This naturally occurring iron-potassium silicate (also called glauconite) has the consistency of sand but is able to absorb 10 times more moisture, making it an exceptional soil conditioner for pastures, forage fields, lawns, orchards, small fruits, vegetables and greenhouse potting mixes. Greensand contains potassium, iron, magnesium, calcium and phosphorus plus as many as 30 other trace minerals.
Greensand has the consistency of sand with a density of approximately 90# per cubic foot (very heavy). It flows like sand and can be applied through any type of spreader, seeder or drill. It can hold one-third its weight in water and has the ability to open tight soils and bind loose soils.Application RatesApplication rates vary depending on soil conditions and intended use. As a soil conditioner, applications of 25#/1000 ft2 (or 1000#/acre) are recommended. To correct potash deficient soils, anywhere from 20# to 100#/1000 ft2 (or 800# to 4000#/acre) would be applied, depending on the extent of the deficiency.
Greensand is available in 50 pound bags
Full pallets are 50 bags
Available in one to bulk sacks
NOTE: Greensand is a slow release insoluble source of potash and trace elements. If there is an immediate need for available potash, it is suggested that Greensand Plus (a combination of Greensand and Natural Sulfate of Potash with 17 percent soluble potash) or Natural Sulfate of Potash (contains 52 percent soluble potash) be used.
