The effect of long-term organic and mineral fertilization on soil air conductivity and some physical properties

In this thesis study, a long-term (1996-2020) crop grown twice a year in Çukurova conditions soil air conductivity and physical properties of 5 different organic and inorganic fertilization methods in the experimental field. effects on its properties were investigated. Fertilizer applications in this trial; control, mineral fertilizer, barnyard manure, compost and mycorrhiza-infused compost. At depths of 0-15 and 15-30 cm in a total of 15 plots organic matter, bulk weight, hydraulic conductivity, water holding capacity, porosity, aggregate stability and air conductivity was determined. In line with the analyzes made, the organic matter ratio was determined in each barnyard manure application. increased at two depths. Volume weight measurement at 0-15 cm in all fertilization applications 15-30 cm depth of mineral fertilizer, control and mycorrhiza-infused compost while giving results close to each other applications came to the fore. In the measurement of aggregate stability, barn manure application at both depths It came to the fore with an increase of 34%. Values close to each other in surface soil in total porosity has given. On the other hand, microporosity and macroporosity differed. For microporosity In the analysis, barnyard manure came to the fore, while mineral fertilizer and mycorrhiza inoculated in macro porosity. compost applications gave better results. In subsurface soil, total porosity and macro While the application of barn manure increased in porosity, the values in microporousness were close to each other. was not found to be significant. Field capacity, wilting point and available water are measured by volume. In the analyzes, while the application of barn manure at 0-15 cm was found to be significant by increasing, the values at 15-30 cm were close to each other and not found significant. The highest saturated hydraulic conductivity value is at 0-15 cm It was recorded as 0.50 cm.h and 0.47 cm.h in compost and barnyard manure application. If at 15-30 cm gave values close to each other. In the air conductivity measurements, which is the aim of the thesis, the surface soil compost application was found to be statistically significant. This application was followed by barn manure application. has done. Under the surface, compost and barnyard manure application showed very close values to each other.The results of the study were carried out to improve the physical properties of the soil instead of inorganic applications. showed that organic fertilizers such as barn manure and compost can be preferred.
