The term 'TILL THE GROUND' can be solved by the four-letter word 'PLOW'. Plowing is a traditional agricultural technique used to prepare soil for planting. It involves using a PLOW, which is a tool with a blade or disc that is pulled through the soil to turn it over and break it up. This process helps to aerate the soil, remove weeds, and mix in organic matter. Plowing also helps to improve water drainage and increase fertility.
