From <https://www.ted.com/talks/mohamed_hijri_a_simple_solution_to_the_coming_phosphorus_crisis#t-615427>. Instead of using X phosphorus, which the plant only uptakes 15% of, can reduce to 0.25X, and the plant will take up 90% of that (taking up equivalent phosphorus amounts in absolute terms, but using less phosphorus overall)

A mycorrhiza (from Greek μύκης mýkēs, "fungus", and ῥίζα rhiza, "root"; pl. mycorrhizae, mycorrhiza or mycorrhizas) is a symbiotic association between a fungus and the roots of a vascular host plant, although 29% are non-mycorrhizal plant species. The term mycorrhiza refers to the role of the fungi in the plants' rhizosphere, its root system.

As complex as the chemistry of life may be, the conditions for the vigorous growth of plants often boil down to three numbers, say, 19-12-5. Those are the percentages of nitrogen, phosphorus and potassium, prominently displayed on every package of fertilizer.

Phosphate is a crucial component of DNA, RNA, ATP, and other biologically active compounds. Microbes, plants, and animals-including humans-cannot exist without it. Rocks containing phosphate have been discovered and are being mined at minimal cost. But resources are limited, and phosphate is being dissipated. Future generations ultimately will face problems in obtaining enough to exist.

Lateral Violence occurs within marginalized groups where members strike out at each other as a result of being oppressed. The oppressed become the oppressors of themselves and each other. Common behaviours that prevent positive change from occurring include gossiping, bullying, finger-pointing, backstabbing and shunning.
