Aquagrain™ an organic based plant food which can absorb up to 30 times its mass in water.

Aquagrain enables plants to be grown in free draining sandy soils using a fraction of the water that would ordinarily be required.

In its standard format, Aquagrain is a sterile, organic slow release soil improver with a Nitrogen, Phosphorus and Potassium (NPK) value of 5.4-6.6-4.2. It is pH neutral and has substrate binding properties.

Because it is an organic based cross linked polymer granule it has the ability to hold any number of additional ingredients required for different crops or substrates. The NPK values can be enhanced, the super absorbent ratio can be increased and acid or alkaline can be added to alter its pH value.

Trials conducted at the National Institute of Agricultural Botany (NIAB) confirmed Aquagrain’s properties for extending the wilting point of plants.

Tomatoes were grown in sandy soil where the plants were irrigated normally until mature and then irrigation was ceased.

After 9 days under water stress the plants without Aquagrain had reached permanent wilt point but the Aquagrain plants continued to grow, thrive and fruit.

Trials at Delta T, a company which specialises in instruments for environmental science, including agronomy, plant physiology, eco-physiology and soil moisture, conducted a simple demonstration to show Aquagrain’s ability to absorb liquid, maintain soil moisture and reduce leachate.

Delta T PR2 Probes were buried in sand columns with and without a 1% Aquagrain layer of sand and connected to a GP2 Data Logger, taking 30 second interval readings. 1L water was added to each sand column and drainage water collected.

DeltaT Aquagrain Column Trial 60 Hours Cropped

After 2½ days most of the water had drained to the 40cm sensor and below with low moisture levels (under 10%) for each of the sensors in the top half of the profile in the sand column.

In the Aquagrain column most of the moisture was held in the top half of the column, with relatively little being measured at 30cm and 40cm.

Benefits of Aquagrain

  • Aquagrain enhances plant growth rates by 20% in good quality soil
  • Aquagrain is ideal for sandy soils, allowing plant growth in substrates as poor as builders sand
  • Aquagrain reduces the need for irrigation by up to 50%
  • Aquagrain retains it water absorbing qualities for up to 60 months before completely breaking down with no residual toxicity
  • Aquagrain slow releases soil improver over 4 to 6 months
  • Aquagrain reduces leachate reducing the amount of soil improver needed on first and subsequent applications
  • Aquagrain is a combination soil improver reducing the number of separate applications a farmer needs to make, as well as being a cheaper product than other combined crop treatments
  • Aquagrain can be applied using standard farming machinery
  • Aquagrain increases soil stability
  • Significant CO2 reduction through reduction of fertilising and irrigation operations
  • Significant NO2 reduction through reducing the amount of fertiliser farmers need to use
  • Significant reduction in irrigation requirements
  • Allows economic crop growth in unfertile lands
  • Significant reduction in fertiliser leachate
  • Does not create soil salinity like other agricultural super absorbers
  • Completely breaks down with no residual toxicity
  • Increased soil stability
  • Can assist reverse desertification
  • Increased Bio security by eradicating Prions
  • Significant CO2 reduction by avoiding animal waste incineration
  • Aquagrain increases crop yields
  • Aquagrain reduces farmers fertiliser costs
  • Aquagrain reduces farmers irrigation costs
  • Aquagrain reduces farmers operating costs
  • Aquagrain can provide considerable profit margins when compared with other fertilisers, soil improvers and plain super absorbers on the market
  • Aquagrain manufacture uses commonly used production technology which could utilise existing facilities in the country of distribution
