During the last decades, there has been an increase in population, with
increased food production, and a concentration of inhabitants in cities. This fact has
led to an increase in the generation of organic waste of urban, agricultural and
livestock origin, which requires adequate management that allows the recycling of
the waste generated. In this sense, composting can be a feasible treatment to recycle
this waste, and, therefore, improve its properties for agricultural use. Thus, the
objective of this study was to evaluate the effect of the type of manure during its cocomposting
with organic waste of municipal and agricultural origin from the
northwest of the island of Gran Canaria, for the subsequent use of the compost
obtained as organic amendment in soils or as a substrate for soilless cultivation. For
this, three types of manure were used: chicken manure, goat manure and cow
manure, which were subjected to a co-composting process mixing them with plant
residues from municipal gardens and agricultural crop residues, in the following
proportions (on fresh weight): 37.6% straw + 32.7% manure + 29.7% pruning. The
composting system used was an open dynamic system of overturned rows, forming
three trapezoidal piles 1.5 meters high x 2.5 meters wide and 16 meters long. During
the composting process, the evolution of temperature, humidity and different
physical-chemical and chemical parameters were studied, and the agricultural value,
sanitation and maturity of the compost obtained were also evaluated. The results
obtained showed that the three piles achieved adequate sanitation according to the
thermal requirements established in the regulations (temperature ≥ 60oC for at least 7 days) and a final product or compost suitable for agricultural use was obtained
