Abstract
Evaluation of the potential buffering capacity of potassium (PBCk) using the quantity/ intensity (Q/I) concept provides a satisfactory measurement of K availability in soils. The Q/I relationship parameters can be evaluated soil K content (∆K°), the ability of the soil to provide K for plant uptake (ARek ), and also the capacity of the soil to maintain K+ availability. Representative acid sulfate soils in the Central Plain of Thailand including Ayutthaya soil series (Ay1 and Ay2), Sena soil series (Se1 and Se2), and Rangsit soil series (Rs1 and Rs2) were collected to determine various forms of K contents and PBCk . The result showed that most of the studied soils contained a high level of available K (water soluble K + exchangeable K) except for Se1 and Se2 which showed a moderate level of available K. The PBCk values of the studied soils ranged from 27.5–105 (cmol kg–1)/(mol L–1) 1/2 and most soils showed the low to moderate level of ability to maintain K+ availability. The PBCk values of studied soils positively correlated with soil pH (R2 = 0.33, P < 0.05). The available K (∆K°) values were mainly negative, indicating soil K+ can be easily released for plant uptake when adding K fertilizers to the studied soils. The activity ratio of soil K+ (ARke) of most acid sulfate soils ranged from 0.001 to 0.01 (mol L–1)1/2, indicating that most of soil K+ content was mainly adsorbed on the exchange sites of clay mineral’s edges, and such soil K+ would moderately easily release for plant uptake.
