Quizplus · Accepted Answer

Planting apples and leaving the land between the trees in grass rather than cultivating helps to minimize soil erosion in terrain with steep hill slopes. The grass cover helps to hold the soil in place and prevent it from being washed away by rainwater. Additionally, the trees themselves can also help to anchor the soil and protect it from erosion. Meanwhile, the wider spacing of rows (B), leaving the field idle (C), or straight rows and frequent cultivation (D) can all contribute to increased soil erosion in steep terrain.
