Phytomass of Gray-Brown Soils Forming in Arid Ecosystem of Azerbaijan

Formed in the arid ecosystem of the Greater Caucasus, gray-brown soils were studied in comparison with the phytomass in natural and cultivated cenoses, along with the agrochemical properties of these soils. Comparative study of these indicators on the dominant lands of economically important regions is innovative. Soils of various herbaceous natural cenoses and cover of cultivated cenoses, as well as their agrochemical properties, are important for attracting virgin soils to agriculture. The results show that these lands are suitable for agriculture and high yields.
