Our new High Resolution Images tool is just weeks away from being live in our Digital Agronomist platform, and will soon offer sub 1-metre satellite captures of your crops.
Ideal for monitoring crop variability, and irrigation and fertiliser performance in horticulture, viticulture and tree crops this summer, high resolution satellite imagery can detect issues that are tough to spot at ground-level. Supplemented with use of our free 10x10m farm mapping tool, the new service will help you make the right decisions by giving you a greater level of detail.
High resolution satellite imagery can be used to:
- Instantly target issues during critical periods at a resolution suited to intensive permanent cropping
- Pinpoint on-ground issues before scouting and tissue sampling
- Monitor and track crop vigour
- Save time and costs knowing where to tissue or soil test
- Know where to target fertiliser and water applications
- Get multiple image captures during the season, when you need them
How do you interpret high resolution satellite imagery?
As demonstrated in the below images, high resolution satellite imagery shows your NDVI (normalised difference vegetation index) and PCD (Plant Cell Density) on any given day. These are markers of crop vigour and health. The higher the NDVI or PCD, the greater the vigour and health of the plant ortree. Colours are deliberately stretched to allow you to pinpoint good (blue), fair (yellow) and poor performing areas (red) that the naked eye often can’t detect.
As colours are a marker of crop performance on a particular day (not the overall season), a red spot does not necessarily indicate a ‘bad’ area or plant/tree – but it is a sign that you need to either monitor it or take some affirmative action. Low values may indicate poorer health and vigour due to:
- Nutrient deficiency
- Presence of disease/pests
- Poorer growing conditions (soil type/compaction, elevation and drainage)
- Frost/hail damage
Taking this one step further, you can get the most from these insights by combining high res with our Auto Zone tool, which is also part of the Digital Agronomist platform. Auto zone allows you to quickly and easily to generate variable rate application files that are compatible with most farm machinery systems (including John Deere, Case and Trimble). So your applications will apply the right level of seed or fertiliser in the right places – no more, no less.
