How to increase phosphorus use efficiency in calcareous soil?

Answer 1

One way is to use Phosphate solubilisers for releasing locked up P from soil. P enriched/ compost or higher P content organic manures (bone dust) can be used if available. In dairy farms, losses has to checked by using liming material in the litter as a trap. In agricultural land P application has to be made in bands and obviously use VAM formulation so that it can facilitate P to plants.
