Why Use Irrigation Control?

Irrigation control is a technique used to manage an irrigation system. Irrigation control systems manage electric valves that regulate the flow of water through piping systems. Automatic irrigation controllers allow water to flow to specific crops, or zones, based on a triggers such as time, soil conditions, solar radiation accumulation, environmental controls, and other algorithms. This type of automation can be complex, since water must be applied to plants in specific volumes over varying amounts of time

Advantages of Installing an irrigation system

01.

Agriculture is often greatly hampered due to irregular, insufficient or uncertain rain. Proper irrigation systems can secure uninterrupted agriculture.

02.

The productivity of irrigated land is more than the un-irrigated land. Crop yields everywhere in the developing world are consistently higher in irrigated areas than in rainfed areas

03.

Seeds cannot grow in dry soil as moisture is necessary for the germination of seeds. With the help of irrigation supply, the required moisture content of soil for the growth of seed can be ensured

04.

Irrigation contributes to the economic growth and poverty reduction2. As income and employment are closely related to output and irrigation increases production, substantial increase in income is achieved in the countryside

05.

Through the irrigation, it is possible to supply the required amount of hydrogen & oxygen, which is important for the proper development of plant root

06.

Multiple cropping in a year is possible through irrigation. This will enhance production & productivity

07.

A plant can absorb mineral nutrients from the irrigated soil. Thus irrigation is essential for the general growth of the plant

08.

Insufficient rain may also cause drought & famines. Irrigation can play a protective role during the period of drought & famines

09.

Bringing more land under cultivation is possible through irrigation

Why Have Fertigation Control?

Fertigation is the process of running fertilizer through irrigation water. The practice of running plant nutrients through irrigation systems has increased dramatically over the last 20 years. As careful water management and sustainability become more common issues, the need for high yields of superior-quality crops has increased. Because of this, more growers are exploring the advantages of combining their water and fertilizer applications.

Using a Fertigation System

With the introduction of better technology, applying pesticides has become more wide spread as a necessary compliment to fertilizer injection.

Drip and micro-irrigation, prevalent in greenhouses and hydroponic environments, have a characteristic not shared by other irrigation methods; fertigation is not an option but is actually necessary. Fertigation provides the only truly efficient way to apply fertilizers physically to the crop root zone. On high value crops, such as lettuce, tomatoes, and commercially produced potted plants, the level of fertigation management for achieving high yields and qualities exceed what is found with other irrigation methods.

The Benefits of a Fertigation System

Fertigation increases efficiency by delivering water and nutrients directly into the root zone, where they’re most needed. This results in the need for less fertilizer and water. Other potential advantages of fertigation include flexibility, saving on labor and energy costs, and the ability to add nutrients that may be otherwise difficult to apply.

Properly automated commercial greenhouses, hydroponics operations, and agricultural fields will reduce their costs for chemicals and labor while increasing crop yields and health. Hanna has three customizable options to fit any size facility.

This level of flexibility coupled with remote access allows the entire fertigation process to be monitored and controlled from anywhere in the world, saving you time and giving you more freedom.
