How Does monoculture farming result in smaller crop yields?

Monoculture farming often leads to smaller crop yields due to the depletion of soil nutrients, as the same crop is repeatedly grown in the same area, exhausting specific nutrients required by that plant. This practice also increases vulnerability to pests and diseases, which can spread more rapidly in uniform crops. Additionally, the lack of crop diversity can disrupt the ecosystem, reducing beneficial interactions that promote plant health and resilience. Over time, these factors collectively diminish overall productivity and yield.
