You deplete the nutrients in the soil and have to add fertilizer to make up for the loss. With crop rotation you can plant something like corn, that needs nitrogen in the soil, one year and then plant something like soybeans the next year that absorbs (fixes) nitrogen from the air and leaves it in the soil.
Further, without crop rotation the crops have a much greater chance of developing insect or disease problems. Soil erosion can also be worse, depending on which crop is produced.

What is it called when a farmer plants different crops in order to use less nutrients or different nutrients from the soil?
Crop rotation. If you plant the same crop year-after-year. That crop will use up all the nutrients specific to the needs of the plant. Crop rotation involves planting a different crop each year - thus the nutrients in the soil are more evenly used.
When did farmers begin to use crop rotation?
At least 2,000 years ago. Ancient Roman literature details some crop rotation methods.

Why you should do crop rotation practices in place of fertilizers?
For best crop yields, crop rotation cannot take the place of fertilizer use. Most crops can only put back a portion of the nutrients they use, unless nothing is removed from the field. If you take something away, you have to put something back, whether it is an organic fertilizer (manure or compost) or an industrial chemical fertilizer. Crop rotation is better for the soil, though, so less fertilizer is needed.
What are some of the advantages of practising crop rotation?
Crop rotation is the practice of growing a series of dissimilar types of crops in the same area in sequential seasons.Crop rotation confers various benefits to the soil. A traditional element of crop rotation is the replenishment of nitrogen through the use of green manure in sequence with cereals and other crops. Crop rotation also mitigates the build-up of pathogens and pests that often occurs when one species is continuously cropped, and can also improve soil structure and fertility by alternating deep-rooted and shallow-rooted plants.
