3 Important uses of Azolla Cultivation


How to Cultivate Azolla in Cultivation Paddy Grounds

Azolla Cultivation

Azolla is an aquatic floating fern found in a temperate climate suitable for paddy cultivation. Being a dense aquatic plant, Azolla cultivation needs shallow waters in cultivation as it grows slowly, is prone to weed seedling formation. Therefore, Azolla cultivation is mostly restricted to regions where water is in a high abundance.


It is an inexpensive agrochemical. Proper agrochemicals can be used for Azolla cultivation in paddy fields and eventually in open fields. The agrochemical should be selected to match the required water retention level of the plant. A high level of nutrients can promote the growth of wild Azolla farming. The fertilizer may include:

Cereals and mineral fertilizers such as Azolla, worm fern, Azolla to, Azolla straw, Azolla wheat, Azolla trefoil, Azolla reed, Azolla wheat. If you want to cultivate Azolla on a large scale, then the quantity of fertilizer should be enough to cover up the whole of the farm field. The actual percentage of Azolla fertilizer should be proportionate to the water retention level of Azolla. Usually, the normal fertilizer should be at about 40% in a normal paddy field.

Soil, cultivation

It is a natural cultivation method, and the soil should be firm but water-bearing. C should prepare soil well by removing all the weeds, grasses, and filth. Appropriate soil preparation should be used for Azolla cultivation in paddy fields.

Azolla cultivation

Azolla needs abundant water to reach a high water retention level. In the paddy fields, the fertilizers can be used for Azolla cultivation. Even in open field cultivation, water-based fertilizers can be used, and c can prepare the fertilizers by mixing them with local water. After the production of Azolla fertilizers, the area should be irrigated by a water supply line to grow Azolla with sufficient water retention.

When cultivating Azolla in an open field, c can apply the fertilizer to the whole field. After the fertilization, the field should be cleaned and dried, and then the soil should be plucked well, washed, dried, and spread on the field. Once the cultivation is done, the crop should be exposed to the sun to dry completely. Usually, after the Azolla cultivation, c should pluck the paddy field properly. However, it is recommended to pluck the paddy fields in a fortnight in open fields so that the plant is not affected by pests, rust, caterpillar, and other insects. After the harvesting, c can keep the seed in a warm area for curing for future farming.

The cultivation process is as follows:

Seedling cultivation

C should plant the seedlings in the soil once it is dry and ready. C should water seedlings thoroughly for a week. The seedlings can be harvested within a week. If the seedlings are not picked, the weeds may choke the plant completely. The mature seedlings should be harvested and dried to protect them from herbivorous animals.

Fertilizer based cultivation

The Azolla cultivation can be carried out by fertilizers such as Azolla straw, Azolla reed, Azolla wheat. C can prepare the fertilizer by mixing them with local water. C must apply the fertilizer to the paddy field to grow all the required Azolla seedlings.

Cultivation in paddy fields

To grow the cultivated Azolla in paddy fields, the soil, fertilizers, watering, the spacing of the growing plants, the cultivation of the seedlings should be followed.

In the paddy field, c should apply the fertilizers to the entire field. C should apply the fertilizers in the shallow areas, and the fertilizers should be watered well before applying the fertilizers. Seedlings are removed after a few days.

After the seedlings are removed, the fertilizers should be replaced by the fertilizer enriched with Azolla straw, Azolla reed, Azolla wheat, Azolla stop. Then c should apply the fertilizer to the whole of the paddy field. C should irrigate the fertilizers with a water supply line to cultivate the seedlings.

After the fertilization, c should plant the seedlings in the field. C should plant the fertilizer right at the surface of the soil. Even in paddy fields, it is recommended to plant the seedlings at a depth of 2 to 4 cm to protect the young plant from dampness.

After the cultivation is done, the soil should be plucked well. Then the soil should be cleaned and dried, and then c can spread it over the field.

The process is as follows:

The whole field should be plucked well and then cleaned thoroughly. Then c should dry the soil by covering it with a clean cloth or coated with oil. The soil should be dried for 2 to 4 days, after which c can spread it on the field. After spreading, c should prepare the soil well by removing all the weeds, grasses, and filth. Appropriate soil preparation should be used for Azolla cultivation in paddy fields.

It should be kept as an open field.

C should prepare soil well by removing all the weeds, grasses, and filth. Appropriate soil preparation should be used for Azolla cultivation in paddy fields. Azolla cultivation in paddy fields should be carried out properly. Proper cultivation is necessary to cultivate Azolla to produce higher-quality seeds.

  • Azolla cultivation in paddy fields is useful to produce seeds in a shorter time.
  • Initially, the seedlings should be cultivated in paddy fields in loose vegetation.
  • After the cultivation of seedlings, the growing plants should be allowed to grow for another few weeks. Then the soil should be collected for transplanting to the paddy fields.
  • Azolla cultivation in rice fields is highly recommended for azolla production. After the cultivation of the seedlings, it is recommended to carefully cover the paddy field with a thin layer of azolla straw, azolla reed, azolla wheat.
  • Azolla cultivation in paddy fields is useful to produce seeds in a shorter time.
  • Following are some techniques that are helpful to cultivate azolla in paddy fields.
  • It is advised to use small tractor to pluck the paddy field.
  • Planting the seedlings at the depth of 2 to 4 cm.
  • After plucking, the seedlings should be planted in paddy fields.
  • The crop should be tended with the rain water.
  • After the second or third harvest, the seedlings should be plucked well and dried.

