Effects of sulphur and leonardit on phosphor efficiency in greenhouse grown tomato

This study that is being carried out for diminishing the amount of phosphorwhich can?t be dissolved properly in Turkish territory, has examined the interactionsbetween phosphor with the diffrent dosages of leonardit and sulphur substances incultivating tomatoes via using greenhouses. According to these findings -that aredrived from this study- the tomatoes that were grown in the leonardit-intensified soilshave shown better results than the ones in sulphur-intensified soils in terms ofefficiency, largeness of fruit and growth parametres. Whilst, the fruits have attainedhigher records where the plants in the soils which were enriched by leonardit andsulphur having chemicel quality, SCKM and sulphur-applied soils regarding totitrated acidics, in the sulphur-applied parts with lack of substance C , the statisticalvalues were observed quite lower. On the other hand, sulphur has been morepowerful than leonardit in terms of the decreasing soil pH.
