Lentil is adapted to cool growing conditions, and the young plants are tolerant of spring frosts. This allows for early spring planting dates. Lentils have been grown extensively in the semi-arid parts of the world, where they have slightly lower yields, but good seed quality. High humidity and excessive rainfall during the season encourages vegetative growth, which prevents good yield and can reduce seed quality. Ten to twelve in.
Lentil is adapted to all soil types, from sand to clay loam, if there is good internal drainage.
Lentil does not tolerate flooded or waterlogged soils, and does best on deep, sandy loam soils high in phosphorus and potassium. Good drainage is required, because even short periods of exposure to waterlogged or flooded field conditions kill plants. A soil pH near 7.0 is best for lentil production. Follow the instructions for inoculation, and protect treated seed from high temperatures and drying winds until planted. Various forms of inoculant are available, some of which can be placed in the furrow with the seed.
