Dynamics of Nitrogen Derived from Organic Materials Applied to Paddy Fields as Estimated by a Direct Evaluation Method Using 15-Nitrogen

Publikováno v: 東北農業研究センター研究報告 = Bulletin of TOHOKU Agricultural Research Center. 112:1-40

In order to directly elucidate the dynamics of nitrogen (N) derived from organic materials applied to paddy fields, ^N-labeled organic materials were used in field experiments, and the ^N natural abundances (δ^N) of soils and organic materials in lo

Depletion of soil fertility and crop productivity in succession of paddy rice-soybean rotation

Publikováno v: 東北農業研究センター研究報告 = Bulletin of TOHOKU Agricultural Research Center. 103:39-52

To promote paddy-upland (irrigated paddy rice and upland crop) rotation farming, sustainability of crop production in the successive rotation system should be investigated from a long term view. The changes in soil nitrogen fertility, soybean product
