There is now a very small drone, about the size of a palm.
They can fly over the fields and help farmers check their crops.
Small drones can take photos, check if plants are sick or have insects, and also help farmers spray pesticides and fertilizers.
Because they are very small, they can fly into small plots of land, which is very suitable for small farmers.
Using drones can reduce the waste of pesticides and water, making farming more environmentally friendly.
Now, farmers in many countries have started using small drones, such as in China, India, the United States, and Brazil.
Scientists are still researching smarter drones that can work on their own to help farmers grow more and better food.
In the future, farming will become smarter and more environmentally friendly.
