Dynamic Lifter fertiliser
1972
organic fertiliser made from chook manure

In 1969 Norm Jennings realised that while chooks couldn't lay golden eggs, the stuff at the bottom of the cage was almost as good. It took another 15 years to work out ways to convert chook poo into Dynamic Lifter, a fertiliser that's easy to package, transport and use.

To keep the droppings as dry as possible, he redesigned the birds' drinking trays to stop water from splashing onto the floor. He then used his engineering skills to develop machines to cure and sterilise the droppings and turn them into pellets, and that's the secret of Dynamic Lifter's international success. The catchy name was devised by Norm's wife and business partner, Nadia.

The company negotiated agreements with poultry farmers in the region around each of the factories. In return for a contract to buy chicken droppings, the company installed its patented equipment in the farmer's sheds. Farmers benefit from the arrangement because Dynamic Lifter's drinking system for chickens keeps the manure dry and eliminates pollution and blowfly problems. The company collects manure from each of the farms on a regular basis and trucks it to the factory site to be cured and processed.

Field trials in the 1970s demonstrated the outstanding success of Dynamic Lifter, and it was sold in bulk to farmers and orchardists. In the late 1980s bagged pellets began selling in supermarkets and plant nurseries to home gardeners. Dynamic Lifter is made under licence in the USA and exported from Australian factories to Asia, Europe and the Middle East.

In 1995, the Jennings sold their technology and rights to Dynamic Lifter for $18.8 million.
