Ammonia released on Treating Soils with N Sodium Hydroxide as a Possible Means of predicting the Nitrogen-supplying Power of Soils


THE only reliable method at present available for estimating the potential nitrogen-supplying power to crops of the organic nitrogenous fraction of soils is the incubation procedure. In this, soils are incubated under optimum conditions of moisture and temperature for periods of two weeks or longer and the quantity of nitrogen mineralized taken as a measure… (More)
