Common Uses of Phosphorus- What's the fuss on phosphorus?

Fantastic for fertilizers - it's a component of the complex nucleic acid structure of plants, which regulates protein synthesis. Adding phosphorus to soil low in available phosphorus promotes root growth and winter hardiness and often hastens maturity.

Excellent insect exterminator - speaking of plant health, phosphorus is also effective in killing insects in gardens, because it is toxic to them in small doses and usually won't be any danger to birds.

Makes magnificent matches - red phosphorus is what makes the match light up.
