Dynamics of Organic Nitrogen in acid and corresponding limed soil in relation to cropping and fertilization

Shree Prasad Vista, Nishan Bista and Dipankar Saha.


Abstract
Availability of nitrogen (N) to plants depends on the rate of mineralization of organic N in soil. Liming influences availability of N; and uptake of N by a growing plant in a particular time is not only controlled by the plant type itself but also by the microenvironment of rhizosphere which influences different N- transformation processes in soil. The present investigation was, therefore, conducted to make a relationship of changes in different forms of organic N in an alluvial acid and the corresponding limed soils with cropping and N fertilization. Results reveal that irrespective of soils, cropping and N-addition, in general, the amount of organic forms of N decreased with increase in the period of investigation. Furthermore, the amount of different forms including hydrolysable NH4+ and amino acid- N were maintained in higher amount in cropped over the uncropped system suggesting that presence of plant influences the micro-environment of rhizosphere soil. The congenial atmosphere created in rhizosphere soil in presence of maize leads to the release of higher amount of hydrolysable organic N in cropped situation. As the organic and inorganic form of N in soil are inter-convertible within themselves, the utilization of inorganic N by maize crop is replenished by different fractions of organic N released through mineralization and thus comparatively higher amount of different forms of N are accumulated in limed over the corresponding unlimed soil. But the amount of serine + threonine-N, unidentified N and non hydrolysable fraction of organic N did not show any definite trend of results.

Key words: Acid soil, Limed soil, inorganic N, Organic N.
