Vpliv hlevskega gnoja na neto mineralizacijo dušika in na izotopsko frakcionacijo dušika v rjavih tleh : diplomska naloga = The influence of farmyard manure on neto nitrogen mineralization and on isotopic fractionation of nitrogen in brown soil : graduation thesisBogataj, TatjanaTalni profil Sorškega polja smo rekonstruirali v 50 cm visoke kolone (Ø 15 cm) in v laboratoriju inkubirali pri konstantni T=17°C 116 dni. V zgornjih 10 cm tal smo zmešali hlevski gnoj (HG) ali ... kalcijev amon nitrat (CAN). Opazovali smo: 6 aerobno inkubiranih variant z 20 t/ha HG=A 20, 40 t/ha HG= A 40, 80 t/ha HG = A 80, 140 kg KAN-a = A 140, 40 t/ha HG + 140 kg KAN-a = A 40 + 140 in negnojeno kontrolo = A 0 ter 2 anaerobno inkubirani varianti s 40 t/ha HG +140 kg KAN-a = AN 40 + 140 in negnojeno kontrolo = AN 0. Mineralizacijo N smo določali s ponavljajočim izpiranjem kolon z deionizirano vodo in/ali s perkolati, ki smo jih zbirali (dan 0, 1, 3, 7, 14, 21, 35, 56, 86, 116). V perkolatih smo določali mineralni dušik in 15N. Prvih 14 dni je prihajalo do nihanja mineralnega N. Dodatek gnojila (HG ali KAN) je povečal nihanje, verjetno zaradi povečanja koncentracije Nmin znotraj kolon na začetku poskusa.Pogosto prelivanje je lahko vzrok izgubam z denitrifikacijo (porast 15N 7 in dan). HG v primerjavi z KAN-om upočasni neto mineralizacijo za 21 dni. 56 dan se neto mineralizacija znatno poveča. Anaerobni pogoji povzročijo velik porast 15N (do 10-krat v primerjavi z aerobnimi pogoji) iz česar sklepamo na izgube dušika z denitrifikacijo. Gnojenje poveča 15N v primerjavi s kontrolo (56 dan je 15N: AN 40 + 140 = +54; AN 0 = +18).Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [T.
