Fertilizers, food and environment
Although phosphoric fertilizers will continue to play a major role in intensive agriculture, depletion of natural resources and long-term unsustainability necessitate alternative strategies be investigated and implemented to buffer against food insecurity and environmental degradation. Phosphorus is not a renewable resource and its future use in agriculture will be impacted by declining availability and increased cost. Moreover, the striking increase in the use of fertilizers by intensive agriculture practices has led to degradation of air and water quality. This paper offers an overview on the sources and production process of phosphate fertilizers, the sources of environmental contamination due to their production and use, and finally focuses on the use of phosphate-solubilizing bacteria as an alternative to avoid the excessive use of such fertilizers.
