Soil Nutrition Analysis

Surface Soil Sampling

Our comprehensive surface soil analysis testing provides a full spectrum analysis not only of the important macronutrients such as nitrogen, phosphorus, potassium, sulphur, calcium and magnesium but also includes critical information on important micronutrients such as zinc, manganese, iron, and copper. Monitoring of these micronutrients is critical in maximising yield potential.

Deep Soil Sampling

IK Caldwell has invested in equipment that allows for efficient sampling of soil down to 1 meter. Typically, for a deep nitrogen analysis we sample down to 60cm randomly across the crop. Analysis results are then entered into a nitrogen budgeting tool that estimates nitrogen demand of the plant and nitrogen supply in the soil. This enables IKC agronomists and growers to make more informed nitrogen top dressing decisions.

Remember that testing over time, combined with testing across many sites can provide a broad picture of key areas where nutritional inputs are required or where imbalances need to be managed. Soil analysis can be used to diagnose nutritional imbalances in areas where it is obvious that plant growth is restricted and can target these imbalances before costly visual symptoms emerge.

IKC only use NATA or ASPAC accredited soil laboratories
