GREENHOUSE ANALYSIS

SGS offers a full range of analytical services to greenhouse growers. Suggested sampling frequencies for each are outlined below:
  • Source Water -  Test before each production season, especially water sourced from ponds and wells which may have differing mineral content from year to year.
  • Solution - Weekly to monthly testing allows monitoring and adjustment of nutrient levels, pH, and EC.
  • Growing Media - Test once before planting, and once mid-season, to determine the nutrient content, pH, and EC of the media.
  • Plant Tissue - Weekly or monthly nutrient analysis allows monitoring of the adequacy of fertilizer programs, and diagnosis of deficiencies and toxicities before plants become visually symptomatic.
  • DNA Multiscan - Monthly or seasonal monitoring of plant pathogen levels allows control before diseases develop in the crop. Large Scan for diagnosis is utilized to determine which pathogen and subspecies is in high levels and likely to be causing the visual symptoms.
  • Plant Diagnostics - As the DNA multiscan measures only fungal oomycetes, viral infections such as Pepino or Cucumber Mosaic can be diagnosed or confirmed by other methods. 
MIXER VALIDATION

The quality of a mixed feed is, in part, the result of the uniform distribution of ingredients throughout.  The determination of mixer performance is therefore an important step in high quality complete feed production.  SGS offers mixer validation testing for common nutrients including manganese, zinc, sodium, and salt.  A minimum of 10 samples must be provided.
