Carbon Stocks and Pools in Relation to the Texture of Kaolinitic Soils from the Brazilian East Coast

João Bosco Vasconcellos Gomes, Carlos Alberto Silva, Tamara Letícia de Azevedo Ferreira, Mozart Martins Ferreira, Alberto Vasconcellos Inda, Nilton Curi


ABSTRACT: Extremely kaolinitic soils of Tertiary age elevations on the Brazilian east coast present a wide range of texture, which is recognized as one of the main factors controlling the soil organic matter contents. This study aimed to investigate the organic C storage of different compartments of kaolinitic soils. The studied soils had a wide particle size gradient, were under native forest vegetation, and located on Brazil’s eastern coast (Coruripe – CF, Umbaúba – UF, Nova Viçosa – VF, Sooretama […]

Leather Industry Waste as a Nitrogen Source for Wheat and Rice in Succession

Lívia Cristina Coelho, Mozart Martins Ferreira, Ana Rosa Ribeiro Bastos, Luiz Carlos Alves de Oliveira, Ewerton Dilelis Ferreira


ABSTRACT The stabilization process necessary for leather tanning, in the leather industry, generates a great deal of collagenic solid waste, which is a likely pollutant. This solid waste has high nitrogen content, which suggests potential for agricultural use. To evaluate the feasibility of application of industrial leather waste as an N source for wheat and rice crops, a greenhouse experiment was conducted with five application rates of N from collagen (0, 225, 450, 675, and 900 mg kg-1) and three […]

Assessing the quality of agricultural soils is important for defining and adopting management practices that ensure socioeconomic and environmental sustainability. The methods for indexation of quality indicators called the Integrated Quality Index (IQI) and the Nemoro Quality Index (NQI) were used in this study to evaluate soil quality in experimental plots planted to eucalyptus. The selection of these indicators was made based on nine soil quality indicators: geometric mean diameter, water permeability, organic matter, macro- and microporosity, total porosity, bulk […]
