The Effects of Different Sizes of Particles of a Superabsorbent Polymer on Water Holding Capacity of Two Different Soil Textures

Atefeh Dashtbozorg; Gholamabbas Sayyad; Iraj Kazeminezhad; Mousa Mesgarbashi

Volume 36, Issue 1 , September 2013, Pages 65-75

Abstract
  Superabsorbent polymers are water containers that absorb and retain large quantities of water when applied to the soil. These materials release the absorbed water, allowing the plants to consume adequate amounts of water at all growth stages. One of the best options for increasing the irrigation efficiency ...  Read More
