Resumo(s)
Animal manure management is a real challenge to minimize environmental impacts and
ensure that this valuable material is efficiently used in a circular economy context. One of the main
limitations for larger use of animal manure as fertilizer is the availability of land to receive it in an
area close to the farm. Indeed, animal manure is traditionally used for cereals and animal feed growth,
but the soil area occupied with these crops might not be enough to receive all the manure produced
and/or part of this soil might have nutrient contents, namely phosphorous, that do not permit further
application of manure. Hence, extra land used for other agricultural activities might be an option.
The main objective of the present review was to analyse the constraints and solutions to increase the
use of manure in horticulture and orchards. Emphasis was given to the legal framework for manure
utilization in the EU that might stimulate or restrain such a solution. The main characteristics of
manure that might limit or stimulate manure reuse were also described, and the potential of some
treatments to valorise manure was analysed. Several examples of alternative uses of manure in
horticulture and orchards were examined, and the society and farmers’ acceptance of the proposed
solution was addressed
