Carbohydrates and aggregation in lowland soils of Nigeria as influenced by organic inputs

Effects of long-term tillage systems on aggregate-associated organic carbon in the eastern Mediterranean region of Turkey

“…SOC is the major cementing factor in aggregate formation in soil and moreover, according to most researchers, is significantly correlated with aggregate stability. (Spaccini et al, 2004;Tejada and Gonzales, 2006). Above explained results relation to effects of tillage systems on soil structure were significantly similar to results in other studies.…”

Effects of long-term organic and mineral fertilizers on bulk density and penetration resistance in semi-arid Mediterranean soil conditions

“…The decline in organic matter content of soils in control plots lead to the disintegration of aggregates demonstrated on significantly lower MWD values obtained in 2008 (Table 4). Spaccini et al (2004) also reported that organic matter integrates mineral particles of soils, and contributes to the stability of soil aggregates. Manure with mineral fertilizer application yielded greater aggregate stability as compared to mineral fertilizer applications alone (Hati et al, 2006).…”

The impact of organic amendments on soil hydrology, structure and microbial respiration in semiarid lands

“…Organic matter associated with the soil clay minerals may explain the significant influence of organic amendments on the percentage of water stable aggregates (Ferreras et al, 2006;Mainuri and Owino, 2013). A higher cohesion due to the binding forces between mineral particles and organic components can decrease the breakdown of aggregates Spaccini et al, 2004;Ojeda et al, 2008). Also, the improved structural stability can be attributed to the rate of organic amendments added to the soils (Bronick and Lal, 2005;Mainuri and Owino, 2013), as a significant increase in the percentage of water stable aggregates compared to the control treatment was observed at the higher application rate (30 Mg ha −1 ) of amendments (Fig.…”
