The soil cover of Adjara is particularly diverse. Its analogue is almost never found in other regions of Georgia. Typical chernozems are widespread in coastal areas. It is the basis of the best environment for the development of subtropical crops (tea, citrus, tungo, laurel and others). Depending on the height above sea level, red soils pass into yellow-brown, and then into forest burozems, which have a relative distribution. Loamy soils under beech forests are characterized by typical properties. Signs of narrowing are observed in the soils of pine-coniferous and coniferous forests.

In the present article, the agroecological features and chemical composition of red earth and yellow earth soils of the coastal humid subtropical zone are studied. For the study, we took three test objects – village on the sea coast Makhvilauri, village near the sea Gonio and village 5 km away from the sea Akhalsofeli. The following components were determined in the soil taken from citrus plantations: suspension pH, exchangeable acidity, mobile phosphorus, exchangeable potassium, The sum of absorbed bases, calcium and magnesium, carbonization, salinity, mechanical composition, hydrolytic nitrogen, humus. The specified territory is dominated by subtropical narrowed or red earth - narrowed soils, so there was no significant difference in the chemical composition of the soil of the test objects.
