Applications of sheep’s wool in the fertilization of agricultural crops: A strategy for its valorization

Resumen

Sheep farming in Mexico, primarily focused on meat production, has lead to an underutilization of sheep wool. However, this material has acquired very low economic value in recent years, making it prone to improper disposal. This review highlights the potential of wool valorization in crop fertilization by exploiting its physical, chemical and biological properties through its transformation into fertilizers, soil amendments, organic composts, and plant biostimulants. Re integration of this by-product can promotes the development of a circular economy within the sheep farming sector.
