Abstract:
... Phosphorus (P) is a critical nutrient for plant growth and makes up about 0.2% of a plant dry matter (Smith et al., 2011), but it is of the most difficult nutrients for plants to acquire. In soil, P may be present in a relatively large amount, but much of it is poorly available to plants due to its low mobility in the acid soil. Low pH, aluminium (Al) toxicity, and low phosphorus (P) often coexist ...

However, soil acidification caused by ammoniacal fertilizers can increase both aluminum toxicity and lime requirement. A field experiment was performed in the period from 2004 to 2012 in Parana State, Brazil, on a loamy, kaolinitic, thermic Typic Hapludox to evaluate the effects of ...

Abstract:
... Aluminum (Al) and manganese (Mn) toxicity are two main constraints to crop production in some acid soils. In the present study, hydroponic experiments were conducted to investigate the phytoxicity caused by the metals Al and Mn in the Al-sensitive soybean (Glycine max) cultivar Jilin62. Results showed that more than 80% of the total cellular Al accumulated in the cell walls of the root tissue. Exc ...

Abstract:
... The concentration of soluble aluminium (Al) in the soil solution increases at low pH and the prevalence of toxic Al³⁺ cations represent the main factor limiting plant growth on acid soils. Citrate secretion from roots is an important Al-tolerance mechanism in many species including soybean. We isolated mitochondria from the roots of an Al-resistant soybean (Glycine max L.) cv.

Abstract:
... Soil pH is an important soil chemical property of acid soils that profoundly affects the growth and nutrient uptake by crops. Five greenhouse experiments were conducted to evaluate responses of common bean (Phaseolus vulgaris L.), lowland rice (Oryza sativa L.), corn (Zea mays L.), soybean (Glycine max L. Merr.). and wheat (Triticum aestivum L.) to mean soil pH values of 4.9, 5.9, 6.4, 6.7, and 7 ...

Abstract:
... Soybean [Glycine max (L.) Merr.] plant introduction PI 416937 (PI4) has an extensive fibrous-like root system that contributes to enhanced drought and Al tolerance. The root system of PI4 appears to be more highly nodulated than standard southern U.S. cultivars, and thus has potential for enhanced N₂ fixation. Genetic transfer of PI4 root system to soybean cultivars may lead to increased seed N at ...

Abstract:
... Soil acidity and aluminum toxicity are serious environmental problems often found in humid temperate and tropical regions or in areas with acid rain. Iron oxidation in soils can also cause high concentrations of H, which, in turn, causes an increase of Al in the soil solution. To examine this problem, a study was undertaken to discover the cause of crop damage in crops planted over buried anode ba ...

When correction of toxicity by management is impractical, an economically sound alternative is to develop AI tolerant cultivars. Heritability (h²) estimates for AI tolerance in hydroponics would aid in the efficient design of selection programs for cultivar development. Our objectives were to determine ...

Although crop seedling root systems are made up of several types of root (e.g., tap, basal, and lateral roots) there has been little attempt to determine their respective sensitivity to abiotic stresses. Most acidic agricultural fields are treated so that they are only slightly or non-Al-toxic in the topsoil with Al-toxicity in the subsoil—effectively stratifying the soil profile relative to Al-to ...

Abstract:
... The soybean is a major crop in the agricultural systems of the Brazilian Cerrados (Savannahs) whose soils are acidic, devoid of nutrients and need to be amended before they are cultivated. However, below the ploughed layer there is a scarcity of nutrients and toxic aluminium (Al). These limit root growth, subsequently causing nutritional imbalance and drought stress. Our aim in the investigation d ...
