Peas have a relatively shallow root system. Planting peas on cold, poorly drained soils should be avoided, as it favours the development of seedling diseases and root rots. Peas do not tolerate water-saturated or salt-affected soils. The low potential of hydrogen (pH) can inhibit nodulation, reducing nitrogen fixation and plant growth. Most Saskatchewan soils have a pH range suitable for pea growth. Well-drained, clay loam soils are ideal for pea production. They can tolerate some hot weather or drought stress during flowering, but yields may be reduced. The best growing temperature range is when daytime highs are between 13°C and 23°C. Flower abortion can occur at higher temperatures (over 25°C).
