Quick Answer
Lentils require well-drained, fertile soil with a pH between 6.0 and 7.0 and adequate moisture, especially during germination and flowering stages. Ideal temperatures for growth range from 40°F to 75°F (4°C to 24°C), with cooler temperatures for optimal flavor. Adequate sunlight and moderate wind protection are also necessary.
Soil Preparation and Requirements
Lentils prefer a soil depth of at least 12 inches (30 cm) with a high organic matter content, typically 4-6% or more. This can be achieved by adding 2-3 inches (5-7.5 cm) of compost or well-rotted manure to the soil before planting. A balanced fertilizer application of 10-10-10 NPK (nitrogen-phosphorus-potassium) at the rate of 100-150 pounds per acre is recommended.
Climate, Temperature, and Moisture
Lentils are a cool-season crop and thrive in temperatures between 40°F and 75°F (4°C and 24°C). They require about 30-40 inches (75-100 cm) of annual rainfall or irrigation. Avoid heavy rainfall during flowering and pod formation stages, as this can lead to disease and reduced yields. Plant lentils at the optimal time, typically 8-10 weeks before the last frost date in your area.
Sowing and Plant Establishment
Sow lentils 1 inch (2.5 cm) deep and 2-3 inches (5-7.5 cm) apart, in rows spaced 12-18 inches (30-45 cm) apart. Use a drill seeder or broadcast seeder for optimal germination and establishment. Lentils require about 2-3 weeks to germinate, and 60-70 days to mature. Avoid sowing lentils in areas with standing water or where water tends to collect, as this can lead to root rot and other issues.
