Micronized Soft Rock Phosphate (MSR) 0-21-0msr-logo

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 breakdown 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 AgraForum for advice.

Phosphorous is the workhorse in the soil. All minerals other than Nitrogen should enter the plant in the phosphate form. In cooperation with Calcium, photosynthesis is increased and the production of sugar is greater.
Phosphorus is found in several forms in the soil, i.e.: P1, P2, and P204. P204 is the organic state that is stable in the soil and available to the plants. All other forms of phosphorous require metabolic changes before the plant is able to utilize it.
Characteristics of Phosphate include:
  • More vigorous and rapid growth.
  • Early root development.
  • Better development and quality of grain.
  • Hastened maturity.
  • Increased nitrogen uptake.
  • Increased mineral content.
  • Higher BRIX readings in plant sap.
  • Promotes energy release in cells, cell division, and enlargement, photosynthesis.
  • Contained in the cell DNA.”
