The only time I've ever seen a farmer plow under a viable crop was when the market was so bad that it would cost more to harvest than it would sell for. The plowed under crop will break down and provide organic fertilizer, so at least it will have some value then.
Other times the farmers plant green crops with the sole intention of plowing them under to improve the land. Legumes and rye grass are popular for that use.

Some farmers began destroying their crops in a desperate attempt to raise crop prices by reducing the supply.

The invention of the plow was a key innovation that helped Neolithic farmers become more productive. The plow enabled farmers to cultivate larger areas of land more efficiently, leading to increased crop yields and food production.
The plow cuts into the top layer of soil, carrying the top sod/crop residue and turning it under a layer of clean black soil which can be used for next years crop.
Farmers contour plow to prevent soil erosion on hilly or sloping land. By plowing perpendicular to the slope, it helps slow down water runoff and reduces soil loss. Contour plowing can also help to conserve moisture and improve crop yields.
The Plow And The Wheel. The Plow Was The First Important Tool Invented To Help Farmers. The Sumerians Used the Wheel For The Plow And/Or Wagons.
John Deere was the inventor of the Steel plow. This plow was self cleaning and didn't wear as fast as the iron plow or wooden plow that farmers were using during that time. The Steel plow was also much lighter in weight to the iron plow. In the midwest there was plenty of rich fertile black soil but it was under all the prairie grass that had grown over the years. The wooden plow wouldn't work because it had to be constantly cleaned in order to plow. The steel plow could plow the prairie grass under and self clean the moldboard so the farmer could continue without stopping.
Clever things Legumes: they have nodules on their roots in which they are able to manufacture nitrates from the nitrogen in the air. Farmers plough in this "green manure" to benifit from this process.
The legumes (peas or beans, usually, though clover is also sown) have been grown as green manure. The crop is ploughed into the ground to 'manure' the following crop, which would be harvested.
Persons who plow (plough). Farmers.

The Sumerian plow revolutionized agriculture by allowing for more efficient and effective tilling of soil, which increased crop yields. This innovation enabled farmers to cultivate larger areas of land more quickly, leading to economic and social advancements in Sumerian society.
