Abstract
Cross-linked polyacrylamide (CLP) has a number of well-established industrial and household uses due to its high water absorbency. Industry has promoted the usage of CLP as a soil water conservation amendment and as a reservoir for plant available water that is helpful in alleviating plant stress during periods of drought. The purpose of this research is to verify that the absorbed water is, in fact, plant available. Following a single drying cycle, and its structural sensitivity to dilute salt solutions, the changes in CLP's water absorption capacity may be serious impediments to its usefulness in filed applications. A field study using CLP banded at the recommended rate and 20 times this rate were performed to test the robustness of CLP to enhance drought tolerance in legumes. The addition of CLP did not sustain yields with reduced irrigation levels. Plant stress indicators, plant growth measurements, and environmental factors were not significant.
