Abstract

Istraživanja kemijskih svojstava tla provedena su na oko 20 ha otvorenih površina, na širem području grada Velike Gorice (Velika Kosnica, Črnkovec, Lekneno, Novo i Staro Čiče, Kuče, Donja Lomnica i Lukavec). Prema pedološkoj karti, istraživano područje spada u kategoriju pogodnih i umjereno pogodnih tala za uzgoj povrtnih kultura. U tu svrhu uzeto je 20 prosječnih uzoraka tla iz sloja 0-30 cm s ciljem utvrđivanja fizikalno-kemijskih značajki i biljno hranidbenog kapaciteta tla. Obrađeni su... More osnovni klimatski parametri (oborine i temperatura) za meteorološku postaju Velika Gorica.
Na temelju dobivenih rezultata utvrđeno je kako je tlo šireg područja grada Velike Gorice pogodno za uzgoj povrtnih kultura, ukoliko se prije sadnje i sjetve kultura provede kvalitetna obrada tla, sniženje pH reakcije tla, te kalcizacija i gnojidba tla organskim i mineralnim gnojivima. Potrebno je poraditi na podizanju reakcije tla do vrijednosti pHKCl 5,5-6,5 kod uzoraka Kuče, Staro Čiče i Lukavec. Alkalna tla u uzorcima Velika Kosnica 1, Velika Kosnica 2, Velika Kosnica 3, Lekneno i Donja Lomnica je potrebno tretirati fiziološki kiselim gnojivima. Zbog kompleksnog utjecaja humusa na ukupnu plodnost tla predlaže se gnojidba tla stajskim gnojem na svim površinama. Kako se radi o tlima različito opskrbljenim biljci pristupačnim fosforom i kalijem nije moguća jedinstvena gnojidba, nego smo gnojidbu prilagodili kategorijama opskrbljenosti. Površine koje su slabo opskrbljene fosforom, a dobro opskrbljene kalijem treba pognojiti s 700 kg/ha NPK 10-30-20. Površine koje su slabo i umjereno opskrbljene fosforom, a bogato i vrlo bogato opskrbljene kalijem treba pognojiti samo pojedinačnim fosfornim gnojivima. Ukoliko se koristi superfosfat, gnojidbu treba provesti s 800 kg/ha superfosfata, ako je triplex 400 kg/ha, a MAP-a 350 kg/ha. Površine dobro i bogato opskrbljene fosforom te bogato i vrlo bogato opskrbljene kalijem nije potrebno gnojiti prije sjetve, odnosno sadnje presadnica. Gnojidbu dušičnim gnojivima potrebno je provesti nakon sjetve, odnosno sadnje presadnica s 200 kg/ha 27%-tnog KAN-a. Less

Abstract (english)

Research of soils chemical properties were carried out on approximately 20 hectares of open space, in the city of Velike Gorice (Velika Kosnica, Ĉrnkovec, Lekneno, Novo i Staro Ĉiĉe, Kuĉe, Donja Lomnica i Lukavec). According to the soil map, study area falls into the category of suitable and moderately suitable soils for growing vegetable crops. For that purpose 20 average soil samples from 0-30 cm layer was taken to determine the physico-chemical properties and plant nutrition capacity... More of the soil. The basic climatic parameters (precipitation and temperature) from the meteorological station in Velika Gorica were analyzed.
Based on the results it was found that the soil of the wider area of Velika Gorica is suitable for the cultivation of vegetable crops, but before planting and sowing crops, soil has to be quality tilled, pH reaction must be reduced, soil also has to be limed and fertilized with organic and mineral fertilizers. For samples Kuĉe, Staro Ĉiĉe and Lukavec it is necessary to work on raising the soils pH reaction values to 5,5-6,5 pHKCl. Alkaline soil in samples Velika Kosnica 1, Velika Kosnica 2, Velika Kosnica 3, Lekneno and Donja Lomnica have to be treated with physiological acidic fertilizer. Due to the complex impact of humus in the overall soil fertility it is proposed to fertilizing the soil with manure on all surfaces. Because availability of phosphorus and potassium in soils are different, fertilization cannot be unique; we had to adjust fertilization to match categories of supply. Surfaces that are poorly supplied with phosphorus and well supplied with potassium, should be fertilized with 700 kg/ha of NPK 10-30-20. Surfaces that are slightly and moderately supplied with phosphorus, rich and very rich supplied with potassium should only be fertilized with individual phosphorus fertilizers. Fertilizing should be carried out with 800 kg/ha if superphosphate is used, 400 kg/ha if triplex is used and 350 kg/ha in case of MAP. Surfaces well and richly supplied with phosphorus and rich and very rich supplied with potassium don't have to be fertilized before sowing or planting seedlings. Fertilization with nitrogen fertilizers should be carried out after sowing or planting seedlings with 200 kg/ha of 27 % strength KAN. Less
