20.500.12556/DiRROS-28563 Vpliv talnega gnojenja z organskimi in mineralnimi gnojili na prehranjenost, rast in razvoj poročilo o ciljnoraziskovalnem projektu CRP V4-2216 Ohranjanje in izboljšanje proizvodnega potenciala tal za trajnostno pridelavo oljk GO-TO S-OIL V literaturi je malo podatkov o primerjalnih učinkih enake uporabe dušika z različnimi gnojili na rast in pridelek. Za oceno učinkov različnih dušikovih gnojil (mineralno gnojilo (MG), organsko-mineralno gnojilo (OMG) in organsko gnojilo – kozji gnoj, vdelan v tla (OG)) na rast, cvetenje in razvoj plodov oljk v zmernem sredozemskem podnebju je bil v oljčnem nasadu sorte ‘Maurino’ izveden petletni poljski poskus. Rezultati so pokazali, da nizka vsebnost fosforja in kalija v OMG v primerjavi z MG ni pomembno vplivala na rast in pridelek oljk, saj med oljkami, gnojenimi z enim ali drugim gnojilom, ni bilo bistvenih razlik. Vnos kozjega gnoja v tla brez dodatka drugih gnojil je povzročil manjše število plodov in manjšo rast oljk v primerjavi z drugimi gnojili, vendar so bili pridelki v vseh letih bolj enakomerni. Zato bi lahko kozji gnoj, vdelan v tla, predstavljal alternativo konvencionalnim metodam gnojenja v regijah z zmernim sredozemskim podnebjem. Primerjalna analiza laboratorijskih in NIR-meritev za oceno vsebnosti hranil v oljčnih listih je pokazala najboljše ujemanje pri dušiku (R² = 0,78), kar potrjuje potencial NIR-metode za hitro in stroškovno učinkovito spremljanje prehranjenosti oljk. The European Union has set a target to reduce nutrient losses by at least 50% while maintaining soil fer lity. By 2030, fer liser use is to be reduced by at least 20%, with full implementa on of environmental and climate regula ons. The EU's Green Deal also aims for at least 25% of agricultural land in the EU to be under organic farming by 2030. Given that about 50% of the world's popula on depends on agricultural products produced with mineral fer lisers, and that the widespread use of mineral fer lisers in the past was due to their cost-effec veness and easy accessibility, the European fer liser industry now faces a major challenge: developing sustainable fer liser products. Most research has focused on the synergis c effects of combining organic and synthe c fer lisers and on the effects of different fer liser rates on vegeta ve growth, oil quality, and yield. There is li le informa on in the literature on the compara ve effects of uniform nitrogen applica on with different fer lisers on crop growth and yield. To evaluate the effects of different nitrogen fer lisers – mineral fer liser (MG), organo-mineral fer liser (OMG), and organic fer liser (goat manure incorporated into the soil, OG)—on the growth, flowering, and fruit development of olive trees in a temperate Mediterranean climate, a five-year field experiment was conducted in an olive grove planted with the 'Maurino' cul var. The results showed that the lower phosphorus and potassium content of OMG compared to MG had no significant effect on olive tree growth and yield, as there were no significant differences between olive trees fer lised with either product. Incorpora ng goat manure into the soil without adding other fer lisers resulted in fewer fruits and reduced growth of olive trees compared to the other fer lisers, but more uniform yields were observed over the years. Consequently, goat manure incorporated into the soil could be a viable alterna ve to conven onal fer lisa on methods in regions with temperate Mediterranean climates. A compara ve analysis of laboratory measurements and measurements with a NIR spectrometer to assess the mineral content in olive leaves showed the best correla on for nitrogen (R² = 0.78), confirming the poten al of the NIR method for rapid and cost-effec ve monitoring of olive nutri on. oljke oljčniki gnojenje gnojila organska gnojila mineralna gnojila rast oljk prehranjenost oljk true false false Annales ZRS Slovenski jezik Angleški jezik Znanstveno-raziskovalno središče Koper Neznano 2026-03-24 09:15:02 2026-03-24 09:15:03 2026-03-26 04:11:38 0000-00-00 00:00:00 2026 0 Koper 2026 Koper Nasl. z nasl. zaslona; Opis vira z dne 24. 3. 2026; 1 spletni vir (1 datoteka PDF (28 str.)) 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2026-03-24 633.852.73 978-961-7276-08-4 10.35469/978-961-7276-08-4 272408067 2026_03_24_212_WP2-VPLIV-TALNEGA-GNOJENJA-1.pdf 2026_03_24_212_WP2-VPLIV-TALNEGA-GNOJENJA-1.pdf 1 7225DD48D3045D30F2FB2D479B1A0F0C cbbeb84d4cb3c5a5200028aea831aa40ac8ce95befebf2e4adb00f02e3c349ce ec7f2624-2769-11f1-aa40-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=42408 https://www.zrs-kp.si/publikacija/vpliv-talnega-gnojenja/ 1 9276bba9-2759-11f1-aa40-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=42391 Znanstveno-raziskovalno središče Koper / Centro di Ricerche Scientifiche Capodistria 0 0 0
