Going green...
My county extension office has recommended (based on a soil sample) a
15-0-15 for my St. Augustine lawn, and given me a list of organic soil amendments (bloodmeal, bonemeal, etc). How do I know how much of each to buy/ mix? Here’s what I’ve got: Amendment Affect on pH Major Nutrient supplied Bloodmeal Acid 12% Nitrogen Bonemeal Alkaline 22%Phosphorous Fishmeal Acid 10% Nitrogen Wood Ashes Alkaline 4-10% Potassium Peat Acid 1-3% Nitrogen Mushroom Compost Acid 2% Nitrogen Seaweed - 4 -10% Potassium Biosolids (Milorganite) - 5% Nitrogen My numbers: pH was 5.7 (target 6.5) phosphorus 15 ppm potassium 37 ppm magnesium 69 ppm calcium 675 ppm You may surmise (correctly) that I haven’t got a clue. Thanks in advance for any help!!!! |
