| O uso agrícola de resíduos orgânicos, de origem agrícola, urbana ou industrial, é uma interessante alternativa de disposição, permitindo a reciclagem de nutrientes (NPK) nos ecossistemas. Este trabalho avaliou o efeito da aplicação de lodo de esgoto como fonte de N e de vinhaça como fonte de K comparado ao uso de fontes minerais desses nutrientes sobre a produtividade e variáveis agroindustriais da cana-de-açúcar, por dois anos consecutivos (cana-planta e cana-soca). O experimento foi conduzido em Latossolo Vermelho-Amarelo distrófico típico, em Pontal - SP, e a variedade de cana-de-açúcar avaliada foi a SP 81-3250. Utilizou-se de esquema fatorial 3x2x2+1, ou seja, três tipos de resíduos (lodo de esgoto + KCl; vinhaça + uréia, e lodo de esgoto + vinhaça);... |

| The use of sewage sludge in Brazilian agriculture was regulated by the resolution no. 375 Conama, in 2006. However, there is a lack of research to adequate the mineral N and P fertilizer doses to be applied in agricultural fields treated with this residue. In a field experiment, the effects of application rates of sewage sludge and mineral N and P fertilizers on the productivity and technical characteristics of the cane-plant and first ratoon (residual effect) crops were evaluated. Four doses of sewage sludge (0, 3.6, 7.2 and 10.8 t ha-1, dry base), of N (0, 30, 60 and 90 kg ha-1) and of P2O5 (0, 60, 120 and 180 kg ha-1) were combined in a factorial and laid out on randomized block design, a with two replications. To evaluate the residual effect of the... |

| Sewage sludge is a residue from waste water treatment plants and vinasse is a main effluent from alcohol distilleries. The main differences between them are observed in the nitrogen (N) and potassium (K) contents. Sewage sludge is poor in K, and the vinasse in N. This research was carried out to evaluate sewage sludge and vinasse effects on the nitrogen contents of the plant-soil system and the effects of their application on planted-cane and 1st. ratoon-cane under field conditions, on a Typic Haplustox, in Pontal, State of São Paulo, Brazil, using the sugarcane cultivar SP81-3250. A randomized blocks experimental design was used with 13 treatments and three replications. The results were organized in a 3 × 2 × 2 factorial scheme (three residue forms, two... |
