We know you need to get the most out of your fertilizer.

So we made RhizoSorb.

 

Inspired by 13 peer-reviewed papers and over 23 years of research at Penn State University, Phospholutions develops soil amendments that reduce chemical inputs, improve plant and soil quality, and optimize fertilizer use.

Remembering our roots

Rick

Over two years ago, 

Rick Pagett was on of the first superintendents willing to work with Phospholutions to develop our technology for golf industry. He saw potential in RhizoSorb and it's application in the turf industry. Because of his support, commitment to environmental stewardship, and interest in research, RhizoSorb has become a reality. We've worked to create better roots on his course, but he helped to establish ours.

Thank you Rick!
