“…This is confirmed at Winchmore by the absence of any enrichment in the control soil which received no P. Gray et al (1999) also found no enrichment of Cd in the control treatment at Winchmore up until 1996, while Schipper et al (2011) found no enrichment of Cd or U in the long-term fertiliser trial at Whatawhata in the Waikato. In contrast, some European studies have found significant enrichment of topsoil Cd concentrations in long-term trials without the addition of phosphatic fertilisers (e.g.…”

“…Schipper et al (2011) hypothesised that the triple superphosphate used at Whatawhata could have been enriched in U. Conversely, the analysis of SSP samples applied each year since 1998 at Winchmore indicated a low mean U concentration of 11 mg kg (1 . Although there has been a significant mean accumulation of Cd over time in the fertiliser trial, there have been notable increases in accumulation, or even decreases, in concentration from one sampling event to the next.…”

“…The loading rate of Cd were even higher than those loading rates through the application of phosphate fertilizer (17.5 g/ha/year, Schipper et al 2011) and sewage sludge (30 g/ha/ year, Baize 2009). To reduce the long-term pollution risk of hazardous elements in sewage sludge, the Council Directive 86/278/EEC recommended the upper loading rate of 100 g/ha/year of Cd to farmlands.…”

Animal manure may be a primary source of cadmium (Cd) to Chinese farmlands because abnormally high values of Cd were observed in various manures. In this study, we evaluated the potential risk of Cd in soil-plant (maize and soybean) system as a result of the long-term (10 years) application of pig manure (PM). During 10 years, the loading rate of Cd through PM application ranged from 26.33-131.50 g/ha/year, while the crops removal rate of Cd was relatively small in comparison to the quantity of Cd supplied by PM application (1.03-4.36 g/ha/year). The PM application significantly increased total Cd concentration in soil. Although the Cd levels did not exceed the Chinese soil quality criteria (1.0 mg/kg dry matter (DM)), it would only take less than two years to reach this limit at high PM application rate. The same trend was also observed for the Cd concentration in maize and soybean. More seriously, Cd concentration in grain of soybean was higher than the threshold values for animal and human ingestion (0.2 mg/kg DM). Based on a mass balance calculation, we found that atmospheric deposition was also an important source of Cd in the experimental area (10.27 g/ha/year). Moreover, the application of PM enhanced the leaching loss of Cd, but they were still fairly small (0.34-0.73 g/ha/year).

“…Portanto, uma grande quantidade de fertilizantes é perdida no solo, contaminando os lençois freáticos e, posteriormente, os lagos e rios, levando-os mesmos à eutrofização (Mózner et al, 2012). Na Nova Zelândia, o uso de fertilizantes fosfatados é considerado o principal fator para a elevada concentração de metais tóxicos no solo, tais como cádmio (Cd) e urânio (U) (Schipper et al, 2011).…”

RESUMOEste experimento teve como objetivo avaliar os efeitos da aplicação em cobertura de diferentes doses de cinzas vegetais e esterco bovino, no desenvolvimento e na produção de videiras cultivar Bordô. As doses utilizadas foram 0, 750, 1.500 e 2.250 g planta -1 de cinzas vegetais e 0, 5, 10 kg planta -1 de esterco bovino em esquema fatorial 4 x 3 (doses cinzas x doses esterco). Em dois anos de experimento foram avaliados o diâmetro de ramos e do tronco, o índice de área foliar, a produtividade, o peso médio dos cachos, o número de cachos e os teores foliares de macro e micronutrientes. Houve efeitos positivos dos tratamentos para todas as variáveis estudadas sem, contudo, alterar o status nutricional da planta em termos de teores foliares dos elementos. De modo geral, a dose de 5 kg planta -1 de esterco acrescido de 1.500 g planta -1 de cinzas vegetais permitiu, para a maioria das variáveis obter os melhores resultados com incrementos no índice de área foliar (38-71%) e na produtividade (106-167%). As duas fontes podem ser usadas de maneira a suprir as exigências nutricionais de videiras em produção necessitando, porém, de uma suplementação com outras fontes.

Bordô using wood ashes and cattle manure in organic system ABSTRACT This assay aimed to evaluate the effects of the superficial application of different doses of wood ashes and cattle manure, on vegetative growth and production of grapevines cv. Bordô. The doses used were 0, 750, 1,500 and 2,250 g plant -1 of wood ashes and 0, 5 and 10 kg plant -1 of cattle manure, in factorial scheme 4 x 3 (doses of ash x manure doses). During two years, the following variables were evaluated: diameter of the trunk and canes, leaf area index, yield, mean weight of cluster, number of clusters and macro and micronutrients contents in leaf. There were positive effects of the treatments for all variables, without, however, changing the nutritional status in terms of contents of elements in leaves. In general, for the majority of the variables, the treatment with 5 kg plant -1 of cattle manure added to 1,500 kg plant -1 of wood ashes, allowed to achieve the best results, with increments in leaf area index (38-71%) and yield (106-167%). The two sources can be used to supply nutritional demands of grapevines in production, needing, nevertheless, a supplementation with other sources.
