Umeh (1989) explains that soil erosion can be controlled
through the following ways:
through the following ways:
i.
Contain – cropping : A good control
measure is to alternate row crops like maize or cassava with grasses and
legumes. Grasses and legumes resist erosion by giving adequate cover to the
land.
ii.
Terracing: This is the construction of terraces along
the steep slopes.

iii.
Vegetation cover: Water erosion can be checked by putting the
farm lands under vegetative cover. Uncultivated areas are covered by cover
crops and grasses. Vegetative cover is also good for checking wind erosion.

iv.
Wind breaks: These are trees planted
in rows to check the velocity of wind, this is practiced in area strongly
threatened by desert encroachment.

Crop residue: Crop residue left on surface of the land
prevents wind from carrying away soil particles.

According to Iwena
(2008) the control of soil erosion includes;
(2008) the control of soil erosion includes;
i.
Afforestation: It is planting of trees to control erosion
ii.
Re–afforestation: This is the replanting of trees in areas and
do not contain plants before in order to clack erosion.
iii.
Controlled ploughing: This is the
making of ridges across the slyer to control erosion.
iv.
Cover cropping: This is the planting of legumes to cause the
soil so as to prevent erosion.
v.
Terracing: This is the method of
cutting step on hills sides to reduce the speed of running water down the hill.
vi.
Shelter belts: This is the planting
of trees in form of belt where wind erosion is dominant so as to serve any wind
break and reduce wind erosion.
vii.
Enlightenment programme: People should be educated on the effects of
soil erosion and on soil conservation measured.
viii.
Legislation: These are laws made to contact erosion
through soil conservation boards.

ix.
Improved farming method: The practice of mixed farming, strip cropping
and crop rotation help to control erosion.
