Influence Of Agrarian Residuals Evaluated As Bio Fumigation In The Fertility Of The Soil

The research was carried out in lab conditions in the Center of Environmental Sciences of the Superior Council of Scientific Investigations (CSIC) in Madrid Spain. Soil analisys were made in samples submitted to biofumigation process with different agrarian residues. The soil parameters determined were: nitrogen (N), pH, electric conductivity (EC), phosphorus (P2O5), potasium (K), calcium (Ca), sodium (Na), magnesium (Mg), iron (Fe), manganese (Mn), zinc (Zn) and copper (Cu). Results obtained showed that in general case treatments presented significative differences considering the control pattern, showing increasement in various of the studied elements.
