Interpretive Summary: Nutritional disorders caused by improper soil conditions, deficiencies, or imbalances caused by incorrect fertilizer management can severly limit pea production. Soil analyses should be conducted before planting to determine soil pH and fertilizer needs. Visual symptoms of nutritional disorders usually occur in defined patterns depending on the element involved. This chapter describes appropriate ranges of specific elements necessary in soil and plant tissue to enhance healthy growth and yield of peas. It also describes the impact of soil pH on nutrient availability and pea growth. The visual symptoms of nutrient deficiences and how to correct deficiencies in nitrogen, phosphorus, potasium, sulfur, magnesium, calcium, iron, manganese, zinc, copper, boron and molybdenum are provided. Nutrient toxicities to peas are also described for aluminum, boron, manganese and salt. Symptoms of fertilizer injury are also addressed.
