11% DTPA Iron Chelate
Orders are lodged with Australia Post every Monday, Wednesday & Friday OR unless otherwise arranged with Rob
Iron is an essential element required for plant growth. The iron demand of plants in an aquaponics system can at times outstrip the amount available from the waste provided by the fish so may need to be supplemented.
DTPA Iron Chelate is readily available for plant uptake in system water of a pH of 6-7.5, which is in the pH range of a balanced aquaponics system (pH 6.5-7) & is available in 250g & 500g packets & comes with application scoop.
Email Rob for prices on larger orders.
An iron deficiency is easy to identify as iron is an immobile element meaning that the plant can't move it around internally like nitrogen & magnesium. An Iron deficiency will have your plants displaying interveinal chlorosis (yellowing between the veins of leaves) of young leaves at the growth points.
Suggested Application Rate
It is suggested that iron levels be maintained at levels between 1-2ppm for optimal plant health in aquaponics systems.
Test Kit for Iron can be found here.
10g of 11% DTPA Iron Chelate in 1000L of system water will raise iron levels between 0.5-1ppm.
Pre mix with some system water & add under water inlet of grow bed for better distribution to plants roots.
