The soil temperature should exceed 12 °C at drilling
The nutrient demand is similar to that of maize.
Sorghum originates from Africa and has similar requirements to maize, but with a very low water demand and high heat tolerance. The dense and deep root system efficiently extracts water and nutrients from the soil and the plants are capable of regenerating after severe drought stress and wilt.
The field should be free of weeds, due to the relatively slow development of young plants. The required soil temperature of 12 to 14 °C is reached relatively late in the year.
