What is Multispectral?
Multispectral sensing employs various wavelengths of light to capture data from plants, revealing unique spectral signatures. Analyzing these signatures helps assess plant health by detecting stress, diseases, and nutrient deficiencies. This non-invasive technique aids precision agriculture, enabling timely interventions for optimal crop management and improved yields.
Crop Analysis & Variable Rate Application
We first map your block with a smaller drone and can create a multispectral map for detecting the health of any plant, then the spray/spread drone applies spray or fertilser exactly where it is needed for maximum yield from your crop
Healthy leaves reflect a lot of near-infrared light, which we can't detect but multispectral sensors can. So this (red to NIR) part of the spectrum is key to tracking plant health.
We use a multi-spectral camera on our drones to help pinpoint crop stress. It captures the light absorbed and reflected by plants which are not visible to the human eye.
Colours are seen through wavelengths of light. Depending on how plants have absorbed or reflect light results in different colours being seen, usually blue, red and some green light.
Healthy leaves also reflect a lot of near-infrared light, which we also can't detect but multispectral sensors can. So this (red to NIR) part of the spectrum is key to tracking plant health.
Multi-spectral imaging aims to show where there is a lack of nutrients, which means you can concentrate on applying what’s needed to specific plants, instead of blanket spraying – saving time and money.
Step 1
We fly a multispectral drone over the crop to find what areas are stressed
Step 2
We process the field into different zones and decide on a spray or spread rate
Step 3
We send this information to the spray/spread drone and it automatically applies the rate
