Abstract

Tlo predstavlja rahli, površinski dio Zemljine kore koji nastaje trošenjem svih
vrsta stijena, a odlikuje se nizom karakterističnih svojstava poput morfologije, mehaničke
građe, kemijskog sastava, kao i fizikalnih, kemijskih i bioloških svojstava. Kako bi tlo
bilo plodno i kako bi poljoprivredne kulture bile uspješno uzgajane potrebno je provoditi
kalcizaciju, zajedno s gnojidbom i obradom tla. Cilj ovog istraživanja bio je utvrditi
značajke tala na vrbovečkom području, s naglaskom na kemijska... More svojstva i utvrditi koja
su dominantna ograničenja i preporuke za njihovo otklanjanje. Istraživanje je provedeno
na pseudogleju obrončanom pod poljoprivrednom proizvodnjom tijekom 2016. godine.
Uzorci su prikupljani sondom, a ukupno je uzeto 35 uzoraka do dubine od 30 cm. U
uzorcima je određen pH (HRN ISO 10390:2005), količina humusa (metoda po Tjurinu
JDPZ, 1966.), hidrolitski aciditet i fiziološka hraniva K2O i P2O5 (AL – metoda JDPZ,
1966.). Rezultati pokazuju da je reakcija tla kisela i jako kisela u većini uzoraka (pHKCl=
4,07-5,88). Sadržaj humusa je u prosjeku dobar, a varira od 1,73% do 4,97%.
Prema hidrolitskom aciditetu (9-28,8 mmolekv.H+/100g tla) na većini je tala potrebna
umjerena doza materijala za kalcizaciju. Opskrbljenost fiziološki aktivnim fosforom je u
prosjeku dobra, a kreće se od 5,3 do 27,58 mg P2O5/100g tla. Opskrbljenost kalijem je
također u prosjeku dobra i kreće se od 7,4 do više od 40 mg K2O/100g tla. Iz rezultata se
može zaključiti da način korištenja utječe na pH tla, količinu humusa i opskrbljenost
hranivima. Less

Abstract (english)

Soil is the slight surface part of Earth crust which originate from weathering of all
kinds of rocks, and is characterized by series of characteristics such as morphology,
mechanical structure, chemical content, as well as physical, chemical and biological
characteristics. For soil fertilty and succesful cultivation of crop plant, soil needs to be
calcificated along with fertizilazation and tillage. The aim of this study was to determine
the characteristics of land on the Vrbovec territory,... More with an accent on the chemical
properties and determination of the dominant limitations and recommendations for their
removal. The research was conducted on arable pseudogley. Soil samples were collected
by probe, and a total od 35 samples were taken to a depth of 30 cm. In the samples were
determined pH (HRN ISO 10390:2005), humus content (method by Tjurin JDPZ, 1966.),
exchangeable acidity and phsyiologically active K2O and P2O5 (AL – method JDPZ,
1966.). The results show that soil reaction is acidic and very acidic in the most of the
samples (pH-KCl= 5,88-4,07). The average of humus content is good, and it varies from
1,73% to 4,97%. According to the exchangeable acidity (9-28,8 mmolekv.H+/100g soil)
most of the samples needs moderate dose of liming materials. The supply of
physiologically active phosphorus is in average good and ranges from 5,3 to 27,58 mg
P2O5/100g soil. Potassium supply is also good in average and ranges from 7,4 to more
than 40 mg K2O/100g soil. From the results it can be concluded that land use affects soil
pH, humus content and nutrient supplies. Less
