Symptoms of deficiency and initial growth of maize cultivated with biochar unde...
Mendes, Jacqueline da Silva; Chaves, Lucia Helena Garófalo; Fernandes, Josely Dantas; Dantas, Edilma Rodrigues BentoMaize is the second largest agricultural crop in Brazil. It reaches high yields as supported by the intensive use of technologies, particularly mineral fertilization, which is normally costly. To lower production costs and improve crop productivity on small farms, the present study tested the efficiency of poultry litter biochar as a source of nutrients in the initial growth of BRS 2022 maize by the ‘diagnosis ...
Organic carbon mineralization of the biochar and organic compost of poultry lit...
Tito, Gilvanise Alves; Fernandes, Josely Dantas; Chaves, Lucia Helena Garófalo; Guerra, Hugo Orlando Carvallo; Dantas, Edilma Rodrigues BentoThe dynamics of the organic residues added to the soil are closely related to its mineralization rate. Therefore, the present study aimed to evaluate the organic carbon mineralization in soil samples incubated with different doses of biochar and organic compost from poultry litter. Carbon mineralization was evaluated experimentally by measuring the C-CO2 liberated by incubating 200 g of soil mixed with differen...

Study of environment impacts in soils: Acid lead type used car bateries recycle...
Fernandes, Josely Dantas; Dantas, Edilma Rodrigues Bento; Barbosa, Juliana Nóbrega; Barbosa, Edimar AlvesIncreasing number of soils contaminade by lead, can be found nowadays, specialy because of its use in the composition of many industrial products, which are demanded by modern society. For example, lead is used in pipe manufacturing, electrical wire covering, sink, tank and roof manufactering, and specialy in car bateries manufacturing. Thi...
