Accumulation of Zinc and Copper in an Arable Field after Animal Manure Application

Abstract

An experiment was conducted to examine the accumulation and mobility of heavy metals (Zn and Cu) at different depths in three types of arable soils (Brown Lowland soil, Andosol, and Brown Forest soil) amended with cattle and pig farmyard manures for 5 years. Nitric‐perchloric acid digestion was performed for the determination of the total amounts of heavy metals, and 0.1 M hydrochloric acid extraction was performed for the determination of the amounts of soluble heavy metals. Results of the soil analysis indicated that pig farmyard manure application resulted in serious contamination of arable soils with Zn and potentially Cu. Especially, the Brown Forest soil displayed a high ability to accumulate heavy metals on the soil surface. Total‐Zn concentration in surface soils was considerably affected by the holding capacity of soluble‐Zn traction. Although the Andosol amended with pig farmyard manure showed higher concentrations of heavy metals related to the higher ability of retention on a weight basis, the soil did not contribute to high heavy metal accumulation because of its low bulk density. Heavy metals were easily leached in sandy soils such as Brown Lowland soil, and Cu was potentially stable compared with Zn. We suggest that long‐term pig farmyard manure application to the Brown Lowland soil and Andosol with a light soil texture is associated with a higher risk of groundwater pollution than the application to the Brown Forest soil.

Accumulation of copper and zinc in soil and plant within ten-year application of different pig manure rates

“…The increases can be attributed to two aspects. On the one hand, pig manure contained high amounts of organic Cu and Zn, which were easily decomposed into soluble Cu and Zn after the application of pig manure to soil (Ogiyama et al 2005). On the other hand, the changes of soil properties caused by the application of pig manure affected metal availability, especially soil organic matter (SOC), which can supply organic chemicals to the soil solution that can serve as chelates and increase metal availability (Asada et al 2010).…”

Simultaneous metal leaching and sludge digestion by thermophilic microorganisms: Effect of solids content

“…Although such application may be beneficial to soil, the negative impacts such as groundwater pollution, pollutant accumulation in soil, etc., should be also considered [1]. Elevated heavy metals concentration in sludge limits the utilization of swine sludge in agriculture and land application [2,3]. There is a need to find an economically feasible and environmentally friendly process to remove heavy metals from swine sludge.…”

Acúmulo de metais pesados e alterações químicas em Cambissolo cultivado com meloeiro

“…A aplicação de esterco de origem animal, dependendo de sua origem, também pode incorporar metais pesados ao solo provenientes sobretudo dos aditivos usados na alimentação animal (O'Neill, 1993). Ogiyama et al (2005), por exemplo, relatam que a adubação com esterco de suíno ocasionou aumento no teor de metais pesados no solo, em especial de Cu e Zn.…”
