Tillage and the market price of crops increase on-farm productivity by influencing the input redundancy of biochar and seeds. Family-type agricultural management entities can optimise environmental protection and economic efficiency by selecting different farmland regulation measures, which include the following: 1) Deep ploughing and the application of 500–558.74 kg mu⁻¹ biochar for hard-grain corn are suitable for family farms. 2) Deep ploughing and the application of 500–504.72 kg mu⁻¹ biochar for sticky corn are suitable for large-scale growers. 3) Deep ploughing and the application of 0–40.43 kg mu⁻¹ biochar for sticky corn are suitable for traditional farmers.</div></div><div><h3>Significance</h3><div>This study provides feasible options for the sustainable and green application of biochar under different agricultural management conditions.

The Bagré irrigation scheme in Burkina Faso, with 16,780 ha planned, of which 3380 ha already under cultivation, is emblematic of this renewed interest.

If the high cost of land development (€15,000/ha) explains the allocation of small plots, the economic rationale for spending much money to keep people in poverty and in a more vulnerable situation than before is questionable.
