Sorghum has low farm input requirements,
Both in terms of fertilisers and plant protection products. It is, to date, little exposed to harmful attacks from bio-aggressive products. Its ability to efficiently absorb a large proportion of the mineral nitrogen from the soil makes sorghum acrop with moderate nitrogen fertiliser requirements. It leaves very little post-harvest residue, thus contributing to lower nitrate losses in water. Incidentally, when excessive nitrogen input combines with high-density soil and elevated hydric stress levels, between the boot and heading stages, the risk of Macrophomina can be heightened.
