Ecological Assessment of the Cucumber Plants Reaction to the Use of Production Waste and Natural Minerals in the Composition of Nutrient Soils

Abstract

The article discusses one of the waste management areas – the use of fertilizer properties of chemical compounds that make up various types of production waste. The salt aluminum slag of the Mtsensk metallurgical plant AOOT Non-ferrous Metals and Alloys was chosen as the object of pollution. The presented studies indicate that the presence of macro-and microelements in the composition of slag fertilizers significantly increases the value of these fertilizers and partially solves the problem of complex application of the necessary elements into the soil [10]. The effectiveness was evaluated of the fertilizing properties of the salt screenings of aluminum slag, vermicompost and zeolites when using them as a part of nutrient soils for growing cucumber [8]. An increase in the toxic load for the analyzed period was established [7]. Also, all the studied forms and types of fertilizer nutritional compounds have a physiological effect, increase the growth and development of cucumber plants, product quality, and contribute to plant resistance to adverse environmental conditions and to the production of environmentally friendly products [13]. The effectiveness has been proved of the method of using plant cell juice electrical conductivity to assess the physiological state at different growth phases as a reaction to the fertilizer levels of production waste and natural minerals [9].

Using of immunomodulating substances in optimizing cucumber nutrition in protected soil conditions

“…Biologically active substances can have multifunctional properties: providing plants stress free conditions, adjusting the microclimate conditions, restraining the development of fungal and bacterial diseases of vegetable crops and other negative factors [2,3,4,5]. Compositions based on biologically active substances stimulate the course of physiological processes, the growth and development of plants, are able to increase the adaptive ability to adverse environmental factors, increase the immunity of the plant organism and resistance to phytopathogens [6,7,8].…”
