Abstract: A protective body/cover (1) to be placed over water/air openings on underground pipes (2). The cover is two-legged and has openings at two opposite ends to permit a pipe (2) to be passed through. Water from openings in the pipe moves towards shaped walls/projections (3), which lead the water to drip (4) through air (10) and fall to the ground (5), approximately directly under the pipe (2). The side walls on the bottom part of the cover have plates/feet (6) which prevent the pipe from sinking down into the ground. At the ends of the protective body/cover (1) there are provided slots or holes (8) with inserted pins/plates (9) which secure the pipe (2) and prevent it from being pushed down. Under the cover there will be formed an air-filled space (10) through which the water drips. Interior vertical walls (7) in the lower part of the cover (1) will be kept dry on the inside and prevent the plants' roots from growing up the wall in their search for the water source (4).

Abstract: A root zone warming system (10) for an athletic field of natural turf (11) supplies positive pressurization to the root zone via a piping network (12) with openings. The system (10) enables control of the temperature of the supplied air by varying the flow resistance at an output end of a constant air supply source (27), such as a positive displacement blower. By increasing the flow resistance at the output end of the blower (27), with a variably controllable valve (29), the operating temperature of the blower (27) increases and thereby causes a corresponding increase in the temperature of the air supplied therefrom. By varying the flow resistance a user can vary the temperature of the air supplied to the piping network (12) and to the root zone, thereby to control the amount of warming of the root zone so as to reduce the onset, degree, or duration of turf dormancy during the winter season.

Abstract: A device for subsurface irrigation of plants that can be adjusted, assembled, and installed in the ground during the user's desired length at the time of execution and bring the water to the appropriate depth. The device consists of smaller parts, including the leading part, the middle parts, and the end parts, which are connected and make the desired length. Also in this design, it is possible to add magnets to magnetize water as an option for There is also a consumer as well as a sponge brokerage in the vertical channel of the part for further purification and sedimentation. In this device, the middle parts form the main part and by increasing or decreasing them, the final length of the device is determined and they have holes for irrigation in their body.

Abstract: A gravity irrigation system includes a distribution piping having apertures to distribute water to a field, and a valve located upstream of the distribution piping. The valve is configured to limit a pressure of the water being delivered to the distribution piping. The system also includes a sump configured to receive the water at a lowest elevation of the field, a depth sensor disposed within the sump, and a return pump disposed at least partially within the sump and configured to move the water to an elevated portion of the field. The system also includes a motor configured to drive the return pump, and a power source coupled to a variable frequency drive. The variable frequency drive is configured to power the motor and control a motor speed proportionately to an indication of the depth sensor. The system also includes a transfer piping coupled to an outlet of the return pump to bring the water from the return pump to a check valve and from there to the distribution piping at a low pressure side of the valve.
