Sweet clover can grow nearly anywhere, with as little as 16 inches of rainfall per year. It has deep tap roots that mine soil nutrients and water from deep within the soil. It is better than many of the other clovers for nutrient recycling and appears to have a greater capacity to extract potassium, phosphorus and other soil nutrients from insoluble minerals. Sow in spring to summer at 1/2 lb./1,000 sq.ft. (15 lb./acre) as an annual, or let grow the next year over 6 ft. tall. Should be grown with 1½ to 2 bushels of oats as a "nurse" crop. Sweet clover is slow to establish the first year and may have some winter kill without adequate snow cover. Second year growth is tremendous. Will fix as much nitrogen as alfalfa and doesn't require an acid soil. Can produce as much as 170 lb. of nitrogen per acre although 100 lb. per acre is closer to the average. Excellent conditioner for poor and thin soils. Mostly yellow with some white flowers. Pre-inoculated with OMRI listed Nitragin Gold. USDA Certified Organic. Avg. 197,800 seeds/lb.
