In the case of dragon fruit cultivation, common in dry tropical climates, its weed control practices can influence soil quality. The objective of this study was to evaluate the effect of dragon fruit (Hylocereus) cultivation management on SOC capture. A Completely Randomized Block Design (CRBD) Factorial was used with 2 levels of cultivation management, differentiated by the weed control method (alternative, with the application of rice husk for yellow dragon fruit, and traditional for red dragon fruit). Additionally, 4 soil depth levels (0-5, 5-10, 10-20, and 20-30 cm) and 2 locations (row and plant) were considered for sampling. The results indicated that the alternative management of yellow dragon fruit led to a greater accumulation of organic carbon beneath the plant compared to the traditional management of red dragon fruit. A significant difference was observed in moisture levels, being higher in the alternative management. Moreover, carbon concentration levels were higher in yellow dragon fruit, especially at a depth of 10-20 cm. In conclusion, the management of dragon fruit cultivation regarding the application of rice husk is associated with higher moisture levels and carbon accumulation. Additionally, it can be attributed that the age of the crop also proves to be a crucial factor in SOC capture. |
