Effect of cassava mill effluent on biological activity of soil microbial community
(Environmental Monitoring and Assessment, 2019)
The impact of applications of sugar cane filter cake and vinasse on soil fertility factors in fields having four different crop rotations practices in Brazil
(2018-01-01)
In this study we examined how the use of vinasse and filter cake as fertilizers at four different sites alters crop yields of sugarcane. The objective was to determine the impacts based on the products fertility and to ...
Physical-chemical and microbiological changes in Cerrado Soil under differing sugarcane harvest management systems
(BIOMED CENTRAL LTDLONDON, 2012)
Background: Sugarcane cultivation plays an important role in Brazilian economy, and it is expanding fast, mainly due to the increasing demand for ethanol production. In order to understand the impact of sugarcane cultivation ...
Decomposition of 14C-labeled lignins, model humic acid polymers, and fungal melanins in allophanic soils
(1982)
During 1 yr, CO2-C losses from 7 agricultural soils containing 0.5-1.5% organic C ranged from 70 to 243 mg 100 g - 1 while losses from three allophanic soils containing 4.9-8.9% organic C varied from 92 to 191 mg. Losses ...
Use of municipal and industrial sludge in agricultural soil: Responses of soil microbials and soil enzymes
(2009-04-01)
Industrialization has contributed to the increase in the generation of potentially toxic solid residues. Textile and tannery industries produce residues, called sludge, with high organic and inorganic content, including ...
Soil macrofauna as an indicator of soil quality in an undisturbed riparian forest and recovering sites of different ages
(Elsevier B.V., 2013-09-01)
Large expanses of riparian vegetation have been destroyed in Brazil, and few studies have focused on biological indicators of soil quality in Brazilian riparian ecosystems. The aim of this study was to assess relationships ...
