Mejora de la fertilidad de un suelo de cultivo tratado con materiales orgánicos
TL;DRAbstract
A 3-year field experiment was carried out to study the effect of deep fertilization of three organic materials (an olive mill waste water sludge compost, CA, a municipal solid waste compost, CRSU, and a paper mill waste, RP) on the chemical fertility of a sandy, poor in organic matter soil, sup- porting strawberry crop. Throughout the experiment a progressive increase of the contents of total orga- nic carbon (COT), and Kjeldahl-N, and of the concentrations of available-P, -K, -Ca and -Mg of the soil was observed. At the end of the experiment increases of COT and available-P were very noticeable, espe- cially in soils fertilized with CRSU and RP. Also, it was especially remarkable at the end of the experi- ment, the increase of Kjeldahl-N in the soil fertilized with CRSU, and the increase of available-K in that treated with CA.
