Plant uptake and DTPA-extractability of Cd, Cu, Ni and Zn in a Norwegian alum shale soil as affected by previous addition of dairy and pig manures and peat

Abstract

. 1998. Plant uptake and DTPA-extractability of Cd, Cu, Ni and Zn in a Norwegian alum shale soil as affected by previous addition of dairy and pig manures and peat. Can. J. Soil Sci. 78: 531-539. Residual effects of cow manure, pig manure and peat soil on the DTPA-extractability and plant uptake of cadmium, copper, nickel and zinc were investigated in the second and third years after application to an alum shale soil. Wheat and barley were grown in alternate years. The effects of the organic matter applied differed among metals, sources of organic matter and time after application. The Cd concentrations in grain was reduced by the rates of peat soil, whereas the manures had no significant effect. Copper concentrations in grain and Zn concentrations in both grain and straw generally increased with rates of organic matter. Nickel concentration in grain tended to decrease with increasing rates of cow and pig manure applied, whereas it tended to increase with the addition of peat soil.The concentrations of DTPA-extractable metals in the soil were generally higher in the second and third years than in the first year after application of organic matter. Some of the metals bound by organic matter in the first year were probably released as the organic matter was decomposed. Decreases in DTPA-extractable Cd and Ni were found by the addition of pig and cow manure, whereas these manures resulted in increased DTPA-extractable Zn. The application of peat soil, on the other hand, resulted in increased amounts of DTPA-extractable Cu, Zn and Ni, probably due to decreased soil pH. o. Les concentrations de nickel dans le grain manifestaient une tendance à la baisse en fonction de l'accroissement des doses des apports de fumier, et à la hausse en fonction des apports de tourbe. Les concentrations de métaux extractibles au DTPA dans le sol étaient généralement plus élevées dans les deuxième et troisième années que dans l'année d'épandage de la matière organique. Certains des métaux liés par la m.o. dans la première année étaient vraisemblablement relargués à mesure que la m.o. se décomposait. Des baisses de Cd et de Ni extractibles au DTPA étaient observées après épandage de fumier de porc ou de vache, l'inverse s'observant pour le Zn. En revanche, l'apport de tourbe se traduisait par une augmentation des concentrations extractibles des trois métaux, probablement reliée à l' abaissement du pH du sol.

Evaluating Dairy Manure as Initial Fertility Driver for Mudflat Soil Amendment

“…In this study, the pH of mudflat soil did not show significant variation between treatments, which is in agreement with findings by Leytem et al [30]. Previous studies found soil pH increased with dairy manure application in alum shale soil [12] and Rosholt soil [31], and did not change in Plano soil [31]. The various effects of DMA on soil pH might be due to original soil pH, OM content and soil buffering capacity.…”

“…Low molecular weight organic matter may increase metal mobility, as it can complex metals previously bound to soil particles [35]. Previous studies have showed increasing available metals concentrations with DMA [12,36]. In addition, release of dissolved organic carbon (DOC) from biodegradation of OM-rich dairy manure may contribute to higher soil available metals concentrations at DMA [37].…”

“…Land application of dairy manure has a great incentive in view of waste disposal, soil amendment, and nutrient recycling and reuse including OM, N, P and other plant nutrients. The past research mainly focused on the application of dairy manure in farmlands [6,7], which showed that land application of dairy manure increased soil OM [8], yield of plant [9][10][11], and heavy metals accumulation in plants [12,13]. Safe disposal of dairy manure is now becoming a challenge in Jiangsu province, due to livestock supporting capacity of cropland based on nitrogen and phosphorus was above the soil carrying capacities in many regions (e.g.…”

Effects of rice straw on the speciation of cadmium (Cd) and copper (Cu) in soils

“…Amendment of soils with organic matter and subsequent decomposition of organic matter may change the soil pH and thereby indirectly affect the distribution and bioavailability of metals. Studies have shown that addition of peat to pig manure increased soluble metal concentration due to decrease in soil pH (Yuan and LavKulich, 1997;Arnesen and Singh, 1998;Almas et al, 2000). On the contrary, alkaline organic amendments may reduce the concentration of metal ions in soil solution by raising soil pH, thereby allowing formation of insoluble metal precipitates, complexes, and secondary minerals (Knox et al, 2001;Basta et al, 2005).…”

Relationship between Selected Metal Concentrations in Korean Raspberry (Rubus coreanus) Plant and Different Chemical Fractions of the Metals in Soil

“…The water soluble and exchangeable metal fractions are usually considered to be directly plant available forms in soil-solution system. Also, diethylenetriaminepentaacetic acid (DTPA)-extractable fraction of the metals from soil (Lindsay and Norvell, 1978) has been widely used to predict a sum of plant available metals (Arnesen and Singh, 1998;Meers et al, 2005;Lee and Ahn, 2010). However, the DTPA-extractable metal fraction in soils is not always correlated to the metal concentration in plants (Sadiq, 1985).…”
