Última Glyphosate Mineralization: Effect of Temperature and Soybean and Corn Crop Residues Chilean J. Agric. Res. Rampoldi,Ariel; Hang,Susana; Barriuso,Enrique. Mineralization is the main mechanism of dissipation of glyphosate herbicide (N-[phosphonomethyl] glycine) in soil. However, there is scarce information about the mineralization process in strata formed by stubbles in no-tillage systems. The kinetics and rate of mineralization of herbicide in stubbles of soybean (Glycine max L. Merr.) and corn (Zea mays L.) were investigated. To evaluate the effect of age of crop residues, samples of soybean stubbles were collected immediately after harvest (Soja 1) and four months after harvest (Soja 2). Corn crop residues were collected three months after harvest. Glyphosate evolution and total microbial activity (TMA) were monitored by release of 14C-CO2 and C-CO2 under laboratory conditions with two temperatures, 15 and...
