Good Management Controls Pollution Danger Atrazine Proper management should eliminate potential pollution in using atrazine to control weeds in cornfields, according to Dr. Jon K. Hall and associates of the Agricultural Experiment Station at The Pennsylvania State University. ' The Penn Stats soil scientists recently completed 6 years of Take a four inside a Harvestore Harvesters is more than a storage structure It's a complete storage & feed processing system. This "inside tour" reveals a few features that make the Harvestore concept of crop management and preser vation a reality Top-loading, bottom-unloading The first feed into the structure is first out. Struc ture can be refilled as often is you wish without interrupting feeding. There is no abrupt change in ration. Gloss-fused-to-steel Over 51,000 lbs of steel and over 1,100 lbs. of glass go into a 25t0 Harvestore structure. The smooth, rugged interior/exterior finish is permanent and non permeable to air and water. Resistance to abrasives, acids, wind and weather is extremely high. Glass-fused-to-steel sheets overlap. Torqued bolts are tightened with pneumatic Wrenches. Joints and seams are sealed. Every structure is pres sure-tested for air leaks. experiments to determine possible losses of atrazine from a corn field with an average slope of 14 per cent. Atrazine was applied at the recommended rate' of 2 pounds per acre for surface application. In a season when rainfall was above normal, loss of atrazine from “washoff” averaged only 5 Mall to PENN-JERSEY HARVESTORE SYSTEMS INC. Maw Holland, Pa Ph.

The experimental site was planted in a manner to induce as much chemical loss as possible. The corn was planted up and down the slope instead of across the slope as recommended. The slope of 14 per cent was rather steep, giving a drop of 14 feet for every 100 feet. Even in a year with intense rainfall early in the season, loss from “washoff" was only 9 hundredths of a pound per acre. Dr. Hall claimed such losses would have to be considered minor due to the nature of the site and the soil and crop management practices used. It is obvious, Dr. Hall affirmed, that various chemical, biological, and non-biological forces in the soil and in the corn crop act to Regrade the original herbicide. soil core studies revealed that the atrazine was broken down in the soil at a moderate rate. Also, more than half of the chemical reacted with the topsoil and was held there. Measured one month after application, atrazine had dissipated to 39 per cent of the amount applied at the 2 pounds per acre rate of surface ap plication. Three months later the atrazine was down to 9 per cent of its original amount. Dr. Hall said the flood con ditions of 1972 created only slightly over 5 hundredths of a pound per acre “washoff” of atrazine. “Herbicide losses in the total studies were not as serious as losses of water and soil which were considerable at times. The results speak strongly for sound soil and crop management practices to combat erosional problems,” he affirmed. * rtdafettfr SatuVticlyl frflal973 Lean to Shop for Money Are you really as smart a shopper as you think you are? Sure you shop around in differ ent stores comparing prices and quality. And because you do, you can tell when a genuine bar gain is available and determine its value. But, the Pennsylvania Bankers Association asks, do you shop for money when you need it? That's right, shop for money. What is shopping for money? It’s another way of saying, do you compare interest and finance charges on loans or credit pur chases? You should, advises the Penn sylvania Bankers Association. There is a difference in rates you The slight loss of atrazine was reduced considerably more in 1972 by adding a broadcast planting of oats adjacent to the com at the bottom of the 14 per cent slope. This small block of oats further reduced chemical loss by 87 per cent. Furthermore, no atrazine toxicity symptoms were detected in the oats. In addition to atrazine, the studies included two ex perimental s-triazine herbicides. Losses for one of these ex perimental herbicides, related to atrazine, were equally slight. The Penn State soil scientists also examined the effects of an experimental s-triazine herbicide applied to alfalfa. Runoff water was very slight, no sediment was ever collected, and the con centration of herbicide was ex tremely small. HALES HUNTER CO. Franklin & High St I'd like to do a little exercise in math today. Let's assume ear corn costs $50.00 per ton, a 32% natural protein supplement costs $9.00 per hundred, molassas costs $4.00 per hundred and Cargill C. L. S. controlled release liquid sup plement costs $5.00 per hundred. If we want to make a fifteen per cent protein ration using the above ingredients, it would cost $98.50 as here itemized; 700 pounds of 32% sup. at $9.00-cwt 1100 pounds of corn at $2.50-cwt 200 pounds of molassas at $4.00-cwt $98.50 If you used Cargil C.L.S. it would cost $87.50 as itemized here; 500 pounds of 32% sup. at $9.00-cwt 1300 pounds of corn at $2.50-cwt 200 pounds of CIS at $5.00-cwt Of course you must add mixing costs to both examples, and prices on all ingredients will vary with time and location. Work it out with the figures you pay. And if your dealer can't you get'benefit of Cargill CIS, we can. KINDA MAKES A BODY WONDER, DON'T IT? ELMER M.

Maybe you never thought of that credit card as borrowed money, but that’s what it represents when you don’t pay your bills within the specified period of time, because the card issuer has paid for the merchandise. If you don’t pay him on time, he in effect charges you for the money you borrowed. Although there are state regu lations which set the maximum rate you can be charged for bor rowing money, not all banks and companies charge the maximum. Often you’ll find there’s a sig nificant difference in rates. And if you’re buying a big-ticket item, such as a new car, the difference in charges for borrowing money can amount to hundreds of dol lars over several years. So follow the advice of the Pennsylvania Bankers Associa tion. Learn to shop for money the next time you’re buying something on time. You’ll find it's a good way to make your money count! ihe Oldiumet /"T'N I “It’s a gre»t pity there isn’t a pesticide available for controlling the lilterbug.” Palmyra.
