Weeds cause crop loss indirectly by reducing the quantity of resources available for growth. Quantifying the effects of weed interference on nitrogen (N) supply, crop growth, and N nutrition may assi...
Previous studies have suggested grazing may alter nitrogen (N) cycling of grasslands by accelerating or decelerating soil net N mineralization. The important mechanisms controlling these fluxes remain...
The nature of soil type is an important factor in the bioaccumulation of substances in plants. Application of nitrogen fertilizer is a common practice in vegetable farming. This study was therefore co...
The inorganic nitrogen pool in soil, soil microbial biomass, nitrogen pool in vegetation and microbial nitrogen mineralization in soil were investigated to understand the effect of treatment for land ...
The Influence of nitrogen release from paddy soils on the grain yield of rice plants was investigated, and the optimum amount of nitrogen fertilizer application was estimated for each of the soil nitr...
Topsoils collected from various regions in Fukuoka Prefecture were incubated and the amount of mineralized nitrogen was measured. The relationship between the mineralized nitrogen amount (N) and the ...
It was investigated whether the amount of ammonification could be used as an index of soil analysis for fertilizer application, which was related with the amount of soil nitrogen supplied from paddy f...
The Illinois Soil Nitrogen Test (ISNT) was developed for this purpose, and involves estimation of gaseous ammonia liberated by heating the soil with strong alkali in a Mason jar. Several studies have ...
In pursuit of evaluating the suitability of methods for determining the ability of soils to supply available nitrogen under different soil conditions, two biological aerobic and anaerobic incubation ...
Effect of sowing methods on the productivity of catch crops and soil nitrogen leaching.
