Análise comparativa das características da serrapilheira e do solo em cafezais (Coffea arabica L.) cultivados em sistema agroflorestal e em monocultura, na Zona da Mata MG

Abstract: O aporte de serrapilheira em sistemas agroflorestais pode melhorar as características químicas e físicas do solo, diminuir a erosão e permitir a manutenção da umidade no solo por mais tempo. Isso faz dele um sistema alternativo de produção de café em regiões com solos propensos à degradação. Este trabalho teve como objetivo realizar uma análise comparativa da quantidade e teor de nutrientes da serrapilheira e das características de fertilidade e do teor de umidade dos solos, em cafeeiros cultivados sob sistema… Show more

“…All indicators were lower in SAF than in RN, and only for climate variablestemperature and humidity -there were no significant difference. Campanha et al (2007), in a study on litter accumulation in agroforestry systems with coffee aged 14, found that SAF contributed with 6.1 mg ha -1 yr -1 of dry litter, while the monoculture contributed with 4.5 mg ha -1 yr -1 , and the agroforestry system presented higher moisture content of 20-40 cm. In our case, these variables showed no significant differences, which may be due to the age of the area, with only five years of implementation.…”

“…Therefore, each isolated factor or interaction between them can provide the coffee different sensory profiles, resulting in no repetition of harvest, in both qualitative and quantitative aspect. The region of Matas de Minas was known for many years as a producer of low-quality natural coffees, mainly due to the accumulation of moisture and high temperature at sowing and drying, factors that contribute to fermentation processes that affect the quality of the product (Campanha et al, 2007;Barbosa et al, 2010). With the adoption and diffusion of new technologies for the processing and drying of coffee, many producers would adhere to the wet processing to improve the quality of the coffee.…”

“…por outro lado, agroecossistemas diversificados, como os sistemas agroflorestais (SAfs), são apontados como meios produtivos mais sustentáveis, propensos a manter a produtividade por um longo período (CASTRo et al, 2009). Também são capazes de cumprir funções ambientais, como aumentar a infiltração da água no solo, diminuir a erosão e colaborar com a conservação da biodiversidade (HUANG et al, 2002;CAMpANHA et al, 2007). Segundo MacDicken e vergara (1990), sistemas agroflorestais podem incluir a combinação de atividades agrícolas, florestais e pecuárias, com objetivo principal de reduzir riscos.…”
