Plant sap analysis shows plant mineral levels and highlights nutritional deficiencies and excesses before they cause any damage. Sap analysis provides the opportunity to determine the precise amount of a needed nutrient before a deficiency manifests as a disease or weakness.


Leaf analysis, also known as stem leaf analysis, tissue analysis or foliar analysis, is the most accurate method of monitoring plant nutrient levels. Leaf analysis shows the farmer exactly what the plant has successfully absorbed from the soil and this allows specialists here at Precision Nutrition to advise on what minerals are needed to help crops achieve optimum yield potential.


Plant SAP or Leaf analysis will:

• Show the nutrients taken up by a plant
• Is a tool to help you adjust your nutrition management plan accurately and quickly
• Help improve natural disease resistance
• Reveals any nutrient deficiency in an early stage and give you time to take action
