, Echo and Polar. Since large quantities of our present rapeseed varieties are going to be required for both ;he domestic crush and for ex- port in 1971 and 1972, it is im- portant, says Mr. Yelland, that seed requirements be arranged for before present limited stocks of pedigreed seed run out. He joints out that pedigreed seed costs very little extra per acre and that a small down payment will usually hold an order.

About 50 per cent of the Irri- gation water came out through the drainage flushing salt out of the soil. The greatest reduction of salts was in the top six inches of soil. In addition to salt removal through the drains, Dr. Som- merfeldt says it was evident that both salt and water leach- ed past the drainage system to lower soil levels. "From this study, it appears feasible to reclaim some sal- inized soils with shallow drain- age and he says. "But the water table will be near the .surface in this area, and, unless proper management is practised, we expect there will be resalinization." "By proper management, we mean management practices that retard salinization, and that the soil should be occa- sionally flushed of accumulated salts. "Our expert ments indicate that plastic. tubing is cheaper than clay tile in our area, it is easier to install and appears to perform equally well with clay tile. Other studies are In pro- gress to further evaluate the relative performance of vari' oils surface drain materials and he said. Imported Beef Poses Threat The Canadian Cattlemen's Association has recommended to H. A. Olson, federal minis- ter of agriculture, that beef imports from Australia and New Zealand he controlled at a level that will not prove in- jurious to our domestic beef in- dustry. In a meeting held rewfiUy in Calgary with Mr. Olson and Deputy .Minister Syd Williams the CCA executive pointed out that imports from these two countries had alarmingly in the last two years and had now reached levels that were threatening, and may already have affected, domestic prices. The cattlemen's spokesmen recommend that imports from all sources not be allowed to exceed 5 per cent of domestic consumption and that only those qualities of beef that are deficient in Canada be ap- proved for import. In advocating controls at rea- sonable levels, the CCA main- tains that this is in the best interest of both the importing and the exporting countries. With prior knowledge as to the amount of imports-that will be permitted, both the importing and the exporting country will Some Fat Necessary It is poor practice to overfin- ish meat animals, .says Dr. W. R. Usborunem Dept. of Ani- mal Science, University of Guelph. However, some fat on meat is desirable. A thin covering of fat on a carcass prevents shrinkage and protects the meat from contamination when it is handled. Fat also adds palata- bility. Research has shown that all meat completely devoid of fat tastes exactly the same: it is the fat that makes beef taste like beef. Chemical compounds in the lean meats and fat inter- act when meat is cooked to pro- duce the unique meat flavors. Fat protects meat from drying during cooking, since the moisture meat. Cooked fat also stimulates the salivary glands and thus en- hances the sensation of juici- be able to plan production on a rational basis. In the absence of such ments, neither country can plan production with assurance that the product will find a market. "If the Federal Govenunrot advocates free trade in intw- national markets and supply management in domestic pro- duction, it has. .contradictory policies that seem difficult to rationalize" says C. A. Gracey, manager of toe cattlemen's as- sociation. No Rush To Deliver Rapeseed Don't rush to deliver your rapeseed when the quota opens up again later this year, and keep a close check on: daily prices, advises David Walker, marketing economist with the Alberta department of agricul- ture. He points out that the ten- dency many farmers have taking their rapeseed into the elevator as soon as the quota opens causes an oyersupply for several weeks which, in turn, depresses prices. These fanners are inclined to receive a lower price than those who do not deliver their rapeseed until several weeks after the quota has opened. Once the initial flush of de- liveries has subsided, prices tend to improve, Mr. Walker says. Rapeseed prices, unlike those for wheat, barley and oati which are pooled, reflect cur- rent market prices and the day to day fluctuations in demand and supply. When an elevator receives a shipment of rape- seed it hedges, or sells, the rapeseed for future delivery on the The Winnipeg elevator grain market, company does this to protect itself from fluc- tuations in price which may occur between the time it buys the rapeseed from the farmer and the time it sells it to the exporter or domestic crusher.
