An Estimate Of The Soil Fertility Status Of Graves And Todd Counties In Kentucky, Kenneth L. Wells, D. E. Peaslee, Marvin Davidson, William Green

Agronomy Notes

Some concern has developed during recent years that fertilizer is being used by farmers on fields with residual levels of P and K high enough that such use is not justified as a means of increasing crop yields. This has been due to increased "average" soil test values for samples routinely submitted to college soil test laboratories.

For this reason, studies were conducted in Graves and Todd Counties in Kentucky during the period September, 1978 to September, 1980, to determine if soil samples routinely submitted to college test laboratories do or do not accurately reflect the average soil fertility status …

Soil Response To Clearcutting And Site Preparation In East Texas, J. J. Stransky, L. K. Halls, Kenneth G. Watterston

Faculty Publications

On an east Texas forest site, clearcutting and site preparation did not change the soil pH. Chopping and KG blading significantly reduced organic matter in the surface soil, while burning slightly increased it. Organic matter showed a positive and significant relationship to potassium, calcium and magnesium. All site treatments increased phosphorus and potassium, with the greatest increase on the burned plots. Calcium and magnesium contents also increased with burning but decreased with KG blading. Burning appeared better than the other treatments for maintaining or improving the soil nutrient regime. However, planted loblolly pine seedlings survived and grew best with mechanical …

G83-659 Irrigating Onions, C. Dean Yonts, David Nuland, Paul Fischbach

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide outlines the onion's water requirements as it develops through the season and how to best meet them to assure marketable grade and optimum yield.

Growing an irrigationd crop of onions is a very involved process. This is because the onion is a shallow rooted biennial that depends on daylength and temperature for the development of the marketable product—the bulb.

G83-652 Seeding And Renovating Alfalfa, Bruce Anderson, James T. Nichols

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses alfalfa production, including site selection and preparation, fertilization, variety selection, seeding, companion crops, stand management, weed control and stand renovation.

Alfalfa can produce more protein per acre than any other crop in Nebraska. Up to 100 percent of the protein needs of most livestock can be supplied by alfalfa in addition to large amounts of vitamins, minerals, and energy.
