VRI — Vari­able Rate Irrigation

Water is a pre­cious resource, which needs to be con­served. With reg­u­la­tors apply­ing pres­sure on an array of ever stricter reg­u­la­tions regard­ing water usage, and envi­ron­men­tal pro­tec­tion increas­ing world­wide, Bauer saw a need to develop prod­ucts to meet these requirements.

With the BAUER VRI solu­tion, water is applied in the most eco­nom­i­cal way pos­si­ble: pre­cip­i­ta­tion is pro­grammed to auto­mat­i­cal­ly and pre­cise­ly adjust to dif­fer­ent crops and soil types, unnec­es­sary areas can be left out, also pre­vent­ing over or under appli­ca­tion. Efflu­ent can also be applied without issue. It is impor­tant to max­imise the use of waste water, pro­vid­ing the plant with suf­fi­cient water and nutri­ents, while meeting all offi­cial reg­u­la­tions. BAUER VRI makes this simple!

TOP ben­e­fits from BAUER VRI:

  • Water appli­ca­tion is set for the correct amount of water exactly in each sector of the field, reduc­ing overall water usage, in some cases, significantly.
  • Water appli­ca­tion can be varied to soil type: Sat­u­rat­ed areas need less irri­ga­tion, while drier areas will need more water.
  • Sep­a­rat­ed efflu­ent or liquid manure can be irri­gat­ed in the most uniform appli­ca­tion pos­si­ble without issue: due to special VRI valves, block­ages and cor­ro­sion are minimised.
  • Irri­ga­tion of spe­cif­ic areas, such as build­ings, ditches, wet areas, water troughs, laneways, or other non-irri­ga­ble areas in the field can be switched to zero irrigation.
  • Runoff is sig­nif­i­cant­ly reduced, added fer­til­iz­er nutri­ents are retained uni­form­ly and are readily avail­able for plant uptake.
  • Offi­cial irri­ga­tion & waste­water reg­u­la­tions can easily be met (e.g. pro­tect­ing water­ways & cattle water with appro­pri­ate setback dis­tances to avoid contamination).
  • Oper­a­tions are in real time, GPS loca­tion is updated every 30sec – 3 minutes. This is nec­es­sary for VRI wot work cor­rect­ly. No cal­cu­lat­ed posi­tion is used.

The VRI principle

VRI (Vari­able Rate Irri­ga­tion) means that water appli­ca­tion rates within select­ed areas of one field, can be adjust­ed to the exact pre­cip­i­ta­tion rate to crop require­ment and soil mois­ture holding capac­i­ty. In addi­tion, select­ed areas can be exclud­ed from the irri­gat­ed zone, such as troughs, water­ways, build­ings and laneways. This ensures that no water is wasted.

The VRI prin­ci­ple is based on acti­va­tion and deac­ti­va­tion of indi­vid­ual nozzles, which are con­trolled by Bauer’s unique VRI boxes via a BUS system. Depend­ing on plant require­ments, areas within the field are pro­grammed for dif­fer­ent appli­ca­tion rates. The Bauer system is remote mon­i­tored and con­trolled, via Bauer’s Smar­tRain server. With this system in place, less time is required in the field. Smar­tRain allows the user to see every machine func­tion, and adjust the func­tions remotely.

Hard­ware and Software

BAUER VRI is avail­able for BAUER Pivots, Linear and Cen­ter­lin­er systems. A Retro-fit kit for exist­ing systems is also available.

The main com­po­nents of the BAUER VRI solu­tion are:

  • Electro-hydraulic valves with cus­tomised filter specif­i­cal­ly designed for opti­mized water appli­ca­tion in dif­fer­ent sectors. The valves are also suit­able for the irri­ga­tion with screened indus­try waste­water or sep­a­rat­ed liquid manure.
  • Special Bauer VRI control boxes control the valves via a BUS system, using opening and closing impuls­es, which are fully adjustable.
  • For installing VRI, Pivots, Linears, or Cen­ter­lin­er systems need to be equipped with a Smart­Touch or Uni­ver­salTouch control panel and be con­nect­ed to Smar­tRain remote management.
  • The Smar­tRain app is required for remote control and mon­i­tor­ing of the irri­ga­tion systems via PC, smart­phone or tablet.

VRI Pre­scrip­tion Features

With VRI it is certain that no water is wasted. The BAUER VRI solu­tion guar­an­tees effi­cient use of the avail­able water resources, while deliv­ery max­imis­es crop yields: you’ll get more out of every hectare. To fully benefit from VRI, a pre­scrip­tion program is set up with Smar­tRain, where field data, soil types, and holding capac­i­ty can all be fac­tored in to  create an irri­ga­tion plan tai­lored to the field and crop requirements.

How you cus­tomize and opti­mize your irri­ga­tion management:

  • The dif­fer­ent irri­ga­tion sectors (poly­gons) are drawn on a map via the Smar­tRain portal or import­ed via Shape, KML or KMZ files.
  • Based on your irri­ga­tion plan, the required appli­ca­tion depth (as a per­cent­age of the maximum appli­ca­tion) is pro­grammed for each indi­vid­ual sector.
  • No irri­ga­tion zones, can easily be edited out of the irri­ga­tion plan. This ensures water is not wasted in areas where it is not required (e.g. on laneways, or waterways).
  • The result: Your VRI system will auto­mat­i­cal­ly and pre­cise­ly adjust the pre­cip­i­ta­tion amounts to the set indi­vid­ual zones. Switch­ing from one zone to the next is fully auto­mat­ic. Change of pre­scrip­tion can also be carried out remotely.

Remote control and monitoring

With Smar­tRain and VRI, your irri­ga­tion machine can easily be con­trolled from any PC, smart­phone or tablet:

  • You can monitor your irri­ga­tion machine at all times, and see the real time pivot loca­tion at any given time.
  • You can check data such as current speed, pre­cip­i­ta­tion depth, or con­nec­tion pres­sure at any time.
  • You can control the system remote­ly, and for example, change pre­cip­i­ta­tion rate, appli­ca­tion depth, end gun seg­ments and direc­tion if necessary.
  • In the event of unfore­seen inter­rup­tions, you will be alerted imme­di­ate­ly by txt or email, or both.
  • Reports on water con­sump­tion, pre­cip­i­ta­tion rates, or other data, can be created at any time.
