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 presented paper focuses the issue of finding new sources of phosphorus fertilizers to be used in conventional agriculture. Various types of pellets for heating purposes were tested. Based on the determination of phosphorus (P) content in ash obtained from the combustion of pellets produced from plant waste generated during the production of seed materials, it was found out that getting P from this ash is more effective than getting P from the ash of wooden pellets that are commonly used as fuel in households. ...

Potential environmental impacts of growing maize as monoculture lead to efforts focused on finding other potentially suitable crops or their combinations that could replace the pure maize cultures. The most frequent and most effective combination is a mixed crop of maize and legumes. The presented paper deals with the issue of the quality of post-harvest residues when growing maize in the system of mixed cropping. In the field experiment, yield and quality of post-harvest residues were studied during the growing s...

White sweet clover (Melilotus albus Medik.) is a plant species from the group of legumes, and this is why it has a capacity to fix atmospheric nitrogen on the basis of symbiosis with bacteria of the genus Rhizobium that is not available for most plants.The species is used primarily for the production of biomass and for soil remediation. Biomass of white sweet clover can be used in biogas plants. It is also one of important producers of nectar for pollinators. The aim of the experiment was to find out whether the a...
