BALANCING NUTRIENCE IN ORGANIC OLIVE GROWING

Cilj istraživanja bio je utvdriti ciklus hraniva (makroelemenata i mikroelemenata) u ekološkom nasadu masline te izraditi preporuke gnojidbe. Ukupno je analizirano pet uzoraka sa površine od 3 ha na dvije dubine 0-30 i 30-60 cm te su utvrđena osnovna agrokemijska svojstva tla. Prema pH vrijednosti svi uzorci pripadaju klasi slabo alkalnih tala s prosjekom pHKCl 7,24. Prema sadržaju organske tvari uzroci su u skupini vrlo do ekstremno humoznih tala, prema sadržaju karbonata većinom su srednje karbonatni. Najveća heterogenost utvrđena je kod koncentracije fosfora. Za razliku od fosfora kod kalija su utvrđene bogate do ekstremno bogate klase opskrbljenosti. Sadržaj dušika u listu masline kretao se od 1,11 do 1,13 %. Sadržaj fosfora kretao se od 0,11 do 0,20 %. Kod sadržaja kalija utvrđena je različitost unutar uzoraka te se sadržaj kalija kretao od 1,2 do 1,9 %. Koncentracije bakra kretale su se od 4,22 do 5,5 mg/kg. Koncentracije željeza bile su od 37,9 do 54,6 mg/kg dok su koncnentracije mangana bile nešto niže s rasponom od 22,4 do 30,1 mg/kg. Koncentracije cinka također su bile vrlo varijabilne te su se kretale od 13,5 do 22,7 mg/kg. S obzirom na anlizu tla najbolje je koristiti pileće ili kokošje zrelo organsko gnojivo s obzirom na visoki postotak fosfora u tom gnojivu.Organic production ("organic", "bio") is a system of sustainable management in agriculture and forestry. Including cultivation of plants and animals, food production, raw materials, natural fibers and processing of primary products. The aim of study was to determine cycle nutrients (macro and trace elements) in organic olive grove and to make fertilization recommendations . A total of five samples from the surface of 3 hectares at two depths of 0-30 and 30-60 cm were collected, and establishes the basic agrochemical soil properties. According to the pH value of all the samples belong to the class of alkaline soils with low pH KCl average of 7.24. According to the content of organic matter samples belonge in the group of very to extremely humus soil but the content of carbonate are mainly medium carbonate. The greatest heterogeneity was found in concentrations of phosphorus where the AL-P2O5 ranged from 5.82 to 24.44 mg / 100 g of soil. Unlike phosphorus potassium were determined to extremely rich class supply. The nitrogen content in the leaf olive ranged from 1.11 to 1.13%. Phosphorus content ranged from .11 to 0.20%. Potassium content was ranged from 1.2 to 1.9%. Copper concentrations ranged from 4.22 to 5.5 mg / kg. The concentrations of iron were very heterogeneous and statistically, significantly different (P £ 0.05) and ranged from 37.9 to 54.6 mg / kg while manganese were slightly lower with a range of 22.4 to 30.1 mg / kg. The concentrations of zinc have also been highly variable and ranged from 13.5 to 22.7 mg / kg. The concentration of phosphorus in the olives lives were inversely proportional to the concentration of zinc which indicates competition adopting these elements. Due to the analysis of soil is best to use chicken or chicken mature organic fertilizer becouse of the high percentage of phosphorus in the manure
