The "Energy-Pak” “Oxygen Controlled” Storage System includes a solid, steel reinforced concrete wall with a tough epoxy coating on the inside wall and a cone shaped concrete roof All access openings to the Silage Storage area are round and fitted with air-tight gaskets These round openings are easily clamped tight These features help to control and limit the amount of oxygen that comes in contact with the feed In operating an “Energy-Pak”, prime importance is placed on closing the silo after each filling and feeding operation Proper use of this system significantly reduces the oxygen content in the silo and results in a more ideal condition for maintaining the quality of the feed put into it ■■■■■■■■■■■■■■a Detach and mail to: WEAVER STAR SILO, CO.

LIDS Engineered for Convenience And Dependability LANCASTER - No-till and minimum tillage practices have introduced a major soil acidity problem not en countered under con ventional tillage; the creation of an “acid roof”. The concentration of acidity is in the top one to three inches of soil, Dr. W. Wayne Hinish, Penn State Ex tension agronomist, reported here earlier this month at the sixth annual No-Till Conference. This, he says, is the result of the acidifying effect of nitrogen fertilizers. Nitrogen when applied to the soil in the ammonium or organic form is changed to the nitrate form by bacterial action. During this process, hydrogen ions, which are acidity, are released. Under conventional tillage systems this acidity is mixed throughout the soil. This reaction has been known for many years, and it has been common to recommend about 5 pounds of limestone for each pound of nitrogen applied just to neutralize the acidity created by the nitrogen. The high build-up of P and Lancaster Farming, Saturday, January 27,1979 K in the surface area is not all bad. Under no-till and minimum tillage there is a greater concentration of roots near the surface than under conventional tillage. This is undoubtedly due to the better moisture condition near the surface,” Dr. Hinish adds. However, some adverse conditions may result of the build-up of P and K near the surface. There are in dications that high P levels can inhibit the uptake of zinc; high K levels can inhibit the uptake of Mg. What other in terrelationships may occur are yet to be uncovered. Results of two studies at Penn State clearly indicate that despite differences in yearly, absolute levels of water, soil and herbicide losses which are controlled by the amount, frequency and intensity or rainfall each year, the no-till systems are tremendously effective in reducing external drainage and downslope movement of apphed herbicides, reports Dr. Jon K. Hall, Penn State agronomist. Fnpn the standpoint of acidity yield, the use of birdsfoot trefoil as a “living mulch” for NT-com looks promising since it is less competitive than crownvetch on a comparative treatment basis. Moreover, singular applications of a residual triazine herbicide, such as cyanazine, are more ef fective in suppressing its initial growth than that of crownvetch. “In this same context, it would seem logical that using a spray mixture containing more than one triazine herbicide, which vary widely in their solubility, soil persistence and leaf absorption poten tial, would provide the op timum conditions sought with the “living mulch,” he notes. Future work should be designed to examine in total the herbicide combinations and rates, the optimum soil fertility conditions for the cover and crop and the soil and crop management practices consistent with achieving these ideal con ditions, Dr. Hall emphasizes. Reasons for the ac ceptance of the no-till method of establishing forage seedings were outlined by Melvin A. Brown, Centre County Extension agent. These include: -Reduced soil erosion on sloping land. -Reduced labor required - less trips across the field and less stones to pick. -Energy conservation - both in the form of reduced fuel consumption on the farm and (in the case of the introduction of legumes) less nitrogen fertilizers used. -Increased quantity and improved quality of forages realized due to the in troduction of legumes. -Easier for part-time or small farmers to make forage seedings without, owning a large inventory of equipment. In Centre County this type of farmer can hire custom operators to do all of the various jobs involved. -The gradual develop ment and increased availability of specialized seeding equipment. -The effect of the rapid acceptance of no-till com production in the county - the concept of no-till com and forage production is similar. This method also presents several disadvantages, he points out.
