Nutrient Mapping

SOYL provides GPS sampling, analysis and mapping to provide you with detailed soil nutrient information to make informed management decisions. By accurately identifying variations in phosphorus, potassium, magnesium and pH levels you can:

> Reduce fertiliser and/or lime expenditure

> Improve yield where nutrients or acidity are limiting factors

> Provide a nutrient management plan to justify fertiliser usage

> Reduce environmental impact by eliminating application to areas with high nutrient status.

How does it work?

A SOYL trained sampler will sample your fields using GPS. SOYL use strategic sampling and take a minimum of one sample per hectare. These soil samples are independently analysed for phosphorus, potassium, magnesium and pH. Based on the results SOYL creates maps for each field showing nutrient variation across the field.

Your FACTS qualified SOYL contact will help you to understand and evaluate the nutrient maps to proceed in the most efficient way for your business. SOYL provides fertiliser recommendations based on your cropping, soil type, straw removal decisions and target yields. We can then provide variable rate spreading files for your GPS system.
