Healthy soils provide the available nutrients for plants to grow. These are linked to the levels of organic matter, holding nutrients in the root zone ready to be taken up by the plant.

What to test:Important for:Main function
pHSoil pH and levels of acidity affect the availability of
plant nutrients.
Plants grown in acidic soils
experience stress and nutrient
deficiencies
NitrogenPlant cell division, vital for growth, amino acidsPhotosynthesis, production of
carbohydrates
PhosphorusPhotosynthesis, respiration and energy store, early
root formation
Important for root establishment
Helps plants survive harsh winters
PotashMetabolism and translocation of starches increases
carbohydrate and water efficiency
Important for shoot & leaf development.
Improves quality and disease resistance
MagnesiumKey to chlorophyll production, activates plant
enzymes
Influences earliness and uniform maturity
TracesPlant foods used in tiny amountsActivators of many plant functions

SOIL pH

Soil pH plays an important role in nutrient availability, a range of 6.5-7.0 is the best range for most crops.

HOW DOES SOIL PH AFFECT OVERALL PLANT NUTRIENTS

On farm testing

PH meters

Litmus paper

Garden kit

Commercial kits

Lab Testing

Standard Soil Analysis: Soil pH, Nitrate Nitrogen, Phosphorous, Potassium, Magnesium

Trace elements

Total & Plant available nutrients Base Saturation Test (proportion of elements in relation to soil parent material)
