Abstract :Organic fertilizer is a plant nutrient material which is used for obtaining the requirements of nutrients of plants grown in agricultural production. Organic fertilizers increase the organic matter content by providing nutrients to the soil as well as providing a more favourable growth environment for plants by correcting the physical properties of the soil. Organic fertilizers, mainly nitrogen, phosphorus, potassium, such as many important nutrients are brought to the soil. Chemical fertilizers can be obtained from petroleum products, from rocks and even from organic sources. This type of fertilizer helps plants grow, but there is no contribution to the growth of the soil. This study was conducted in order to compare the effects on soil two synthetic and organic fertilizers derived molasses each pot seedling stage surprise in 500 ml of water 3 times and followed up at 3 week intervals. Experiment 5 was set up in a randomized trial design and plants were grown in greenhouse conditions. At the end of the experiment, physicochemical analyses of potted soil were carried out and the differences between applications were investigated. Accordingly, the contents of organic matter, salt and mineral matter increased in fertilizer applications. In addition, the lowest soil pH was obtained in the application of synthetic fertilizer.
