Some aspects of agroecological assessment of soils on the development of economic conditions of the Lankaran lowland of Azerbaijan

Abstract

Agroecologically evaluating of the soils under the perennial plantings (citrus and tea plantations) in the humid subtropic climate condition if the Lankaran Lowland has been performed. Unlike the traditional comparative evaluation, besides the soil para-meters, the environment indices are also used. The main and open scales of the soils spread under the citrus and tea plantations have been built, the average calculation scores and comparative valuable coefficients have been found. A state of the perennial plantings (citrus and tea plantations) has been analyzed under the humid subtropic climate condition, decrease of the tea planta-tions area from 135000 hectares to 600 hectares has been indicated. Agroecologically evaluation of the soils under the perennial plantings was fulfilled. Unlike the traditional comparative assessment, The environment indices (rainfalls amount, Md, Σ T > 10 °C, BIP) beside the soil indications (humus, Ph, > 0.25 mm aggregates quantity, bulky weight) are used. At this time the correction coefficients of psevdopodzol which is character for the zone are used: weak psevdopodzolic-1.0; mean psevdopodzolic-0.80; strong psevdopodzolic-0.60; The agroecological scores of the soils under the perennial plantings (citrus and tea plantations) in the humid subtropical climate condition got the following values: weak psevdopodzalic yellow-forest-96 scores; mean psevdopodzalic yellow-forest -77 scores; weak psevdopodzalic yellow-95 scores, mean psevdopodzalic yellow-75 scores; strong psevdopodzalic yellow-58 scores; psevdopodzalic yellow-gleyey-93 scores; yellow-gleyey-91 scores; dark yellow meadow-100 scores; ordinary yellow-meadow-66 scores, bright yellow-meadow 56 scores.
