In simple words, fertirrigation is a technique by which fertilizer are applied with the water of the irrigation system. This way, the producer takes advantage of the irrigation system to add to the plants the nutrients they need. Its name comes of combining the words “fertilization” and “irrigation”.
There are 2 different types of fertirrigation: the quantitative and the proportional. The quantitative fertirrigation studies the nutrition needs considering some variables like the number of plants, the age, the foliar surface, the type of soil, the planted area and others. After analyzing this data, the nutritional requirements of the crop can be known ad according to them the fertilizers are added to the irrigation system. This is a more traditional system.
On the other hand, the proportional fertirrigation is a technique that is more used in crops without soil or hydroponic. In this case a determined quantity of fertilizers is added to a determined quantity of water to get the required concentration to achieve a correct fertilization in plants. The calculation is made in grams per liter or in liters per cubic meter.
Because of the importance that rational use of water has today, fertirrigation appears as a very complete solution to take care of this resource and optimize it to the maximum in agriculture. Also, with this fertilization technique, producers can save not only water; they save money in fertilizers too.
