The study of Crop, Soil, and Environmental Sciences includes almost every aspect of land use. Soil scientists specialize in
chemistry, fertility,
microbiology or physics; fertilizers; conservation, land use and water resources; soil mapping, surveying or
testing; reclamation of lands; recycling wastes; and other scientific ecological and practical matters that deal with soil re

In relation
to crops, agronomists (crop scientists) work in areas of plant breeding, genomics, genetics, physiology, weed
science, crop management, forage and pasture production, agricultural chemicals, plan t nutrition, or other studies concerne
with agronomic crop
