- •
Spatio-temporal dynamics of pig manure-derived P reacting with soil were monitored.
- •
Over time, P availability in manure solids decreased, but increased in manure char.
- •
CO2 respiration in manure solids-amended soil was higher than in char-amended soil.
- •
Both, manure solids and char derived P remained very localised P sources.
- •
Hence, high P uptake efficiency depends on manure or char placement close to roots.
