The assessment of the irrigation potential, based on soil and water resources, can only be done by simultaneously assessing the irrigation water requirements (IWR). Net irrigation water requirement (NIWR) is the quantity of water necessary for crop growth. It is expressed in millimeters per year or in m3/ha per year (1 mm = 10 m3/ha). It depends on the cropping pattern and the climate. Information on irrigation efficiency is necessary to be able to transform NIWR into gross irrigation water requirement (GIWR), which is the quantity of water to be applied in reality, taking into account water losses. Multiplying GIWR by the area that is suitable for irrigation gives the total water requirement for that area. In this study water requirements are expressed in km3/year. IWR – Irrigation Water Requirement MWR – Net Irrigation Requirement GWR – Gross Irrigation Water Requirement What’s In Directions: Answer the following guide questions in your notebook. 1. What is irrigation to you? 2. How does irrigation help in your daily lives? 2 NegOr_Q3_Agri-CropProd10_Module5_v2 Downloaded by CHER ICHAD ([email protected])  lOMoARcPSD|31411564 What’s New Direction: Write TRUE if the statement is correct, otherwise write FALSE if it is wrong. Write your answers in your notebook. _________1. To irrigate is to water crops by bringing in water from pipes, canals, sprinklers, or other man-made means, rather than relying on rainfall alone. _________2.

What is It Courtesy of canva.com A growing population and rising incomes have challenged agricultural supply and led to drastic increases in irrigated agriculture. Globally, irrigated acreage increased by 76% between 1970 and 2012. Irrigated 3 NegOr_Q3_Agri-CropProd10_Module5_v2 Downloaded by CHER ICHAD ([email protected])  lOMoARcPSD|31411564 agriculture can produce crop yields two to four times greater than rain-fed agriculture. Importance and Benefits of Irrigation System In our Life To irrigate is to water crops by bringing in water from pipes, canals, sprinklers, or other man-made means, rather than relying on rainfall alone. Places that have sparse or seasonal rainfall could not sustain agriculture without irrigation. In areas that have irregular precipitation, irrigation improves crop growth and quality. By allowing farmers to grow crops on a consistent schedule, irrigation also creates more reliable food supplies. Ancient civilizations in many parts of the world practiced irrigation. In fact, civilization would probably not be possible without some form of irrigation. The earliest form of irrigation probably involved people carrying buckets of water from wells or rivers to pour on their crops. As better techniques developed, societies in Egypt and China built irrigation canals, dams, dikes, and water storage facilities. Ancient Rome built structures called aqueducts to carry water from snowmelt in the Alps to cities and towns in the valleys below. This water was used for drinking, washing, and irrigation. Modern irrigation systems use reservoirs, tanks, and wells to supply water for crops. Reservoirs include aquifers, basins that collect snowmelt, lakes, and basins created by dams. Canals or pipelines carry the water from reservoirs to fields. Canals and pipelines, just like the ancient Roman aqueducts, often rely on the force of gravity. Pumps may also move water from reservoirs to fields. Crops are irrigated by several methods: flooding an entire field, channeling water between rows of plants, spraying water through large sprinklers, or letting water drop onto plants through holes in pipes. Letting water drop onto plants through holes in pipes, known as drip irrigation, is considered one of the most efficient methods of irrigation. Drip irrigation focuses the water onto the plant itself. Other methods can waste water by letting it absorb into the ground where there are no plants. Water can also evaporate into the air when sprayed through sprinklers. To irrigate is to water crops by bringing in water from pipes, canal, sprinklers, or other man-0made means, rather than relying on rainfall alone. Places that have sparse or seasonal rainfall could not sustain agriculture without irrigation. In areas that have irregular precipitation, irrigation improves crop growth and quality. By allowing farmers to grow crops on a consistent schedule, irrigation also creates more reliable food supplies. 4 NegOr_Q3_Agri-CropProd10_Module5_v2 Downloaded by CHER ICHAD ([email protected])  lOMoARcPSD|31411564 Safety Around Irrigation Systems Irrigation Safety Just because an irrigation system and related equipment works doesn’t necessarily mean it is safe or will fail in a safe manner. To ensure safety during operation, maintenance, inspection and testing of systems, employees must be aware of the potential hazards they might be exposed to and understand safe work practices necessary around these systems. General Safety Training General safety training for any type of system involves the following areas:  Understanding Equipment and Installation Requirements (What systems look like).  Identifying Common Hazards.  Understanding Safe and Unsafe Work Practices.  