Nitrogen（N） is a key nutrient for rice production, and its bioavailability in paddy soils is strongly coupled to soil organic matter（SOM） cycling. A better understanding of potentially available N forms in soil, such as alkaline hydrolyzable N（AH-N）, and their depth distribution will support the development of best management practices to improve the N use efficiency of rice while minimizing adverse environmental effects. Fifteen rice（Oryza sativa L.） fields from Southern Brazil were selected, a...
