Molybdenum Deficiency In The Wheatbelt, M M. Riley

Journal of the Department of Agriculture, Western Australia, Series 4

The trace element molybdenum is needed in very small amounts in nitrogen metabolisms of crops and pastures. One of the projects that started as a result of the overall soil acidity research programme was the examination of molybdenum deficiency on acid soils throughout the South-West of Western Australia.

Use Of Molybdenum In The Transplant Water For Burley Tobacco, J. L. Sims, Jones H. Smiley, M. E. Suchy, A. M. Wallace

Agronomy Notes

The need for adding molybdenum to tobacco arises because contents in Kentucky soils generally are on the "borderline" of sufficiency and because amounts of available molybdenum in soil are low when soil pH is low. Soil pH in tobacco fields at midseason often is 0.5 to 1.0 pH unit lower than prior to fertilization. primarily because of the high rates of commercial fertilizers commonly applied to tobacco. This acidity greatly lowers the availability of molybdenum to tobacco plants. That is why we recommend the use of molybdenum when soil pH before fertilization is 6.4 or below.

Molybdenum Recommendation For Legumes, J. L. Sims, Warren C. Thompson, S. H. Phillips

Agronomy Notes

Molybdenum is recommended in Kentucky for legumes (soybeans, alfalfa, clovers and other forage legumes) beginning in 1969. The application should be made as a seed treatment and at the rate of 0.4 to 0.8 (4/10 to 8/10) ounces of molybdenum per acre. Molybdenum is recommended only on soils testing less than pH 6.2.

Where Is Moly?, A. L. Hatfield

Agronomy Notes

Is moly in hiding or has it gone down the river? Recent tests in Graves County suggest that it is probably just in hiding.

Moly (molybdenum) is of importance to Kentucky farmers because of its unique relation to soil acidity and legume growth. Many other trace or minor elements necessary for plant growth are most available to crops under acid soil conditions. Molybdenum becomes more available as the soil acidity approaches neutrality.

Molybdenum Increases Cereal Yields On Wheatbelt Scrubplain, R J. Doyle, R. J. Parkin, J. A. C. Smith, J. W. Gartrell

Journal of the Department of Agriculture, Western Australia, Series 4

IN four field experiments and two paddock strip trials since 1960, molybdenum applied to wheat and oats grown on scrubplain soils in the eastern wheatbelt increased yields by up to 3 i bushels of wheat and 5^ bushels of oats per acre.
