Utilizing alumina Al-P to improve plant quality
We have developed a novel alumina-buffered P fertilizer (Al-P) which allows controlled, slow release of P into the potting medium throughout the life of the plant. As the plant takes up P, more P is released from the fertilizer. Thus, adequate, but not excessive, P is always available to provide optimum nutrition for the growing plant.
