1. Conservation system improves soil microbial quality and increases soybean yield in the Northeastern Cerrado
ABSTRACT The conservation tillage systems is based on the surface protection by crop residue and reduced soil disturbance. These two principles can favor the soil quality and promote sustainable agricultural systems. The study was developed with the objective of measure soil microbial biomass, soil basal respiration, enzymatic activity and soybean yield in c

2. Is Increasing Doses of Imazapyr + Imazapic Detrimental to the Main Crop Rotation Alternatives to Flooded Rice?
RESUMO: A mistura formulada de imazapyr + imazapic é o principal herbicida usado para o controle de plantas daninhas em arroz no sistema Clearfield®. O uso contínuo de altas doses pode aumentar sua atividade residual no solo. O objetivo deste trabalho foi determinar a sensibilidade de culturas de cobertura e soja em rotação com arroz irrigado a diferent

3. Soybean in succession to the residue of the sorghum/Paiaguás grass straw with Azospirillum brasilense
ABSTRACT One of the alternatives to achieve agriculture with sustainability and reduction in production costs, mainly with fertilizers, is the formation of straw from the previous crop and the use of genus Azospirillum bacteria. The objective of this study was to evaluate the agronomic characteristics and yield of soybean, cultivated in areas under straw of

4. Methane emission induced by short-chain organic acids in lowland soil
ABSTRACT Methane (CH4) is the second major greenhouse gas after CO2, exerting a significant influence on the climate and the chemistry of the atmosphere. In lowland soil, acetate and H2/CO2 are the most important precursors of CH4 and formed from organic matter fermentation in an anaerobic environment, giving rise to short-chain organic acids (ethanoic, prop

5. Crop residues activity against the free-living stages of small ruminant nematodes
Resumo O efeito nematicida de diferentes materiais orgânicos foi avaliado, com o objetivo de desenvolver um tratamento alternativo não químico do solo para o controle dos estágios de vida livre de nematoides gastrintestinais de pequenos ruminantes. Os materiais orgânicos selecionados foram resíduos da indústria de suco de acerola, caju, uva, goiaba, m

6. Path coefficient analysis, a different approach to identify soil quality indicators
RESUMO Os indicadores de qualidade do solo relacionados à redução da erosão hídrica podem auxiliar no correto manejo do solo. Com o auxílio da análise de trilha, objetivou-se com a pesquisa identificar algumas variáveis que possam ser utilizadas como indicadores de qualidade do solo relacionados à redução da erosão hídrica. A pesquisa foi realiz

7. Potassium chloride: impacts on soil microbial activity and nitrogen mineralization
RESUMO: O cloreto de potássio (KCl) é a fonte de potássio mais utilizada mundialmente e, devido ao uso contínuo desse fertilizante, pode ocorrer acúmulo de sais no solo e nas plantas. O excesso de íons desencadeia uma série de distúrbios fisiológicos, tornando-se um potencial biocida no solo. Objetivou-se avaliar o efeito da aplicação de doses de

8. Nitrous Oxide Emissions in No-Tillage Onion ( Allium cepa L.) Crops Are Increased by Oilseed Radish Cover Crop and Poultry Manure Application
ABSTRACT The use of cover crops and poultry manure (PM) is an alternative to reduce the use of synthetic inputs and can contribute to the nutrient cycling in onions ( Allium cepa L.) grown under a no-tillage system. However, this management practice may contribute to an increase in N2O emissions to the atmosphere. The aims of this study were to evaluate the

9. Winter Species Promote Phytoremediation of Soil Contaminated with Protox-Inhibiting Herbicides
RESUMO: A fitorremediação compreende uma das principais formas de descontaminação de substâncias orgânicas e inorgânicas no solo, economicamente viável e de baixo impacto ambiental. Objetivou-se com este trabalho verificar a eficiência de espécies vegetais de inverno na fitorremediação de solo contaminado com fomesafen e sulfentrazone, utilizando

10. 2D, 3D and Hybrid QSAR Studies of Nostoclide Analogues as Inhibitors of the Photosystem II
Synthetic herbicides are widely used for weed control in crops. Continuous application of chemicals induces the adaptation of weeds, leading to the development of resistance. Therefore, research for novel synthetic herbicides plays an important role in crop protection and food production. Within this context, it is important to understand the relationship be

11. Crop residue harvest for bioenergy production and its implications on soil functioning and plant growth: A review
ABSTRACT: The use of crop residues as a bioenergy feedstock is considered a potential strategy to mitigate greenhouse gas (GHG) emissions. However, indiscriminate harvesting of crop residues can induce deleterious effects on soil functioning, plant growth and other ecosystem services. Here, we have summarized the information available in the literature to id

12. Performance of Flooded Rice Grown in Succession to Winter Cover Crops
ABSTRACT: Mean grain yield of flooded rice in southern Brazil has increased in recent years due to the use of high-yield cultivars and improvement of crop management practices. Nevertheless, stagnation in grain yields has been observed in some rice-producing regions. Adoption of conservation tillage systems based on cover crops may be a strategy to increase
