Cropnuts offers a service combining satellite crop imagery and Normalized Difference Vegetation Index (NDVI) processing to improve the farming efficiency.

The NDVI is an index which allows the farmer to assess the health of the crops and it is calculated based on the light reflectance of plant tissue. The NDVI values range between 0 and 1, where 0 represents bare ground and 1 represents a healthy photosynthesizing crop.

Through satellite imagery we can take pictures of your fields at 15 days intervals (cloud cover permitting) process these photos and create NDVI maps with a resolution of up to 15m. This process can be donethroughout the crop development stages helping us identify problem areas andenabling us to target sampling and create application maps for topdressing.

Satellite Imagery

We can also process the NDVI maps of past seasons to assess the performance of the fields and identify areas that are constantly performing well and areas that are constantly performing badly, i.e. productionor management zones. This allows us to provide support on managing the different zones most efficiently according to their intrinsic differences. Sub-dividing fields into management zones allows for a more cost effective farming management since the application of inputs (fertilizers, seeds, etc.) will be differentiated for each zone and dictated by the properties of each zone.

 

Satellite imagery enables the growers to:

  • Monitor crop health throughout the season
  • Identify problem areas and tackle the problem immediately
  • Generate management zones through processing of past imagery
  • Variable management of fields according to management zones for efficient use of inputs
