New fertiliser – made from used batteries – to hit the market
A company in Finland has developed a new type of zinc and manganese-based fertiliser – made from ordinary, everyday alkaline batteries.
The multi-nutrient fertiliser is known as ZM-Grow, and will hit the market in the UK and Ireland this month.
It has been developed by Tracegrow in the northern European country, and will be distributed here by Norfolk-based fertiliser provider Badger Consultants.
According to Badger Consultants, this is the only process through which this can be achieved at the necessary level of purity for application as a fertiliser.
“The result is a highly flexible liquid fertiliser containing key nutrients for a wide variety of crops,” according to David Harrod, owner of Badger Consultants.
Tracegrow’s UK partners highlight that zinc deficiency is observed in 10% to 15% of field crops in the UK – often on sandy soils with with both a high pH and phosphate status – while manganese is the most common micronutrient deficiency.
Sugar beet, cereals – particularly barley – and peas are all prone to these deficiencies, the consultancy group explains.
Tracegrow recommends testing soils or crop leaves before deciding on application timing and concentration levels.
Depending on a number of factors – including crop type, requirement and agronomists’ recommendations – it is recommended that two to three litres should be applied per hectare.
Trials in Finland in 2017 found a 350kg/ha increase in wheat yield, and 900kg/ha in barely, from a single application of the fertiliser.
The product is certified as an organic fertiliser, in accordance with EU regulations.
Badger Consultants is the sole distributor for ZM-Grow in the UK and Ireland, and is making the product available for delivery in 10L containers or 1,000L intermediate bulk containers.
