Ansh Meshram from Fr agnel School, New Delhi
Subject :NSO    Class : Class 8

The semi-arid plains of a particular region show a pattern of alternating yellow and black stripes on the ground. The yellow stripes consist of land covered by ripening wheat. The black stripes are bare soil on which no crop is grown but farmers use herbicides or tillage to remove any weeds that try to grow in that region.
Why do farmers in this region manage soils in this way?

A Farmers put the half of their land to rest for minimising erosion and soil degradation.
B Farmers discourage transpiration in the wheat plantation by allowing free evaporation from the soil of the bare stripes.
C Farmers try to store some part of one year’s rainwater in the soil under the bare stripes and use that water to supplement the rain on wheat crop planted the next year.
D All of these
