Influence of biochar application in semi controlled conditions on soil chemical properties

One of the most popular worldwide problem, especially in the last few decades is soil degradation regarding soil oranic matter. The topic is getting more and more important. Soils are one of the largest and most important natural resources of all mankind, therefore it is very important to protect it from various types of degradation. In the absence of sufficient quantities of organic fertilizers, especially manure, it was necessary to use amendment that could be beneficial for soil properties improvement. About ten years ago, the old technology for getting material with high content of carbon, from Amazonia is renewed. In this way is obtained soil enhancer which is well known as biochar. Biochar (biocoal) is possible solution for soil quality improvement in long term. Biochar is solid material obtained in the process of carbonization (pyrolysis) of biomass consisting mainly of plant residues. The aim of this reserach is to analyse effects of biochar appliaction on soil chemical properties such as readily available phosphorus and potassium, humus content, total carbon and soil organic carbon (SOC). During the study, the increasing doses of biochar (0%, 0.5%, 1%, 2% and 3%) were incorporated in five soil types, only once, at the start: alluvium (fluvisol), humogley, eutric cambisol, chernozem - subtype on alluvial sediment and chernozem - subtype on loess. These soil types were selected based on the most common soils used by farmers in the study area (Vojvodina Province, Serbia). Experiment lasted for two years, and the plants (wheat and sunflower) were grown in semi controlled conditions, in pots of 5 l with controlled watering and N fertilization. Biochar application show statistically significant difference between tretmants in content of potassium, soil organic matter, total and organic carbon. It is not determined the statistically significant difference between treatmants in case of content of readily available phosphorus.
