Does the major aluminium-resistance gene in wheat, TaALMT1, also confer tolerance to alkaline soils?
(2018-03-01)
Aim: A major limitation to plant growth in acid soils is the prevalence of toxic Al3+. Most genotypic variation for acid soil-tolerance in wheat is linked with the Al3+-activated efflux of malate anions from roots which ...
Patagonian salt marsh soils and oxidizable pedogenic pyrite: solid phases controlling aluminum and iron contents in acidic soil solutions
(Springer, 2018-12)
The sulfidic materials present in salt marshes could be oxidized forming sulfuric acid, increasing the toxic levels of both Al and Fe available to plants. The objectives of this study were: (a) to evaluate the mechanism ...
Tropical soils with high aluminum concentrations cause oxidative stress in two tomato genotypes
(Springer, 2015-03-01)
Tropical and subtropical soils are usually acidic and have high concentrations of aluminum (Al). Aluminum toxicity in plants is caused by the high affinity of the Al cation for cell walls, membranes, and metabolites. In ...
Potato yield and phosphorus nutrition using humic substances in two soil textures
(Empresa Brasil Pesq Agropec, 2020-01-01)
The objective of this work was to evaluate the effect of humic substances (HS) and phosphorus fertilizer on the growth. P uptake, tuber yield, fertilizer P recovery (FPR), and applied P-use efficiency (APUE) of potato ...

Soil organic matter-metal interactions in Chilean volcanic soils under different agronomic management
(MARCEL DEKKER INC, 2002)
The organic matter existing in volcanic soils must be investigated not only in quantity, but also in quality in order to understand its role in soils and thus ensure adequate levels of stable organic polymers contributing ...
Residual effects of superficial liming on tropical soil under no-tillage system
(Empresa Brasil Pesq Agropec, 2016-09-01)
The objective of this work was to evaluate the long-term effects of the surface application of lime on soil fertility and on the mineral nutrition and grain yield of soybean, and of black oat and sorghum in crop succession. ...
