V Sloveniji se je stopnja samooskrbe s prehranskimi proizvodi v zadnjih letih zmanjšala, za nekatere proizvode celo pod polovico. V prispevku so podane kvalitativne ocene možnosti za izboljšanje trenutne stopnje samooskrbe. Ocene temeljijo na primerjalni analizi proizvodnih potencialov kmetijskih zemljišč, projekciji razvojnih trendov na področju kmetijstva in rabe kmetijskih zemljišč ter trendov v potrošnji hrane. Dodana je tudi analiza primerov dobrih praks zagotavljanja lokalne oskrbe s hrano ter rezultati modela MOLAND, ki simulira prihodnje rabe kmetijskih zemljišč glede na možne globalne razvojne scenarije.
A new, ridge-furrow-ridge rainfall harvesting (RFRRH) system covered with black polyethylene (PE) mulch and black perforated PE mulch was studied in the cultivation of purple coneflower (Echinacea purpurea Moench). In the RFRRH system, PE mulch covered two ridges and a furrow between them, which serve as a rainfall harvesting zone. Soil water content, crop yield and production cost effectiveness were evaluated. We conclude that the new RFRRH system could reduce yield and increase material costs, which results in reduced income per hectare. On the other hand, the RFRRH system reduced weed control time and may therefore increase profit per hectare. It supplies at least an equal amount of water in comparison to bare ground (control), and can be used in semi-humid or humid regions without additional irrigation. Copyright
The negative effects of intensive agriculture on the environment, human health, natural resources, etc. require the use of more sustainable farming methods. The decision for organic farming is based on various factors: the personal levels of development and consciousness of the operator of the farm and members of his family, the socioeconomic and size structure of the farm, the type of area in which the farm is located, the availability of the market and the demand for organic products, etc. Organic farming in Slovenia appears to be particularly suitable for smaller farms, since it is more labor intensive, and payments from agricultural policy contribute to the economic efficiency of the farm, despite lower yields. Especially in protected areas, water protected areas, or less favored areas for agriculture, organic farming can be a more convenient farming method. The traditional farming practices that exist are already extensive and the available measures can contribute to farm income and compensate farmers for different services that they provide for the society. The multifunctionality of organic farming (and agriculture in general), i.e., ensuring also the environmental and social roles, is only possible if farming is economical at the same time.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
