Irrigation systems agriculture

Types of irrigation systems for agriculture

An irrigation system for agriculture is a method used by farmers to supply water to crops on a farm. Different kinds exist depending on how water is delivered to the crops. Here are some common types of irrigation systems for agriculture:

• Drip irrigation: A drip irrigation system for agriculture is designed to slowly and steadily supply water directly to the roots of plants. A net-like tubing system is mounted above or below the crop canopy at the plants' base. It is a functional and efficient method of irrigating plants, lessening weeds, and minimizing water loss through evaporation. It is ideal for high-value fruit and vegetable crops
• Sprinkler irrigation: A sprinkler irrigation system for agriculture sends water upward through pipes and fitted nozzles in a way that mimics rainfall. Water is distributed throughout the farm by rotating heads fixed on vertical risers. It is suitable for row crops, pastures, and solid-set sprinkler systems for high-value fruit crop protected under a shelter can also be used for agricultural sites without adequate rainfall.
• Surface irrigation: Surface irrigation is a method that uses gravity to move water across a farm field. It works best on level and permeable soils and involves flooding the farm either by controlled basin flooding or by farming furrows between fields of crops. Surface irrigation is used in both furrow and flood irrigation. While it is inexpensive to set up, it is not very efficient and can use a lot of water. It works only on certain kinds of soils and slopes.
• Subsurface irrigation: A subsurface irrigation system delivers water to crops below the soil surface, usually provided by a network of perforated pipes or tubes buried within the soil. It is efficient in water use and lessens weed growth and environmental hazards. However, it is costly to install and may require more maintenance than surface irrigation systems.
• Center pivot irrigation: A center pivot irrigation system is a method used on large, circular fields. Water is moved around the central point of a farm by wheeled towers and radial beams that are rotating, and low-pressure sprinklers placed along the beams. This type of automated irrigation is useful where there is enough water to grow crops, but it also works to save water by making it possible to irrigate areas that used to be too dry for farming. The cost of power to irrigate those places can also be low. It is perfect for large-scale farms in flat terrain.

Specification and Maintenance of Irrigation Systems Agriculture

The specifications of irrigation systems vary depending on the type and design. Some of the most common ones are as follows.

• Water Flow Rate

  This is the volume of water that the irrigation system provides to the crops per unit of time. It is usually measured in gallons per minute (GPM) or liters per second (L/s). The amount of water flow depends on some factors like the system type, pump capacity, and pipe diameter.

• Pressure

  Irrigation systems agriculture must work well with the water pressure. The pressure in the system determines the flow rate and distribution of water. It is usually measured in pounds per square inch (PSI) or kilopascals (kPa). Water pressure depends on the elevation of the land, distance from the water source, and pressure from the pump.

• Coverage Area

  An irrigation system can cover a specific area of farmland. It is measured in square feet or hectares. The coverage area depends on the type of system, the number of emission devices, and the spacing between them.

• Energy Consumption

  This is the amount of energy consumed by the irrigation system to pump and distribute water. It is usually measured in kilowatt-hours (kWh). It depends on the system design, pump capacity, operating duration, and efficiency of the system.

For an irrigation system to work for a long time without breaking down, it is essential to maintain it. Here are some of the maintenance practices of the irrigation system that can keep it functional over the years:

• Regular Inspection

  Irrigation systems should be inspected now and then for signs of wear, damage, and leaks. This helps farmers find out any issues quickly and solve them before they become major problems.

• Cleaning

  To prevent clogging and build-up of debris, farmers should regularly clean all components like filters, emitters, and pipes. Keeping the parts of the irrigation system clean helps to maintain proper water flow and quality.

• Adjustment

  The irrigation system should be adjusted from time to time to ensure that water is distributed well. The emission devices should be leveled, spaced appropriately, and their flow rates checked. This will avoid over watering or under watering the crops.

