Leonardite is one of the organic fertilizer that used in development of soil characteristics and hence increase of yield. In this study the effects of different levels of leonardite were determined on some soil properties in irrigable conditions to wheat plant. The study was carried out between the years of 2009- 2012 in the research area of GAP International Agricultural Research and Training Center as randomized complete blocks design with four replications. In this study six different levels at leonardite (0, 50, 100, 150, 200, 250 kg da-1) were applied. Organic matter, soil moisture, bulk density and penetration resistance were determined in all plots after harvest. At the end of the study different levels of leonardite has no effect on organic matter, soil moisture, bulk density in soil and has effect on penetration resistance. Soil penetration resistance was decreased with leonardite application.
