Abstract
Composting is a traditional method of waste treatment that means a stabilization
of organic matter to be applied to soil. Compost is used in soils as organic
amendments but it is necessary to find new properties for compost to increase its
value. One research field that is increasing is its potential use to control plant
pathogens, giving an important value as biofertilizers and biopesticides in
ecological agriculture where no chemicals can be used. Our research is focused
on the potential action of compost as an alternative to chemical disinfection with
methyl bromide by biofumigation-solarization (application of fresh compost to
soil covering with a plastic, and leaving to raise soil temperature); it is also
shown that the green compost controls fusiarosis wilt on melon plants,
demonstrating that the effect is caused by biotic and abiotic factors. Future trends
are also commented, where it is necessary to delve into the potential uses of
compost because it is necessary to develop new demands to open markets for
compost, demonstrating their beneficial effects on many aspects such as
biofertilizers, biopesticides, etc.
Keywords: biofertilizers, biopesticide, composting process, biofumigation,
solarization, plant pathogens.
1 Present and future of compost
The European Community policy is to reach the zero waste and this is obliging
to reutilize the different wastes. The organic waste has to be reutilized by their
use in agriculture, converting it from waste to resource. The most important pool
of organic waste are from agriculture (80%) and the urban life (10%). The
organic matter from different waste can be used as organic amendments but it is
necessary to stabilize them by composting process. The composting process is a
