MENINO, Regina; CASTELO-BRANCO, Amélia  y  MARTINS, José Casimiro. WWTP sewage sludge: Application in agroforestry soils. Rev. de Ciências Agrárias [online]. 2018, vol.41, n.1, pp.51-60. ISSN 0871-018X.  https://doi.org/10.19084/RCA17227.

Agriculture is one of the obvious targets for recycling "sewage sludge" from WWTP, because of its potential in the physical, chemical and biological correction of agroforestry soils, being an advantageous option if it is ensured - by an analysis performed by a legal entity - that its application is allowed. This analysis, in addition to being an indicator of a possible harmful effect on the environment and on the targeted crop (preventing its use), makes it possible to assess the most adequate amount to be applied in each case, and the remaining deficiencies to be supplied by the chemical fertilization.