Communicating Unsafe Equipment and Installations to Appropriate Entities. Irrigation System Accidents There are different types of potential accidents that can cause injury or death when working on or around irrigation systems including:  Electrical Contacts/Accidents  Contacts/Entanglements with Moving Parts  Chemical Exposures/Poisonings  Falls from the System  Drowning  Physical (Head, Eye, Ear, Hand & Foot) Accidents Irrigation Problem Areas Typical irrigation accidents fall into the following three categories or combinations including:  Faulty Equipment and/or Installation by manufacturer, dealer or installer.  Equipment/Installation correct but modified or poorly maintained by owner (state of disrepair).  Unsafe work practices by individuals during maintenance, repair and testing. Equipment Design/Installation The first link in the chain of irrigation safety is proper equipment design, selection, and installation by manufacturers, equipment dealers, and installers. Irrigation System Maintenance 5 NegOr_Q3_Agri-CropProd10_Module5_v2 Downloaded by CHER ICHAD ([email protected])  lOMoARcPSD|31411564 The second link the irrigation safety chain involves maintaining properly installed systems in good shape.  Many irrigation systems are poorly maintained and fall into states of disrepair.  Many systems have been modified or repaired using substandard equipment. Safe Work Practices Even if the equipment and installation is correct and the system has been well maintained, people still need to use safe work practices to avoid the normal hazards associated with operation of the equipment. Irrigation Safety Requirements  Manufacturers must design equipment to safety standards.  Dealers must install equipment correctly.  Owners, Irrigators and Service people must maintain equipment correctly.  Owners, Irrigators and Technicians must use Safe Work Practices. Irrigation System Hazards Include:  Electrical Contacts – overhead power line contacts, short circuits, working on energized equipment, lightning strikes.  Contact/Entanglement with Moving Parts – working on energized equipment including PTO's, drivelines, gearboxes, tires, etc.  Chemical Exposures/Poisonings – exposure vs ingestion  Falls from the System  Drowning - rivers, lakes, canals, ponds, pits, etc.  Physical Damage (Head, Eye, Ear, Hand & Foot) Irrigation Hazard – Drownings  Drowning is not a common source of irrigation accidents.  Accidents do occur and the potential for hazard is always there due to the amount of water present with systems pumping from lakes, rivers, streams, ponds, or pits.  Most accidents involve falls and slips or recreational activities in water bodies such as rivers, lakes, ponds, or pits used for irrigation.  Be aware of possible fall and slip hazards when working in the vicinity of bodies of water such as rivers, lakes, ponds, and pits used for irrigation.  Irrigation Hazard - Structural Integrity Visually inspect for any signs of loose or missing bolts or visual indications that an irrigation machine is close to a structural collapse before moving the machine or climbing onto the machine. Irrigation Hazard – Falls 6 NegOr_Q3_Agri-CropProd10_Module5_v2 Downloaded by CHER ICHAD ([email protected])  lOMoARcPSD|31411564  Many irrigation systems are tall enough that falls from their structure can cause serious injury or death.  Depending on where a person falls from the system, they may make contact with structural members and other sharp objects during the fall.  There may be enough hand/footholds for a person to scale/climb up onto the machine but it should not take the place of a ladder or other lift device.  The metal structure of most self-propelled irrigation machines does not meet the requirements of a safe ladder.  Use a good ladder or stable lift device to perform overhead repair and maintenance on an irrigation machine.  Ladders can also be dangerous when used in unleveled, tilled, muddy fields when not anchored properly. Irrigation Hazard Chemical Exposure/Poisoning  Increased use of chemigation/fertigation through irrigation systems has resulted in increased numbers of chemical exposures & poisonings.  Chemical exposures can be through exposure to system water, standing water, or crops or drinking water from systems used for this purpose. Irrigation Hazard Chemical Exposure/Poisoning  Be careful of exposure to spray systems or crops under them when chemicals or fertilizers have been injected into the water.  Don’t drink from any system used to apply chemicals.  Avoid areas of obvious chemical spills. Irrigation Hazard - Water Jet  Avoid getting your body in contact with high pressure water streams of any type, especially end guns on self-propelled machines.  High pressure water jets can cause physical harm, especially to eyes, and can also cause falls from irrigation systems. Irrigation Hazard – Entanglements  Do not approach or work around unguarded power takeoff shafts, belts and other and other power transmitting devices.  Alert others in the vicinity and the owners or operators to the hazard.  Avoid wearing loose clothing or long hair in the vicinity of rotating equipment.  Be alert to unguarded power take-off shafts, belts, and other power transmitting devices.  Replacements and retro-fit guards are available from dealers for older machines. 7 NegOr_Q3_Agri-CropProd10_Module5_v2 Downloaded by CHER ICHAD ([email protected])  lOMoARcPSD|31411564  OSHA does not require driveshaft covers on center pivot irrigation machines. o Slow rotation speed. o Operator is supposed to disconnect the power prior to any maintenance or repair work. o Most manufacturer’s install them to prevent crop wrappage.  