SUMMARY

The objetive of this experiment was to determine the macro and microelements from 100 samples of sik grasses when they were seeding:

F. polystachia P. maximun
conjugatum A. escuparius
decumbes P. purpureum

The minerals determinated were Ca, P, Mg, K, Mn, Zn, Fe y Cu. The samplea were analized by the Atomic Absortion Techinic with my dry Calcinatio. The results were:

plystachia, Ca, 0.10, P, 0.04, Mg, 0.05, Na, 0.08, k, 0.16, aforesaid in %.
Mn, 59.00, Zn, 12.05, Fe, 2.32 y Cu, 4.12, aforesaid in
ppm.

maximun, Ca, 0.04, P, 0.04, Mg, 0,03, Na, 0.06, K, 0.09, aforesaid in %.
Mn, 44.10, Zn, 13.42, Fe, 2.32 y Cu 4.12, aforesaid in
ppm.

conjugatum, Ca, 0.09, P, 0.03, Mg, 0.04, Na, 0.08, K,
0.23, aforesaid in %.
Mn, 81.50, Zn, 8.70, Fe, 4.60 y cu, 3.20, aforesaid in
ppm.

escuparius, Ca, 0.08, P, 0.03, Mg, 0,03, Na, 0,07, K,
0,21, aforesaid in %.
Mn, 112.00, Zn, 8.70, Fe, 1.90 y cu, 1.80, aforesaid
in ppm.

decumbes, Ca, 0.06, P, 0.04, Mg, 0.04, Na, 0.03, K,
0.24, aforesaid in %.
Mn, 5.10, Zn, 4.42, Fe, 9.05 y Cu, 6.00, aforesaid in
ppm.

It was concluded, there are deficiencies in macroelements level and also Zn. This results may alow to dran schemis to mineral suplementation in ther adequete anpunts for this area.
