Purchasing and licensing - Additional data

Additional data available

The team behind the PPDB, BPDB and VSDB websites, also hold additional data relating to several chemical properties. The data held covers:

Soil degradation: The more detailed data covers DT₅₀ by soil type, pH and organic carbon for both lab and field studies (where such data is available).
Soil adsorption: The more detailed data includes K_oc/K_foc plus related parameters, by soil type (sand/silt/clay distribution as well as structure type), pH and organic carbon content.
Plant matrix degradation: The more detailed data includes DT₅₀ by crop/plant/tree type and matrix (fruit, leaves, foliage, rind, peel, tuber, etc.).

This data can be purchased either in a stand-alone format or as an addition to the full PPDB (at a 40% discount), so:
