Soil degradation is recognized as a serious constraint to crop production in sub-Saharan Africa. A study was conducted in Nadion, located in the South Sudan zone of Burkina Faso to assess the impact of no-till, tied ridging; ripping and conventional tillage combined with soil fertility management options on Lixisol structural stability after two years of treatments imposition. The fertility management options were control, 2.5 Mg ha-1 of compost every year, 100 kg ha-1 of NPK + 50 kg ha-1 of Urea, mulching (100 % crop residues applied) and 2.5 Mg ha-1 of compost + 100 kg ha-1 of NPK + 50 kg ha-1 of Urea. The results showed that soil structural stability index (StI) tended to decrease under ripping, tied ridging and conventional tillage practices after two years. The application of organic amendments by improving soil organic carbon storage, tend to improve soil structural stability.
Key words: Fertility management, lixisol, structural stability, tillage
