The objective of this study was to identify the effect of long-term use of lime, mineral and organic fertilizers on the physico-chemical properties of leached chernozem in the forest-steppe of the Southern Urals. Field experiments were conducted in the instructional farm of the Bashkir Agricultural Research Institute. The terrain is flat. Average annual precipitation varies from 389 to 500 mm. The sum of active temperatures reaches 2180-2230 ° C. The effect of experiment factors was studied in six-field grain-fallow and grain-grass crop rotation fields. The lime rates were calculated according to the total hydrolytic acidity of the soil. The dosage of organic and mineral fertilizers was determined to get the planned yields of crops in the given crop rotation. After liming, the reaction of the soil medium in the arable layer reaches optimal values for crops being pH 5.8-6.0. The amount of exchangeable bases increases from 38-41 to 43-45 mg-eq/100 g of soil. As a result of the complex application of liming, organic and mineral fertilizers, the physico-chemical properties of leached chernozem get close to the optimal parameters for field crop cultivation.
