Fertigation

The term Fertigation is used to describe a fertilizing method that improves fertilizing practices for residential and commercial use. Traditional methods of applying granular fertilizers and other chemicals including herbicides and pesticides can have a negative impact on the environment. The benefits of Fertigation over traditional broadcast or drop fertilizing methods include:

  • Increased nutrient absorption by turf and plants
  • Reduction in the use of fertilizers and chemicals
  • Reduced water usage

Fertigation units dispense fertilizers through the irrigation system. The benefits are scientifically proven, and the units are easy to install and operate. Fertigation units are also virtually maintenance free, making them the smartest choice for plant heath care.

The traditional method of fertilizing is to use a drop/broadcast spreader which can lead to an uneven application of granular or dust fertilizers. Once a granular fertilizer is applied the irrigation system waters in the fertilizer. This can result in an uneven nutrient delivery due to the uneven dissolving of the fertilizer granules. Therefore the concentration of fertilizer reaching the roots is dependent on the amount of water required to dissolve the fertilizers.

Liquid fertilizers have a significant advantage over granular applications in that liquid fertilizers can be absorbed through the above ground pores of the leaf, stalk, and branch structures of plants (Foliar absorption) as well as through the roots systems. The liquid fertilizer making its way to the root system is more consistent since it is already dissolved and ready for the plant to absorb. Making the nutrients available to both the leaves and roots greatly enhances the plants ability to receive the nutrients.

Applying fertilizers through an irrigation system works in harmony with a plants natural nutrient absorption and growth process. Using Fertigation systems, the water taken in by the plant leaves and roots includes fertilizer nutrients. Studies have proved that by applying liquid fertilizers 95% of what was applied may be used by the plant. Similar amounts of granular applications, only 10% was used. This means that 10 times the amount of fertilizer is needed to accomplish the same results realized by using a Fertigation system. This result is a significant cost savings as well as a reduced chance that fertilizers applied will find their way into streams, ground water, or the ocean.

By improving plant health, Fertigation reduces the need for pesticides and fungicides. Stressed or unhealthy plants act as magnets to pest populations. Optimal nutrient levels result in substantial reduction of disease. This in turn reduces the need to apply pesticides or fungicides. Applying a small metered amount fertilizer maintains the nutrients required by plants to be healthy.

Fertigation is an easy method of making a difference in the struggle to do more with less. Water usage may be reduced by up to 48% by having plants with a stronger root system. Increasing the root’s mass gives the root more surface area in the soil which increases its ability to absorb water and nutrients.

Through drastically increased absorption rates with Fertigation, plants and turf are healthier using less fertilizer and water. This is the next logical step in irrigation technology and can have a major impact on the environment and our quality of life.
