Synopsis: Tall wheatgrass grew and produced well at ESP (exchangeable-sodium-percentage) levels between 50 and 60 under field conditions. In the greenhouse, tall wheatgrass germinated and produced at ESP levels of 60, with transplants exhibiting superior performance. Seeds germinated with no adverse effects at pH levels up to 9.7. Plants grew at pH levels of 10.0 in solution culture.
