    abstract = {The purpose of this research was to determined if the 227 
  ha used in the cultivated soils of the five different stables destined for the 
  production of milk and specimens of the Holstein Friestan stock found in Guadiana 
  valley in Durango are affected by the well waters used in irrigation and the 
  residual waters of the automatic milking process. The variables of the study 
  included: apparent density (Da), total Nitrogen (N), Phosphorus (P), potassium 
  (K), sodium (Na), Calcium (Ca) and Magnesium (Mg). The experimental period consisted 
  of 3 consecutive days in each of the production units using the method of cutting 
  for the recollection of the samples consisting of soil, for its future analysis 
  in a lab. The obtained results were processed through the program of statistics 
  (SAS) Version 8 with a module completely at random. Analyzing the results between 
  each stable the variable measurements can be observed in the tables from 1 through 
  5. The variables found in the comparison between the five production units were: 
  density, the stable with the highest amount was stable 2 and the stable with 
  the least was the stable 1 with a difference between the stables of high significance; 
  recorded in the table provided (p<0.05). Nitrogen was another element present 
  in the stables with the highest number was the first stable and the one with 
  the lowest was the third stable with a difference between stables of p<0.05. 
  Phosphorous appeared in the stables with the highest measurements found in the 
  fourth stable and the slightest was the first stable with a difference between 
  stables of highly significant readings (p<0.05). Sodium in the stables appeared 
  with the highest number in the first stable and the tiny amount in the third 
  stable with a difference that was significant (p<0.05). In the meantime, 
  the correlation showed the following results: the highest correlation (0.95715) 
  appeared between the magnesium and the calcium which results in a significant 
  number (p<0.01). A significant correlation (p<0.05) between the variales 
  of total nitrogen and potassium with a value of 0.58496 appear in the findings.}
