Abstract

Rezultati kemijskih analiza tla daju uvid u stanje opskrbljenosti tla biljnim hranivima, a kemijska analiza biljnog materijala (lista) pokazatelj je stupnja opskrbljenosti biljke biljnim hranivima. Analiza tla, posebice analiza biljnog materijala predstavljaju važan pokazatelj i pouzdan su alat u planiranju i sastavljanju programa gnojidbe drvenastih kultura. U suvremenoj poljoprivrednoj proizvodnji kemijska analiza biljnog materijala ima izuzetno značajnu i nezamjenjivu ulogu. U radu se daje prikaz vremena, načina i biljnih dijelova (vegetativnih i generativnih) koji se uzorkuju za kemijske analize, a sve s posebnim naglaskom na drvenaste kulture. Daju se i referentne vrijednosti biogenih elemenata s iskazom gornjih i donjih koncentracija optimalnih vrijednosti istih u listu. Također, daje se i prikaz mogućih pogrešaka u praksi, te stručno-znanstvene dvojbe kad su u pitanju uzorkovanje, priprema uzoraka i kemijska analiza biljnog materijala.

Abstract (english)

The results of chemical analyzes of the soil provide an insight into the state of supply of the soil with plant nutrients, and the chemical analysis of the plant material (leaf) is an indicator of the degree of supply of the plant with plant nutrients. Soil analysis, especially the analysis of plant meterial, represent an important indicator and are a reliable tool in planning and compiling a fertilization program for woody crops. In modern agricultural production, the chemical analysis of plant material has an extremely important and irreplaceable role. The paper describes the time, method and plant parts (vegetative and generative) that are sampled for chemical analysis, all with a special emphasis on woody crops. Reference values of biogenic elements are also given with a statement of the upper and lower concentrations of the optimal values of the same in the leaf. Also, possible errors in practice and professional-scientific doubts are presented when it comes to sampling, sample preparation and chemical analysis of plant material.
