Fertigation, the application of fertilizers with the irrigation water, allows applying small amounts of fertilizer in each fertigation event, that contributes to high flexibility in fertigation frequency.


What is the process of fertigation?

Simply put, fertigation is a process that combines fertilization and irrigation. Fertilizer is added to an irrigation system. It is most commonly used by commercial growers. Fertigation rather than traditional fertilization approaches is purported to target the plant’s nutrient deficiencies more effectively.


What are the advantage of fertigation in agriculture?

Fertigation has some specific advantages over broadcast and band fertilization: A frequent supply of nutrients reduces the fluctuation of nutrient concentration in soil. There are efficient utilization and precise application of nutrients according to the nutritional requirements of the crop.


What are the uses of fertigation?

Fertigation is used to add additional nutrients or to correct nutrient deficiencies detected in plant tissue analysis. It is usually practiced on the high-value crops such as vegetables, turf, fruit trees, and ornamentals.


What is fertigation method of fertilizer application?

Fertigation is the application of nutrients through irrigation systems, a contraction of fertilization and irrigation to supply the plant with its daily demand of water and nutrients/fertilizers as required by its specific growth stage throughout its development.


What is fertigation PDF?

Fertigation is a recent innovative cultural method, by which fertilizers are applied along with irrigation water through irrigation system like drip to get higher fertilizer use efficiency as well as increasing the crop yields.


What is applied to crops and soil through fertigation?

Fertigation is the process of directly applying fertilizer to a crop through the irrigation system. In commercial production, drip tape is often used to irrigate vegetable crops. This can be installed either beneath plastic mulch or on the surface of the soil.


Which crop is suitable for planting using fertigation system?

Water saving, yield and profit under drip and drip fertigation systemsCropsWater Saving (%)Profit (Rs/ha)DripBanana3598000Sugarcane2947000Tomato3277000


What are the advantages of fertigation in agriculture Upsc answer?

What are the advantages of fertigation in agriculture? Controlling the alkalinity of irrigation water is possible. Efficient application of Rock Phosphate and all other phosphatic fertilizers is possible. Increased availability of nutrients to plants is possible.


Is fertigation and hydroponics same?

Fertigation is the precise application of nutrient solutions (fertilizers) through irrigation. In a contained system, fertigation is similar to run-to-waste hydroponics, where a solution is run once through the media.


Why is fertilization used?

Fertigation rather than traditional fertilization approaches is purported to target the plant’s nutrient deficiencies more effectively. It also reduces soil erosion and water consumption, reduces the amount of fertilizer utilized, and controls the time and rate it is released.


Can fertilizer spray damage neighbor’s car?

Fertigation via aerial spray nozzles produces a mist that drifts easily which may affect your neighbor’s garden as well. Also, fertilizer sprays that drift onto vehicles should be washed off ASAP. If, for instance, the spray drifts onto your neighbor’s car and is left overnight, it can damage the paint.


Can you fertilize perennials with foliar spray?

As to other perennials and annuals, fertigation isn’t the ideal fertilization method since each plant’s needs will be unique. A better idea is to apply a foliar spray or to dig in slow-release fertilizer or organic compost. That way each individual plant’s needs can be met. Printer Friendly Version.


What fertilizer is used in fertigation?

Most often, the types of fertilizers utilized in fertigation systems include: Potassium chloride. Diammonium phosphate. Monoammonium. Urea. Ammonium Nitrate. Phosphate. Thus the culmination of various fertilizers work more efficiently on certain plants and this can be executed with immense efficiency.


What is the first piece of equipment required to fertigate a plant?

In order to fertigate plants, the first major piece of equipment required in this process is the establishment of an irrigation system. If an irrigation system is already in place, it’s vital to ensure that there is a backflow preventer installed so as to prevent the contamination of the water source with fertilizers.


What is chemigation in irrigation?

Although chemigation and fertigation are used interchangeably from time to time, the fact is that chemigation is purely related to the use of chemicals such as fungicides, insecticides, and herbicides. In fertigation, however, the only additions made to the water in the irrigation line is the addition of nutritious fertilizers.


What is the process of fertilization?

Fertigation has been developed after a process known as chemigation that also relies on the existing irrigation line in order to offer nutritious chemicals to the produce.


How does fertilizer save time?

Time Saver. As the fertilizers are directly injected into the irrigation line, it hardly takes any time to evenly distribute the nutrition for similar crops across the field. This ends up saving a lot of time and effort for farmers.


Why is fertilization important?

Fertigation systems have an extremely specific purpose and can be doubly useful when it comes to offering water and nutrition to large, uniform fields. Once it becomes possible to control the flow of nutrition based on the requirements of the plants, the potential for this system will become near-limitless as well.


How does fertilizer affect agriculture?

Some of the ill effects of fertilizer use on farmlands include the depletion of oxygen levels in the water table and excessive growth of weeds and algae.

Overview


Uses

Fertigation is practiced extensively in commercial agriculture and horticulture. Fertigation is also increasingly being used for landscaping as dispenser units become more reliable and easier to use. Fertigation is used to add additional nutrients or to correct nutrient deficiencies detected in plant tissue analysis. It is usually practiced on the high-value crops such as vegetables, turf, fruit trees, and ornamentals.


Commonly used nutrients

Most plant nutrients can be applied through irrigation systems. Nitrogen is the most commonly used plant nutrient. Naturally occurring nitrogen (N2) is a diatomic molecule which makes up approximately 80% of the earth’s atmosphere. Most plants cannot directly consume diatomic nitrogen, therefore nitrogen must be contained as a component of other chemical substances which plants can consume. Commonly, anhydrous ammonia, ammonium nitrate, and urea are use…


Advantages

The benefits of fertigation methods over conventional or drop-fertilizing methods include:
• Increased nutrient absorption by plants.
• Accurate placement of nutrient, where the water goes the nutrient goes as well.
• Ability to “micro dose”, feeding the plants just enough so nutrients can be absorbed and are not left to be washed down to storm water next time it rains.


Disadvantages

• Concentration of the solution may decrease as the fertilizer dissolves, this depends on equipment selection. If poorly selected may lead to poor nutrient placement.
• The water supply for fertigation is to be kept separate from the domestic water supply to avoid contamination.
• Possible pressure loss in the main irrigation line.


Methods used

• Drip irrigation – Less wasteful than sprinklers. It is not only more efficient for fertilizer usage, but can also be for maximizing nutrient uptake in plants like cotton. Drip irrigation using fertigation can also increase yield and quality of fruit and flowers, especially in subsurface drip systems rather than above surface drip tape.
• Sprinkler systems-Increases leaf and fruit quality.


System design

Fertigation assists distribution of fertilizers for farmers. The simplest type of fertigation system consists of a tank with a pump, distribution pipes, capillaries, and a dripper pen.
All systems should be placed on a raised or sealed platform, not in direct contact with the earth. Each system should also be fitted with chemical spill trays.
Because of the potential risk of contamination in the potable (drinking) water supply, a backflo…
