Fertilizer ApplicationFertilizer Application

Nitrogen and Sulfur are key elements for Nitrogen and Sulfur are key elements for high yieldshigh yields

Nitrogen or potash shouldn’t be applied Nitrogen or potash shouldn’t be applied in direct contact with seeds but should be in direct contact with seeds but should be applied in a band at least 2 inches away applied in a band at least 2 inches away from seedsfrom seeds
