The blueberry varieties that are widespread in the world today do not have the desired effect on all
types of soil.
Blueberry is a perennial berry culture. Its wild form is less demanding to environmental conditions,
though, nowadays, the world-wide spread cultures do not provide the expected effect on all types of soil.
Blueberry cultivation requires an acidic soil that is procured with a moisture of a light mechanical
composition. It is very actual to proceed with the preliminary study of soil-climatic conditions of those areas
where blueberry culture must be cultivated for industrial purposes.
Yellow soil is the most qualitatively distinctive soil type in the humid subtropical zone of Georgia.
Soil-forming rocks mostly in the hillocky zone are sedimentary rocks of the third age - shales, sandstones,
conglomerates. Clay-shales and conglomerates of Jurassic age are observed in the Okriba basin. The typical
(Natural) profile of yellow soil consists of the following genesis horizons, Ao-AB-B-BC-C. Yellow soils are
distributed in Tskaltubo, Zestaponi, Kharagauli, Khoni, Samtredia, Bagdadi, Terjola, Vani, and Tkibuli
municipalities (Imereti region)
The soil bio-climatic conditions of the agro-ecological environment meet the requirements for the
cultivation of blueberries together with other berry cultures, based on agro-technological activities for
blueberry industrial demonstration plots in Tskaltubo, village Gumbri, and Imereti yellow soil zones.
The experiment covered: a) Field and b) Laboratory researches. Soil agro-ecological environment
for blueberry culture. Blueberry culture towards soil bio-climatic conditions is characterized by the
following requirements: Physical-mechanical properties of the soil ( 0–20cm in the soil layer). It is well
adapted (20–40cm) to light loamy, loamy, and heavy loamy soil types implying appropriate agrotechnological activities.
The yellow soil according to our studies is heavy loamy, it is urgent to be cultivated, which implies the
following activities: pre-sowing (Green manure), deep tillage, well-shredding, and landscaping (Preparation
for melioration)
Defending agro-technological rules is very important.
Blueberry cultures cannot tolerate excessive moisture, but it requires irrigation for perfect
development. A drip system is recommended from agro melioration technologies of irrigation rules. Research
proves that the Imereti region is the best for blueberry cultivation.
