Define following terms: 1) strip cropping2) Bunding 3) fallow fields 4) plugging of gullies PLZ IT'S URGENT !!!!

Dear student, 
Please find below the solution to the asked query        

1. The term strip cropping  refers to a method of farming to accumulate moisture in these dry areas, cropland is periodically left fallow. Typically, the fallow and planted areas are organized in parallel long, narrow strips that are oriented normal to the prevailing winds, in order to minimize the erosion of soil from the bare fields. Strip farming helps to prevent mass erosion by having the roots of crops hold onto the soil to prevent it from being washed away.

2. Bunding, also called a bund  wall, is a constructed retaining wall designed to prevent flooding or rise and break through the surface of the water from a known source. It is a secondary containment system commonly used to protect environments from spills where chemicals are stored.
