Micronized Soft Rock Phosphate, or MSR, is a non-metallic element that originates from the fossilized remains of the ancient organic life found around the world. Usually it is found in a rock form that is applied in large quantities to the soil which takes years to break down to plant available form even in ideal conditions. MSR is approved for organic use with many organic agencies throughout the US and Canada.

Phosphate is the workhorse of all minerals in the plant world. One important role that phosphate plays is to translocate or move the minerals into the plant. Phosphate is also responsible for improved seed germination, improved root growth development and is the synopsis for photosynthesis.

MSR is a product refined to less than 10 microns by a mechanical process which allows for immediate water solvency. As a water soluble product, it can be suspended in water and used in a sprayer for direct soil contact or for foliar applications. Smaller rates of application are very effective due to the efficiency created by the micronizing process.

Application rates will vary depending upon the nutrient level in your soil. When using this product for foliar application, caution should be used to ensure crop damage does not occur. Please consult a professional crop consultant for advice.

Do not apply with fungicides, herbicides and pesticides. Can be applied with GSR Calcium Turf Rite. Can be applied with most growth regulators and Cycle Works Turf Syrup and Turf Boost Molasses. Application rates vary depending on nutrients in soil. Use caution when using as a foliar application. Consult a professional consultant for advice.

Application Instructions
Application Rate Per Acre Frequency
All types of warm and cool season grasses Ground Spray 1-4 pounds per acre. Foliar 1-2 pounds per acre. Apply every 14-28 days
