Six ways to utilize drone for agriculture

AmazonYaGoogleHave been steadily developing the delivery drones, and the policeDeployment of a drone with a taser gun startedOr,A drone that can fish appearsIt is not only flying, but also various ways of utilizing drones that have been invented. How to utilize such drone in agriculture 6MIT Technology ReviewIt is open to the public.

Six Ways Drones Are Revolutionizing Agriculture

1: Analysis of soil and field
If you create accurate 3D maps using drone at the timing of soil analysis before planting seedlings or planting seedlings in the field, 3D map will help you plan the timing of planting seedlings. Moreover, if soil analysis is carried out after seedlings are planted, the created 3D map becomesIrrigationAnd to manage the nitrogen level of the soil. In other words, using a drone makes it possible to determine a more accurate harvest cycle, which leads to improved harvesting efficiency.

2: Seeding
Several startups are working on the development of a seeding system using drone. The spread rate when using drone has already reached 75% and the cost of seeding can be reduced by 85%. This system is to launch a container containing plant species and nutrients for plants from the drone, to simultaneously bring the species and nutrients necessary for plant growth to the soil.

3: Pesticide spraying
With a distance measuring device making use of ultrasonic echoes and lasers, it has become possible to fly drone at an altitude suitable for each topography and avoid it from obstacles. With these technological advances, Drone measures the distance from the flying height to the ground and evolves to the point where it can adjust the appropriate amount of pesticide in real time. As a result, it seems that presumed data exists that the amount of agricultural chemicals (chemicals) to be sprayed penetrates into the soil and it is possible to complete pesticide spraying five times faster than spraying pesticides using conventional machines .

4: Monitor crops
Large agricultural lands and poor harvesting efficiency are both major obstacles in agriculture. Up to now, the most advanced method of monitoring crops has been described as "a method of using satellite images", but the satellite image accuracy can not be said to be very high, and the disadvantage that further cost is required for further use There was also. However, using drone makes it possible to check the growth situation of crops more accurately at a lower price, and said that it is very suitable for crop management.

5: Irrigation
Drone carries hyperspectral, multispectral, thermal sensors and so on. If you analyze with these sensors, it seems easy to judge which part of the ground is dry and which part will crumble if you add some hands. Therefore, using a drone makes irrigation work more efficient.

6: Evaluation of crop health status
It is very important in agriculture to estimate the health status of crops, the amount of soil bacteria, the presence or absence of fungal infections in trees, etc. By dragging equipment using visible light and near infrared light, it becomes possible to identify how much the plant reflects different amounts of light and near infrared light. With this information multispectral images can be produced, and if used it will be very useful for observing changes in plants and their health status. And quickly responding to changes in plants that can not be seen with such eyes leads to protection of farmland from danger.
