UTRIA-BORGES, E. et al. Agricultural utilization of the biosolids and influence in the tomato crop (Lycopersicon esculentum Mill). Rev. Chapingo Ser.Hortic [online]. 2008, vol.14, n.1, pp.33-39. ISSN 2007-4034.

With the objective of evaluating the response of the growth of tomato seedling (Lycopersicon esculentum Mill) to the biosólidos application in a Ferralitico Red compacted soil, behaved an experiment in pots. In this work the response of the leaf area, seedling height, shoots diameter, radical longitude and dry weight for organs and total of the tomato seedling to cultivated in a soil treated with 135 g of biosolids for kg^-1 of soil was compared with those developed in the natural soil and in the soil treated with mineral fertilizer (urea), to reason of 150 kg of N.ha^-1. The results showed that indicators related with the growth of the seedling responded positively to the biosolids application, where an evident increment was observed in the magnitudes of all the evaluated variables, with similar and superiors results to those of the treatment with mineral fertilizer, what indicates that these residuals have potentialities to be used in systems of seedling production in cultivations that need to be taken to the field.
