Nutrient budgets (N, P, K, Ca, and Mg) were developed for conventional-tillage, no-tillage, and old-field systems. Data for the budgets were collected over a 2-yr period, with grain sorghum as a main season crop followed by a cover crop of winter rye

A series of plots in an Amazonian Rain Forest were trenched and treated with calcium to determine the effects of perturbation on numbers and activity of nitrifying bacteria. Although treatment resulted in between 2 and 26% of the nitrogen being lost

A microtechnique based on the most-probable-number (MPN) method has been developed for the enumeration of the ammonium-oxidizing population in soil samples. An MPN table for a research design ([8 by 12] i.e., 12 dilutions, 8 replicates per dilution)
