Crop yield is highly dependent on soil plant-available water, the portion of soil water that can be taken up by plant roots. New research has shown that measured plant-available water capacity correlated with corn yield better in dry years than in normal or wet years. Agreement between measured plant-available water and estimates was weaker in the claypan soils than well-drained soils.