One of the commonly used chemical agents in cultivation is Azolla concentrate. As it helps in weed eradication and encourages water uptake, Azolla concentrate is widely accepted for Azolla cultivation. Another method for Azolla cultivation is artificial irrigation. The major issue with Azolla cultivation is the low cultivation efficiency.

Reduce water consumption

The cultivation of Azolla requires continuous irrigation water for the entire cultivation cycle. Therefore, farmers need to regularly check the moisture content of the soil by testing its humidity or testing its moisture content through precipitation. The cultivation area also needs to be kept free of weeds to maintain an optimal growth rate of Azolla and adequate agrochemical production. Therefore, to make Azolla cultivation efficient, farmers need to reduce the cultivation water consumption. There are many innovative ways to do this. Some of them are:

Use the combination of water-recycling techniques.

An alternative technique to promote water harvesting is porous black soil, which has a good moisture-holding capacity. Using this method, farmers can irrigate the entire field in a single watering. However, since water permeability is low in black soil, water stored in the soil immediately drains back to the ground.

Use water-saving irrigation practices.

Azolla plant also has low water consumption. Therefore, it is possible to cultivate Azolla in dry and dry-prone areas much less water-consuming. Farmers can use water-saving irrigation practices such as drip irrigation, sprinklers, and fertilizer applied on granulated in dry-prone areas. In both water harvesting and water-saving irrigation, farmers will get the maximum crop yield.

Azolla cultivation in dry areas can be achieved in a much less water-consuming manner as compared to irrigated areas. For instance, in dry regions, Azolla can be cultivated in shallow water, even on a small-scale farm. By doing this, farmers can avoid the need for regular water-saving irrigation methods. In addition to this, farmers can make use of clay-stone mix that can promote water-conserving cultivation practices. In India, farmers can use stone-salted sand, which is also known for promoting water-saving irrigation practices. However, the benefit of using a clay-stone mix is limited since these stone-salted sand grains are not available in great quantities.

Make use of monocultures

One of the most important techniques to reduce water consumption is the use of monocultures. In such monocultures, the cultivation area does not have weeds or bad plants in the initial phase. It is also possible to induce monocultures with Azolla in a non-edge aspect so that there is not much growth of bad plants in dry-prone areas.

Monocultures will result in the formation of a much more water-efficient field. As a result, farmers will need to reduce water consumption even in unirrigated areas. It will also help farmers provide good water resources to both weeds and good plants in Azolla monocultures.

Ensure that no weeds are allowed to grow.

Before planting Azolla, farmers can make sure that there are no weeds in the field. This is necessary to avoid the germination of weeds in the soil. In addition to this, it is necessary to arrange adequate protection to the germinating seeds to prevent any amount of seedling formation in the soil. After germinating, weeds cannot grow easily. Therefore, c should plant only healthy, good-looking, and easy-to-harvest seeds in the soil.

Use good-looking seeds.

Another important technique is the use of good-looking seeds in Azolla cultivation. Seeds should be kept in a field that is free of weeds. This will result in fewer weeds and a better Azolla plant and enhance water absorption from the soil. Good-looking seeds can also improve the rate of crop maturity, which increases water productivity and ensures good yields from Azolla cultivation.

Plan ahead.

Once a suitable field has been identified, farmers can plan the cultivation process accordingly. In fact, farmers can use this technique to avoid the problem of water scarcity. They can cultivate Azolla in dry regions, plan for cultivation at the monsoon time, and plan for cultivation at watering.

Once the cultivation process is decided, farmers can plan for cultivation in three steps. Firstly, they should plan the seeds which can contribute to the establishment of monocultures. In addition, they can also prepare the cultivation ponds. Next, farmers can prepare the field of Azolla at the time of water supply.

The next step is the crop harvest. By doing this, farmers can harvest the plants as soon as they are matured. In this process, farmers will get the maximum crop yield and minimize water.

  • Possible ways to reduce water consumption:
  • Surface irrigation can be used during all seasons. If the total area of cultivation is not much, the amount of water can be reduced further.
  • Once azolla is in the cultivation area, its water consumption should be limited to about 1-2 gal/day, till the plant matures.
  • Use desiccants in azolla cultivation.
  • Carefully remove any weeds in the cultivation area.

Optimal cultivation is the process of removing water from the soil in which Azolla is to be cultivated. To improve cultivation efficiency and improve yield, farmers need to consider the following factors:

Pollutants in Azolla concentrate: Besides other chemicals, Azolla concentrates are mostly diluted with pesticides. In some cases, pesticides might have a detrimental effect on Azolla plants. Therefore, farmers should carefully observe their crops for the harmful effects of pesticides.

Limited cultivation area: One of the major issues in Azolla cultivation is the limited cultivation area. Farmers need to check the extent of Azolla cultivations in their area and decide whether they are going to grow Azolla or not. If they decide not to grow Azolla, they will have to shift to other cultivation areas.

Different cultivations for different needs: Each area requires different cultivation techniques. Farmers need to understand the requirements of different areas and decide accordingly. Therefore, the cultivation of Azolla in different areas needs to be done properly.


To make Azolla cultivation effective and productive, it is important to understand the basic requirements of different growing regions. Farmers should also try to select only Azolla cultivations and crops suitable for each particular region. To get the desired yield of the Azolla cultivations, farmers need to adjust the cultivation methods based on the required water requirement and soil moisture content. Therefore, the cultivation of Azolla is not a reliable option for a paddy cultivator. Therefore, the farmers need to focus on another crop suitable for the regions where water availability is sufficient.
