The article deals with thematic content of maps for the large-scale electronic atlas of land cover and land use of university research farms. Maps of different parameters of soil cover, content of nutrients, climatic factors, agricultural crops localization by years of cultivation with combination of remote sensing data as well as application of these maps on agricultural practice are overviewed in the article.
To compile maps, QGIS software was used in combination with online map services, accessible via QGIS plugins, along with the Public cadastral map of Ukraine and cadastral documentation supplied by the university land resources management office. Landsat, Orbview, Ali, Aster, and Sentinel-2 images were used to actualize maps of land use and land parcel borders.
Maps of agricultural crops localization by years of cultivation are useful to control crop rotation and optimal crop placement planning. Maps of organic matter content and hydrolyzible nitrogen content in soils are of primary interest for agronomists, as well as maps of estimation assessment of nutrients to plants.
Also a group of maps that display content of phosphorus, potassium, copper and other elements, important for crop cultivation, were compiled. Agrophysical properties of soils were subject of the other part of our atlas, using these series of maps, agronomists will be able to assess preferable fields for those crops, which have high requirement to soil air and water regime.
Series of maps of the atlas relate to crop productivity, degradation processes, climate conditions, water-protective measures, etc., will help managers to organize agricultural production process and technological operations.
Main procedures for compiling such kind of maps, stages and approaches to map editing are shown. This atlas is a useful large-scale instrument for decision-making in agricultural practice at university research farms.
