Soil samples from sugar cane fields in Colombia were analyzed using physical-chemical analysis, X-ray diffraction (XRD), and Mössbauer spectrometry (MS) to identify mineral phases present. Quartz was found in all samples by XRD. MS also identified iron-containing phases belonging to Fe2+ and Fe3+. MS serves as a complementary technique to XRD for agricultural soil analysis since soils contain iron that can be analyzed by MS.

Methods & Materials
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 Tolima. The
spectra were refined and
adjusted using the program
special.

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
