The percentage of arsenic that may be lixiviated
and mobilized is <in agricultural compost (3%) than urban compost USRC3 and USRC6 (20-30%).
The liberated compounds are lixiviated
and deposited and then, they act as cementing substance (free silica, calcium carbonate) in the soil.
So politics, class, and religion were lixiviated
with fears of vulgar sentiment.
Aerial and root biomass, pH and cation-exchange capacity (CEC), N[H.sup.+.sub.4] in the substrate and lixiviated
N[O.sup.-1.sub.3] were evaluated.
The experiments were conducted at the National Institute of Agricultural Sciences, Cuba, on a lixiviated
Red Ferralitic soil (Udic Rhodustalfs); treatments consisted in inoculation and/or coinoculacion with micorrhyza and rhyzobacteria, under different nitrogen fertilization dosages.
Powdery mildew in roses by applying lixiviated
plantain raquis compost.
Between these two horizons, an illuvial horizon is formed, called albic, generally shallow and highly lixiviated
or leached (see also vol.
In this context, the biological nitrogen fixation (BNF) assumes great importance, for it represents a viable alternative for nitrogen supply to the crop, due to low costs for the grower and both the prevention of contamination of water resources by the lixiviated
nitrate and the reduction of emission of greenhouse effect gases (GRANGE et al., 2007; PELEGRIN et al., 2009).
The increase in Ca and Mg concentrations during the aging process may be due to these elements not being easily lixiviated
. Nevertheless, different limestone effects on Ca concentrations were observed between the two areas.
