Decomposition and Nutrient Release of Cover Crops in Mango Cultivation in Brazilian Semi-Arid Region

Maria do Socorro Conceição de Freitas ORCID logo , Jacob Silva Souto, Mariana Gonçalves, Larissa Emanuelle da Silva Almeida, Alessandra Monteiro Salviano, Vanderlise Giongo


ABSTRACT Knowledge of the decomposition dynamics of aboveground phytomass and its release of nutrients in mixtures of cover crops as well as the impact on the soil tillage system is fundamental for the sustainable management of agroecosystems. This work aimed to evaluate whether soil tillage and the choice of cover crops cultivated in the interrows can be technological strategies to increase dry biomass production, increase the capacity to add carbon, and improve macronutrient cycling in a mango ( Mangifera indica […]

Soil microbial community and mesofauna under dry forest vegetation in the semi-arid region of Paraíba, Brazil

Patrícia Carneiro Souto, Jacob Silva Souto, José Romilson Paes de Miranda, Rivaldo Vital dos Santos, Allyson Rocha Alves


The biological soil activity is responsible for several physical and chemical transformations of deposited organic residues, therefore maintaining the environmental sustainability. The aim of this study was to evaluate the distribution of the soil microbial community and mesofauna in a dry forest (Caatinga) in the semi-arid region of Paraíba, northeastern Brazil. To determine the microorganism population soil samples from the 0-15 cm soil layer were evaluated. Total counts of fungi and bacteria were evaluated in specific culture media. The Berleusse-Tüllgren modified […]

Decomposition of manures applied at different depths in a degraded semi-arid area of the State of Paraíba

Patrícia Carneiro Souto, Jacob Silva Souto, Rivaldo Vital Santos, Gilmar Trindade Araújo, Lauter Silva Souto


This study aimed to evaluate the speed of manure decomposition at different depths. Donkey, cow, goat, and sheep manure was used after stove drying at ± 65 °C. 20 g of each manure was wrapped in nylon bags and applied superficially or buried at 10.0 cm depth. Monthly, a nylon bag/plot was collected. The material was cleaned to evaluate decomposition, oven-dried and weighed to determine the loss percentage in relation to the initial weight. Decomposition was slow in the first thirty days when ± 95 % […]
