- ... Most cotton (Gossypium hirsutum L.) in the southeastern USA is grown on sandy soils that are subject to extensive N leaching. Split applications of N are normally utilized to reduce leaching losses. Even with split applications, however, leaching can still subject the crop to periods of N deficiency which can lead to yield reductions. Experiments were conducted at three sites (Typic and Plinthic P ...

- ... Potato plants are more sensitive to soil oxygen stress than many other common crops. Some recent literature suggests this may be due to a relatively high oxygen requirement for tuber growth, rather than a greater requirement for the roots per se. Consequently, the oxygen consumption of growing potato tubers (Solanum tuberosum cv. Russet Burbank) was measured in the field on a Portneuf silt loam (c ...
