The secret to success rests in your ability to precisely meter, control and deliver nutrients and pest control solutions.Last season we spent a great deal of time studying the impact that our fertigation plan had on our hops (based on soil analysis) a task made immeasurably easier thanks to our Dosatron International - USA, North and Central America and its ability to precisely control the delivery of nutrients direct to our root system. What we lacked was a similarly robust and accurate method for applying foliar applications to the above ground bio-mass.
