Conteúdo: |
A interpretação da análise química do solo permite determinar a dose do fertilizante fosfatado a ser aplicada a fim de melhorar a fertilidade para a cultura da soja. Assim é preponderante a comparação dos teores presentes na análise de solo com classes de suficiência do nutriente. Objetivou-se propor faixas de interpretação para o teor de fósforo (P) no solo, a partir de informações provenientes de experimentos com o manejo da adubação fosfatada na cultura da soja, e que foram conduzidos nas condições edafoclimáticas do cerrado (sudoeste) piauiense. |

The need for solutions that minimize negative environmental impacts, generated by anthropogenic activities, has been increasing. Sewage sludge (SS) has predominantly organic composition and can improve soil characteristics, such as fertility and erosion resistance. Therefore, its application as an amendment for agriculture could be an adequate alternative for its final disposal. However, there is a lack of information concerning SS application in tropical soil, mainly related to the presence of heavy metals that can represent a restriction for soil application. Thus, the objective of this study was to evaluate the effect of different rates of SS application: (i) on some chemical properties of a Brazilian soil (ii) on the potential accumulation of some heavy metals (Fe, Mn, Cu, Zn, Cr, Cd, Co, Ni, Pb) in that soil. The experiment started in 2000 in a Research Station (Embrapa-Meio Ambiente) located in the state of São Paulo (Jaguariúna County). The experimental field design was a randomized block. The treatment consisted of a conventional tillage management of banana (NPK) and three rates of SS applications based on its N content (N/2, N, 2N) and five blocks. The soil samples were collected in the depth of 0-20, 20-40 and 40-60cm on November 2005. Apart from increasing levels of most heavy metals analyzed by simple extraction (Mehlich 1 and DTPA), amending the soil with SS also improve organic matter content and the cation exchange capacity (CEC) in the 0-20cm layer. Evidences of heavy metal translocation with depth were found until 60cm when using Mehlich 1 extraction. No significant differences were found in depth when DTPA extraaction was used, except for Cu. Despite the few years of the SS applications, the study indicated that there is a potential risk of pollution of the soil-water-plant system through the intensive use of this kind of material. This emphasizes the need fot long-term experiments. MenosThe need for solutions that minimize negative environmental impacts, generated by anthropogenic activities, has been increasing.
