The effect of land use on phosphorus dynamics in golf course soil | Vpliv rabe tal na dinamiko fosforja v tleh golfišč

English. Although, it is usually considered that P applied in fertilizers is taken up by crops or immobilized in the soil, and therefore P losses from agro systems is negligible; recent research indicates that significant P leaching out of the root zone, can occur where certain combinations of land use practice, soil properties and climate condition exist. Therefore special attention was given to dynamics of total P (TP) and plant available P in golf course soils. A field study was carried out to assess how different environmental condition and management practices affect dynamics of TP and plant available P in soil. The proportions of plant available P and TP in the golf rough significantly correlated with precipitation. Since no relationship between precipitation and the P dynamics in soil on the greens and fairways was observed.

Slovenian. Res je, da se dodani P z gnojenjem porabi za prehrano rastlin ali pa se v procesu imobilizacije močno veže na talne delce, vendar so novejše raziskave pokazale, da se pri določeni kombinaciji rabe zemljišč, lastnosti tal in klimatskih pogojev tudi P lahko izpira v globlje plasti tal. Zaradi spoznanja novejših raziskav o izpiranju P v globlje plasti tal smo v naši raziskavi posebno pozornost namenili dinamiki celokupnega P in rastlinam dostopnega P v tleh igrišč za golf. Z terensko raziskavo smo želeli oceniti, kako različni okoljski dejavniki in raba tal vplivajo na dinamiko celokupnega P in rastlinam dostopnega P v tleh. Rezultati raziskave so pokazali, da obstaja značilna povezava med padavinami in vsebnostjo rastlinam dostopnega P ter celokupnega P v tleh ledine na igrišču za golf. Medtem ko, povezava med padavinami in dinamiko P v tleh zelenic in čistin igrišč za golf ni bila ugotovljena.
