Abstract

Because of the intensive use of natural resources and increased anthropogenic loads, a tense ecological situation has developed in the Western regions of Kazakhstan. This has led to the necessity of urgent measures among which is enhancing areas for black saxaul forest plantations. Based on the study conducted at Samsk State Institution for Protection of Forests and Wildlife in Mangystau Region the authors of the article have proved that the main methods of tillage impact on the growth and survival rate of black saxaul in the arid conditions of Western Kazakhstan. The article presents the results of the effectiveness for the planting of black saxaul forest plantations with various methods of tillage. It has been known that agrotechnical methods of growing plantations are aimed at improving the water regime of the soil through additional accumulation, conservation and rational use of soil moisture. The system of tillage contributes to the creation of these conditions in many respects. The choice of the optimal method of tillage has had a positive effect on the survival rate and intensity of growth and development of the saxaul plantations.
