Results
Results are read within the conditions of the cowpea pot experiment. The page presents attributable conclusions and states plainly what has not yet been published.
A balanced summary
What the study states
The report states that plants died in the two direct milk-powder treatments at 5% and 10%.
Project research report — plant results and discussion
The report notes improvement in some chlorophyll indicators and leaf count with the biochar treatments, with response differing between formulations.
Project research report — plant results and discussion
There is no uniform superiority across all indicators, and some dry-weight measurements are lower.
Project research report — plant results and discussion
The report summary favours the ophiolite formulation overall, then palm leaves, then cow manure. This is a general ordering and does not mean superiority in every indicator.
Project research report — conclusion and future work
The results relate to a pot experiment on cowpea. Testing further crops, soils and conditions is a research extension that needs data.

How we present what we do not know
ND — not detected
No value above the detection limit was observed. ND is never converted to zero in a table, chart or average.
Not available
The value is not published in an approved version. It is not replaced by an estimate.
SPAD
An instrument index reading, never presented as a chlorophyll percentage.
Formulations included in this reading: Milk biochar with ophiolite · Milk biochar with palm leaves · Milk biochar with dried cow manure
