A significant component of soil organic matter (SOM) is constituted by disintegrating plant residues containing particularly cellulose and lignin which are resistant to microbial decomposition. Yet, the degradation of lignin may begin already in the early stages of organic matter decomposition if there is a sufficient amount of available saccharides in the soil as these serve as a quick source of energy allowing the microorganisms to produce enzymes for lignin decomposition. The aim of this study was to verify whe...

The submitted paper focuses the issue of using a new technology of Near Infrared Reflectance (NIR) sensors in practice for dosing organic fertilizers based on their composition. The HarvestLab 3000 system was tested in a selected enterprise in terms of its usability in practice. In 2021, an experimental plot was selected in a conventional company situated in the southern part of Czech Republic. The HarvestLab 3000 system with the NIR technology was used for the variable (VR) dosage of digestate as a basic fertiliz...
