Description
Summary:Superabsorbent polymers (SAPs) are materials that can absorb significant amounts of water relative to their mass. The nature and properties of SAPs make them a widely utilized material across many disciplines. A systematic review was conducted to examine the use of SAPs within agriculture and environmental science. The method of application, rate, and the subsequent impact on soil properties were determined. Superabsorbent polymers can be used to improve and prolong soil water holding capacity, decrease drought stress, and increase time between irrigation events. There are results indicating SAPs can reduce compaction. Yield and plant growth characteristics were improved for all but one of the reviewed studies. While SAPs show potential as a tool, their economic feasibility on large‐scale and long‐term projects should be evaluated.
