MARQUEZ DE LA CRUZ, Jonathan Edilberto et al. Impact of coffee agroecosystem management on soil quality in the four seasons of the year in Tlapacoyan, Veracruz. Cienc. ergo-sum [online]. 2022, vol.29, n.2, e163.  Epub 20-Abr-2021. ISSN 2395-8782.  https://doi.org/10.30878/ces.v29n2a8.

Soils of four coffee plantations (organo-mineral, agroecological management with minimal management, conventional management and agroecological management) with different slopes and management were compared for one year. Soil sampling was carried out by season, organic matter, organic carbon, N, P, K, CEC, pH, texture and microbial respiration were measured. Organic carbon, N, organic matter, and microbial respiration varied. Soils with agroecological management presents higher values of organic matter (10.09%) and microbial respiration (621 µg C.CO2). Organic matter and microbial respiration were similar in coffee plantations with the same slope by season. There is a direct relationship between the content of organic matter, nitrogen with microbial respiration and other soil properties, but not with the coffee yield. Tlapacoyan coffee production decreases, at the pair with the sustainability and quality of the soils because of the adoption of technologies with the use of agrochemicals.
