Precision Ag

Precision agriculture calls for continuous land management at a competitive cost. Localizing and quantifying hotspot areas in fields, orchards and vineyards is now made possible with a variety of indices that can be created using specialist software.
Using the latest multi-spectral sensor, images acquired by UAV are converted to index maps such as NDVIs and NDRE. Variable application maps are created for Ag software or tractor display.
This new technology generates up-to-date information and allows for continuous monitoring and well-structured decision making for any type of plant.

Advantages include:
high resolution remote sensing - ground sampling of 5cm per pixel;
create current aerial maps and identify problem areas;
reduce costs by variable applications - resolution to 50cm;
reduce the impact on the environment;
individually tailored surveys






Healthy plants reflect green and near infrared strongly and from these wavelengths index maps are produced. These will give an indication of chlorophyll activity, and is also correlated to plant biomass, leaf area and plant stress symptoms.

Red areas indicate little or no plants.
Green indicates healthy plants.

Below: the corresponding variable application maps indicate
where different levels of fertiliser can be applied.
