Preserve And Use Tobacco Stalks, George D. Corder

Agronomy Notes

When Kentucky's 1964 tobacco crop is stripped , there will be about 176,000 tons of stalks in and around stripping barns. There will be more than $2 million worth of nitrogen, phosphorus and potassium in them.

If these stalks are left outside the barn and exposed to winter rains, 61 percent of the nitrogen, 38 percent of the phosphorus, 83 percent of the potassium and 41 percent of the organic matter may be lost.

Organic Toxicity, Jones H. Smiley, Ira E. Massie

Agronomy Notes

In recent years there has been much discussion on the subject of organic matter toxicity and its relation to the severity of black root rot of tobacco. Organic matter toxicity is due to or at least related to toxins produced during organic matter decomposition.

Fertilizer-Insecticide Mixtures On Tobacco Plant Beds And Fields, George D. Corder, R. L. Miller

Agronomy Notes

Fertility and insect control programs have a major influence on tobacco production. The proper amounts and kinds of fertilizers and insecticides properly placed will make production more economical on beds and fields if either or both are needed.

Is a fertilizer-insecticide mix the best way to meet the fertility needs and t he insecticide needs on tobacco? The following questions and answers should help show how the decision was reached that this method is not recommended.
