Vliv aplikace plazmatem aktivované vody na půdní strukturu
Jedlička, Jan
Progress can not be stopped even in agriculture, new techniques and technologies are applied and also interconnected with new specializations. In addition, alternative sources for fertilizers and plant protection products are being researched. Recently, the possibility of using plasma-activated water (PAW) in crop production as a source of nitrogen, along with fungicidal and bactericidal effects have been pointed out. For the time being, however, there is no verified effect on soil properties. This work aimed to verify the effect of PAW application on the soil structure, or water resistance of soil aggregates. The values of two types of PAW (PAW-AC, PAW-DBD) were assessed against the control (distilled water). The container experiment was administered in the form of gradual watering of the soil in flower pots and gradual termination in 5 terms (1st term 525 ml, 2nd term 825 ml, 3rd term 1125 ml, 4th term 1425 ml, 5th term 1725 ml). Soil samples were taken from the flowerpots in 3 layers (Top, Center, Bottom) to verify the potential accumulation of fluid efficiency in some parts of the container. From the comparison of two variants of plasma-activated water (PAW-AC and PAW-DBD) with the control (distilled water), it can be seen that neither variant of PAW violates the stability of soil aggregates and therefore the soil structure. Based on the pilot experiment, it would be possible to state that the application of PAW does not worsen the condition of the soil structure and could become part of agricultural management without affecting this property. However, further experiments with other soil types are needed.
