With the onset of summer, everyone is busy with irrigation. Since the canals are not opened and the water in the streams has reduced, many people are now depending on micro-irrigation methods. As the intense heat increased with the approaching monsoon, crops in the farmlands had to be irrigated continuously.

The difficulties caused when these methods, which help in using the available water efficiently, are obstructed are not small.


🚰 Why Micro-Irrigation Systems Stop Working

Micro-irrigation systems like drip irrigation, sprinkler irrigation, and mist irrigation have been in all farmlands for a long time. Automatic systems have even started to water the beloved greenery in apartments, which are a part of the cosmopolitan lifestyle.

Often, many installed systems may become dysfunctional, leading to withering, unhealthiness, and difficulty in timely repairs, making them useless.


🧰 Filter Clogging Is The Main Problem

The clogging of filters and the accumulation of dirt is a major reason for blockages. Also, mud, mold, and moss. If these are avoided, the problem can be reduced to a great extent.

🌿

Also, mud, mold, and moss can obstruct the proper functioning of the system.

🔎

Install sand filters, disc filters, and screen filters.

🗓️

The disc and screen filters should be cleaned at least once a week.

🧪 Cleaning methods mentioned: Popular methods use lemon, baking soda, hex, and bitter gourd.

Clean by passing a 20 ppm bleaching powder solution through the pipes. They can also be cleaned using acid solutions.

Any one of hydrochloric acid, sulfuric acid, nitric acid, or phosphoric acid can be used. The acid solution needs a concentration that brings the pH of the water to 2-3.


💧 Enough Water For Each Crop

Drippers should be arranged in a way that ensures each crop gets the required amount of water. The table shows the amount of water required for different crops and the number of drippers needed to provide it.

Crop Required water (liters) Number of drippers and operating time
Vegetable 2-4 1 (2 liters per hour)
Banana 16-25 2 (8 liters per hour)
Coconut 70 4 (14 liters per hour)
Areca nut 16 2 (8 liters per hour)
Nutmeg/Vanilla 24 3 (8 liters per hour)

🔬 Drip Clean Device For Maintenance

A simple device developed at the Thiruvananthapuram Tuber Crops Research Centre for the maintenance of micro-irrigation systems is now available among farmers.

This method of passing an acid solution through the existing drip system is named Drip Clean. A startup venture named Farmplast has developed this. For more information, contact this number.

FAQ

Why does drip irrigation get blocked in summer?

Drip irrigation often gets blocked because filters clog and dirt accumulates inside the system. Mud, mold, and moss can also obstruct the flow. During summer, farmers irrigate continuously, so even a small blockage can quickly affect water delivery and lead to crop withering or unhealthy growth.

How often should disc filters and screen filters be cleaned?

The disc and screen filters should be cleaned at least once a week. Weekly cleaning helps prevent accumulated dirt, mud, mold, and moss from entering the pipes and drippers. This simple maintenance step can reduce blockages to a great extent in micro-irrigation systems.

Which filters are useful for preventing drip irrigation blockages?

The article recommends installing sand filters, disc filters, and screen filters. These filters help remove different types of particles before water enters the drip lines. When they are cleaned regularly, they protect drippers from clogging and help the system deliver water more uniformly.

Can bleaching powder solution be used to clean drip pipes?

Yes. The article mentions cleaning by passing a 20 ppm bleaching powder solution through the pipes. It also notes that acid solutions can be used. These methods are intended to clear blockages and deposits inside the existing drip system when filters and pipes become obstructed.

What acid concentration is needed for drip system cleaning?

For acid cleaning, the solution needs a concentration that brings the pH of the water to 2-3. Hydrochloric acid, sulfuric acid, nitric acid, or phosphoric acid can be used. Farmers should handle acid solutions carefully and use the method only as suitable for the installed system.

How many drippers are needed for banana and coconut?

For banana, the table lists 16-25 liters of required water with 2 drippers operating at 8 liters per hour. For coconut, it lists 70 liters of required water with 4 drippers operating at 14 liters per hour. Dripper placement should ensure each crop receives the needed amount of water.

What is Drip Clean in micro-irrigation maintenance?

Drip Clean is a method of passing an acid solution through the existing drip system. It is based on a simple device developed at the Thiruvananthapuram Tuber Crops Research Centre for micro-irrigation maintenance. A startup venture named Farmplast has developed it for farmers.
