Structural stability status as affected by long-term continuous maize and bluegrass sod treatments

摘要: ABSTRACT The effect of long-term continuous fertilized and unfertilized corn bluegrass crops on the structural stability status a clay loam soil was studied. Water-stable aggregates were measured with without an ethanol pretreatment before after extraction unbound lipids hydrophobic extracted chloroform. Compared to corn, sod wooded plots had three four times more stable associated dispersive dissolution action water two slaking forces. data also indicate that bound organic materials affected by cropping history rather than fertilization. Although varied significantly between treatments, responsible for similar amount when compared against results mono- dieste...
