A soil conservationist is the person responsible for making sure that the land stays in healthy shape. People in this position work with the government as well as farmers and private landowners to help solve the problems of erosion, overuse and chemical alteration. Management strategies vary by region and the specific problem. It is common to find soil and water conservationists working together, as soil and water have an effect on each other.
One of the largest problems faced by farmers is nutrient depletion in fields. This can be prevented by rotating crops so that the nutrients used by plants one year are given back to the soil by crops planted the next year. Erosion of fields can be countered by planting a row of trees, referred to as a windbreak, to keep the soil intact, as well as other management techniques. In certain regions, over-salinization, or too much salt, causes the earth to be barren, and there are many techniques that can be utilized to help with this problem, though it can be caused by the wrong type of irrigation system. These are all solutions that a soil conservationist might present to a farmer.
A soil conservationist might also work on the pH levels of a given piece of land. The pH scale is a measuring system used to determine how acidic or base a soil is, and if the pH is too high or too low, use of the soil might be limited. In this instance, it is a soil conservationist's job to figure out why the soil has an improper pH level and figure out how to alter it while making sure it does not harm any nearby waterways.
Soil conservationist jobs may also include the analysis of organisms in the soil. Certain bacteria or fungi are indicative of problems, and a conservationist would work to introduce the correct organisms into the area. The same process is true for minerals in the soil.
To obtain a soil conservationist job, a candidate is usually required to have four or more years of training in the fields of agronomy, agriculture, crop and soil science or environmental science. Most of a person in this position's time is spent in the field performing research and taking corrective action, and it is considered fairly physically demanding. Postgraduate studies are often required for a person in this field to hold a teaching or research position. Depending upon experience and education, a soil conservationist can work on a local, regional or federal level, or work directly with one farmer or landowner.
