The traditional land evaluation approach\u2014where crop<br \/>\nyield is the dependent variable\u2014was followed using measured yield and net primary productivity data derived from satellite images, together with digital soil and climate maps. In addition to<br \/>\ncharacterizing of soil biomass productivity based on measured data, the weight of soil properties on productivity was also quantified to provide measured soil health and soil quality indicators as an information base for designing sustainable land management practices. To produce these results, we used only the Random Forest method for our calculations. The study considers high-input agriculture, which is predominant in the country. Biomass productivity indices for the main crops (wheat, maize and sunflowers) and general productivity indices were calculated for the whole agricultural area of Hungary. Results can be implemented in cadastral systems, in applied in agricultural and rural development programs. The assessment can be repeated for monitoring purposes to support general monitoring objectives as well as for reporting in relation to the United Nations Sustainable Development Goals. However, on the basis of the results, we also propose a method for periodically updating the assessment, which can also be used for monitoring biomass productivity in the context of climate change, land degradation and the development of cultivation technology<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Keywords:<\/strong> random forest, land evaluation, soil, biomass, Hungary, gross primary productivity, soil health, soil quality<\/p>\n<p>&nbsp;<\/p>\n<p>The article is available <a href=\"https:\/\/www.mdpi.com\/2072-4292\/15\/5\/1236\" target=\"_blank\" rel=\"noopener\" class=\"broken_link\">HERE<\/a>, with full text.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The article was written with the contribution of Tam\u00e1s Hermann, iASK researcher and Gergely T\u00f3th, deputy-director, and was released in Remote Sensing in 2023.<\/p>\n","protected":false},"author":225,"featured_media":27721,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[58,239,97,38,40],"tags":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v16.7 -
