Energy Conservation In Corn Production, Wilbur W. Frye Dec 1982

Energy Conservation In Corn Production, Wilbur W. Frye

Soil Science News and Views

On-farm production of food and fiber uses about 3% of the annual U.S. energy consumption. About one-third of this energy is directly from fossil fuels used in farm tractors and trucks and for crop drying, while about one-fourth is used in manufacturing and transporting fertilizers. Tillage and N fertilizers are the two largest uses of energy in non-irrigated product ion of crops which are not dried artificially. Thus, the greatest effects of energy conservation can be achieved in these two areas.


Use Of Molybdenum For Soybean Production, Monroe Rasnake May 1982

Use Of Molybdenum For Soybean Production, Monroe Rasnake

Soil Science News and Views

Molybdenum (Mo) is a micronutrient that is required by soybeans in very small amounts. As little as 0.5 parts per million of Mo in soybean tissue is sufficient for normal growth. Compare this with a phosphorus sufficiency level of about 2,000 parts per million. However, even though only small amounts are needed, a Mo deficiency can drastically reduce yields of soybeans.
