Frequently asked

Answers for growers

What growers ask before they book on Agnomy.

  • What does a soil test measure?
    A standard agricultural soil test measures pH, salinity, and plant-available nutrients such as nitrogen, phosphorus, potassium, calcium, and magnesium, often with micronutrients and cation exchange capacity. Some panels add organic matter and trace or toxic elements. The results guide fertilizer and amendment rates for the crop.
  • Why is plant tissue testing useful?
    Plant tissue testing shows the nutrients actually inside the plant, which reveals deficiencies a soil test alone can miss. Labs report nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, and micronutrients like zinc, boron, and manganese. Sampling at key growth stages lets growers correct problems in season.
  • What does agricultural water testing check for?
    Irrigation water testing checks pH, electrical conductivity or salinity, and dissolved ions such as sodium, chloride, nitrate, calcium, magnesium, and bicarbonate. These affect emitter clogging, soil salinity, and crop health. Results guide filtration, acid injection, and amendment choices to protect both the system and the soil.
  • How often should farmers test their soil?
    Most growers test soil at least once a year or every one to two years, with high-value or intensively managed crops tested more often. Sampling at the same time each year makes results easier to compare. Regular testing tracks fertility trends and prevents both deficiency and costly over-application.
