Fertigation is the application of fertilizers, soil amendments, or other water soluble products through an irrigation system. Chemigation, a related and sometimes interchangeable term, is the application of chemicals through an irrigation system. Chemigation is considered to be a more restrictive and controlled process due to the potential nature of the products being delivered to cause harm. Therefore it is generally more regulated than fertigation. Fertilizers are chemicals given to plants with the intention of promoting growth; they are usually applied either via the soil or by foliar spraying. ... Impact of a drop of water. ... High-altitude aerial view of irrigation in the Heart of the Sahara ( ) Irrigation is the replacement or supplementation of rainfall with water from another source in order to grow crops or plants. ...
Fertigation is used extensively in commercial agriculture and horticulture and is starting to be used in general landscape applications as dispenser units become more reliable and easy to use.
Benefits of fertigation over traditional broadcast or drop fertilizing methods include:
A high root density is found in these fertigation bulbs and it is crucial to ensure optimum growth conditions in terms of nutrient and water supply.
The yield increase in fertigation systems is in line with the need to intensify land-use-efficiency to meet the food demand of the growing population by production on a shrinking acreage of available arable land.
Fertigation opens new opportunities to optimize plant nutrition, and Yara is investing in research to optimize fertigation recommendations and to improve the understanding of the nutrient dynamics in fertigation systems.
