20.500.12556/DKUM-38942 DUŠIK V PRSTI V OBČINI GORNJA RADGONA NITROGEN IN SOIL IN TEH MUNICIPALITY GORNJA RADGONA Dušikove spojine so glavne hranilne snovi, ki so za rast rastlin nujne. Ker pa je dušika v tleh pri povečani pridelavi hrane pogosto premalo, se dodaja v obliki gnojil. Ob preveliki koncentraciji dušika v prsti se ta v obliki nitratov spira v podtalnico. V občini Gornja Radgona je glavni vir onesnaževanja tal in posledično vode kmetijska dejavnost. Parametri, značilni za onesnaževanje, ki izvirajo iz kmetijske dejavnosti, so nitrati, amonij, fosfati, kalij in pesticidi. V nalogi se je z analiziranjem prsti ugotavljalo, katere kmetijsko rabljene prsti na območju občine Gornja Radgona imajo večje vsebnosti dušikovih spojin. Ugotovilo se je, da so z dušikom bolj obremenjene kmetijsko rabljene prsti, v največji meri njiva in vinograd; da ima občina Gornja Radgona težave s preobremenjenostjo tal z dušikovimi spojinami, kar dokazujejo analize tal in vode; da je vsebnost dušikovih spojin v tleh zelo odvisna od klime in vegetacijske dobe in da prevelike koncentracije dušika v tleh onesnažujejo talno vodo z nitrati. Nitrogen compounds are the main nutritional substances that are needed for a plant to grow. With increased crop maintenance there is usually too little nitrogen in the soil, so fertilizers need to be added. Nitrogen in the form of nitrates is ringed into the groundwater when its concentration in the soil is too high. In the municipality of Gornja Radgona the agricultural activity is the main source of soil and water pollution. For agricultural activity, nitrates, ammonium, phosphates, potassium and pesticides are the main parameters of pollution. In this diploma paper we analyzed soil and tried to find out which agriculturally used soils on the territory of Gornja Radgona municipality have higher content of nitrogen compounds. We found out that agriculturally used soils, especially fields and vineyards, have higher contents of nitrogen; the municipality of Gornja Radgona has problems with soil pollution by nitrogen compounds which is proved by soil and water analysis; the content of nitrogen compounds in soil very much depends on climate and vegetation period and too high nitrogen concentration in the soil pollutes the ground water with nitrates. dušik nitrat nitrit amonij občina Gornja Radgona nitrogen nitrate nitrite ammonium Gornja Radgona municipality true true false [M.
