Abstract

Biochar has attracted the attention of the scientific community due to its promising applicability and contribution to the elevation of soil chemical and biological aspects, directly influencing the microbiota, fertility levels and yield of agricultural crops. The objective of this study is to determine the chemical and biological attributes of an acrisol cultivated with beans and submitted to the application of ouricuri biochar. The design was completely randomized in a 4 × 4 factorial scheme, with 4 replications. The factors were the combination of four granulometric bands: G1 (0.42 mm), G2 (0.84 mm), G3 (1.19 mm), G4 (1.68 mm) and four biochar doses (8, 16, 24 and 32 Mg ha-1). Then, a control treatment without biochar was added. Morphophysiological aspects of bean culture, and chemical and biological soil indicators were evaluated. Ouricuri biochar promoted improvements in some soil quality indicators. The dose of 32 Mg ha-1 of biochar positively influenced the vegetative development of the plants. The results of this study showed that there is a direct relationship between the particle size and the amount of biochar in the soil. This had a direct effect on the carbon stock of the soil and the microbial population.

Key words: Biocarbon, pyrogenic carbon, soil quality, Phaseolus vulgaris, productivity.
