Age-old farming traditions have been changed in ways our forebears could barely imagine. Drones in agriculture are now used for 3 main kinds of tasks: crop management, soil and field analysis, and livestock monitoring. Each has its own requirements, and range of UAVs and accompanying software that would be most suited for it. We will carry out a series looking at each of them to help farmers make more informed decisions for their processes. 

For crop management in particular, it comes down to:

- Health Assessment: Drones with multispectral or thermal sensors can identify disease, pest infestation, and water stress in crops at early stages. By detecting these issues early, you can take action to mitigate problems before they snowball into something much worse.
- Yield Prediction: High-resolution images allow farmers to track crop growth and predict yield with high accuracy. This data helps in planning the harvest and logistics for market supply.
- Spraying and Spot Treatment: Here the focus is on applying pesticides, herbicides, and fertilizers to crops, reducing the amount of chemicals used, and minimizing environmental impact. Ensuring that only affected areas are treated also saves resources and reduces costs.

Crop monitoring drones specialize in two of these: health assessment and yield prediction. Here are the top drones for these tasks, and how they help farmers:
