- ... The adaptation of alfalfa (Medicago sativa L.) to well-drained soil has limited its range of culture. The poor performance of this crop in wet soils has often been attributed to the effects of Phytophthora root rot (PRR). However, excess soil water itself may reduce alfalfa growth. The impact of continuous excess soil water stress (ESWS) and PRR stress (PRRS) and the growth potential after elimina ...

- ... Potato plants are more sensitive to soil oxygen stress than many other common crops. Some recent literature suggests this may be due to a relatively high oxygen requirement for tuber growth, rather than a greater requirement for the roots per se. Consequently, the oxygen consumption of growing potato tubers (Solanum tuberosum cv. Russet Burbank) was measured in the field on a Portneuf silt loam (c ...
