Question

A system of rotating crops with legume or grass pasture to improve soil structure and fertility is called
A. Ley farming
B. Contour farming
C. Strip farming
D. Shifting agriculture

Answer 1

Hint: This farming of legumes and helps to improve the soil fertility in the crop alternation with the help of nitrogenous compounds to the soil and help to provide the appropriate amount of the minerals to the soil. It is involved in the grasses, legumes, and use in the various annual crops that help to grow in long term and short term managed soil nutrients.

Complete answer:
Ley farming is the growing of tilled crops and grass in the measurements of soil conservation. Improving the soil fertility for obtaining the higher yields of the arable crops and emphasis is the process that applied to the grass-legume mixture to get the fodder for livestock. With the help of the ley farming improvement of the nitrogenous content for the subsequent plantations and also increased the restoration of the soil and organic matter structure. With the help of this also improves the preventing deep draining and erosion of the soil or controlling the growth of the weeds that cattle eat the unwanted plants of the grazing pressure and this approach is effective for combating weeds annually.
-In the hilly areas within the falling of contour and slopes are known as the name of contour farming. Terraces are the kind of horizontal stripes obtained by the divided series. The soil conservation, indirectly mitigation of the flood control, production of the crop yield possible with the contour farming. -In the alternation of the crop rotation system, the cultivation of the field partitioned farming possible with the strip cropping. When no other prevention method was found for the soil reasoning that time strip cropping method used over them.
-For a few years in the ground of tropical Africa regions the cultivation and vegetation of the new areas naturally restored until it's fertilization state in the form of agriculture known as the type of shifting cultivation.
Therefore the correct option is (A).

Note: The investment of the lots of money and considerable time of the problems arise due to the improvement preparation of the seeds. And also have unfavorable weather conditions and low quality that remove all modern forms of plant cultivation from the soil. It is required to observe a certain interval before removing and sowing plants in order to ensure a good future harvest before sowing the new crops under the ley farming techniques.
