explain any four proper forming techniques which can be used for soil conservation
Answers
Ploughing along the strip lines instead of ploughing up and down avoids breakage of soil bonds and prevents erosion.
TERRACE FARMING
Cutting down steps or terraces in hilly slopes for cultivation decelerates the flow of water thereby preventing washing down of top soil.
PLANTING XEROPHYTES / SHELTER BELTS
Planting xerophytes and creating shelter belts helps to bind the soil together.
This method can be used in sandy regions and for stabilizing sand dunes in deserts.
STRIP CROPPING
Cultivating in strips of land by dividing a large field/plot into small strips and allowing grasses to grow between them.
This binds the soil together preventing erosion thereby conserving soil.

Answer:
The four technique are given below :
1)Contour planting
To avoid breaking soil bonds and prevent erosion, plow along the strip line instead of plowing.
2)Rice terrace farming
Cutting steps and terraces on hillsides for cultivation slows down the flow of water and prevents surface soil from being washed away.
3)Xerophyte planting / windbreak
Planting xerophytes and creating windbreaks help bind the soil.
This method can be used to stabilize sand dunes and desert dunes.
4)Strip farming
Cultivate by dividing the large land/plot into smaller belts and growing grass between them in the land belt.
It binds the soil, prevents erosion and protects the soil.
