Results Of Nitrogen Applications On Ohio River Overflow Bottom Areas In Henderson County In 1967, Harold F. Miller

Agronomy Notes

In cooperation with Stuart Brabant, Area Extension Agent in Henderson county , four field trials with nitrogen fertilization on corn were conducted in the Ohio River Bottom area. In two of the trials where corn was followed by corn, nitrogen was applied at the rates of 0, 50, 100, 150 and 200 pounds per acre, with each treatment replicated 4 times. In the two other trials, where corn was grown following soybeans, nitrogen rates of 0, 100 and 200 pounds per acre were replicated 4 times in one field and 3 times in the other.

Planting was delayed until early …

Strongly Acid Soil Must Be Limed For Corn, Harold Miller

Agronomy Notes

The necessity of liming strongly acid soils that will be planted in corn is well illustrated in a demonstration conducted by Harold Vaught, Area Extension Agent in Adair County.

A field that was well fertilized with nitrogen, phosphorus, and potassium produced low corn yields in 1966. Analysis of a soil sample from the field showed that it was strongly acid soil. (Similar conditions have been reported by many farmers throughout the state in recent years.) Since this field was to be planted in corn again in 1967, a liming demonstration was planned .

Nitrogen Loss From Surface Application, Harold F. Miller

Agronomy Notes

Research work has shown that considerable nitrogen can be lost from surface applied ammonia-containing fertilizers. The nitrogen is lost due to the formation of ammonia which escapes into the air. Soil and weather conditions encouraging this loss are high temperature, moist soils, high pH and source of nitrogen.

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.

Changes In Soil Ph Caused By Heavy Nitrogen Fertilization, W. O. Atkinson

Agronomy Notes

Ammonium nitrate, ammonium phosphate, ammonium sulfate, urea and anhydrous ammonia leave acid residues, thus tending to make the soils more acid. The degree to which soil pH may be affected and the persistence of such changes for a silt loam soil is shown in the table below. The same amounts of phosphorus and potash were applied to all plots, and the different amounts of nitrogen were supplied from ammonium nitrate. Burley tobacco was the crop grown and the data are for 1963, which was the second consecutive year for the fertilizer treatments. (These were experimental plots and the high treatments …

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.

Symptoms And Control Of Zinc Deficiency In Corn, F. V. Pumphrey, F. E. Koehler

Nebraska Agricultural Experiment Station: Historical Circulars

The purpose of this publication is to describe zinc deficiency symptoms in corn and to present recommendations for applications of zinc fertilizer.

Root Yields, Sucrose, And Glutamic Acid Content Of Sugar Beets As Influenced By Soil Moisture, Nitrogen Fertilization, Variety, And Harvest Date, Donald G. Woolley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The United States produces about 1.8 million tons of sugar annually. Approximately 75 per cent of this production is derived from sugar beets. The importance of the sugar beet crop in national and world economy is justification for research effort as a means to more economical production.

It is desirable that sugar beet processing be carried out in the most efficient manner. More effective utilization of the sugar beet and its by-products will add stability to the sugar beet industry.

For the past 170 years, since Achard found that sugar could be used for human consumption and that pulp might …

Answers To Questions About Partridge Pea, T. H. Goodding, J. C. Russel

Nebraska Agricultural Experiment Station: Historical Circulars

The Nebraska Agricultural Experiment Station has been working with partridge pea since 1944. Seed has been distributed for tests, and several farmers are now growing it. It is primarily a plant for soil conservation and soil improvement. Its value in comparison with other legumes have not been fully established.

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.

Microorganisms And Their Effects On Crops And Soils, T. M. Mccalla, T. H. Goodding

Nebraska Agricultural Experiment Station: Historical Circulars

Many of the cropping and tillage practices that a farmer uses are effective in crop productivity because of their influence on microbial activity.

Bulletin No. 109 - The Nitrogen And Humus Problem In Dry-Land Farming, Robert Stewart

UAES Bulletins

The effect of cultivation and the growth of crops upon the nitrogen and humus content of soils has been studied by various investigators, both in America and Europe. In general, the results of the various investigations indicate that cropping and cultivation are very destructive of the organic. matter and the nitrogen of the surface soil.
