Bi Agra™ Premium Soil Moisture Retaining Agent


THE PROFESSIONAL’S CHOICE Bi-Agra™ from SST Australia is a new generation water retaining agent that has been specifically designed for home garden use where watering-in is restricted. Bi-Agra™ is a dual action product that allows soil to accept and retain water at the root zone for longer. BI-AGRA was researched and developed in WA for our conditions. It is produced by SST Australia which is the largest supplier of commercial grade wetting agent in Australia. Application of Bi-Agra™ prolongs turf health and vigour, ensures efficient water use and increases water retention by up to 50%, at the root zone of your lawn. Note: Bi-Agra™ is not a wetting agent, it is a dual action moisture retaining agent


This unique product helps your lawn require 50% less water over summer, surviving heat & water restrictions.


Bi-Agra™ is a bi-active formula provides both outstanding penetration along with superior moisture retention. Bi-Agra™ strength is its ability to retain additional moisture in normally low water-retaining root zones. Unlike polyacrylamides which hold water tightly, Bi-Agra™ holds moisture in the soil, yet allows water availability through the normal process of osmosis as required by the roots. Bi-Agra™ should be used as a curative treatment on severely water repellent soils to assist with the rewetting of dry root zones.

BI-AGRA helps in combating water repellent problems in your lawn. It has two components, a wetting agent for spreading water evenly throughout the soil, and a moisture retaining component to hold the water in the soil. BI-AGRA penetrates dry lifeless soil and binds with its molecules. Once water is applied, BI-AGRA helps to evenly distribute the water and hold on to it, keeping it at the root area of your turf much longer than untreated soil. It is specially made to aid in the twice a week watering restrictions.

Bi-Agra™

  • Can retain up to 5 times the amount of water against the root zone compared to untreated areas
  • Is non-burning at recommended rates
  • Reduces turf wilting and moisture/heat stress
  • Is environmentally friendly
  • Is an easy hose on application
  • A 2-litre bottle treats 150 m² of lawn and garden bed

When used in combination with Aquaforce premium wetting agent, it helps keep your lawn healthy and green during Perth’s summer heat and water restrictions.


Apply Aqua Force premium wetting agent initially, leaving at least four days before applying an application of Bi-Agra™ soil moisture retainer.


Bi-Agra™ premium soil moisture retaining agent is recommended for use at the following times and should be applied at least three times a year. Turf Growers Association WA members recommend applying Bi-Agra™ at the beginning of Spring (September) and Summer (December), again in late Summer (February) and in Winter (June/July) to hold winter rains.

  • Improves water distribution and uniformity, helping to reduce that blotchy look often apparent in domestic lawns.
  • BI-AGRA is long lasting with research showing it is still effective up to 12 months after application.
  • Aids in reducing the frequency of irrigation. It is an easy hose on application that is environmentally friendly.
  • BI-AGRA can be seen working just three weeks after application.
  • It will improve your lawn’s appearance compared to an untreated lawn.
