Abstract:
... Among the seven problems we have mentioned as particularly affecting cotton production in the southeastern states, three lie in the field of agronomy. These are diversification and crop rotation, soil fertility, and the economic control of cotton pests. Experiment stations have accumulated a vast store of knowledge concerning soil fertility and perhaps the chief problem lies in taking it to the fa ...

... Lee has been the leading fall-sown oat in the northern Piedmont area for 25 years because of its hardiness, vigor, quality, and yielding ability. Numerous selections and crosses have been made to obtain varieties that would supplant Lee, which is susceptible to smut and the rusts, at the same time retaining the exceptional vigor of Lee. The most valuable Lee hybrids in this area have been Stanton ...

Abstract:
... Between 1970 and 1990, 85% of all new electric power generating capacity is estimated to require water for cooling. This poses a question for research scientists from several disciplines of finding some productive use for the waste water required by steam generating plants. Since there is usually a finite amount of water available for cooling purposes adjacent to the plant sites, the problem becom ...

None of the 12 samples of the 1969 crop collected in the south east contained aflatoxin but 14 of 22 samples of the 1970 crop in the same area contained aflatoxin. Corn from that area was infected with southern corn leaf blight in 1970. 4 of the 11 white corn samples contained aflatoxins a ...

Abstract:
... Sandy soils of the southeastern United States are often deficient in sulfur. The use of sulfate-containing fertilizers does not result in any buildup of sulfur in sandy soils since the sulfate is readily leached during whiter months. Interest, therefore, has developed in the use of elemental sulfur as a means of maintaining an adequate supply of sulfur where leaching is a problem. Studies were con ...

Many morphologically similar materials rich in iron oxides do not harden on repeated wetting and drying and are misidentified as plinthite. We propose that the following field-tested criteria be used to distinguish plinthite from similar materials that wil ...
