摘要:
Disclosed are soil additives capable of hydrophilizing soil particles and/or increase available water capacity in soil. The soil additive are capable of increasing the available water content/capacity (AWC) in soils, the additive in one embodiment comprising a polymer composition having a hydrophilic portion and a hydrophobic portion, wherein the hydrophobic portion of the copolymer binds with the soil particle surface and the hydrophilic portion of the copolymer can bind with water. This results in the prevention, arrest or decelerated loss of water from the targeted area, for example the plant root zone, which allows for improved water usage efficiency by plants, grasses, vegetation, etc.
