Effects of the application of biosolids on some chemical, biological and physical properties in an Andisol from southern Chile
An important issue for soil conservation and waste disposal is the use of biosolids in agriculture and for land reclamation. Most biosolids contain valuable nutrients that could be used to improve soil fertility. The aim of this work was to establish the effects of the application of biosolids on so...