Applications of irrigation systems for agriculture

The main use of irrigation systems for agriculture is to provide consistent water supplies to crops and soil. Numerous industries have benefited from the widespread use of irrigation systems.

• Agriculture: As expected, irrigation system designs are widely used in the farming and agricultural sector. Farmers and agriculturalists install irrigation systems to water crops, plants, and vegetables at a steady pace. This promotes healthy and fast growth, leading to a fruitful harvest. Besides, irrigation systems also help farmers reduce their labor as manual watering is not required. It also helps them expand their farm reach as even far-away fields can be watered with the help of an irrigation system.
• Agriculture-Related Industries: Several industries are related to agriculture but do not directly constitute it. Still, they benefit from irrigation system designs. These include the horticulture industry that deals with floral plantations, the landscaping industry that focuses on public and private outdoor spaces, and the golf course management industry, to name a few. All of the above industries depend heavily on varying irrigation systems to ensure that all gardens, greenhouses, and open fields are well-watered with the least manual labor. Because of this heavy dependence, golf courses, public parks, and landscaping businesses have happily taken to irrigation system designs that are water-efficient and help reduce costs.
• Greenhouses and Nurseries: Greenhouses and nurseries also make full use of irrigation systems for proper and equal watering of all plants and flowers. In fact, these establishments benefit a lot from automated options like drippers and sprinklers that can be programmed according to the plants' watering needs. This also helps greenhouses and nurseries save time.
• Construction Industry: The construction industry needs to ensure adequate soil watering during dry spells when soil stabilization is vital. In such a case, on-site soil stabilization can conveniently be achieved through irrigation system construction using a spray irrigation system.
• Dust Suppression: Dust pollution is a rising environmental hazard that can pose severe health risks to human beings. The highways and dusty unpaved roads often cause enormous amounts of dust to get airborne, which can be harmful. Several road construction companies and local municipalities have relied heavily on irrigation systems for dust suppression. Using these irrigation systems, water is sprayed on the surface to minimize dust pollution.
• Mine Operations: Open-pit mining operations also make use of irrigation systems to suppress dust pollution. Mining activities often create a lot of dust that can pollute the air, but irrigation systems can reduce this effect by wetting the surface. Not only does this provide a more water-efficient option, but it also helps mining companies curb dust pollution and fulfill environmental responsibilities.

How to choose irrigation systems agriculture

A wide range of flexible and cost-effective options are available to business buyers for choosing irrigation systems. The first step for buyers is to conduct a detailed assessment of the land's topography, soil characteristics, climate conditions, and farm layout.

Byers should identify the crops' water requirements, growing stages, and root depths. By considering factors like pressure loss, uniform distribution, and water efficiency, buyers should select the irrigation system suited to their specific fields. Buyers should consider available water sources and quality, such as boreholes, rivers, rainwater, municipal supplies, or deep wells.

The initial setup cost and recurring operating costs are essential, but they should not be the only factors influencing buyers' choices. A well-designed irrigation system can increase productivity and profitability, creating a positive return on investment over time. Buyers should select an irrigation system compatible with specific crops and cultivation practices, such as open fields, greenhouses, orchards, or nurseries.

System efficiency depends on proper pump selection. Buyers should choose a pump with sufficient capacity to maintain the desired flow rates and pressure at optimal energy consumption. The irrigation system components, such as pumps, filters, pipes, valves, emitters, and fencing, should be easy to maintain and replace. Analogously, the chosen irrigation method should suit the farm's energy resources. For example, a solar-powered irrigation system may be economical for remote areas where energy grids cannot reach.

Data-driven automation and smart technology in modern agriculture can improve irrigation systems' precision, efficiency, and convenience. If relevant, buyers should consider selecting an irrigation system with predictive modeling, cloud-based data storage, and remote monitoring. Depending on the area covered, field-mapping tools can be helpful. So, too, can automated conveyance systems, which reduce manual labor and increase system efficiency.
