Least limiting water range in soil under crop rotations and chiseling
(Sociedade Brasileira de Ciência do Solo, 2011-05-01)
Soil water availability to plants is affected by soil compaction and other variables. The Least Limiting Water Range (LLWR) comprises soil physical variables affecting root growth and soil water availability, and can be ...
Popcorn (Zea mays L. var. everta) yield and yield components as influenced by the timing of broadcast flaming
(Elsevier B.V., 2010-12-01)
Farmers are interested in producing popcorn under organic production systems and propane flaming could be a significant component of an integrated weed management program. The objective of this study was to collect baseline ...
Alterações de propriedades físicas de um nitossolo vermelho pela sucessão milheto-soja na fase de implantação do sistema de semeadura direta
(2007-07-01)
The aim of this work was to evaluate the effect of a millet-soybean rotation, during the implantation phase of no-tillage system on the physical properties of a Nitossolo Vermelho distroférrico and the dry mass production ...
The primary sources of carbon loss during the crop-establishment period in a subtropical Oxisol under contrasting tillage systems
(Elsevier B.V., 2011-12-01)
The physical protection of mineralizable carbon (C) in aggregates has been identified as the primary mechanism of soil C stabilization. Therefore, it is possible to hypothesize that the disruption of aggregate by soil ...
Orientação geográfica de estufas de polietileno e potenciais de água no solo no cultivo do melão rendilhado híbrido 'nero'
(2006-01-01)
This study aimed to verify the effects of four different minimum soil watler potentials (-30, -40, -50 e -70 kPa) and two different plastic tunnel positions (North-South and East-West) on net melon yield. The results showed ...
