__________ is a practice of growing strip of crops having poor potential for erosion control (e.g. root crop, cereals) alternated with strips of crops having good potentials for erosion control (fodder crops, grasses, close growing crops).
Answer: A
The practice is Strip cropping.
In strip cropping, long, narrow strips of erosion-permitting crops (row crops such as maize, sorghum or root crops) alternate with strips of erosion-resisting, close-growing crops (grasses, legumes, fodder crops) across the slope. The dense strips slow runoff, trap the soil washed from the open strips and help water soak in.
Regular and multiple cropping describe how many crops are grown in a year, not their arrangement for erosion control, so neither fits the definition.
