In soil samples disoriented

sugarcane grown in the Valle

del Cauca-Colombia, were

measured by Mössbauer

spectroscopy analysis of the

mineral phases in the presence

of iron ore (Fe), belonging to Fe

2 and 3. We confirm that the MS

is a complementary and valid for

the analysis of agricultural soils

technique. Some of these same

phases were determined by X-

ray also.

The Mössbauer spectrometry

serves as an additional

technique for the analysis of

agricultural soils because soils

are rich in iron and Mössbauer

spectroscopy determined

phases containing iron.

Quartz was the mineral that was

present in all samples when he

applied the technique of X-ray

diffraction (XRD) also found this

technique other minerals such

as andesine, illite

Introduction Samples disoriented soils were

taken from the productive layer

(horizon A) of agricultural soils

cultivated with sugar cane in the

department of Valle del Cauca

and Northern Cauca, taking into

account the specifications of the

Colombian Agricultural Institute

(ICA), The Physical analysis -

Chemicals samples were

performed in the laboratory of

soil (Laserex) of the University

of Tolima, following procedure:

drying at room temperature,

sieved in 0.2 mesh and treated

by the technique of bouyoucos,

these were analyzed on a

diffractometer X ray of internal

working group of the national

soil Agustin Codazzi laboratory,

which allowed us to identify

phases present and calculation

of lattice parameters of the

phases present in soils. The

diffractograms were fitted using

the Rietveld method which

allowed the measurement of the

lattice parameters. The analysis

of electronic and magnetic

properties of these phases

containing iron (Fe), they were

measured with Mössbauer

spectrometer of Materials

Science Group, University of
