Fertilizer General Rules of Thumb

hay rowFish Fertilizer: 3-4 gallons/acre, 3-4 times/year.
Humate for Trace Elements (most bang for your buck): 3-4 lbs/acre, 3-4 times/year to rebuild depleted soil and when trace elements return to average apply 1.5-3 lbs/acre/year depending on crop.
Nitrogen: Peas, beans, onions, garlic, and potatoes don’t need much nitrogen but grasses, corn, small grains, green vegetables need more.
Hayfield example: 4 gallons/acre, 3 times/year, application rates may vary based on stress by heat or lack of water. Generally apply the 3rd or 4th gallons after each cut.
