“…Li et al [11] found that pig manure increased the grain yield between 0.3-and 15.3-fold. In this research, we demonstrated that, when combined with 225 kg¨hm´2 urea at the tillering stage, the yield of high dosage of PS application treatment, T8 and T9, can reach or even exceed the yield of conventional chemical treatment (CK2).…”

“…Microelements such as Cu, Zn, Fe and Mn are indispensable for plant growth [11,35]. When Cu and Zn are used as pig feed additives, they can also be found in high concentrations in some animal manures and may be retained in the soil [15,17].…”

“…Concentrations of Cu and Cd in grain and straw were dependent on the available Cu and Cd in the soils, and soil available Cu and Cd were significantly affected by the soil pH [11]. Heavy metals in variable charge soil are highly bioavailable and easy to transfer into plants.…”

Direct-seeding rice has grown in popularity in recent years and is widespread in China. This study focused on the effects of pig slurry (PS) on grain quality and safety in direct-seeding rice. Application of more than 210 m 3¨h m´2 increased rice yield and dry matter accumulation, compared with conventional chemical fertilizer treatment (CK2). At the heading and maturing stage, a high dosage of PS (T6, T8 and T9 treatments) promoted uptake of Pb, Cu, Zn, Fe and Mn by rice plants and grain, but retarded uptake of Cr, Co and Ni, indicating an ability to alleviate toxicity of some heavy metals. Compared with CK2, PS alleviated the transfer of Pb, Cr, Co, Ni and Cu from straw to grain, but enhanced the transport of Zn, Fe and Mn. Although PS application slightly diminished the processing quality, including brown rice, milled rice and head milled rice, it significantly decreased the amylose content, optimized the starch profile, and improved the overall quality. The results confirmed the feasibility and safety of PS application to direct-seeding rice, and determined that PS basal and panicle fertilizer could increase yield and improve the rice quality when applied between 210 and 240 m 3¨h m´2.

“…In situ remediation techniques were widely used to decrease the phytoavailability of Cd in contaminated soils through the use of amendments such as lime, phosphate, clay minerals, and organic matter (Lee et al 2004, Li et al 2008. Single extraction methods were also frequently used to evaluate the immobilization effects of amendments on Cd in contaminated soils.…”

Various single extractants (EDTA, DTPA, CaCl 2 , NaNO 3 and NH 4 NO 3 ) and the first step of Community Bureau of Reference (BCR1) method were used to evaluate the immobilization of Cd in contaminated acidic paddy soil by different amendments. The extractability of Cd in amended soil changed in the following order: EDTA ≈ BCR1 > DTPA > NH 4 NO 3 ≈ CaCl 2 > NaNO 3 . A simple correlation analysis indicated that the BCR1, CaCl 2 , NH 4 NO 3 , and NaNO 3 methods are the best suited methods for predicting changes in the phytoavailability to rice of Cd in soil (r = 0.680 to 0.828, P < 0.001), followed by the DTPA extraction procedure (r = 0.543 to 0.666, P < 0.01). However, nonsignificant correlations were observed between soil EDTA-extractable Cd and Cd accumulated in rice. Accordingly, the BCR1, CaCl 2 , NH 4 NO 3 , and NaNO 3 extraction procedures are recommended for evaluating the immobilization of Cd in contaminated acidic paddy soil.

“…Various slags, especially those rich in silicates, have been studied for the effect of reduction of mobility of metals by means of changes in soil pH (LI et al, 2008). The basic slag is made of Ca-and Mg-silicates that act as corrective of soil acidity, are sources of Si and alleviate the toxicity of metals in the soil (KIRKHAM, 2006;FERREIRA et al, 2013).…”

-The application of foliar fungicides in vineyards and orchards can increase soil concentration of heavy metals such as copper (Cu) and zinc (Zn), up to the toxicity threshold for fruit trees and cover crops. However, some agronomic practices, such as liming, addition of organic fertilizers, cultivation of soil cover crops and inoculation of young plants with arbuscular mycorrhizal fungi can decrease the availability and the potential of heavy metal toxicity to fruit trees. This review aims to compile and present information about the effects of increasing concentrations of heavy metals, especially Cu and Zn, on soils cultivated with fruit trees and provides some agronomic practices of remediation. Information about the sources of heavy metals found in soils cultivated with fruit trees are presented; mechanisms of absorption, transport, accumulation and potential toxicity to plants are described. Index terms: Trace element, phytotoxicity, growth, fruit trees. METAIS PESADOS EM SOLOS DE VINHEDOS E POMARESRESUMO -A aplicação de fungicidas foliares em vinhedos e pomares pode incrementar os teores de metais pesados, como o cobre (Cu) e o zinco (Zn), em solos e, quando em excesso, podem causar toxidez às frutíferas ou plantas de cobertura. Porém, algumas práticas agronômicas, como a calagem, adição de resíduos orgânicos, cultivo de plantas de cobertura do solo e inoculação de plantas jovens com fungos micorrízicos arbusculares (FMA) podem diminuir a disponibilidade e o potencial de toxidez de metais pesados às frutíferas. A presente revisão objetivou compilar e apresentar informações sobre os efeitos do aumento dos teores de metais pesados, especialmente, Cu e Zn, em solos cultivados com frutíferas e algumas práticas agronômicas de remediação. Ao longo do texto são apresentadas informações sobre as fontes de metais pesados, com enfase no Cu e Zn, em solos cultivados com frutíferas; mecanismos de absorção, transporte, acúmulo e potencial de toxidez às plantas. Além disso, são relatadas algumas práticas agronômicas viáveis para remediar o potencial de toxidez de metais pesados em solos cultivados com frutíferas. Com a adoção destas práticas se espera menor disponibilidade de metais pesados no solo, o que reduziria o potencial de toxidez às plantas, especialmente, em frutíferas jovens transplantadas em solos com alto teor de metais pesados, como o Cu e Zn, permitindo satisfatório crescimento, produção e composição de frutos. Termos para indexação: Elemento traço, fitotoxidez, crescimento, frutíferas.1 (Paper 226-15).
