Abstract

Tlo je površinski, rahli sloj Zemljine kore te ima svoja kemijska, fizikalna i biološka svojstva koja ga ujedno čine i nositeljem mnogih funkcija neophodnih za biljni i životinjski svijet. Nastalo je kao rezultat pedogenetskih čimbenika i procesa, a sastavljeno je od vode, zraka, organske tvari i čestica minerala od kojih su najviše zastupljeni aluminij, silicij, željezo, ugljik, kisik i dušik. U prirodi postoje različite vrste tla koje su klasificirane prema zajedničkim svojstvima koja su morfološki vidljiva i mjerljiva kao što je boja, tekstura i struktura. Klasifikacija tala Hrvatske počinje podjelom na 4 odjela koji se zatim dijele na klase, a klase na tipove. Odjeli se temelje na kvaliteti vode i načinu vlaženja te stoga postoje automorfna, hidromorfna , halomorfna i subakvalna tla. Praćenje stanja zemljišta temelji se na analizi tla i propisano je pravilnikom, a kakvoća kao i zahtjevi za korištenje zemljišta moraju biti kvantitativno opisani, odnosno mjerljivi. Stoga se kakvoća tla temelji na analizi uzoraka tla sa svrhom određivanja pojedinih pokazatelja kakvoće. Kakvoća tla ovisi prvenstveno o kemijskim pokazateljima odnosno o pH vrijednosti, humusu, postotku opskrbljenosti dušikom, fosforom, kalijem, fiziološki aktivnim vapnom te o hidrolitičkoj kiselosti. Uzorkovanje tla provedeno je na 24 lokacije u Varaždinskoj županiji te su analizirani pHH2O vrijednost, pHKCl vrijednost, humus, ukupni dušik (N), fosfor (V) oksid (P2O5), kalijev oksid (K2O), ukupni karbonati te hidrolitička kiselost.

Abstract (english)

Soil is the loose upper layer of the Earth's crust. Its chemical, physical and biological properties make it essential for the functioning of flora and fauna. It was formed as a result of pedogenetic factors and processes and it consists of water, air, organic matter and mineral particles, mostly aluminium, silicon, iron, carbon, oxygen and nitrogen. In nature, there are different types of soil that are classified according to common properties that are morphologically visible and measurable such as colour, texture and structure. In Croatia, soil is divided into 4 departments which are then divided into classes and classes are divided into types. The departments are based on water quality and wetting method and therefore there are automorphic, hydromorphic, holomorphic and subaquatic soils. Monitoring the condition of the land is based on the analysis of soil and it is prescribed by regulations. The quality as well as the requirements for the use of land must be quantitatively described, i.e. measurable. Therefore, soil quality is based on the analysis of soil samples with the purpose of determining individual quality indicators. Soil quality depends primarily on chemical indicators such as pH value, humus, the percentage of nitrogen, phosphorus, potassium, physiologically active lime and hydrolytic acidity. Soil sampling was carried out at 24 locations in Varaždin County and pHH2O value, pHKCl value, humus, total nitrogen (N), phosphorus (V) oxide (P2O5), potassium oxide (K2O), total carbonates and hydrolytic acidity were analysed.
