Abstract

One of the most intensive fertilizers in our country is Potassium and Glauconite sand stone may be one of the alternatives established of potassium. The present research was conducted with the aim of investigation the effects of glauconitic sandstone used as Potassium fertilizer for canola plants and potential of potassium release and iron toxicity. The plants cultivation was carried out as an completely randomized experiment based on factorial design in growth chamber in the form of pot cultivation in sand culture. The first factor was potassium and in three levels including Hoagland without potassium + glauconitic sandstone powder, Hoagland with potassium and Hoagland without potassium and the second factor was pH of culture medium at two levels of 6 and 5. 7. Potassium was used as potassium nitrate and glauconitic sandstone powder was mixed with washed sand before planting. The results indicated that potassium deficiency in treatment without potassium caused severe reduction in growth traits, content of potassium, soluble protein in aerial organs, soluble sugars, starch and chlorophyll a and total chlorophyll and increased total amino acids. Application of glauconitic by releasing potassium could compensate potassium shortage at plant growth environment so that the plants treated with Hoagland without potassium + Glauconite sand stone powder did not indicated any significant difference in potassium content and many growth traits such as total fresh and dry mass with Hoagland treated with potassium. Iron content of canola root in Hoagland treatment was higher than to two other potassium treatments however, pH reduction from 5. 7 to 6 did not increase iron content of the plants. The reduction of pH of Hoagland and Glauconite treatments decrease of protein, starch and chlorophyll contents and led to plants growth. The results indicated that glauconitic sandstone powder has certain potential to release potassium. Without considering pH of nutrient solution, no toxicity symptom was observed in canola plants following Glauconite sand stone application.
