1. Mechanisms for the Movement of Mn, Fe, B, Cu, Zn, Al and Sr from One Soil to the Surface of Soybean Roots (Glycine max)

Author:
S. Oliver; S. A. Barber

Soil Science Society of America journal 1966 v.30 no.4 pp. 468-470
ISSN:
0361-5995
Subject:
Glycine max; aluminum; climate; copper; ions; iron; manganese; mass flow; roots; soybeans; strontium; subsoil; zinc
Abstract:
... The role of root interception, mass-flow and diffusion in supplying ions to soybeans growing in a leached subsoil was investigated. Root interception was the main mechanism for the supply of Cu, Al and Sr to the soybean roots. Mass-flow was the most important for B and diffusion was the most important for Mn, Fe and Zn. The most significant mechanisms will likely vary with the crop grown, climate ...

Subject:
Glycine max; varieties; soil pH; aluminum; exchangeable cations; varietal resistance; Maryland
Abstract:
... Soybean varieties, representing 10 maturity groups (from North to South), differed significantly in their tolerance to acid Bladen soil (pH 4.4) which contains a high level of KCl-extractable Al. Previous evidence that Al toxicity is the primary growth-limiting factor in this soil, and the observation that varietal differences were minimized or eliminated by liming the soil to pH 5.5, led to the c ...

Abstract:
... Differential aluminum tolerance of ‘Perry’ and ‘Chief’ soybean varieties, determined previously from growth on acid Bladen soil, was confirmed in nutrient solutions containing Al as the known growth-limiting factor. Differences in Al tolerance between the two varieties were steadily increased as the Ca level of the nutrient solution was reduced from 50 to 8 to 2 ppm. Aluminum toxicity in soybeans ...

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:
... Shallow rooting and susceptibility to drought are believed to be caused, at least in part, by strongly acidic (pH < 5.5, 1:1 soil-water), aluminum (Al)-toxic subsoils. However, this hypothesis has not been clearly confirmed under field conditions. The Al toxicity hypothesis was tested on a map unit of Matawan-Hammonton loam (0-2% slope) on unlimed and limed field plots (pH range 5.1 to 5.8) at Bel ...

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 ...

Seedlings of two soybean genotypes, BX10 [aluminum (Al)-tolerant] and BD2 (Al-sensitive), were treated with Al to evaluate the relative root growth (RRG), callose content, Al-sensitive zone, lipid peroxidation, and the anti-oxidative enzyme activities by histochemical and biochemical assays. Under Al toxicity, the RRG reduction of BD2 was more significant than that of BX10, while callose content d ...

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:
... Additions of micromolar concentrations of magnesium (Mg) to hydroponics enhance aluminum (Al) tolerance of soybean by increasing citrate secretion from roots and external complexation of toxic Al species. The objective of this study was to assess the ameliorative effect of Mg additions on soybean root elongation into mineralogically different acid soils. Roots of soybean seedlings grew for 28 days ...

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. Jiyu 70 to investiga ...

Abstract:
... Gypsum has been used in tropical and subtropical agriculture when subsoil acidity is an important yield-limiting factor. However, the conditions that promote increased crop yield as a result of gypsum addition in no-till (NT) systems still remain unclear. A field trial examined the effects of newly and previously surface-applied gypsum in a long-term NT system on the soil chemical properties and n ...
