Asvarova T.A., Gasanov G.N., Gadzhiev K.M., Bashirov R.R., Gimbatova K.B., Abdulaeva A.S. ON THE NITROGEN BALANCE IN THE SOIL AND VEGETATION COVER OF ARID ECOSYSTEMS IN THE NORTH-WESTERN PRECASPIAN // Arid Ecosystems. 2023. Vol. 29. № 3 (96). P. 36-45. | PDF

In this article we present the results of studies on the accumulation and translocation of phytomass estimated by blocks of plant matter, nitrogen concentration and nitrogen reserves. We estimated the compensation of the nitrogen balance in light chestnut and meadow-chestnut soils and typical solonchaks in the grass ecosystems of the North-Western Precaspian under the conditions of aridization and desertification.

Keywords: nitrogen, nitrogen reserves, nitrogen balance, phytomass accumulation, plant matter blocks, green mass, rags, felt, aridization, desertification.

Financing. The work was carried for the state task of the Caspian Institute of Biological Resources of the Dagestan Federal Research Center of the Russian Academy of Sciences “Monitoring and Forecasting of Soil Cover Dynamics and Bioproductivity of Landscapes of the Northwestern Caspian and Dagestan Part of the Eastern Caucasus”, Section 2, No. AAAA-A20-120062990014-2 “Bioproductivity of Landscapes and Nitrogen and Carbon Balances in Ecosystems Exposed to Natural-Anthropogenic Transformation of the North-Western Caspian Sea”, Topic 2, No. 122032200273-6.
