The work purpose - to establish laws of dynamics of indicators of mobile nutrients and a humus in dark-chestnut sewaged soil at various anthropogenous charges, to develop methods of utilisation of fertilizers which provide preservation of fertility of irrigated lands. A research method - field, laboratory, statistical. Results of researches of dynamics of a humus and mobile nutrients (NРК) in dark-chestnut sewaged soil are resulted at regular fertilization; the basic laws of changes of indicators of soil fertility in the conditions of a long irrigation are defined; organo-mineral fertilizer systems of crops which provide preservation of fertility and rational utilization of fertilizers are offered.
