Summary
Effect of hedgerow farming to soil conservation in terms of soil-plant relationship
Result of 7 years of soil conservation practice by hedgerow with tea, tea/tephrosia or tephrosia only and returning green material and crop residues to soil reduced run off and soil loss of 50% in comparison with no hedgerow. Soil fertility is also improved. But the quality of cation exchange capacity remains still very low and soil is very poor in calcium and magnesium. This may affect the nutrient status of food crop like that of maize for example.
