Topic is measures of soil conservation. Lesson is sand soil water natural vegetation and wildlife resources
Solution:
a. The method in which broad flat steps or terraces are made on the steep slopes so that flat surfaces are available to grow crops is called terrace farming.It reduces the speed of running water along slopes and allow water to drip down into the soil to prevent soil erosion.
b. The method in which the bare ground between plants is covered with layers of organic matter like straw is called mulching. It retains sil moisture.
c.. The method in which trenches are made in front of the barriers to collect water is called contour barriers.
d.. The method in which rocks are piled up to slow down the flow of water is called rock dam.
e. The method in which different crops are grown in alternate rows and are sown in different time to prevent soil from rain wash is called intercropping.
f. The method in which rows of trees are planted to check the wind movement to protect soil cover is called shelter belts.
g. The method of ploughing in which fields are made parallel to contours of a hill slope to form a natural barrier for water to flow down the slope is called contour ploughing.
