A glasshouse study was carried out to determine the isotopicdiscrimination (B values) and the isotopic fractionation factors (β)associated with symbiotic nitrogen fixation in stylo (Stylosantheshamata L.) and cowpea (Vigna unguiculata L.Walp). The B

Inhibition of the reduction of nitrous oxide (N2O) to dinitrogen (N2) by acetylene (C2H2) provides a method for measuring denitrification in the presence of atmospheric N2. Our objective was to measure N2O losses, using C2H2 inhibition, from 15N-labe

Biological denitrification was found to occur at depth, in the field, beneath a cultivated crop (black grain—Vigna mungo) and a permanent pasture (green panic—Panicwn maximum var Irichogtwne). A laboratory incubation study was conducted on intact

A simple analysis is described by which yields of grain sorghum, Sorghum bicolor L. Moench.), at different row spacings may be compared over a range of yield levels. Yield at one row spacing is plotted against yield at alternative row spacings. Then
