Abstract: A system includes a first chamber configured to hold a liquid and a second chamber configured to hold the particles. A first pump transfers the particles from the second chamber to a third chamber. A first valve during a first time period regulates the delivery of the liquid into the third chamber through a first opening. A second opening directs 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 first pump to transfer the 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 particles to be directed through the second opening into the holes.

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.

Abstract: A method for delivering plant seed material to a target placement surface is described. The method comprises utilizing a core material and combining plant seed material with the core material to create a vector. A plurality of vectors are delivered to a target placement surface but a barrier layer of vectors is not created.

Abstract: Plastic bags are continuously formed and filled with sand, soil and gravel to fabricate flexible soft bricks of various shapes and configurations which may be laid on the ground to stabilize sand for growing vegetation or to prevent soil depletion due to water erosion or to grow vegetation in them. Protective housings made of plastic membrane material may be erected in dry or desert regions for growing trees and vegetation. The lower portion of the housing may be located below ground into a trench. Self operating knives are located in the housing to sever the plastic membrane material when the tree grown in the housing has reached a predetermined maturity. Tree planting bullets are provided to facilitate forestation by airplane to land inaccessible regions. The tree seedling is located in supported in an embryonic sack located in a depression formed in the rear portion of the bullet head.

Abstract: A system for control of operational parameters within agricultural implements such as seed planters includes an agricultural work vehicle such as a tractor with an operator's station; an agricultural implement connected to the vehicle; a control subsystem including means for inputting a set point and for providing a control signal, located at the operator's station; a display connected to the control subsystem and located at the operator's station; an actuator connected to the control subsystem and located upon the implement; and a sensor connected to the display and located upon the implement. In one embodiment, the system further includes a source of low pressure air such as a fan, the implement is a seed planter having at least one substantially closed hopper or bin pressurized by the air, the actuator is a fan drive speed control apparatus, and the sensor is a pressure transducer configured to measure air pressure within the bin and connected to both the control subsystem and the display.

Abstract: Gel capsules having a size approximately equal to that of the seed being planted and which contain: (a) an earthworm cocoon having one or more viable eggs; and (b) a material to provide a density to the capsules approximately equal to that of the seed being planted; are mixed with and planted with the seed to introduce earthworms to a field.
