Poly Pipe Trailer for ATV Deployment of Multiple Inlet Irrigation of Rice Irrigation


Multiple inlet rice irrigation (MIRI) is the use of lay-flat poly pipe to distribute irrigation water across levees in contour and precision graded rice fields.  MIRI can reduce water use by 25% in some studies and has increased yields in others.  Producers wishing to implement alternate wetting and drying (AWD) aka intermittent flooding must use MIRI as part of this new water savings practice. Currently AWD is not implemented in Arkansas and MIRI is only used on about 25% of acres in Arkansas.  One disadvantage of MIRI is damage to levees while deploying the pipe. Additionally farmers either roll the pipe out using tractor-mounted equipment or roll the pipe on the ground, which can damage the pipe. Furthermore it takes more time to move from site to site with a tractor to deploy pipe in fields, at a time when the labor demand to flood up rice fields is high for rice farmers.


These devices allow pipe to be deployed by an ATV or ATU or other small low ground pressure vehicle.  They are designed to traverse levees and fields minimizing damage to the levees while carrying these heavy rolls of pipe.  One of the designs includes an apparatus to install a small furrow to keep the pipe in place.  Currently farmers make a prior trip to install this furrow, so this can reduce labor for the owner.  The device is lightweight and much smaller than a tractor mounted device and can be transported in the bed of a pickup or trailer when the ATV and pipe rolls are also moved between fields.
