Agro-coal as a component in substrata for the production of flowers

This paper examined the influence of agro-coal application as one of the possible components in the substrata for flower production. The agrocoal, also known as bio-coal, is a natural organic component obtained in the process of pyrolysis of wood and other organic residues from the plant, such as straw and corn representing partially burnt carbon-rich material, which is used to improve productive soil-substrata properties. Agro-coal processing in Serbia still has no practical application in agriculture, and due to its soil-substrata properties (increasing porosity, better water and nutrition, as well as beneficial microorganisms), the aim of this paper was to examine the possibility of using agro-coalin substratafor flower production. We selected Pelargonium x hortorum as one of the most commonly cultivated flower cultures. The tested substrata were prepared on the basis of the volume ratio of the components, in which the agro-coal participated with 20% and 30%. The research was carried out on three different hybrids: Dark Red , Shocking pink and Blancheroche. The results of the research showed the justification for the application of agro-coal. By applying 20% in the substrata, it improved the productive properties of the examined hybrids such as a greater number of branches, higher above-ground mass and a greater number of flowers per plant.
