Use these methods to ensure an effective cover crop that controls weeds and protects beneficial insects. FRUIT growers can improve their cover crop by inoculating their legume seed with rhizobial bacteria, thereby allowing an increased fix of nitrogen for a healthier drive row. Inoculating the seed increases the cost of planting a cover crop by 5% to 10%, but growers get a 20% increase in the amount of nitrogen added to the soil.
