P.X. Farms has a longstanding relationship with precision farming specialist SOYL, and we have exploited soil analysis combined with nutrient offtake data to establish soil, status and direct variable rate applications where necessary.

We still study the data and will use analysis when taking on a new tenancy, as well at the end of its term, or for contracts, to document soil quality improvements,” explains James.

However, we are moving increasingly to blanket applications of lower costs product. Variable-rate application is still appropriate for higher-cost treatments. By standardising treatments, we can aim for meaningful measurements.

The aim is to increase indices with a target of 2+, and each field receives nutrients every year. “Sulphur has an increased influence, and we are carrying out sulphur trials. Due to the enforcement of the Clean Air Act, we will need to supplement sulphur on crops such as brassicas.”

Nutrient sources are also carefully considered – Limex, Fibrophos and Gypsum are all used.

James says: “Fibrophos is heat-treated chicken manure which has no odour, so is more socially acceptable in built-up areas and helps avoid nitrate vulnerable zone (NVZ) issues. We also like products that can be stored outdoors and spread in summer.
