About the project
Relevance Currently, Kazakhstan is faced with the problem of serious deterioration of the state of natural resources and the environment in all the most important environmental indicators. Almost a third of agricultural land is now degraded or under serious threat, and more than 10 million Hectares of potentially arable land have been abandoned in the past. The results of the annual monitoring of irrigated lands conducted by hydrogeological and reclamation expeditions show that currently more than 50% of irrigated lands have varying degrees of salinity and more than 30% are brackish. At the same time, huge volumes of drainage and wastewater generated on irrigated lands and in settlements (up to 10-30%) pollute water sources and worsen the ecological and reclamation situation of irrigated lands and adjacent territories. In general, over the period 1990-2012, the area of irrigated land in the country decreased from 2.5 million hectares to 2.1 million. ha, of which no more than 1.4 million hectares are currently used. More than 100,000 hectares of irrigated land have been withdrawn from agricultural circulation. Biochar is a biofertilizer and a unique soil restorer. The composition of the biochar mainly includes carbon accumulated by burned plants. Biochar is used as an organic fertilizer capable of preserving water and nutrients in the soil, which dramatically increases soil fertility and agricultural productivity. The cultivation of the land for many centuries has led to a deterioration in its quality, the ability of the earth to quickly absorb water has deteriorated. The development of biochar production and application in agriculture and forestry makes it possible to improve land fertility in a short time. Already today, Biochar is one of the most promising types of fertilizer, because when fertilizing the soil, not only new plants grow and develop well, but also this type of fertilizer does not pollute the atmosphere with carbon dioxide. Many scientists call biochar "black gold" for farming. Studies on the study of biochar in Kazakhstan are isolated, they mainly concerned studies on the rehabilitation of soils contaminated with heavy metals by mining and metallurgical enterprises of the city of Ridder in the East Kazakhstan region. The results of the study conducted on fertile dark chestnut soils showed a fairly high efficiency of applying biochar for vegetable crops. Some publications related to the review of the literature of foreign authors on the study of biochar. However, so far, no targeted studies have been conducted to study the effectiveness of biochar for the main field crops of the irrigated zone of Kazakhstan, its reclamation qualities for the restoration of degraded infertile lands in the south and south-east of Kazakhstan, in particular ordinary gray soils with a close occurrence of pebbles, so-called soils, which are characterized by a very low content of organic matter (less than 1%). The role of biochar in changing the degree of greenhouse gas emissions and mitigating the effects of climate change has not been identified. The project is aimed at solving the problems of preserving soil fertility, reducing greenhouse gas emissions and protecting the environment of the irrigated zone of southeastern Kazakhstan. The purpose of the project Development of effective methods to reduce greenhouse gas emissions, preserve and increase soil fertility based on the use of biochar and perennial crops for reclamation of degraded, secondary saline irrigated lands of south-east Kazakhstan Expected and achieved results The results of the project will be published: - 2 (two) articles in peer-reviewed scientific publications in the scientific direction of the project, indexed in the Science Citation Index Expanded of the Web of Science database and having a CiteScore percentile in the Scopus database of at least 50 (fifty); - 1 (one) article in a peer-reviewed foreign or domestic publication recommended by COXON; - A patent application has been filed for a utility model "Method of reclamation of irrigated lands"; - The recommendation "Biochar-technology of cultivation of irrigated crops in the south-east of Kazakhstan" has been developed; In order to spread knowledge, 1 field seminar will be held, a recommendation, an advertising booklet, 2 articles in regional and republican newspapers and magazines, 1 speech on TV will be published. 1 doctoral student and 2 undergraduates have been trained. The field of application is agriculture. The target consumers of biochar technology are farmers, agricultural partnerships of the irrigated zone of the south and south-east of Kazakhstan.

Information for potential users The developed biochar technology can be commercialized for implementation on degraded and infertile lands of farmers in the south and south-east of Kazakhstan. The target consumers of biochar technology are farmers, agricultural associations of the irrigated zone of the south and south-east of Kazakhstan. The implementation of the project to ensure: - improvement of the agrophysical properties of the soil; - reduction of greenhouse gas emissions per unit area by 30-40%; - increase productivity of degraded irrigated soils by 30%; - increase in the utilization rate of mineral fertilizers 20%; - return to agricultural turnover of 20 thousand hectares of irrigated land; - utilization of agricultural and forestry waste for the production of biochar; - development of small and medium-sized enterprises in rural areas for the production of biochar; - creation of additional jobs in rural areas Members of the research group 1.
