Resumo
O uso racional de resíduos industriais e urbanos na agricultura traz benefícios químicos, físicos e microbiológicos ao solo. Estes benefícios podem ser atribuídos também às diferentes espécies de resíduos vegetais presentes na superfície do solo, em sistema de semeadura direta. A associação destas práticas favorece ainda mais estas propriedades, pois a elas se somam os benefícios de ambas as atividades. O projeto teve por objetivo estudar a aplicação de diferentes tipos de lodos de esgoto e resíduos industriais na cultura de soja e verificar os efeitos das diferentes espécies vegetais utilizadas como cobertura, em sistema de semeadura direta, nas características químicas e biológicas ao longo do perfil do solo e no desenvolvimento da cultura da soja. O experimento foi conduzido durante os anos agrícolas de 2004/2005, em casa de vegetação, na Faculdade de Ciências Agronômicas FCA / UNESP, Campus de Botucatu. O delineamento experimental foi na forma de blocos ao acaso em esquema fatorial 4 x 4, com quatro repetições. Os tratamentos foram constituídos por quatro diferentes resíduos industriais e urbanos: lodo de esgoto centrifugado, lodo de esgoto de biodigestor, resíduo industrial escória de aciaria e lama cal, além de uma testemunha que corresponde a não aplicação de resíduos. Estes estavam em interação com quatro tipos de espécies vegetais de cobertura: nabiça, aveia, girassol e milheto. Os resultados foram submetidos à análise de variância, pelo teste de média, com valores de significância a 1% de probabilidade. Os resíduos industriais e urbanos testados podem ser considerados materiais alternativos para correção de acidez do solo. Os teores de macro e micro nutrientes do solo foram alteradas pela aplicação dos resíduos industriais, urbanos e pelas plantas de cobertura em todas as profundidades analisadas. A aplicação dos...
The rational use of industrial and urban residues in agriculture brings chemical, physical and microbiological benefits to the ground. These benefits can also be attributed to the different species of vegetal residues gifts in the surface of the ground, in no-tillage system. The association of these practical favors these properties still more, therefore they add the benefits of both the activities. The project had for objective to study the industrial application of different types of sewer silts and residues in the soybean crop and to verify the effect of the different used vegetal species as covering, in no-tillage system, the chemical and biological characteristics throughout the profile of the ground and in the development of the soybean crop. The experiment was lead during the agricultural years of 2004/2005, in house of vegetation, the College of Sciences Agronomics - FCA/UNESP, Campus of Botucatu. The experimental delineation was in the form of blocks to perhaps in factorial project 4 x 4, with four repetitions. The treatments had been constituted by four different industrial and urban residues: centrifuged biosolid, biodigestor biosolid, industrial residue steel furnce and extinct lime, beyond a witness who corresponds not the application of residues. These were in interaction with four types of vegetal species of covering: nabiça, black oats, sunflower and milheto. The results had been submitted to the variance analysis, for the test of average, with values of significance 1% of probability. Tested the industrial and urban residues can be considered material alternative for correction of acidity of the ground. The texts of nutrient macro and micron of the ground had been modified by the application of the industrial, urban residues and for the plants of covering in all the analyzed depths. The application of the industrial, urban residues and the use of the covering plants... (Complete abstract click electronic access below)
