Residual Effect of Potassium Fertilizer on Potato in Western Siberia
This long-term field experiment revealed that the residual effect of K fertilization on potato yield may last 4 to 5 years depending on the prior application rates. During this period, the decline in exchangeable and non-exchangeable soil K was considerably larger than crop K removal.
