Congo grass grown in rotation with soybean affects phosphorus bound to soil carbon
(Revista Brasileira de Ciência do Solo, 2014-06-01) [Artigo]
The phosphorus supply to crops in tropical soils is deficient due to its somewhat insoluble nature in soil, and addition of P fertilizers has been necessary to achieve high yields. The objective of this study was to examine ...
Soil phosphorus availability and soybean response to phosphorus starter fertilizer
(Revista Brasileira de Ciência do Solo, 2014-10-01) [Artigo]
Phosphorus fixation in tropical soils may decrease under no-till. In this case, P fertilizer could be surface-spread, which would improve farm operations by decreasing the time spend in reloading the planter with fertilizers. ...
Cotton leaf gas exchange responses to irradiance and leaf aging
(Biologia Plantarum, 2015-06-01) [Artigo]
Cotton (Gossypium hirsutum L.) net photosynthetic rate (P-N) decreased with leaf age and low irradiance, and the interaction of these factors might lead to decreased yields mainly in crops with a high plant density. Shade ...
Guar root and shoot growth as affected by soil compaction
(Pesquisa Agropecuaria Tropical, 2018-04-01) [Artigo]
Guar (Cyamopsis tetragonoloba L.) is commonly grown in arid lands, because of its high drought-tolerance. However, soil compaction may be a limiting factor to its growth. This study aimed to evaluate the guar growth, ...
