5 Factors to contemplate when choosing irrigation pump

rrigation pumps are often used to pump water from a lower to a higher stage from which the water then flows through channels to the fields requiring irrigation or to lift it to the required pressure head so as to spray the fields by way of piping systems (sprinkling). The heads concerned vary from approx. 1 m for regular carry operation to forty m for sprinkling. Ocassionally, heads more than 100 m could additionally be required.
At instances, irrigation pumps are often not geared up with variable velocity drives. The circulate fee can therefore be managed by either switching the pumps on and off, or by using a throttling valve within the discharge pipe, pre-swirl control (e. g. cooling water pumps), rotational speed or impeller blade pitch adjustment. Both horizontal and vertical pumps (e. g. tubular casing pump) are used as irrigation pumps.
For greater than 2,000 years farmers have used irrigation to grow food for the world. However, this doesn’t mean that all irrigation methods are equally useful. Knowing what will work best in your situation requires information about the choices obtainable, including the advantages and drawbacks of every. With that in mind, here’s a look at five things to contemplate in getting water to your crops:
1. Soil sort. The kind of soil in an space can have an result on not only the type of irrigation method used but also the irrigation run times. Sandy soils sometimes require frequent functions of water at a high fee to maintain moisture in the root zone. Clay soils has a characteristic of holding moisture longer that sandy soils, even so, this may require frequent functions at a decrease fee to forestall runoff.
2. Land topography. When it comes to land considerations, hilly or sloping land could be a challenge. Drip irrigation works nicely if the laterals can be run alongside topographic traces. Often system run times could need to be adjusted to prevent runoff. Travelers and heart pivot systems are usually out of the query on hilly and severely sloping land.
three. Don’t miss out . In this case, sprinklers are less desirable in areas where high winds are widespread and in arid areas with a low humidity since water losses as a outcome of evaporation could be extraordinarily excessive. Drip irrigation works well for both of the above mentioned conditions.
4. Type of crops grown. Sprinkler and drip methods can require high ranges of funding. Therefore, it’s higher to order their use for high-value crops like greens, small fruits and orchard crops quite than applying them to commodity crops like wheat and soybeans.
5. Water quality. All drip irrigation techniques require some kind of filtration. Overhead systems similar to sprinklers seldom require filtration. Irrigation water must be tested for water borne pathogens. Depending on the crop grown and irrigation methodology used chlorine injection may be required. Safety that could presumably be of concern embrace ranges of soluble iron and other dissolved minerals.
