Abstract

Nepovoljni okolišni uvjeti i neodržive ljudske aktivnosti sve češći su razlozi velikih gubitaka u
voćarskoj proizvodnji. Primjena i istraživanje sigurnih i ekološki prihvatljivih preparata za
organsku proizvodnju bilježe porast. Huminske i fulvinske kiseline, hidrolizati proteina,
aminokiseline, hitozan, korisni kemijski elementi, ekstrakti morskih algi i mikrobni
biostimulatori dokazano mogu igrati ključnu ulogu u smanjenju ovisnosti o gnojivima,
povećanju otpornosti na stres te u povećanju konačnog prinosa i kvalitete plodova. Pozitivno
djelovanje biostimulatora uključuje poboljšan rast korijena, unos hranjivih tvari i proizvodnju
fitohormona, a potvrđena je i osmotska prilagodba u uvjetima abiotskog stresa. Primjena
biostimulatora je ekološki prihvatljiva praksa bez negativnih utjecaja na okoliš, kvalitetu
plodova i ukupni prinos te predstavlja potencijal u rješavanju izazova održivosti u organskim
nasadima, odnosno potencijal za integraciju u upravljanju modernim organskim voćnjacima.

Abstract (english)

Unfavorable environmental conditions and non-sustainable human activities are increasingly
common reasons for large losses in fruit production. The use and research of safe and
environmentally friendly preparations for organic production is increasing. Humic and fulvic
acids, protein hydrolysates, amino acids, chitosan, useful chemical elements, seaweed extracts
and microbial biostimulants have proven to play a key role in reducing the dependence on
fertilizers, increasing the resistance to stress and increasing the final yield and quality of fruits.
The positive effect of biostimulants includes improved root growth, nutrient intake and
phytohormone production. Also, osmotic adjustment in conditions of abiotic stress has been
confirmed. The use of biostimulants is an ecologically acceptable practice without negative
impacts on the environment, fruit quality and overall yield, and represents potential in solving
sustainability challenges in organic plantations, i.e. potential for integration in the management
of modern organic orchards.
