Cultivation of reed canary grass Phalaris arundinacea L. for biogas production: methodology for practice
Usťak, Sergej ; Strašil, Zdeněk ; Váňa, Vojtěch ; Honzík, Roman
The basic aim of the methodology is to provide farmers, agricultural advisors, providers of biogas plants and anyone others the basic information about growing and processing for biogas a prospective non-traditional crop - reed canary grass Phalaris arundinacea L. Up to now, a comprehensive methodology for cultivation and utilization of this crop for biogas production is not processed. The publication provides basic botanical characteristics of the crop, specifies its soil and ecological habitat requirements, describes the agricultural technologies for seeding, cultivation, fertilization, plant protection, harvesting and post-harvest ensiling and gives an overview of potential yields of biomass and biogas, especially methane including their economic evaluation.

Processing of biodegradable waste containing raw materials of animal origin into fertilizer substrates: methodology for practice
Usťak, Sergej ; Muňoz, Jakub ; Váňa, Vojtěch
The aim of the methodology is to provide to farmers, agricultural advisors, biogas manufacturers and processors, owners and operators of biogas stations and composting plants, investors and other interested parties, the basic information on the possibilities of hygienic treatment at biodegradable waste containing animal raw materials to fertilizer substrates and the ways of their use. The patented combined method of acid and alkaline biowaste treatment ensures a sufficient stabilization and efficient hygiene of the output product, allowing to be further utilized for composting, biogasification, or for soil application as a valuable fertilizer substrate, as well. A part of the methodology is the evaluation of agrochemical efficiency at output use of fertilizer substrates in the cultivation of selected agricultural crops. The methodology is intended for a wide range of users. The methodology can serve as a basis for the adaptation of technical facilities, technological processes and also as a material for teaching at secondary agricultural schools, agricultural universities or agricultural advisors.
