For optimum forage production, moderate fertility is suggested although forage sorghum will grow on lower fertility soils with better results than corn. Fertilize using soil test recommendations. If a soil test is not available, fertilize at similar rates to corn silage. Silage should be harvested when seed is in the milk to hard dough stage which is the proper moisture level for ensiling. Avoid possible nitrate and prussic acid poisoning by not putting on large applications of nitrogen prior to expected drought periods; do not harvest drought damaged plants within 4 days following a good rain; do not cut within 7 days of a killing frost; cut at a higher stubble height if under stress since nitrates accumulate in the lower stalk, and delay feeding silage 6 to 8 weeks after ensiling to allow prussic acid to dissipate. Never feed forage sorghum to horses.
