RELATIONS BETWEEN SOIL SURFACE ROUGHNESS, TORTUOSITY, TILLAGE TREATMENTS, RAINFALL INTENSITY AND SOIL AND WATER LOSSES FROM A RED YELLOW LATOSOL
(SOC BRASILEIRA DE CIENCIA DO SOLOVICOSA, 2013-08-02)
The soil surface roughness increases water retention and infiltration, reduces the runoff volume and speed and influences soil losses by water erosion. Similarly to other parameters, soil roughness is affected by the tillage ...
Soil CO2 efflux following rotary tillage of a tropical soil
(Elsevier B.V., 2014)
Propriedades químicas de um latossolo vermelho de cerrado cultivado com algodão sob diferentes preparos e adubações
(2009-01-01)
The high rate of mineralization of organic matter on savannah soils, which is reached fi ve times faster than in temperate regions, leads us to the challenge of electing the best system of management that maintains and/or ...

Carbon and nitrogen sequestration in soils under different management in the semi-arid Pampa (Argentina)
(Elsevier, 2014-09)
Soil management affects distribution and the stocks of soil organic carbon and total nitrogen. The aim of this study was to evaluate the effect of different crop sequences and tillage systems on the vertical distribution ...
Intercepted solar radiation by maize crops subjected to different tillage systems and water availability levels.
(Pesquisa Agropecuaria brasileira., Brasília, v.45, n.12, p.1331-1341, dez. 2010, 2014)
Nitrogen fertilization, plant density and maize yield cropped under no-tillage systemFertilização nitrogenada, densidade de plantas e rendimento de milho cultivado no sistema plantio direto
(2011-01-01)
In maize (Zea mays L.), the inadequate nitrogen supply and planting density are considered limiting factors to the grain yield. The objective of this study was to evaluate the influence of different nitrogen levels and ...
Parâmetros mecânicos de tração em sistemas de cultivo de melancia
(Universidade Federal de Santa MariaBREngenharia AgrícolaUFSMPrograma de Pós-Graduação em Engenharia Agrícola, 2010-03-29)
In Rio Grande do Sul, Brazil, the watermelon is cultivated in a large area of sandy soils, where the conventional tillage is the most commonly used, favoring the water erosion. This leads the areas under cultivation of ...
Sistemas conservacionistas de manejo do solo para amendoim cultivado em sucessão à cana crua
(Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA), 2007-07-01)
Com o objetivo de avaliar o efeito de sistemas conservacionistas de manejo do solo sobre características agronômicas de cultivares de amendoim com hábitos de crescimento contrastantes, foram instalados sete ensaios de ...
