In order to assess the impact of farm management practices on soil fertility, 30 cotton-based farms were randomly selected and monitored in Togo during the growing seasons of the years 2023/2024 in the Savanes, Plateaux-Nord and Maritime regions of Togo. The data collected were analyzed using the “NUtrient MONitoring” (NUTMON) model. The results showed that the mineral Nitrogen balance was positive in 90%, 60% and 33% of farms in the Plateaux-Nord, Maritime and Savanes regions, respectively. The Phosphorus balance was positive in 50%, 11% and 10% in the Maritime, Plateaux-Nord and Savanes regions, whereas the potassium balance was positive in 30%, 20% in the Maritime and Plateaux-Nord. The average partial mineral balance on cotton plots was negative for N (-12.39 kg/ha), P (- 8.78 kg/ha) and K (-17.1 kg/ha) in the Savanes region; positive for N (+10.63 kg/ha) and negative for P (- 4.76 kg/ha) and K (- 2.69 kg/ha) in the Plateaux-Nord; positive for N (+ 2.19 kg/ha) and P (+19.0 kg/ha) but negative for K (-5.2 kg/ha) in the Maritime. Net Operating Income was relatively low in the three regions, denoting a low level of profitability. Knowledge of the flow of each element in the soil that shelters the cotton allowed for suggestions to producers on the order of succession of crops in rotation. It allowed to indicate the site-specific quantities of each nutrient to be provided to the crops that follow the cotton, in order to guarantee the sustainability of cotton-based cropping systems.
