摘要: ABSTRACTUnder the intensive agricultural system, direct application of animal slurries to soils can provide a sustainable disposal these wastes by inducing positive changes in soil quality and fertility. However, how quantitatively affect key nutrients (C, N, P S) transforming enzymes is not clearly known. A greenhouse spinach cultivation study demonstrated that pig slurry, either raw (RS) or processed (aerobically aged) (PS) form, significantly (p .05) alter aryl sulphatase enzyme activity. Slurry applications also improved macro (N, K) micronutrients (Cu, Mn, Zn Fe) uptake plant hence yield (2.9–3.38 times higher than control). Similarly, compared che...
