Plant Rotation: Soil nutrients are depleted when the ground is occupied by a large number of the same type of plant. Florence J Martin

Large groups of the same crop make an easy target for pests. For this reason, non-organic commercial growers feel compelled to spray the whole area with pesticides. Soil nutrients are depleted when the ground is occupied by a large number of the same type of plant. This problem is compounded if the ground is used for the same crop next season - often the soil becomes so impoverished that artificial fertilizers are needed. And soil subjected to the same mechanical processes year after year will inevitably become compacted.
