Effect of Long-Term Plastic Film Mulching and Fertilization on Inorganic N Distribution and Organic N Mineralization in Brown Earth[J]. 2006, (6): 107-110.DOI:
This experiment was conducted on the loamy brown earth derived from loess-like parent materials at Shenyang Agricultural University during 1987~2003.The main results showed that the NO~-_3-N has been accumulated in the long-term plastic film mulching treatments.And the net N-mineralization rates in all covered treatments have increased.Also covering with plastic film can improve the content of NH~ _4-N and NO~-_3-N.In addition
the application of organic materials with inorganic fertilizers could improve the levels of net N-mineralization rates in soil.
