Horticulture soils are tested to measure the soil quality and nutrient levels for monitoring fertiliser programmes and to assist with identifying nutrient deficiency or toxicity.
About this Testing
Soil testing takes the guess work out of nutrient management and allows cost effective fertiliser programmes to be produced, targeting fertiliser applications where they are most required to meet the grower’s objectives.
As an independent laboratory, we leave the fertiliser recommendations to competent advisor's who know the property and the grower’s objectives.
The soil tests to order
For Horticultural soils a Basic Soil Profile, sulphate-S and available nitrogen (AN) test are usually recommended.
For Avocado Orchards a Basic Soil and Mehlich 3 trace nutrients test is recommended.
For Kiwifruit Orchards a Basic Soil Profile and available nitrogen (AN) test is recommended.
For Vegetables a Basic Soil Profile, sulphate-S and available nitrogen test is usually recommended.
Other soil tests include organic sulphur, aluminium, boron, EDTA trace nutrients and more. Where reactive phosphate rock (RPR) fertilisers have been used, the Resin P (RP) test is recommended to measure plant available phosphorus.
The Organic Soil Profile measures the soil quality and includes total nitrogen, available nitrogen, organic matter (total carbon) and the soil total carbon:total nitrogen (C:N) ratio.
