Microbial carbon and nitrogen limitations with mulching of proso millet fields on the Loess Plateau:evidence from soil ecoenzymatic stoichiometry

[Objective]Mulching measures can regulate soil properties;however,the effects on metabolic limitations are poorly understood,especially on the Loess Plateau.[Method]We conducted field experiments to compare three techniques:flat planting with no mulching(TP),ridge-furrow mulching system(RF),and plastic film mulching(PFM).Soil extracellular enzymatic stoichiometry and physicochemical properties of three growth periods(jointing,flowering,and maturity)of proso …查看全部>>
