Abstract:
The biomass-based soils are
used in the ecological agriculture, being
already proposed in sustainable organic
production systems with reduced costs for
assuring the good cropping productivity, and
also high quality of the crops. For the
elimination of the synthetic inorganic
fertilizers’ utilization on soil, the use of
certain types of residual biomass in mixture
with the reference soil was proposed as they
have a positive impact on the adsorption and
absorption of nutrients and water for the
nutrition of plants. The aim of this paper is
to present four mixtures of reference soil and
residual biomass, considered as biosoil used
as support for development of wheat seeds.
These biosoils were characterized in terms of
real density, actual and potential pH, content
of total organic carbon, humus,
exchangeable calcium, total and available
nitrogen and phosphorus, and the trends of
grain seeds germination and plants growth
were registered in association with the
evolution of soil pH for a period greater than
a month. The results encourage the use of
these biosoils (mixtures of soil with residual
biomass) as support for plants cropping.
