Agriculture is like a big farm where farmers use land, tools, and animals to grow plants and crops for us to eat. But sometimes, when farmers finish harvesting, there are things leftover that they don't use. These are called agricultural wastes.
For example, when farmers grow rice, they remove the rice grains from the stalks. The stalks are agricultural wastes because people don't use them to make food. The same happens with other crops, like corn or wheat, where the stalks and leaves are removed to get the food.
These agricultural wastes can be big problems for the environment because they can take up a lot of space and release gases like methane that are bad for the air we breathe. So, it's important to find ways to use these agricultural wastes in helpful ways.
Luckily, people have found ways to use these agricultural wastes in useful ways. Sometimes, they can turn them into fuel for the farm equipment or heat for buildings. Other times, they can use these agricultural wastes to create compost, which is a kind of soil that helps plants grow better.
Overall, although these leftover materials may not seem very useful at first, there are actually many different creative ways to put them to good use and keep our planet healthy!
