Summary Of Fertilizer Use And Estimated Use Of Plant Nutrients On Tobacco, Corn, Hay And Pastures In Kentucky, Kenneth L. Wells
Summary Of Fertilizer Use And Estimated Use Of Plant Nutrients On Tobacco, Corn, Hay And Pastures In Kentucky, Kenneth L. Wells
Agronomy Notes
Nearly 650, 000 tons of fertilizer were used by Kentucky farmers during the first half of 1969. Plant food content (N+P2O5 + K2O) was 38%, or nearly 247,000 tons. Slightly over half (58%) was sold in bagged, one-third (33%) in bulk, and 8% in fluid form. Mixtures made up 70% of the total tonnage, and materials made up 30%. The statistics tabulated below show a more detailed breakdown of the fertilizer tonnage used.

Agronomy Notes
In trying to determine if it would pay Kentucky farmers to irrigate corn, one of the most important steps is to ascertain the long-time average yield increases to be expected from supplemental irrigation. The yield data reported below are the results of an experiment applicable for a fairly large group of soils occurring in Kentucky.
