Why use grain analysis?

Acquiring and utilising accurate information such as grain analysis data is fundamental to many decisions made in the arable sector.

Making nutrient decisions based on analysis of harvested grain is becoming an increasingly useful management tool.

Grain analysis is available for both cereals and oilseed.

Grain analysis is the best way to determine if the nutritional requirements of a previous crop were properly addressed.

What to analyse? 

Testing the nutrient content of harvested grain provides you with:

  • Accurate measurement of nutrient take-off (as opposed to relying on standard RB209 book values for P&K).
  • The opportunity to identify any nutrient deficiencies in the harvested crop that may have impacted upon its success (e.g. N:S ratio and critical P levels).
  • Information to incorporate into future nutrient planning for the following crops (e.g. micronutrient fortification and improved management of future soil fertility by maintaining P&K levels).

All results are interpreted against Yara Analytical long-term UK grain dataset allowing you to benchmark your samples against standard UK practice.

What analyses are available?

Grain N:S ratio

This is the basic analysis, useful for benchmarking nitrogen and sulphur management.

N, S, NS ratio

Grain broad spectrum 

This gives the nutrient levels for all twelve plant nutrients and ensures no deficiency is missed.

N, P, K, Ca, Mg, S, B, Cu, Fe, Mn, Mo, Zn
