| Abstract: | By using KCl as potassium source and clinoptilotite in Xinjiang as slow-release carrier,adsorption property and slow-release effect of clinoptilotite to potash fertilizer were studied.The relationship between adsorption time,K+ initial concentration and the adsorption quantity was discussesed.Desorb K+ from clinoptilotite slow release fertilizers separately in pH 5 HCl solution and Ca2+,Mg2+ mixed solution with a concentration of 1.6,3.2,6.4,12.8,19.2 and 25.6mmol/L.The results showed that the adsorption ca... |
