Because of their controlled-release properties, phosphate rocks (PRs) are ideally suited for long-term crops such as permanent pastures and plantation crops. In very acidic soils, they may be effective even on seasonal crops. On long-term crops, a time lag is likely between the time of application of PR and its adequate availability to plants. The time lag can, however, be shortened by ...
