In order to study the dynamics of physicochemicals components of water
obtained from lagoons situated on physiographys of "bancos,
bajíos y esteros" that serve as watering places for cattle,
samples from savannas of Mantecal, Apure state, Venezuela were taken
and measured between march −2005 to april − 2007. Results
showed proverty of mineral elements for adecuate mineral nutrition, low
electric conductivity and slightly acids pH, which in periods of
draught had a tendency to neutrality. Sodium, potassium, calcium
cations and less frequent magnesium, presented greater values on the
lagoons in the physiographys of "esteros and bajíos"
specially during the dry season. Concentrations of sulfur and iron rise
during the dry season, coinciding with reproductive season, this could
induce metabolic disorder related to mineral nutrition of the herds.
