RB209 & FACTS Alignment

RB209 is the UK framework used to:

• Calculate crop nutrient requirements

• Account for soil type, previous crop and rainfall

• Set nitrogen recommendations

Most fertiliser plans already start with RB209 — and so does Triplex.

RB209 does a good job of:

• Setting sensible baseline nitrogen rates

• Preventing under-application

• Supporting regulatory compliance

Triplex does not argue with this.

Item descIn practice, many fertiliser plans:

• Focus on applied nitrogen only

• Treat soil nitrogen as background

• Judge performance on yield alone

This can hide inefficiency, because:

• Soil nitrogen still feeds the crop

• Total nitrogen supply can exceed crop uptake

• Losses occur even in good-looking crops

Triplex exists to make this visible.

Triplex uses RB209 as the starting point, then goes one step further.

It:

• Uses RB209 to calculate baseline requirements

• Properly accounts for soil-supplied nitrogen

• Looks at total nitrogen available, not just what’s spread

• Helps match supply to realistic crop uptake

This improves efficiency without breaking the rules.

Triplex is designed to be delivered through:

• FACTS-qualified advisors

• FACTS-aligned nutrient planning

It supports FACTS principles by:

• Improving nutrient stewardship

• Reducing unnecessary losses

• Supporting defensible recommendations

• Providing clearer evidence for decisions

Triplex does not override advisor judgement — it supports it.

Triplex supports:

• Sensible nitrogen use

• Reduced loss risk near watercourses

• Better reporting and justification of decisions

• NVZ and stewardship objectives

For farmers, RB209 and FACTS alignment means:

• Confidence decisions are compliant

• Reduced risk in inspections or audits

• Clear reasoning behind fertiliser spend

• Better understanding of where money is lost

Triplex helps turn compliance into better value, not just box-ticking.
