Potassium forms in bris soils (Jambu Soil Series)
The BRIS soils are soils having nutrient deficiency, weakly structured, low water retention capacity, too sandy and limited ability to support plant growth and have a relatively high soil temperature. Due to their sandy nature, leaching process occur easily, leading to the low interact of K in soil...

| description | The BRIS soils are soils having nutrient deficiency, weakly structured, low water retention capacity, too sandy and limited ability to support plant growth and have a relatively high soil temperature. Due to their sandy nature, leaching process occur easily, leading to the low interact of K in soil matrix. The objectives of the study were to determine the different form of K which include the water soluble K, exchangeable K and, and total K, and also to determine the quantity-intensity relationship of potassium. All three forms of K showed that the status of K in sandy soils vary with different depth. The surface soil gave higher results compared to the lower horizons, and this is attributed to the high amount of organic matter content. The quantity-intensity (Q/I) relationship of K data also showed that surface soils gave higher result in their supply power of K. The overall results show slight irregularity among horizons and this is due to the fact that BRIS soils are formed through series of marine sand deposition thousands of years ago. The surface soil of 0-15 cm depth exhibited the higher result in all K forms and K supplying power but is still deficient in K and is insufficient for plant growth. |
