Abstract

Quantity-intensity (Q/I) curves and their parameters are among the methods of determining soil K status. The objectives of this work were to study the correlation of Q/I parameters with K extracted by chemical methods and GARLIC (Allium aestivum) indicies in 8 soils from Hamadan Province. Soil samples were equilibrated with solution containing different POTASSIUM activity ratios. Changes in K concentration in the equilibrium solution were plotted against activity ratio of K, and Q/I parameters were determined. Available K was determined by 13 chemical EXTRACTANTs. The results showed variations in soils with respect to Q/I parameters. Activity ratio at equilibrium (ARk) was significantly correlated with K extracted by 0.1 M BaCl2, 0.05 and 0.1 M HCl, 1 M sodium acetate, 0.025 M H2 SO4, and distilled water. Labile K (ΔK) was significantly correlated with K extracted by 0.1 M BaCl2, citric acid + stroncium chloride, Mehlich 1, 0.05 and 0.1 M HCl, 1 M sodium acetate, 0.025 H2SO4 and distilled water. Labile K was significantly correlated with ARk . Slowly exchangeable K was significantly correlated with K extracted by DTPA and NH4OAC. POTASSIUM buffering capacity was significantly correlated with CEC. The results of pot experiment showed that KΔ was significantly correlated with K concentration, relative yield and response and ARk were significantly correlated with K concentration, K uptake, relative yield and plant response. Other Q/I parameters were not significantly correlated with plant indicies. Labile K and ARk critical levels for 90 percent relative yield of GARLIC were 65 mg kg-1 and 10 (mmol L-1)0.5, respectively.
