<strong>Title:</strong><br>
Ukraine Soil Nutrient Datasets (2000, 2010, 2020) – Nitrogen, Phosphorus, Potassium, Organic Carbon, pH
<br>
<strong>Description:</strong><br>
This dataset collection provides open-access soil nutrient maps for <strong>Ukraine</strong>, covering the years <strong>2000, 2010, and 2020</strong>. The maps estimate levels of <strong>Nitrogen, Phosphorus, Potassium, Organic Carbon, and pH</strong> across the country at ~250 m spatial resolution.
<br>
Values are derived using multispectral satellite data and physics-based spectral models. The approach is analogous to laboratory spectroscopy, but applied remotely at landscape scale, enabling consistent monitoring of soil fertility across large agricultural regions. Each year and nutrient combination is provided as a single-band GeoTIFF, accompanied by visualization heatmaps and metadata files.
