| dc.description | Abundant rainfall in the Central Brazilian Amazon, and the naturally low cation exchange capacities of the regions' s clayey Oxisols, promote the rapid leaching of potassium from the soils. Native soil K reserves can be expected to be small, since clay mineralogy is predominantly kaolinitic. These conditions suggest that crop production on these soils will require continual K fertilization, and that management systems should be considered to minimize K losses. The objectives of this project were 1) to establish K response curves and soil-test calibration data for the main annual crops cultivated in the region, and 2) to determine whether split applications would improve the efficiency of K fertilization. | eng |
