Sažetak
Biomass from agriculture represents a significant resource for the production of compost, substrate and animal feed, as well as other products with higher added value in the food and pharmaceutical industry. The paper presents a model for calculating biomass from agriculture for certain agricultural crops. The term technical potential is used to calculate the amount of biomass. The sources of data on areas (ha), production (t) and yields (t ha-1) of the most important field crops are data from the Agency for Payments in Agriculture, Fisheries and Rural Development and data from the National Bureau of Statistics. To calculate the technical potential of crop residues, the RenewIslands ADEG methodology was used according to previously published results. The starting point for calculating the technical potential is the production of agricultural crops in a certain area (area and yield). The amount of production is multiplied by the harvest index, which is a coefficient ranging from 0.13 (sugar beet) to 3 (sunflower) to obtain the amount of agricultural biomass that remains after harvesting the crop, called total biomass potential. However, the whole amounts of agricultural residues cannot be used, because a part must be left on the field for incorporation in soil due to increasing humus content (all cereals and industrial crops), a part would be used for animal husbandry (wheat and barley), and a part is simple harvest losses. The technical potential of biomass is calculated by deducting from the total potential the amounts required for incorporation in soil, animal husbandry and harvest losses. The model presents a model for calculating the technical potential of biomass for cereals and industrial crops. The model represents a contribution to the calculation of agricultural residues in some agricultural area in order to understand the potential for further use of these raw materials for the production of value-added products (compost, substrates, animal feed, pharmaceutical and food industry products).
