The availability of water for peas and other plants is directly related to how much is in the soil. Clay soils and soils rich in organic matter hold on to water longer, making it more available to plants. Water drains more quickly through sandy soils, making it more susceptible to drought. In a perfect system, water is constantly being taken up by plants and lost through transpiration. Weather factors affect this process. Once temperatures fall at night, they are usually able to rehydrate themselves as the loss rate decreases. Plants that get enough water are also healthier and are better able to handle the stress of disease or insect damage. read less
