The analysis of a 27-year data package of a long-term field multifactorial experiment using fertilizers (NPK) on tea culture is presented. The paper shows a long-term dynamics of changes in acid-base and nitrogen status of acid brown forest soils due to the load of nitrogen fertilizers, nitrogen balance and yield of plantations. The optimal doses of nitrogen fertilizers are determined, allowing us to achieve a reasonable compromise between economic and environmental feasibility in a multi-year mode of application. It is shown that nitrogen dose 70-90-120-200 kg/ha (for 3-4-7-13 years, respectively) provided a sufficiently high productivity of plantations (including the quality of raw material) while maintaining a medium availability and a neutral balance of nitrogen; agrogenic acidization of soils has not exceeded the allowable average degree, at the same time increasing their potential fertility for tea plants.
