Soil conservation and management
Soil conservation and management. Soil is the most important natural resource yet the most delicate. Mismanagement of soil will result into its impoverishment and erosion.
Soil improvement is a situation where soil is deprived its plant nutrients. Soil erosion is the removal of top soil by agents of soil erosion.
Soils may be conserved by:-
i. Afforestation and re-afforestation programs trees bind the soil and check the speed of rain as well as acting as wind breaks.
ii. Digging of cut offs and terraces which reduce the amount of slope of land. This encourages high infiltration of water by lengthening the duration of standing water on the surface.
iii. Good farm practices such as crop rotation, contour ploughing and planting mulching as well as use of fertilizers.
iv. Proper stocking which is keeping the number of animals required per grazing unit as well as establishing grazing patterns.
v. Laying of trash lines from the crop residues.
vi. Iive wash stops which are constructed by planting Sisal, grass e.t.c
vii. Building gabbions.
viii. Diverting some of the water, which cannot be contained by, terraces, gabbions or cut offs.
