What is the database?

• A repository of all available* and scientifically valid N, P, K and S response trials for cereal, oilseed & pulse crop species (public and commercial trials)

• Database is aimed at advisors, fertiliser companies and researchers

• Accessible online to registered users through the BFDC Interrogator tool

• Tool used to derive soil test interpretation criteria

Who is in command of soil testing?

• The soil chemist? Refine the soil tests

• The agronomist? Get better meta data

• The statistician? Minimise error in both axes

by both of the above.

Therefore in MPCN II/BFDC II……

• We will fill the NPKS response gaps in the

BFDC National Database

• We will collect appropriate meta data for those trials (soil type, soil depths, weather,

agronomic management)

• We will test a range of appropriate soil tests

• We will add LTE’s to the database
