How To Fertilize Through A Drip Irrigation System - Krostrade

Welcome to the Krostrade Marketplace, please excuse our appearance, we are still under construction.

How To Fertilize Through A Drip Irrigation System

Learning how to fertilize through a drip irrigation system is quite simple, but it involves understanding what fertilizer to use and incorporating it in the injector. This process is also called fertigation and offers many benefits for different production systems. More so, fertilizing itself would be more comfortable through irrigation water, given that you understand how a drip irrigation system works

With proper knowledge in fertigation, you can take advantage of faster water and nutrient uptake. You can also be more efficient in using water and fertilizers. If you’re using a greenhouse instead of an outdoor garden, you may also find fertigation more beneficial for your plant management.

How To Fertilize Through A Drip Irrigation System Correctly


Step #1. Know what fertilizer to use

As one can assume, the proper fertilizer for a drip irrigation system is water-soluble. You will then incorporate a fertilizer injector into the drip irrigation system, which will then disperse the fertilizer for you. This way, you can control both the watering and fertilizing in one system. 


How to avoid clogging

However, do note that you want to avoid clogging the drip emitters with the water-soluble fertilizer. To do this, filter the downstream of the fertilizing unit and use a product that mixes well with water. Remember that a poorly dissolved solution will clog the emitters because the particles will stay in suspension. 

Some other common fertilizer mistakes to avoid are combining chemicals and fertilizers. This can cause residues, which will eventually plug the emitters of the system. You also want to dilute the fertilizer concentration that would suffice one irrigation cycle. 


How to avoid backflow

More so, add something upward to the unit’s stream because a common problem with fertigation is when the fertilizer backflows into the water source. Ensure that you check your device to avoid any issues. Some areas also have laws about the placement of a backflow prevention device.


Step #2. Incorporate fertilizer into the drip irrigation system

The next step is incorporating the fertilizer into the drip irrigation system. You want to check the emitter at a great distance from the pump so that it’s at full pressure. This way, you won’t face problems with the injection from a poorly pressurized drip irrigation system. 


Backflow prevention device and filters

As mentioned earlier, you want to guarantee that no particles will clog the emitters, and you may need to add a backflow prevention device. For the filter itself, consider your injector type and water source to choose the appropriate one and place it between the injector and water source. Another filter is also necessary between the laterals and the injector to keep particles from potentially clogging the emitters. 


How to ensure equal fertilization and prevent clogged drip lines

Once you have all those parts secured, you must allow the system to reach full pressure by injecting the fertilizer. The emphasis is necessary on ensuring that the drip irrigation system is at full pressure because you want each emitter to be in conjunction with each other. This way, you can ensure equal fertilizer distribution throughout the drip irrigation system. 

After the injection, clean the irrigation system thoroughly. Failure to flush the nutrients in the system can clog the drip lines. 


Common Injectors For Fertilizing Through A Drip Irrigation System

In general, fertilizing through a drip irrigation system is as straightforward as adding fertilizer injectors to the drip head assembly. This makes fertigation an excellent option for commercial growers and even those who are growing in the greenhouse. There are two common types of injectors that you can use for a drip irrigation system. 

The first type is an injector that you add to the drip head, which draws the fertilizer for you and injects it into the irrigation system at a concentration. On the other hand, you can also use T and Y filters as injectors and add pellets into them, which will dissolve and enter the system. Both injectors are easy to use as long as you follow the instructions, know your fertilizer, and check their compatibility with your system. 


Other Fertilizing Methods For Drip Systems And What Won’t Work

Some growers do not rely on drip irrigation to fertilize. Instead, they place time-release fertilizer under each emitter or side-dress between the emitter and the plant with a soluble fertilizer. The central concept here is to guarantee that the fertilizer will reach the plant roots and get into the emitters’ wet zone. 

Therefore, you can’t sprinkle dry fertilizer on the soil surface or use a hose to feed with liquid fertilizer. Using manure and other mulch won’t also work because it is underneath it and won’t create a wet zone to bring the nutrients into the soil. 



Fertigation or using a drip irrigation system to fertilize is an excellent way to conserve fertilizer and water and ensure faster uptake of both with your plants. Learning how to fertilize through a drip irrigation system is also something you shouldn’t get intimidated by as long as you understand the two subjects this article has discussed. 

First, understand that a water-soluble fertilizer that readily dissolves in water is crucial to prevent clogging in the system. Second, you want to add filters and a backflow prevention device to anticipate common problems with fertigation such as blocking and backflow of fertilizer. And lastly, you must use the system in full pressure to ensure equal fertilizer distribution.

How to Start an Avocado Farm: 4 Things to Remember

How to Start an Avocado Farm: 4 Things to Remember

Are you interested to learn how to start an avocado farm? Embarking on this journey requires time, effort, and commitment. Plus, you need to consider a number of factors including soil preparation, as well as weather conditions.

