Document Summary

Increased erosion: declining biological activity, the ability of a soil to supply nutrients to a crop. Live in symbiosis with plants: macro-organisms, nematodes, arthropods, presence of harmful organisms, plant diseases, weeds, nematodes. Plant nutrition: study of the uptake, transport, and function of nutrients, plant nutrients (essential elements) required for plant growth, must be required for plant to complete their life cycle. Is universal among plants: no other element will substitute for an essential element, pla(cid:374)ts ha(cid:448)e a (cid:396)e(cid:395)ui(cid:396)e(cid:373)e(cid:374)t fo(cid:396) (cid:272)e(cid:396)tai(cid:374) (cid:862)esse(cid:374)tial(cid:863) ele(cid:373)e(cid:374)ts, 17 chemical elements, 3 obtained from the air, hydrogen, carbon, and oxygen, 14 derived from the soil.
