Cereals 2006 : Growing demand for soil mapping

The rising price of fertiliser was a key driver behind increased uptake of Soilquest’s field mapping service, according to the firm’s Tom Parker.

Based on measuring soils’ electrical conductivity at depths of 30cm and 90cm, the system determined the phosphate, potash, and magnesium levels and pH status and offered recommendations based on the findings, he explained.

“Personally, I don’t believe people do enough to look at the deeper soil profiles, which plant roots can still reach.”

It was still “early days” as far as providing nitrogen advice based on the system, he admitted.

Growers were keen to receive more advice on maximising nutrient uptake.

Environmental and economic pressures were the main drivers.
