“…Contrast analysis showed that it increased significantly (P < 0.05) when composted chicken manure (31%), chicken 'Dynamic Lifter' (24%) and the vermicast1 (25%) and vermicast2 (37%) were added to soil, but decreased (33%) with the application of biosolids. These results agree with the findings of Sonnleitner et al (2003) and Singh et al (2009) who also found an increase in dry-sieved MWD with the addition of various organic amendments, both solid and liquid. However, the increase in MWD due to the vermicasts might be a short-term effect because of the transient nature of the polysaccharide bonds which may have come from the liquefied amendment.…”

Short-term effects of organic amendments on properties of a Vertisol

Application of organic waste products as amendments has been proposed as a management option whereby soil quality of Vertisols could be improved. An incubation experiment was, therefore, conducted for 4 weeks under controlled temperature conditions (30 degrees C) to identify those potential organic amendments that might improve the quality of a Vertisol. Twelve organic amendments were investigated: cotton gin trash from three sources, cattle manure from two sources, green waste compost, chicken manure from three sources including a commercial product, biosolids and two commercial liquefied vermicomposts. Except for the biosolids, no other organic amendments had any effect on soil microbial biomass and respiration. Compared with NO3-N levels in the control, there was a 50% decrease in soil amended with 10 t ha(-1) green waste compost (65 microg g(-1)). The three different types of chicken manures increased the NO3-N concentration from 75% (228 microg g(-1)) to 226% (424 microg g(- 1)) over the control. Approximate recovery of P added by the amendment as resin-extractable soil P was 53% for cattle manure and 39% for chicken manure. Application of cattle manure resulted in a 22% increase in soil-exchangeable K over levels found in control. Organic amendments application also resulted in a significant increase in exchangeable Na concentration. Some of the organic wastes, viz. cotton gin trash (10 t ha(-1)), cattle manure (10 t ha(-1)), biosolids (10 t ha(-1)) and composted chicken manure (3 t ha(-1)) have value as a source of nutrients to soil and hence showed potential to improve Vertisol properties.

“…Dinel et al [119] claimed that the direct addition of lipid compounds to the soil encouraged the formation of polycationic bridges that bind the lipids to soil particles that enhance soil aggregation. Sonnleitner et al [120], meanwhile, reported that less than 0.5% of lipid was sufficient for the formation of unwettable aggregates in sandy soils. Soil permeability was reduced in these cases hence affecting its future use in agriculture.…”

“…For example, straw was classified as having fast and transient, intermediate, and recalcitrant agents (Martin and Waksman, 1940;McCalla, 1945;Sonnleitner et al, 2003). The humic substances in the soil were also found in multiple groups (Fortun et al, 1989).…”
