The following paper considers influence extent of zeolite breed of the Hotynetsky field on indicators of relevant and exchange acidity of the cespitose-podsolic sandy loamy soil in the Nizhny Novgorod Region. A three-year experiment, representing microfield experiment, was started in 2014 in the Borsky District Elitkhoz. Zeolite was brought in the plough-layer once in high doses 3, 6 and 12 t/hectare. During the research (20152017) on allotments the main crops of the region were grown up. The acidity of the soil was estimated on рН indicators, defined from water and salt extracts which were selected during the autumn period after cultural plants harvesting. As a result of the conducted researches positive action of all doses of the studied zeolite on indicators of the acid and main mode of the cespitose-podsolic soil was established. The essential effect was traced already at the minimum dose of material: 12,0% increase of рНwater indicator and 6,3% increase of рНsalt indicator on average during the research time. Application of 6 t/hectare of zeolite breed in the greatest measure promoted reduction of the relevant acidity of the soil by 20%, exchange acidity for 13% and also for 60% to increase in an ionic exchanging of the soil solution system with preservation of the action force during the research time.
