The importance of agronomy provides farmers with agricultural information about how to grow and care for plants and soils in certain environments. Factors such as climate, roots, moisture, weeds, pests, fungi, and erosion can pose significant challenges when farmers attempt to produce a plentiful harvest. The Work of Agronomists is concerned with the principles and practice of soil management and field crop production. Agronomists conduct tests so they can figure out the best way to use land. Typical duties include measuring soil salinity and nutrient levels, performing statistical analysis of data and planting crops.
