Usage of glauconite for a higher fertility of degraded soils in the Zhambyl area
The article deals with the use of biostimulator consisting of 20% of glauconite sand in order to increase the fertility of degraded lands. More than 20 micro -and macronutrients contained in it become stimulators of active growth and necessary nutrition for seeds and seedlings. Studies have found that glauconite is a highly effective tool used for seed treatment. It provides a high percentage of germination, rapid growth, plant survival and high yield of up to 2.37 t/ha of alfalfa hay and up to 39.4 t/ha of green mass of African millet. The introduction of phytomelioration based on the use of a biostimulator with a 20% concentration of glauconite sand makes it possible to obtain a stable crop production even on low-fertile soils, does not require large capital investments, both in technical equipment and in the application of mineral fertilizers. These and other positive aspects of phytomelioration make it possible to influence the stabilization of the agricultural production level under the current conditions, and thus to ensure large-scale improvement of agricultural landscapes without introduction of energy-intensive technologies.
