Quantity-Intensity Relation of Potassium in Soils of Selected Land-uses in the Humid Rainforest Agroecology, Southeastern, Nigeria
Application of Q/I concept constitutes a viable approach for the estimation of soil K status and crop K requirements. Soil samples were collected from the 0-15 and 15-30 cm depths of oil palm, cassava, plantain and sycamore land-uses in the humid rainforest agroecology, Southeastern Nigeria and a...

| description | Application of Q/I concept constitutes a viable approach for the estimation of soil K status
and crop K requirements. Soil samples were collected from the 0-15 and 15-30 cm depths of oil
palm, cassava, plantain and sycamore land-uses in the humid rainforest agroecology, Southeastern
Nigeria and analyzed for K forms and Q/I parameters. Data generated for the K forms and the Q/I
parameters were subjected to ANOVA and means separated using LSD at 5% probability level.
Also, the K forms were correlated with soil properties and K Q/I parameters and equally amongst
themselves using correlation analysis. Potassium forms significantly (LSD 0.05) decreased as total
> structural > available > exchangeable > non-exchangeable > solution K. The K Q/I parameters
varied significantly (LSD0.05) according to land-uses and soil depths and ranged between 1.16-2.03

most K forms and soil properties and between K forms with most soil properties were distinct. The
Q/I concept could be useful for understanding of transformation of K in soil and the prediction of K
fertilizer for sustained crop performance. |
