Farklı Organik Atık Uygulamasının Toprak Kalitesi Üzerine Etkisinin SMAF Modeli ile Belirlenmesi

Abstract

Soil is an essential resource for terrestrial life. That’s why it is vital to use it without causing any harm to its ecological and economic functions. This current study was carried out to investigate the effect of different organic materials (farmyard manure, vermicompost, leonardite, rose pulp, biochar, biogas waste, seaweed) on soil quality using the SMAF model in Isparta province, which has a semi-arid ecological characteristic. Thirteen soil quality indicators were used to determine the physical, chemical, and biological soil quality of the SMAF model. In this study, twelve indicators were used, which were: bulk density, aggregate stability, available water content, water-filled pore space, organic carbon, pH, electrical conductivity, sodium adsorption ratio, available potassium and phosphorus, microbial biomass carbon, and ßeta-Glucosidase enzyme activity. In general, the applied organic wastes had a positive effect on the quality characteristics of the soils. The lowest quality was determined in the control (50%) and seaweed (51%) applications, while the highest quality increase was determined in the rose pulp application (60%) and vermicompost application (56%). Other applications did not cause significant changes according to SMAF scoring. The most important effects of low quality scores were determined as biological quality indicators. According to the results obtained, organic waste application for sustainable soil management has an important place in increasing the physical, chemical, and biological soil quality properties of agricultural soils, especially in the arid and semi-arid areas of our country, as well as increasing the general soil quality index values.

Soil Physiochemical Properties and Cucumber Productivity Assessment under Organic Fertilization

“…Though the performance of cucumber was signi cant across all organic treatments, poultry dropping demonstrated superiority while cow dung came second and cocoa pod husk was last, which conforms with the nutrient contents of the various organic manures(Yunilasari et al, 2020; Zhao et al, 2021). Poultry dropping had a more signi cant effect on cucumber vegetative growth parameters due to its high nutrient content, which is in line with other studies(Adekiya et al, 2020;Alaboz et al, 2022). The low growth experienced in control shows the porous nature of the sandy soil, which rarely holds nutrients in uptake form by crops(Nkongho et al, 2022b).…”

Tomato varieties superiority assessment under organic and inorganic (granular and foliar) fertilization in sandy clay soil

“…Thus under the experimental setting, the agronomic and phenotypic factors enhance variety growth while the environmental factor was favored by better management (Healy et al, 2017;Ketema and Beyene, 2021). On the other hand, fertilization significantly affects the soil's chemical properties, with poultry manure showcasing prowess in enhancing soil chemical properties (Hasnain et al, 2020;Alaboz et al, 2022). The poultry manure buffered the soil pH positively, which makes more nutrients available, whereas NPK 20:10:10 further dampens the acidic pH under which nutrients like phosphorus are fixed to the metallic ions and become less available (Brunetti et al, 2019).…”

Evaluation of Aggregate Stability Using the Slaking Index Method with Soil Physical Approach in Keduang Sub-Watershed, Indonesia

“…Organic C is one of the fundamental parameters in sustainable agriculture (Alaboz et al, 2022;Rahayu et al, 2024;Romadhon et al, 2024) and plays a role in nutrient availability, improving soil's physical, chemical, and biological properties (Farrasati et al, 2019;Meilani et al, 2023;Smith et al, 2013). The results of organic C analysis show that organic C at the research location is in the very low to medium category (Center for Research and Development of Agricultural Land Resources, 2009).…”
