On September 21, 2017, within the framework of the FORBIO project, an excursion to the site of growing energy willow of the company "UkrAgroEnergo" took place. Plantation area is operated by Ukragroenergo LLC, subsidiary of Ukrteplo group of companies, which implements energy efficiency projects on fossil fuels substitution by such local fuels as wood pellets, briquettes, chips, straw etc. Ukrteplo has replaced more than 50 million cubic meters of natural gas in 16 regions of Ukraine, and converted to solid fuel approximately 100 boiler-houses.
The mother plantations of willow are located at the area of 50 ha in Ivankiv region and were set in 2016 on the lands, which were abandoned 15 years ago, because of unsatisfying soil conditions (sandy, sandy loam soils) and bad economic conditions in the region.
Swedish Salix viminalis L. varieties “Tora”, “Tordis”, “Inger” are grown on the plantation.
The main climate characteristics of the study area are summarized in the table below:
|Average temperature in January||– 6 °С|
|Average temperature in July||+ 19,5 °С|
|Average annual temperature||6,9 °С|
|Average altitude||131 m|
|Annual radiation balance||45 kcal/cm2|
|Moisturizing factor (the ratio of precipitation to evaporation)||1,0-1,2|
|Annual precipitation||550-650 mm|
|Annual air humidity||80%|
Soil analysis showed low fertility rates due to the low level of the following elements: nitrogen (N), potassium (K), calcium (Ca), magnesium (Mg), sulfur (S), zinc (Zn), copper (Cu), boron (B).
Level of pHKCI is 5,20 (acid soil). the level of electroconductivity of soil (EC mS/cm=0,39) is low for growing common food agriculture crops. ДThe field trials of the Salix viminalis L. varieties show that the possible biomass yield of industrial plantation could reach 10 dry tons/hectare/year.
Potential of unused agricultural lands within a radius of 50 km from Ivankov are 21.35 thousand ha.
