Heavy metals partioning in three French forest soils by sequential extraction procedure [PDF]

open access: yes, 2003
To know the concentration of heavy metal associated to chemical compounds is important to evaluate the environmental risks on soils, particularly regarding ion bioavailability.

Estimating bioavailable reserves and potential leaching of soil P by simple chemical tests [PDF]

open access: yes, 2008
The amounts of P extracted with acid ammonium acetate are significantly correlated with the bioavailable P reserves of Finnish soils. Together with clay percentage the simple extraction method is fairly reliable.

Heavy metal distribution in some French forest soils: evidence for atmospheric contamination [PDF]

open access: yes, 2003
This study is one of very few dealing with the distribution and the origin of heavy metals in French soils from a priori non-polluted forest areas. The abundance of heavy metals measured in these soils decreases as follows: Cr) Zn)Pb)Ni)Cu)Co4Cd. Total

Mechanisms of adaptation of small grains to soil acidity [PDF]

open access: yesZbornik Matice Srpske za Prirodne Nauke, 2010
Acid soils limit crop production on 30-40% of the world's arable land and up to 70% of the world's potentially arable land. Over 60% of the total arable lands in Serbia are acid soils.

Marker-assisted breeding for TaALMT1, a major gene conferring aluminium tolerance to wheat

open access: yesBiologia Plantarum, 2015
Aluminium toxicity in acid soils is the main limitation to crop production worldwide. In wheat (Triticum aestivum L.), the Al-activated malate transporter (TaALMT1) gene located on chromosome 4DL is associated with malate efflux and Al-tolerance.

Response of Eggplant to Integrated Approaches for Sustainable Reclamation and Improvement of a Cheringa Hot Spot of Acid Sulfate Soil [PDF]

open access: yes, 2008
The application of basic slag (BS20 and BS30: basic slag 20 and 30 t ha-1) and aggregate size (A20 and A30: aggregate sizes of soil less than 20 and 20-30 mm) and different techniques (Tech 1: pyrite at top, jarosite at middle, and top soil at the bottom

Tracing sources of cadmium in agricultural soils: a stable isotope approach [PDF]

open access: yes, 2018
Cadmium (Cd) is a biotoxic heavy metal, which is accumulated by plants and animals and thereby enters the human food chain (Gray et al. 2003). The application of phosphate fertilisers has also resulted in the long-term accumulation of Cd in agricultural ...

Copper Complexation by Dissolved Organic Matter in arid Soils: A Voltametric Study [PDF]

open access: yes, 2018
A voltammetric method was used to estimate the complexing capacity of water extracts from both desert soils sampled at the root zone of creosote and salt cedar plants, and in soils from interspace or background regions where no vegetative influence was ...

Hudnall-Pirtle Site: An Early Caddoan Mound Complex in Northeast Texas [PDF]

open access: yes, 1991
The Hudnall-Pirtle (41RK4) site is situated on a large T-1 alluvial terrace of the Sabine River in northern Rusk County of Texas. This part of Texas, comm.only referred to as Northeast Texas, is part of the Southern Gulf Coastal Plain, a relatively level,

Recent advances towards understanding and managing Kenyan acid soils for improved crop production

open access: yes, 2014
This review focused on the efforts made to understand and manage Kenyan acid soils by use of inorganic, organic materials (OMs) and crop germplasms tolerant to soil aluminium (Al) toxicity and/or low soil available phosphorus (P). Kenyan acid soils which
