Intercropping means growing different crops together in the same field to help each other grow better. It's like having a team of plants that work together to make the whole group stronger.
Let's say you want to grow some corn. Corn grows really tall and needs a lot of nutrients from the soil to grow properly. But if you just plant corn in a big field, the soil can get tired and the corn won't do as well.
So instead, you plant corn in between rows of beans. Beans are different from corn because they take nitrogen from the air and put it in the soil (through some help from bacteria). Corn needs nitrogen to grow, so the beans help the corn by providing it with the nitrogen it needs.
The beans benefit too because corn leaves are large and provide shade, which helps keep the soil moist and cool. The beans also work as a natural weed controller by taking up all the space in the soil, not allowing the weeds to sneak in.
Intercropping helps farmers save space and resources, and it's also better for the environment because it creates a more diverse ecosystem in their fields.
