The aim of this study is to determine the effect of tomato compost (TC) on some chemical properties of soils. For this purpose, a pot experiment was established in the greenhouse and TC was applied in 4 different doses (TC1-1%, TC2-2%, TC3-4%, TC4-6%) to pots containing 3.5 kg of soil, these doses were also applied with chemical fertilizer (CF) (CF, TC1+CF, TC+CF, TC3+CF, TC4+CF) and then tomato plants were grown. Each applications was applied as 3 replicants. Soil sample used in the experiment has clay loam texture, mid-alkaline pH, salt-free, low in organic matter, in the medium lime, nitrogen content is sufficient level, high content of phosphorus, potassium-sufficient, soodic-free soil, microelements are sufficient level. During the greenhouse experiment, soil samples were taken at the end of 3 different vegetation periods of the tomato plant (first flowering, first harvest, final harvest). According to the results, when the changes in cations in the soil were examined, it was determined that the potassium content of the soil increased, calcium did not show any change in the first flowering period of the tomato plant, increased depending on the doses of the applications in the first harvest period, but decreased in the last harvest period. Potassium and calcium were highest in the soil during the first flowering period. The soil magnesium content increased depending on the applications and doses applied. The highest magnesium concentration in the soil was found during the final harvest period. It was determined that the highest amount of sodium in the soil occurred during the final harvest. Generally, after applications across all three periods, the amount of sodium in the soil increased, while in some applications it remained unchanged or decreased.
