Apply 500-1,000 lbs per acre depending on specific crop needs or required pounds of actual nitrogen per acre.
Vegetable Gardens & Flower Beds:
To prepare new gardens, apply 2.5-5 lbs per 100 square feet and thoroughly mix into the top 3″ of soil. For new transplants, add 1-2 tbsp per hole, mix into soil and water in well. To feed established plants, side dress 2-4 oz once each month during the growing season to promote fruiting and flowering.
Trees & Shrubs:
