Application of a vermicomposter containing biostimulant for pine tapping

Abstract

The issues of biotechnological development of economics have become rather topical in recent years. Scientific papers in the field of environmental economics, namely in the field of the forest sector, are of particular interest. The main component of the forest industry bioeconomics development is the increase in the volume of forest resources management. Rubber tapping (tapping) is the main form of natural resource management of pine plantations. During the analysis of the resources, it was found that the development of an alternative biological stimulant of animal origin for tapping is needed to be developed for its further application, and its efficiency of the maximum pine resin yield should be assessed. A 1% aqueous extract of the vermicomposter of Black Soldier Fly (Hermetia illucens L.) was used as the main active component of the experimental biostimulant. At the test area, where the studies were conducted, trees involved in tapping procedure included ones, on which the stimulant was tested, and those trees, where ordinary tapping was carried out without the use of the stimulant; the latter ones were considered to be a control group. In the course of studies, it was found that the biostimulant based on the vermicomposter of Black Soldier Fly led to the excess of the resin yield per centimetre of face in comparison with the control group. Also, no negative effect of the biostimulant on the pine forest condition was revealed.
