Sulfur Fertilizers For Alfalfa Production In Nebraska, R. L. Fox, A. D. Flowerday, F. W. Hosterman, H. F. Rhoades, R. A. Olson Jan 1964

Sulfur Fertilizers For Alfalfa Production In Nebraska, R. L. Fox, A. D. Flowerday, F. W. Hosterman, H. F. Rhoades, R. A. Olson

Nebraska Agricultural Experiment Station: Historical Research Bulletins

In order to elaborate all aspects of the sulfur problem in alfalfa production, a series of field, greenhouse and laboratory experiments was initiated to determine: 1. The influence of sulfur fertilization on the yield of alfalfa in Nebraska. 2. The influence of sulfur fertilization on the protein, vitamin A, and sulfur contents of alfalfa. 3. The sulfur supplying capacities of various soils under field and greenhouse conditions. 4. The sulfur content of precipitation at widely scattered points in Nebraska. 5. Soil properties associated with sulfur deficiency. 6. Optimum methods for estimating the sulfur status of soils by soil testing. The …


Phosphorus And Potassium Elemental Or Oxide, Harold F. Miller, George D. Corder Dec 1963

Phosphorus And Potassium Elemental Or Oxide, Harold F. Miller, George D. Corder

Agronomy Notes

Soil tests for phosphorus (P) and potassium (K) are reported on the elemental basis by all soil testing laboratories (state and county) in Kentucky.


Tobacco Stalk Production, Value And Use, George D. Corder, Harold F. Miller Oct 1963

Tobacco Stalk Production, Value And Use, George D. Corder, Harold F. Miller

Agronomy Notes

When Kentucky farmers finish stripping the 1963 tobacco crop they will have 176,000 tons of tobacco stalks worth $2 million on their farms.

These stalks will contain 9.8 million pounds of nitrogen, 932,000 pounds of phosphorus (2 million pounds of P2O5) and 13 million pounds of potassium (15.6 million pounds of K2O). Equal amounts of these plant nutrients bought in commercial fertilizers in 1963 would have cost more than $2 million.


Fertilization And Improvement Of Native Subirrigated Meadows In Nebraska, P. Ehlers, G. Viehmeyer, R. Ramig, E. M. Brouse Apr 1952

Fertilization And Improvement Of Native Subirrigated Meadows In Nebraska, P. Ehlers, G. Viehmeyer, R. Ramig, E. M. Brouse

Nebraska Agricultural Experiment Station: Historical Circulars

It is the purpose of this circular to summarize the 1948-51 results of fertilizer applications upon subirrigated native meadows. It is upon these lands that the cattleman depends to a large extent for winter feed.
