Agricultural Limestone In Kentucky, George D. Corder

Agronomy Notes

Kentucky farmers invested about $6 million in agricultural limestone in 1964. However, much more lime than this should have been used if farmers get the most economical crop production and the most efficient use of fertilizers that are applied or the fertility that is already in the soil.

Soil Surveys In Kentucky, Harry Hudson Bailey

Agronomy Notes

Twenty-two Kentucky counties have been surveyed and published using the classification scheme of the U.S. Department of Agriculture. These counties and the dates of the field survey are: Adair (1961), Bath (1959), Calloway (1937), Christian (1912), Clark (1961), Fayette (1931), Fulton (1961), Garrard (1921), Graves (1941), Jessamine (1915), Logan (1919), McCracken (1905), Madison (1905), Marshall (1938), Mason (1903), Mercer (1930), Muhlenberg (1920), Rockcastle (1910), Scott (1903), Shelby (1916), Union (1902), Warren (1904). The maps and reports on Adair, Bath, Calloway, Clark, Fulton, Graves, Logan, Marshall and Mercer Counties are still available (1965) through: Agronomy Department, University of Kentucky, Lexington.

Different Soils Need Different Amounts Of Limestone, George D. Corder

Agronomy Notes

Two different soil types may show the same acidity levels by soil test but they may need different amounts of limestone to obtain the same reduction in soil acidity.

Practices To Increase Grass Seed Yields Ky. 31 Fescue, Orchardgrass And Ky. Bluegrass, Robert C. Buckner, Paul B. Burrus Jr.

Agronomy Notes

Grass seed is a specialized crop in Kentucky. High per acre seed yields can be obtained by using the following suggestions that are made from research findings by the University of Kentucky Agronomy Department.

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.

Farm Manures, George D. Corder

Agronomy Notes

More than 16 million tons of farm manures valued at more than $47 million are produced on Kentucky farms each year.

Almost half of these manures accumulate in barns, feedlots, and loafing areas. A large part of this will accumulate in these areas between now and pasture time next spring. These manures must be removed from time to time and the cost of handling is unavoidable. Preserving their value and using them wisely on crops and soils that benefit from them will give a fair return on handling costs.

Agronomy Notes, No. 19, George D. Corder

Agronomy Notes

A Test Ban Treaty designed to stop nuclear explosions above ground was signed. World tension was eased. Fear of radioactive fallout was lessened. The Chinese have the atomic bomb. They did not sign the Test Ban Treaty. World tension is on the up-swing.

What has all this to do with agriculture in Kentucky?

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.

Calcium Deficiency Symptoms In Burley Tobacco, Jones H. Smiley, Ira E. Massie, George Everette

Agronomy Notes

Calcium is an element required by all higher plants in relatively large quantities. It appears to be closely related to the formation of buds and flowers.

Calcium is usually available in sufficient quantities in Kentucky soils to produce a normal crop of tobacco. However, when certain varieties of burley tobacco commence to bloom and produce suckers, the tips of the calyx lobes of the flowers may turn brown and die and the edges of the small leaves of the suckers may be necrotic, resulting in irregularly shaped sucker leaves. In severe cases the apical bud may be killed. These calcium …
