The purpose of this report is to present the objectives and the legal framework laid down in the EU strategies for introducing carbon farming practices in soil management, for introducing the principles of the circular economy, as well as for achieving the objectives laid down in the European Green Deal.
The present study uses the method of soil crops to study the fertilization of the soil, changes in the content and forms of nutrients, the effectiveness of various forms of nutrients introduced by the resulting of soil improver – a mixture of waste – wood ash and poultry litter, by means of a vegetation experiment. Sweet pepper Capsicum annuum subsp. macrocarpum L. was selected for the experiment, variety of gate type – Gold medal 7. The results of the study prove the ability to use soil improvers, good resistance of the leaves to sudden intense changes in climatic conditions. The root systems of all mixtures are well developed and strong, stable with good agrochemical parameters compared to that of the zero sample.
The present study examines the possibilities for reclamation of soils contaminated with heavy metals from the extraction of polymetallic ores with soil improvers mixture of waste – sludge from WWTP and ash from thermal power plants, through a vegetation experiment. Two herbaceous species of the genus Rumex were selected for the experiment – R. acetossela and R. patienta known for their ability to accumulate heavy metals and in particular copper. The results of the study prove the ability to use the improvers in biological reclamation of old embankments.
