WETTING AGENT
What is
?
H2Flo is a concentrated formulation of the latest surfactant technologies available, H2Flo leads the way as a wetting and water conservation agent. Once it is mixed with water, H2Flo reduces the surface tension, allowing water to penetrate the soil by spreading across the soil particles. It promotes both vertical and horizontal movement of the water, including in a range of soils, leading to more uniform distribution in the root zone.

H2Flo can be applied all year round, by drip, centre pivot and overhead irrigation. (If applied via a boom sprayer please consult your local ICL Speciality Fertilizers adviser or dealer.)
• Save up to 25% water without reduction in yield - H2Flo significantly reduces irrigation requirements* • Can be used in conjunction with fertilizers** • Readily absorbed by all types of soil • Is effective through the soil and substrate, not just the surface • Improves water penetration and improves horizontal and vertical water movement • Flexible application and flexible water rates • H2Flo is a residual in the soil and aids rewetting cycles * Proven in official trial stations, please contact ICL for more details. ** Subject to compatibility with fertiliser, where compatibility information is not available a jar test is recommended.

Getting more from your water with H2Flo why we need a wetting agent H2Flo breaks the surface tension of water and negates preferential flow of water ° ° Wetting Agent
Non-polar
• When H2Flo is added°to the water, the water is °no
° • Water is di-polar with positive and negative ends ° • Water is repelled by hydrophobic conditions causing problems with water penetration and run off
°
Water
longer repelled by the soil, increasing penetration, reducing water logging and run off and increasing water around the root zone of the crop
• The non-polar portion of the wetting agent bonds
with non-polar hydrophobic conditions, whilst the polar portion bonds with the water providing a link

Water with H2Flo
The importance of water wetting and water conservations agents Low infiltration and puddling can lead to both runoff and evaporation which results in inefficient water use. The high surface tension of standard water can limit infiltration and also leads to preference flow when infiltrated, particularly into the soil. In such situations, the soil can easily become dry and extra water is needed to properly wet the soil to avoid yield losses. This could lead to increased irrigation costs for water, energy and labour.

Trial set up Objective: Analyse yields on potato crops treated with H2Flo and standard irrigation Location:
UK/Lincolnshire
Crop:
Potato cv. Eurostar
Application method:
Irrigation with drip tape
Planting date: 12 May 2017 Treatments:
H2Flo applied:
27 May, 12 June, 25 June and 18 July
Soil type:
Sandy loam
Assessments: Yield, Marketable Yield & Tuber Numbers
Standard practice
Total Yield
The water was supplied via irrigation system without the usage of any water conservation agents. Treatment: 100% irrigation
H2Flo The addition of H2Flo in the irrigation system was done weekly between May and July. Treatment: 100% irrigation + H2Flo 8.35 t/ha increase in total yield with H2Flo application.
Application of H2Flo: Initial application of 1.2ltr/ha, followed by 3x 0.6ltr/ha for the remainder of applications
