Intensive agricultural production can lead to soil health depletion, which can be reduced using conservation practices such as minimum tillage and the incorporation of organic matter. Contrary to conventional tillage practices, conservation tillage leaves at least 30% of crop residue on the soil surface, which helps to minimize soil properties disruption. This study aimed to assess the soil health effect of incorporating biochar saturated with effective microorganisms on the Mollisols-Jacaguas treated with three cover cycles using the combination of four cover crops with three soil tillage treatments, Conventional Plow (CP), Spader and Keyline. The results of this study indicated that incorporating the plant residues of four CC cycles with Keyline tillage had a significant effect on the soil health within the short-term. The interactions of biochar incorporation with CC and tillage treatments had no significant effect on soil pH, LOC, PLFA and Saturated hydraulic conductivity because the small amount of biochar applied (<0.3%) was not sufficient to affect the above-mentioned soil properties at the short-term.
