JS Tech has launched a new granular starter fertiliser with a relatively high sulphur content, said to optimise N uptake.
Super Start, which contains NP 10:35, 2% MgO, 5% S + 2% Zn is drilled into the soil next to the seed. It has granules of between 0.5-1.2mm and a surface area said to be 300 times that of conventional starter fertilisers such as DAP and MAP, making it quickly available to the growing seed.
Application rates are low, at 10-25kg/ha for cereals and oilseed rape, as accurate placement means less is needed, bringing benefits in terms of run-off and cost benefit, says JS Tech’s Duncan Andrews.
For maize and sugar beet, fertiliser requirements using Super Start are 15-30kg/ha and 15-35kg/ha, respectively.
