This is an interesting articel i abstract from http://www.amiad.com.
In the late 1970's, a new concept materialized To serve the international farming community: fertigation. A natural step forward in agricultural technique, fertigation (from the words fertilizer and irrigation) is an effective method of applying chemicals and fertilizers To crops via the existing irrigation system. The need For fertigation derives from the fact that traditional methods of fertilization are only partially effective and leave a lot To be desired. At the time the fertilizer is distributed, it may be too strong For the delicate roots of the young saplings, causing Then irreparable damage. Or on the other hand, it may be too weak, and thus useless. Most important however, is the fact that spread or sprayed fertilizer remains near the surface, hardly reaching the root tips and root hairs - the points of greatest absorption.
In the process of fertigation, fertilizer is applied directly with the irrigation water. Therefore, wherever the water goes, the fertilizer goes with it. Fertilizer is applied only where needed, and in the proper quantities.
The obvious advantages of fertigation, therefore, are the saving of labor and machinery, and the efficient use of the costly chemicals and
fertilizers To be applied. In fertigation, the extra activities involved in the separate application of fertilizer are no longer necessary; neither
is the purchase of maintenance of dedicated equipment For fertilizer distribution.
Additionally, such machinery often compresses the soil and
may cause crop damage. In conclusion, one might say that fertigation is the most effective and least expensive way of proving nutrients To
growing field crops.
