A naturally-occurring iron-potassium silicate (also known as glauconite) with the consistency of sand but 10 times the moisture absorption.

How it works
For most part unexplainable. However, numerous trials show product is effective. One possible explanation is mineralization, which improves soil life by increasing populations of certain bacteria that slowly dissolve insoluble mineral nutrients.

General usage
An exceptional soil conditioner for pastures, forage fields, lawns, orchards, small fruits, vegetables, and greenhouse potting mixes.

Directions for use
As a soil conditioner, apply at 25 lbs per 1,000 sq.ft. To correct potassium deficiency, use soil test to determine rates and apply 20-100 lbs per 1,000 sq.ft., depending on extent of deficiency.
