ABSTRACT:
An apparatus for forming holes in ground and for placing hygroscopic particles into the holes is disclosed. The apparatus includes a first chamber configured to hold a liquid and a second chamber configured to hold the hygroscopic particles. A first pressure mechanism maintains the liquid in the first chamber at a first pressure level, and a second pressure mechanism maintains the hygroscopic particles in the second chamber at a second pressure level. A first valve is operable during a first time period to regulate the delivery of the liquid into a third chamber through a first opening. A second opening is configured to direct jets of liquid from the third chamber during the first time period to form holes in the ground. A second valve is operable during a second time period to regulate the delivery of the hygroscopic particles to the third chamber. The first valve is operable during a third time period to regulate the delivery of the liquid to the third chamber through the first opening causing jets of the hygroscopic particles to be directed through the second opening into the holes.
