If you have an account set up with the lab, include the firm and outlet number and we will bill you at the end of the month. Several soil and weather variables affect the release of soil nitrogen and what happens to the nitrogen in the soil following release. Two common potassium fertilizer sources are available: potassium chloride (0-0-60) and potassium sulfate (0-0-50). For example, if the soil test reports a need to apply two pounds P2O5 per 1,000 square feet, then 4.4 pounds of 0-45-0 would be required per 1,000 square feet. If possible, agitate the liquids before collecting the sample. When an existing lawn or garden already has poor soil, the topsoil typically needs to be replaced. Periodic soil testing will help to correct nutrient deficiencies, avoid excess fertilizer applications and maintain a healthy lawn. Table 1Phosphorus fertilizer recommendations for all Missouri lawns based on soil test results. For the 13-13-13, each time you apply one pound of nitrogen per 1,000 square feet, you are also applying one pound of P2O5.
