Rock Phosphate 0-4-0 by Espoma
Benefits of Rock Phosphate:
• Organic source of phosphorus & micronutrients
• Rock phosphate contains 32% total phosphate (P2O5). Phosphorus is an essential nutrient required by plants that is primarily responsible for healthy root development and fruit and flower production. In addition, rock phosphate is rich in minor elements such as boron, zinc, nickel and iodine which plants need in small amounts for optimum growth.
•
• Long term, slow-release feeding as the plant needs it
• Rock Phosphate becomes naturally available, as the plant needs it. Plant roots give off carbon dioxide and certain organic acids which react with the rock phosphate in the soil, making it available for plant use. Because Espoma® Rock Phosphate is ground to a fine powder, a sufficient part of it is immediately available to the plant because the particles are so tiny that the organic acids and carbon dioxide produced by the plant roots and bacteria in the soil can break them down quickly.
