1. Nitrogen Availability, Time of Release and Movement in Rotations Previous studies have found that N is released through the decomposition of sugarbeet tops (Moraghan and Smith, 1996: Reitmeier et a]., 1999). There is also evidence that N credits may be justified following other broadleaf crops, such as potato and sunflower. This evidence follows work by Vanotti and Bundy (1995) and Bundy et al. (1 993) suggesting that N credits from annual legumes are provided not by decomposition ofthe roots or release ofN directly into the soil from the roots as some might assume,... Download paper
2. Induced Manganese Deficiency in GM Soybeans Glyphosate resistance in soybean and corn reduced manganese uptake and physiological efficiency. Applicatior~ of glyphosate immobilized manganese applied before, concurrent with, or within 6-8 days after the glyphosatc event. Inorganic sources of manganese (Cl, CO,, SO,) tank-mixed with gly-phosate were antagonistic and reduced herbicidal efficacy: ho~vever, antagonism was significantly influenced by glypllosate fonnulation. Glyphosate root exudates and plant deconlposition products can alter the... Download paper
