摘要：

Synthetic, superabsorbent polymers are soil conditioners developed to aid plant establishment and growth in drought-prone growing media. The effects of a starch co-polymer and a polyacrylamide co-polymer on the establishment and growth of lettuce and barley were investigated. The crops were grown under limited irrigation on a coarse sand substrate. The interval between field capacity and the onset of wilting was increased by up to three-fold in the presence of polymer. Water use efficiency and dry matter production also responded positively to the presence of both the polymers tested.
