Water Penetration and Holding Capacity for Rice

Water penetration and holding capacity are dependent on soil structure including aggregate stability which allows for water to enter the soil and for the pores of the soil to retain that water.

Soil structure is especially important for rice production where the soil’s ability to retain water and oxygen levels that are required for optimal productivity.

The four-species consortium of symbiotic, arbuscular mycorrhizal fungi (AMF) in MycoApply® aids the columnal (vertical) formation of the soil structure which allows water to penetrate deeper into the soil profile, as well as promoting pore development that helps retain water until it is absorbed by the plant. In a poorly structured soil, the soil’s platelets lay horizontal instead of vertical which results in the development of hard pans which prevent water to penetrate beyond the hard pan. A hard pan from poor soil structure inhibits water and root penetration required for access to nutrients, water and oxygen required for rice to be productive.
