Suggestion Water Insoluble Matters Content Of Fertigation Fertilizer
Feb 07, 2017

The application of nutrients through irrigation systems is referred to as Fertigation. The incorporation of soluble fertilizers into the irrigation water is facilitated the integration and harmonization between the application of water and plant nutrients. Using fertigation, an adequate supply of nutrients and water can be directed towards the plant root zone to satisfy plant demands during the various growth stages. 

Fertigation, in any irrigation system, requires the injection of soluble fertilizer solutions into the irrigation water by a dosing devices. High quality, high water soluble fertilizers are required  for the preparation of an appropriate nutrient solutions. So, Different fertigation methods depend on the different irrigation device.


For DRIP IRRIGATION and Subsurface Textile Irrigation (SSTI), it needs fine control of the flow, so it is easily blocking the dripper with the precipitate that formed by the water insoluble matters from fertilizer and calcium and magnesium ions in irrigation water, and thus greatly affect the irrigation efficiency. 

So, suggested water insoluble matter's content of the fertilizer is not to exceed 0.1% that use for Drip Irragation & Subsurface Textile Irrigation (SSTI).

Similarly, suggested water insoluble matter's content of the fertilizer is not to exceed 0.5% that use for Sprinkle Irragation & Foliar Spraying.

The Flood Irrigation & Ditch Irrigation are extensive management and requied not so strictly, but we suggest not to exceed 5%.
