Outstanding impact of soil tillage on the abundance of soil hydrolases revealed by a metagenomic approach. Abstract: The soil represents the main source of novel biocatalysts and biomolecules of industrial relevance. We searched for hydrolases in silico in four shotgun metagenomes (4,079,223 sequences) obt... ... Repositório: BDPA Ano de publicação: 2018

NO and N2O emissions related to the nitrogen fertilization in a cornfield under No-tillage and tillage sistems. The dynamic of nitrogen oxides emissions from Cerrado soils related to the nitrogen fertilization is still not well known, in spite of the intensification of agricultural activities in this region. NO... ... Repositório: BDPA Ano de publicação: 2004
Microbial diversity in an Oxisol under no-tillage and conventional tillage in southern Brazil. ABSTRACT: The no-tillage (NT) system of soil management is recognized as more sustainable than conventional tillage (CT), with an important role played by soil microorganisms. The objective of this st... ... Repositório: BDPA Ano de publicação: 2014
Bacterial diversity under different tillage and crop rotation systems. Microbial diversity can be used to assess the impact of agricultural practices on the long-term sustainability of cropping systems. The aim of this study was to investigate changes in soil bacterial d... ... Repositório: BDPA Ano de publicação: 2012
Soybean macronutrient availability and yield as affected by tillage system. The effect of tillage system (NT-no tillage; CT-conventional tillage; MT-minimum tillage; and NT/scarification, every three years) on soybean nutrient availability and yield was evaluated on Oxisol af... ...

Tillage systems with controlled traffic and limits to maize production. Soil compaction can reduce the growth of crops, causing production losses even in soil conservation systems. In areas where controlled traffic is used, the wheeled rows are prone to show limiting cond... ... Repositório: BDPA Ano de publicação: 2015
Dry matter decomposition of cover crops in no-tillage cotton system. No-tillage cotton systems require soil coverage with cover crop residue for a longer time due to the late cycle of cotton. However, decomposition rates may vary between cover crops, and the adjustment... ... Repositório: BDPA Ano de publicação: 2018
