Unfortunately, the indiscriminate application of fertilizers, neglecting the assessment of soil nutrient levels, coupled with the failure to replenish extracted nutrients, has led to a decline in soil fertility. Building on these precedents, the proposal aims to gather data on the availability of nutrients critical for crop development. This initiative arises from the recognition that the conventional chemical analyses conducted in the country's soil laboratories might not consistently provide precise insights into the quantity and accessibility of these essential elements. Consequently, we conducted a comprehensive assessment of nutrient contents, including N, P, K, S, Mg, Fe, Mn, Cu, Zn, and B. This involved employing both the chemical method (Olsen Modified) and a biological evaluation through the missing element method. Our objective was to establish a correlation between these two methodologies, paving the way for the development of a targeted fertilization plan. In the agroforestry system with coffee in La Argelia, the chemical characteristics of the soil in the 0-25 cm layer revealed an acidic pH, medium organic matter content, low electrical conductivity, and a low cation exchange capacity. Notably, there was a discrepancy between the weight of dry matter from the biological evaluation and the concentration of available nutrients obtained through chemical analysis for N, P, Mn, Cu, Fe, and B. The elements experiencing the most pronounced deficiencies were N, P, and S. |
