because lets say you plant corn one year it takes certian nutrients and the next year you could plant coton because they are in differnt familes and they use differnt nutriets.
Adolf Hitler he used ovens and gas to make feterlizer for crops he did a lot for the crop world
Charles Townshend ... Townshend became the 2nd. Viscount Townshend of Raynham in 1687. He was an able politician, reaching the position of Secretary of State in the reign of George I. He retired from politics in 1730 and turned his attention to his estate in Norfolk. Townshend introduced a new type of crop rotation which was already practised in Holland. It rotated crops on a four year basis and used turnips and clover as two of the crops in the rotation ... Charles Townshend was not the only Townshend to make innovations in agriculture .. Viscount Townshend successfully introduced a new method of crop rotation on his farms. He divided his fields up into four different types of produce with wheat in the first field, clover (or ryegrass) in the second, oats or barley in the third and, in the fourth, turnips or swedes. The turnips were used as fodder to feed livestock in winter. Clover and ryegrass were grazed by livestock. Using this system, he found that he could grow more crops and get a better yield from the land ... If a crop was not rotated, then the nutrient level in the field would go down with time. The yield of the crop from the field decreased. Using the four field system, the land could not only be "rested", but also could be improved by growing other crops. Clover and turnips grown in a field after wheat, barley or oats, naturally replaced nutrients into the soil. None of the fields had to be taken out of use whilst they recovered. Also, where animals grazed on the clover and turnip fields, eating the crop, their droppings helped to manure the soil ...

Crop rotation allows the soil to recover. Proper crop rotation will replace nutrients that are consumed by the previous crop. Planting the same crop year after year will deplete certain nutrients and make the soil unproductive.
The answer you are probably looking for is crop rotation, although it's incorrect to say that he discovered it. He saw how farmers in Belgium were using the technique and introduced it to farmers back in England. Over a period of several years, he did make numerous improvements to the practice.
Show him or her all the benefits to crop rotation. Better fertility, lower disease incidence, lower insect pressure, better soil tilth, and greater diversity make it a really good choice for any farmer.
Crop rotation is important because certain crops deplete nutrients from the soil and overplanting these crops can make the soil unable to support future crops. By rotating crops, this allows nutrients to replenish in the soil naturally, minimizing the need for artificial fertilizers.
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.
In the midwestern part of the US, a very common rotation would be corn the first year or two, then soybeans for a year or two, then wheat, then back to corn. In the western US, a common rotation is wheat, then sugarbeets, then wheat, then dry beans, then corn, then potatoes or another sugarbeet crop, then back to wheat again.
