Abstract

Tlo i voda predstavljaju najznačajnije, ali ujedno i najugroženije prirodne resurse. Degradacija kvalitete tla posljedica je dugotrajne i prekomjerne primjene agrokemikalija koje uzrokuju pad sadržaja organske tvari, onečišćenje tla pesticidima i teškim metalima. Konvencionalna poljoprivreda je uzgoj monokulture na velikim obradivim površinama s ciljem maksimiziranja prinosa, pri čemu se koriste razna mineralna gnojiva i agrokemikalije. Ovakav način poljoprivredne proizvodnje troši velike količine slatke vode, a osim toga, voda se onečišćuje intenzivnom upotrebom mineralnih gnojiva te nitratima, nitritima, fosfatima, teškim metalima, ali i pesticidima koji se ispiru iz poljoprivrednog tla. Za razliku od konvencionalne, u ekološkoj poljoprivredi uporaba mineralnog gnojiva i raznih agrokemikalije pri proizvodnji je ograničena te se nastoji maksimalno iskoristiti sve potencijale agroekosustava, uz očuvanje prirodnih resursa i okoliša. Uz navedena onečišćenja i degradaciju neobnovljivih prirodnih resursa najviši prioritet treba dati prelasku na ekološku proizvodnju. Dostupnih pedoloških podataka za Stonsko polje nema, kao ni podataka o kvaliteti površinskih voda, što predstavlja temelj za procjenu potencijala polja, ali i prelazak na ekološku proizvodnju. U ovom istraživanju se detaljnije analiziralo stanje tla i voda u Stonskom polju, kako bi se utvrdila mogućnost prelaska na ekološku poljoprivredu. Prema rezultatima analize tla i voda može se zaključiti da Stonsko polje ima veliki potencijal za prelazak na ekološku poljoprivredu.

Abstract (english)

Soil and water are the most important but also the most endangered natural resources. Soil quality degradation is a consequence of long-term and excessive application of agrochemicals that cause a decrease in the content of organic matter, soil contamination with pesticides and heavy metals. Conventional agriculture is the cultivation of monoculture on large arable land to maximize yields using various mineral fertilizers and agrochemicals. This kind of agricultural production consumes large amounts of water. In addition, the water is polluted by the intensive use of mineral fertilizers, nitrates, nitrites, phosphates, heavy metals and pesticides that are leached from soil. Unlike conventional, in organic agriculture, the use of mineral fertilizers and various agrochemicals in production is limited and seeks to maximize the full potential of agroecosystems, while preserving natural resources and the environment. In addition to the mentioned pollution and degradation of the non-renewable natural resources, the highest priority should be the transition to ecological production. There are no available pedological data for the Ston field and data on water quality, which is the basis for assessing the potential of the field and the transition to organic production. In this research, the state of soil and water in the Ston field was analyzed in more detail to determine the possibility of switching to organic farming. According to the soil and water analysis results, it can be concluded that the Ston field has great potential for the transition to organic farming.
