"Excess release of phosphorus is the main culprit for the eutrophication of freshwater and marine ecosystems [1]. Phosphorus is a nonrenewable and irreplaceable element for plant growth, and its role is crucial in agricultural production [2]. The accelerated growth in food demand has also increased the demand for phosphate fertilizers, which has placed stress on phosphate rock sources and is exhausting existing deposits [3]. The phosphate mining industry is also facing serious challenges regarding water availability for the mining process and a decrease in the quality of phosphate rocks"

"Given that 95 per cent of per capita calorie consumption worldwide comes from crops that grow directly in the soil or from food sources that indirectly rely on it, the symbolic maternal relationship between fertile soil and human life is profound...A system of agriculture, that places healthy soil at the foundation of bountiful and nutrient-rich crops, should form the basis of what 'The Power of the Plate' refers to as a model of "Regenerative Healthcare" in which neither soil nor humans are treated with toxic chemicals."

"The dirt beneath our feet is getting poorer and on many farms worldwide, there is less and less of it." "This article is part of a new multimedia series Follow the Food by BBC Future and BBC World News. Follow the Food investigates how agriculture is responding to the profound challenges of climate change, environmental degradation and a rapidly growing global population. Our food supply chains are increasingly globalised, with crops grown on one continent to be consumed on another. The challenges to farming also span the world."

"Improving the microbial quality of agricultural water through filtration can benefit small farms globally. The incorporation of zero-valent iron (ZVI) into sand filters (ZVI-sand) has been effective in reducing E. coli, Listeria spp., and viruses from agricultural water. This study evaluated ZVI-sand filtration in reducing E. coli levels based on influent water type and the percentage of ZVI in sand filters"
