Carbon Sequestration in the Soil by Means of Two Organic Fertilizers in the Guava Agrosystem

Centro de Ciencias Agropecuarias, Universidad Autónoma de Aguascalientes, México

Abstract: The hypothesis raised was that compost and manure increase carbon sequestration in the soil. Therefore, in order to estimate the capture of CO in the soil, the investigation was carried out in the orchards: Mesa del Marqués, Mesa Sembrada and Los Cerritos, the treatments applied are: control (without the application of fertilizers), 3% compost, 3% bovine manure, 5% Compost and 5% of bovine manure, under a completely random design, with three replications. The % MO, was multiplied by the factor 0.58 obtaining %CO. The soil weight (ton, ha-1) was estimated and by the formula: tCha-1 = PS x %CO/100, carbon stocks were estimated in the soil. In Mesa del Marqués, with 5% compost, the catch was 44.79 tC/ha and with 5% of manure of 38.6 tC/ha. In Mesa Sembrada, with 3% of compost was captured 42.4 tC/ha; with 5% of compost the catch was 151.07 tc/ha, and with 5% of manure the catch was 90.53 tc/ha. In Los Cerritos, with 5% of compost, 42.80 tC/ha was captured and with 5% of manure, 19.09 tC/ha. Compost and manure in the percentages used increased carbon sequestration in the soil.
