Estimation of potassium (K) concentration in oil palm leaf tissue is
routinely carried out in oil palm plantations to manage fertilizer
application for getting higher fresh fruit bunch (FFB) production. Since K
in plant tissue is not bound to organic complexes and it is extractable by
water, this study was carried out to extract K from oil palm leaf tissue
by water extraction method. The results were compared with other
established methods like 1 normal (N) ammonium acetate (NH
OAc)
extraction, 0.5 N hydrochloric acid (HCl) extraction, and diacid digestion.
The proposed water extraction method consists of shaking of 0.5 g finely
ground oil palm leaf tissue with distilled water at 1:60 ratio [sample-towater
weight (w)/volume (v)] for a period of 20 min in a reciprocating
shaker, filtration of the content, and measurement of K concentration in
filtrate by flame photometer. The results of analysis of 30 oil palm leaf
samples collected from various production systems under different soil
types and management practices for K concentration revealed the close
agreement of water extraction method with other established methods.
The mean value of K extracted by water extraction method was within
1–10% of the K extracted by other established methods. Water-extractable
K was significantly correlated with K extracted by other methods and it
could be predicted by other methods. The values of standard error and
coefficient of variation for K extracted by different methods were very
low, which indicated that the water extraction method was comparable
with other established methods.
