Kenya — capsicum and tomato under glass

Humate alone against the recommended rate of DAP fertiliser. Germination went from one in ten to ten in ten.

Glasshouse trials in Kenya in 2024 recorded substantial yield gains in tomatoes and peppers. The capsicum replication below sets the positive control — di-ammonium phosphate at the recommended rate — against plots given nothing but extract.

Note what this trial does not use: no , no . This is the liquid extract alone — the part of the system that fits in a container and ships anywhere.
