In the long term, such organic matter could accumulate in the form of macroaggregates, thereby further increasing soil C stock.
Since a further increase in soil erosion in the catchment is expected, vegetative and structural control measures are urgently needed to minimize the menace of soil erosion.
Greater vegetation coverage also leads to less surface runoff, which further increases surface soil moisture content and increases adsorption between soil particles and forms soil aggregates.
This implies, first, that the effects of compost only affect the soil surface, and second, the lack of carbonates in the siliceous quartzite contributes to further increases in soil hydrophobicity.
In line with basic studies in the 1960s (Beckwith and Reeve 1963, 1964; Jones and Handreck 1963; McKeague and Cline 1963 c ), lower soil pH would also have reduced adsorption of Si to clay particles, especially Fe and Al sesquioxides, further increasing Si in soil solution.
Maintaining optimum plant density as recommended for different age classes of rice could further increase grain yield while saving the valuable soil nutrients.
These results might be helpful for future monitoring of further increase of heavy metal concentrations in surface soils along highways.
Further, increase in dosage of RBI Grade 81 causing the soil to fail by brittle nature instead of plastic failure.
Coastal reclamation could significantly increase soil GHG (CO2, CH4, and N2O) emissions, further affecting global C cycle.
Acid precipitation can further increase the mobility of humic substances and trace metals in soils (Hallegraeff, 1993).
