According to the article which are the problems with monoculture farming

One of the major problems of monoculture farming is the variety of species. If there are no varieties in the producer level in the food chain all other organisms within the ecosystem would be affected.

According to the article there are so many problems with the mono-culture are:-

1. Soil erosion

2. Loss of genetic diversity

3. Increased Pesticide use

4. No crop rotation increases fertilizer use

5. Fossil fuel energy replace muscle power

The major problem of mono-culture farming is the variety of species. Mono-culture where the same species is grown year after year, soil structure and quality is poor. It disrupts the natural makeup of the soil and contributes further to nutrient depletion. Mono-culture also creates diseases, which have to be treated with yet more chemicals.
