Organik Malç Uygulamalarının Toprağın Bazı Fiziksel Özellikleri Üzerine Etkileri

Abstract

This study was carried out in order to determine the effect of organic mulch on the soil properties of wheat straw in wheat fields. Turkey's semi-arid climatic conditions in the Eastern Mediterranean Region. In the study, wheat straw in different proportions (0, 300 kg/da, 600 kg/da and 900 kg/da) was applied to the soil surface. The trial was set up with 3 replications according to the randomized blocks trial pattern under field conditions. After the wheat harvest, soil samples were taken from each parcel at a depth of 0-15 cm and analyzed in laboratory. As a result, it has been determined that wheat straw applications, increases the organic matter of the soil depending on the applications. In addition, wheat straw increased the liquid limit, plastic limit, available water content and field capacity of the soils. Depending on the application dose, liquid limit of the soil, plastic limit, available water content and field capacity increase were associated with organic matter. According to the results of statistical analysis, significant differences were found on organic matter, liquid limit, plastic limit, available water content and field Keywords:Wheat straw Soil water content Field capacity Semi arid conditions capacity (P<0,05). It has been concluded that the application of 600 kg/da and 900 kg/da wheat straw in Kahramanmaraş conditions will increase the organic matter in the soil, increase the water capacity suitable for the plant, decrease the surface flow, improve the porosity properties and provide water and air retention balance in the root zone, thus increasing the yield and quality in crop production.

“…Besides it was informed that the easy availability of these wastes according to the regions is important for the continuous production of mushrooms. Kara et al (2021), examined the impacts of organic mulch practice using wheat straw on the physical properties of the soil. As a result of their study, they determined that 600 kg/da and 900 kg/da wheat straw practices increase the organic matter in the soil and increase the yield and quality in plant production.…”

Physical properties of Oriental beech impregnated and coated with some chemicals

“…Similar studies have been carried out in the literature on this subject. Baysal et al [10] investigated some physical properties, such as water uptake of paradise wood treated with various boron compounds and monomer water-repellent substances. In the study; borax, boric acid, and borax and boric acid mixture (7:3; weight: weight) were used as borates; styrene, methyl methacrylate, and a mixture of styrene+methylmethacrylate (7:3; vol:vol) and isocyanate were preferred as water repellents.…”