Industry standards require manufacturers to provide safety signs on motors/equipment that could start automatically to alert personnel performing repair & maintenance to the potential hazard and to shut off power before working on the system.  Never attempt to remove vegetation or other foreign materials from rotating equipment while it is moving or the equipment is energized.  ALWAYS shut down the machine for repair or maintenance. Irrigation Hazard - Run Overs  Keep vehicles and other equipment out of the paths of self-propelled irrigation machines.  Many of these machines have excellent traction and can “climb” over and crush fairly large objects like cars, pick-ups, and even small buildings due to their weight. Irrigation Hazard - Squeeze Points Keep in mind that even if equipment is not run over, you could get squeezed between the system and a fixed piece of equipment it barely misses. Irrigation Hazard - Fuel Leaks  Be alert to fuel leaks from storage tanks and fuel lines.  Sparks from electrical shorts can ignite these fuels or any gas and oil accumulations from leaking storage systems, fuel lines or improper storage containers. Irrigation Hazard - Fuel Ignition  Gasoline, natural gas and propane all ignite from 2 to 15 percent vapor concentration.  Be careful around unmarked storage containers because there is a high probability, they do not contain what their label indicates. Irrigation Hazard Electrical Contacts Electrical safety concerns related to irrigation systems are important because:  Pumps and other equipment operate in a wet or damp environment increasing the chance of equipment failure if parts become wet.  Personnel working around this equipment are often wet or damp so their susceptibility to electric shock is greater.  Many of these systems may not have had proper maintenance performed on them over the years.  8 NegOr_Q3_Agri-CropProd10_Module5_v2 Downloaded by CHER ICHAD ([email protected])  lOMoARcPSD|31411564 Irrigation Hazard Electrical Contact Accidents  Faulty Equipment & Wiring Installations & Maintenance.  Unsafe Work Practices o Failure to turn off power before working on system.  Lightning  Overhead Power Lines o Irrigation Pipe, Standing on Systems, Spraying Water on Overhead Lines. Do Water & Electricity Mix?  They can……if proper safety precautions are followed. o Proper Equipment Selection o Proper Installation Methods o Proper Maintenance Practices o Use of Safe Work Practices Electrical Safety Goal Don’t let any part of your body be a path for electricity to flow through you. Electrical Wiring Standards  Many pumping systems and water distribution systems are electrically powered and many irrigation accidents are the result of electrical contacts or not turning off the power.  Irrigation Systems should be wired to at least the requirements of the National Electrical Code (NEC). National Electrical Code (NEC)  The consensus safety standard of the electrical industry: o How to install a safe electrical system to electrical utilization equipment of most any kind. o A minimum standard... dictates wiring & equipment necessary to be safe, not to work well. NEC Electrical Requirements Article 675 - Irrigation Machines Pumps & Irrigation Machines  Must have disconnect switches  Must use equipment & enclosures suitable for the conditions (wet, dirty, corrosive, etc.)  Must protect wires from physical damage or use “jacketed” irrigation cable  Must have circuit and equipment grounding. Equipment & Installation Problems 9 NegOr_Q3_Agri-CropProd10_Module5_v2 Downloaded by CHER ICHAD ([email protected])  lOMoARcPSD|31411564 Common unsafe equipment selection, installation & maintenance problems include:  No Electrical Disconnect(s) to Turn Off Power  Improper Equipment or Installation  Improper Electrical Grounding  Faulty insulation on wires and power cords Pumping System Disconnect  The disconnect switch for the pump should only control the pump motor.  Equipment such as irrigation machines or fertilizer or chemical injectors should not be supplied from the load side of the pump disconnect through the pump disconnect switch. Irrigation Machine Disconnect Irrigation machines require a disconnect switch with overcurrent protection (fuses) capable of being locked in the open position at the point of connection of electric power to the machine. Machine Disconnect Switch  Most Manufacturers provide this as part of the control panel on the irrigation machine.  Allows power to be turned off to the entire machine from one location.  Allows the power to be “locked” off for maintenance & repair. Switches/Controls  Should be mounted at a height to prevent the need for kneeling or climbing.  Handles for disconnects must not be higher than 6.5 feet or lower than 3 feet.  All switches must be permanently labeled for their function and use. Examples are the following: o Pivot o Water Pump o Injection Pump Electrical Enclosures/Boxes Electrical enclosures and boxes are used to guard operators from live electrical parts (electrical connections, switching mechanisms, etc) in the pump control panel, irrigation machine control panel, and other related electrical devices.  Weatherproof or watertight equipment enclosures and boxes for all irrigation systems.  Look for holes and openings that allow rodents and/or water and other foreign materials to enter and accumulate in panels and other enclosures. 10 NegOr_Q3_Agri-CropProd10_Module5_v2 Downloaded by CHER ICHAD ([email protected])  lOMoARcPSD|31411564 Electrical Enclosures  All electrical enclosures should be suitable for the environmental conditions they are exposed.  