The objective of this study was to evaluate the fixation of ammonium in the soils of Tokat region to find out the important factors influencing them. For this purpose 12 representative soil samples were collected from different Great Soil Groups in the region. | Tr.

For this purpose 12 representative soil samples were collected from different Great Soil Groups in the region. The amount of ammonium fixed naturally in the samples was found NH4-N/100 g. soil). between ppm ammonium ( me The amounts of ammonium fixed by the soils where increasing amounts of ammonium applied were found between . There was a significant effect from application of potassium to the soils on the fixation of ammonium. Potassium applied before ammonium decreased the ammonium fixation in all soils, but when it was applied with it increased the ammonium fixation in other soils except in Ustifluvent 1-2, Ustorthent 2 and Haplustalf 1-2. ammonium Tokat Bölgesi Büyük Toprak Gruplarında Amonyum Fiksasyonu ve Fiksasyonu Etkileyen Bazı Faktörler I. Amonyum Fiksasyonuna Potasyumun Etkisi Özet: Bu çalışmanın amacı, Tokat bölgesi topraklarında amonyum fiksasyonunu değerlendirmek ve bunu etkileyen önemli faktörleri bulmaktır. Bu amaçla 12 toprak örneği bölgedeki farklı büyük toprak gruplarından alınmıştır. Örneklerde doğal olarak fikse edilen amonyum miktarı ppm amonyum ( me NH4-N /100 g. toprak) arasında bulunmuştur. Artan miktarlarda uygulanan amonyumun topraklar tarafından fikse edilen miktarı % arasındadır. .
