Diatomaceous earth DE is a powder that coats the grid inside a pool pump. Although DE powder is used for filter grids, it can be added to sand filters. When the powder is added to the sand, the sharp edges of the DE powder enhance the filtering process of the sand by capturing tiny dirt particles during the filtering process.Chat Online

Thus, when lnc is applied the sand turns into a spongelike fabric that retains moisturewater and thereby holds the nutrients in the soil much better. consequently you need less water for irrigation, and the crop gets more nutrients and grows better yield. the mychorrizal fungi vital for any plant thrives and grows in lnc treated sand.