Generally requires “weather-proof” or “water-proof” enclosures.  Should not have openings that allow water, dirt or rodents. Inadequate Working Space Around Equipment All electrical equipment is required to have specific clear “working space” around it depending on location and voltage. Inadequate Working Space The NEC requires equipment have adequate working space for people to work on it.  Mounting height is important.  You should never have to bend over, kneel or lay on your back, side or stomach to operate a switch, or other control device. Irrigation Machines Conductors o All electrical conductors SHALL be within an enclosure, a raceway (conduit), or a jacketed cable. o Most systems use a heavy duty jacketed “irrigation cable” which has more protection than an “extension cord” Improper Maintenance of Systems Common problems related to improper or poor maintenance of systems include: o Open Electrical Enclosures (boxes) o Broken or Damaged Electrical Conduit o Use of Damaged Electrical Power Cords o Improper Fuse Replacement Unsafe Work Practices Installation of the safest and best maintained electrical system can still result in electrical accidents if unsafe work practices are used by personnel performing repair, maintenance or testing of the system. Irrigation System Safe Work Practices  Wear appropriate clothing and use any necessary personal protective equipment.  Visually inspecting the equipment prior to touching. 11 NegOr_Q3_Agri-CropProd10_Module5_v2 Downloaded by CHER ICHAD ([email protected])  lOMoARcPSD|31411564 o Look for unguarded drive-lines and other mechanical hazards. o Locate the equipment disconnect switches/devices. – Look for broken or damaged equipment and electrical insulation on cords and open or damaged electrical enclosures.  Test the equipment (voltmeter and/or backhand)  Disconnect energy sources prior to repair, maintenance and testing.  Practice Lockout/Tagout Personal Protective Equipment (PPE)  Personal Protective Equipment (PPE) provides people protection from various hazards likely to arise in the workplace.  The most common types of PPE include head, ear, eye, hand, and foot protection. Heat Stress  Individuals performing maintenance or testing of irrigation systems can be exposed to very high temperatures and possible heat stress.  Heat stress can cause various bodily distress including dizziness, elevated body temperature, nausea, and in severe cases can result in death.  Dress appropriately for the field and conditions.  Ensure adequate drinking water or fluids are available (don’t rely on drinking from the irrigation system). Eliminate Problem Clothing & Jewelry/Accessories  Secure Long Hair & Eliminate: o Jewelry (rings, watches, chains, large belt buckles etc.) o Loose clothing (ties, scarves, etc.)  Metal jewelry is electrically conductive and long hair & loose clothing can easily become caught in rotating parts. Foot Protection  Typical foot hazards encountered when working around irrigation systems include rough, un-even ground and frequent muddy conditions.  Comfortable foot wear appropriate for wet, muddy conditions and un- even terrain is required. Hand Protection  Irrigation systems generally consist of significant quantities of machined metal with sharp edges and lots of protruding bolts and other connectors. 12 NegOr_Q3_Agri-CropProd10_Module5_v2 Downloaded by CHER ICHAD ([email protected])  lOMoARcPSD|31411564  Appropriate hand protection in the form of gloves is generally warranted for technicians performing maintenance and testing on irrigation systems. Head Protection  Most owners and operators typically do not wear head protection when working on/around irrigation systems.  Falling objects are rarely ever encountered however, bumping your head on the structure can be painful.  A Class 1 head protective device (hard hat) is adequate for working around irrigation systems. Noise - Hearing Damage  Many fossil fuel power units will produce significant amounts of noise that will damage hearing slightly if exposure is sufficient.  Wear appropriate hearing protection when working around this type of equipment. Noise - Hearing Protection  Irrigation pumps powered by fossil fuel engines are extremely loud.  Hearing Protection can be provided through PPE by wearing either approved earplugs or earmuffs.  Cotton balls stuffed in your ears will not provide hearing protection. Eye Protection  Most owners and operators typically do not wear eye protection when working on/around irrigation systems.  Technicians performing maintenance or testing of most any type should have and use appropriate eye protection when working on irrigation systems even if owners and operators do not. Visually Inspect the System/Area  Locate the disconnect switches for the irrigation equipment o pump(s), irrigation machine(s), other equipment  Look for missing lids & enclosure covers exposing live electrical parts.  Look for damage from equipment or livestock on exposed electrical panels and cords.  Look for missing guards on moving and rotating equipment. Good Judgment Perhaps the single most successful defense against irrigation accidents is an understanding of the potential hazards, following safe work practices, and continuous use of good judgement. 13 NegOr_Q3_Agri-CropProd10_Module5_v2 Downloaded by CHER ICHAD ([email protected])  lOMoARcPSD|31411564 What’s More Direction: True or False.
