Phosphorus availability and dynamics in soil affected by long-term ruzigrass cover crop
(Geoderma, 2019-03-01) [Artigo]
The use of grasses as cover crops in the off-season of cash crops under no-till has been largely adopted. However, soil phosphorus (P) uptake was previously shown to be reduced when ruzigrass is introduced in the rotation, ...
Ammonium Improves Corn Phosphorus Acquisition Through Changes in the Rhizosphere Processes and Root Morphology
(Pedosphere, 2019-08-01) [Carta]
Physiological and biochemical impacts of silicon against water deficit in sugarcane
(Acta Physiologiae Plantarum, 2019-12-01) [Artigo]
Silicon (Si) has been reported to minimize the impacts of water deficit, even though it is not considered an essential plant element. Sugarcane is highly impacted by water deficit and has a particular and complex mechanism ...
Nitrogen source and rate effects on irrigated potato in tropical sandy soils
(Agronomy Journal, 2019-01-01) [Artigo]
A suitable N source and an optimal application rate can improve the N-use efficiency of potato (Solanum tuberosum L.) while minimizing N losses, especially when potato is grown in sandy soils. Three experiments were conducted ...
Mitigation of ammonia volatilisation from urea with micronised sulfur applied to common bean
(Soil Research, 2019-01-01) [Artigo]
Urea with micronised sulfur (S) in granules may result in lower nitrogen (N) depletion through ammoniacal N (NH3-N) loss than conventional urea due to the acidification reaction of S near urea granules in soil, and the ...
Chemical and physical attributes of an Ultisol under sustainable agricultural production systems
(Revista Brasileira De Ciencias Agrarias-agraria, 2019-01-01) [Artigo]
This study aimed to evaluate the effect of four production systems: agrosilvopastoral; pasture; agropastoral and notillage, all compared to a native forest area (Cerrado), on the chemical and physical attributes of an ...
Assessing the long-term effects of zero-tillage on the macroporosity of Brazilian soils using X-ray Computed Tomography
(Geoderma, 2019-03-01) [Artigo]
Zero-tillage (ZT) is being increasingly adopted globally as a conservationist management system due to the environmental and agronomic benefits it provides. However, there remains little information on the tillage effect ...
Ruzigrass root persistence and soybean root growth
(Plant And Soil, 2019-09-01) [Artigo]
Aims Cropping systems using forage grasses as cover crops have been effective in soil conservation and nutrient cycling, but root persistence of ruzigrass (Urochloa ruziziensis) is significant, and may impair root growth ...
Use of stable isotopes of carbon to detect coconut water adulteration
(Scientia Agricola, 2019-05-01) [Artigo]
Industrialized coconut water may have been adulterated by adding sugar above the limit permitted by law. According to Brazilian law, industrialized coconut water can receive the maximum addition of 1 g of sugar per 100 mL ...
A molecular framework for the embryo growth in germinating seeds of Solanum lycocarpum A. St.-Hil., a nurse plant species
(Annals of Applied Biology, 2019-01-01) [Artigo]
We are clarifying how the functional embryo growth occurs in germinating seeds of Solanum lycocarpum A. St.-Hil., a nurse plant with a central role in forest dynamics in the Cerrado (a biodiversity hotspot). For that, we ...
