Nitrogen Fate in Terms of Mitigated Influence of Biochar in Soil

Popis výsledku v původním jazyce

Biochar is formed in the thermochemical transformation of plant biomass through pyrolysis. It is considered that biochar improves soil properties, and that its application in the soil increases the carbon sequestration by pumping CO2 out from the atmosphere. It was confirmed in our previous studies, that the freshly applied biochar to soils can worsen the growth of plants. Because of it, the real influence of biochar after dissipation of its initial adverse effects was examined in the next generation of plants cultivated in pots. After the addition of identical inoculums to model plants as was made in the first generation, the soil was tested concerning the fate of nitrogen - in terms of the amount of its mineral forms, their availability in the soil and the rate of leaching. For the second generation of plants five kinds of soil treatments have been prepared with the same indicator plant salad (Lactuca sativa) as in the first generation experiment. Estimation of nitrogen availability in soil and assessment of mineral nitrogen leaching have been investigated using ion exchange resin method. Experimental results have showed the lowest values of nitrogen leaching in terms of inoculum additives along with biochar application that lead to microbial development and consequently to nitrogen immobilization. Nitrogen availability investigation has indicated the increase of its amount released from the microbial biomass after second generation of plants harvesting. Hence, it may be stated that the interactions between soil mixture with biochar, native soil microorganisms and/or bacterial inoculums and experimental plants have been improved during the second plant cultivation.
