Evaluation of the Agrochemical Effectiveness of Natural Substrates in Greenhouse Conditions
Sara Sadigli 
Abstract. In greenhouses various types of substrates such as coco peat, sawdust, composted bark, peat, compost are used for growing plants. Within the scope of this study, the physicochemical and agrochemical properties of natural used mainly for vegetables and other plants in greenhouses were investigated in detail. The appearance and structure of the substrates used their size, shape, arrangement, and porosity were comparatively investigated. In addition, the acidity of the substrate, the amount of organic matter and nutrients, as well as the cation exchange capacity, salinity, were statistically studied on the substrates. All the data obtained here were calculated in the form of tables and graphs, average, standard, maximum and minimum indicators. As a result, all the calculated data were visually depicted. The results of the study show that, based on the data obtained, the properties of the substrates provide significant recommendations for the correct selection of substrates for vegetable growing, productivity and practical experiments in ensuring ecological sustainability.
