and Agrochemistry named after O.N. Sokolovsky» The purpose. To study alternative approaches to amelioration of acid soils. Methods. Analyticalsynthesizing (research of change of properties of soils under influence of amelioration), comparativeanalytical (comparison of influence of alternative approaches of amelioration of acid soils on their soil parameters), general scientific (system, complex) and calculative. Results. Results of researches of application of calcium containing production wastes and local source of raw materials as improvers upon acid soils are generalized. Characteristics and mechanism of action of biomeliorative influence of cultures-phyto-improvers upon structurally-aggregation state of podzolized soils are resulted. Conclusions. It is determined that the most effective and ecologically safe calcium containing improvers are dolomite, defecate and limestone flux in doses determined according to charts of рН buffering. It is fixed that the most effective structure-creating properties have Lucerne, Sainfoin and Mustard.