You’re probably aware that avocado trees or Persea spp, are originally from Mexico. This explains why one of the famous Mexican cuisines include avocado-based guacamole.

You can choose to grow avocado trees indoors or outdoors. If you plan to grow them in a hobby greenhouse or at home, all you have to do is to sow the seeds in pots. When they’re grown outdoors, avocado trees can grow up to 40 feet. You can al

Moreover, these trees thrive well in regions where the weather is mostly warm and sunny. However, don’t expect them to grow in areas that experience extreme temperatures during the summer and winter.


Avocado: The Superfood

Did you know that the global demand for avocados has been steadily increasing? Aside from the fact that its fruit is known for its full, buttery flavor and rich texture, it’s also packed with loads of essential nutrients that are good for your body.

A single serving of avocado fruit contains vitamin K, vitamin C, folate, potassium, vitamin B1, vitamin B2, vitamin B3, vitamin B5, vitamin B6, vitamin E, manganese, magnesium, iron, copper, zinc, and vitamin A.  It also has protein, fiber, and healthy fats. If you’re on a low-carb plant food diet, you’d want to incorporate avocados into your diet.


What are the Growing Requirements of an Avocado Tree?

Since avocado trees need to be grown in warm semi-humid climates, they only grow in U.S. Department of Agriculture (USDA) plant hardiness zones 8 to 11. However, it’s important to note that while avocado trees may be grown in those zones, they don’t always thrive well in areas that get extremely hot during the summer or frosty, chilly, or snowy in the winter. This implies that the ideal environment for an avocado tree should have moderate temperatures all-year-round.


What are the 3 Primary Groups of Avocado Trees?

If you’re planning to start an avocado farm, you need to know the 3 main groups of avocado trees: Guatemalan, West Indian, and Mexican. Each type has its own ideal growing range.


Guatemalan Avocados

A Guatemalan avocado is known for its hard skin that features plenty of warts.


West Indian Avocados

This type of avocado tends to flourish in warm climates. Unlike the Guatemalan avocado, a West Indian avocado has thin and shiny skin and could weigh up to 5 pounds.


Mexican Avocados

A Mexican avocado thrives well in tropical highland areas. Compared to the other avocado groups, the Mexican avocado is more tolerant of cold weather. In fact, it can manage to survive even when temperatures drop to 26˚F.

Moreover, this type of avocado produces smaller fruit that weighs less than a single pound and its skin has a distinct papery-smoothness to it.


Expert Tips on How to Start an Avocado Farm

Unless you’re willing to take on a long-term project, spend a considerable amount of money on planting, and wait for a period of 3 to 5 years for your first harvest, don’t get into avocado farming. However, if you’re willing to go through the whole nine yards to enjoy top yields for many years, check out this guide:


Tip #1: Plant them in areas where the temperatures are consistently cool

Be sure to plant your avocado trees in cool temperatures that can range between 68˚F to 75˚F on a daily basis to avoid fruit drop. However, when they’re flowering, or when they’re starting to bear fruit, the humidity levels shouldn’t go below 50% at midday.


Tip #2: They don’t like wind

In case you’re not aware, avocado trees have brittle branches that easily snap off. For this reason, it’s best not to plant them in areas that are mostly windy because wind can cause considerable damage to their fruit.


Tip #3: Most of them need proper irrigation

If your avocados are rain-fed, they need to have at least 1,000 mm rainfall spread out throughout each year. Before their flowering season, avocado trees require a drier season that lasts for about 2 months. On a weekly basis, avocado trees need about 25 mm water.

It’s extremely important to test the quality of irrigation water because if its pH and bicarbonates are really high, they trigger a build-up of free lime in the soil. You also need to remember that high levels of sodium and chloride can have a negative impact on your avocado plants.

Since the plant’s roots are shallow, the ideal way to apply water is via a micro-sprinkler or drip. This ensures an even distribution throughout the avocado tree’s root area.

Moreover, proper moisture control needs to be ensured in the root zone because this area tends to easily dry up.


Tip #4: Determine the soil’s suitability and prepare it accordingly

You can’t just plant an avocado seed on soil that hasn’t been prepared accordingly. To prepare the soil for planting, you need to dig soil profile pits throughout your farm. Make sure that the pits are 1.5 m deep.

Only a single put per ha is required. However, you need to dig more pits if the location is non-homogenous or hilly. Check the color of the soil, its texture, structure, patches, sitting water, concretions, hardpans, stones, and gravel.



Grow Your Avocado Trees in a Hobby Greenhouse!

Since avocado trees require specific levels of temperature and humidity, you’ll find it easier to grow them in a hobby greenhouse. The enclosed space allows you to customize the environment to meet the needs of your plants. What’s more, it protects them from strong winds and the constant threat of pests.

Learning how to start an avocado farm outdoors is great, but growing them inside a hobby greenhouse is even better.
