Calcium Phosphate Particles Coated with Humic Substances: A Potential Plant Biostimulant from Circular Economy
Nowadays, the use of biostimulants to reduce agrochemical input is a major trend in agriculture. In this work, we report on calcium phosphate particles (CaP) recovered from the circular economy, combined with natural humic substances (HSs), to produce a plant biostimulant. CaPs were obtained by the...
