Analytical Research Laboratories Limited is a wholly owned subsidiary of Ravensdown and offers complete analytical services. ARL is New Zealand's leading soil, plant, feed, water and fertiliser analytical laboratory.
ARL is an IANZ (International Accreditation New Zealand) accredited laboratory (ISO 17025) and a member of the New Zealand Association of Consulting Laboratories and ASPAC (Australasian Soil and Plant Analytical Council).
We offer an extensive range of soil, plant, feed quality, water and effluent analysis suites.
These testing services provide information essential to measuring and managing the health and productivity of your soil, crops and animals.
Soil testing establishes the nutrient status (the reservoir) of the soil. It is the first step in designing a fertiliser programme. It does not, however, indicate whether plants grown in the soil are capturing all of the nutrients available, or if the nutrients they need are in the correct proportions.
Plant analysis, on the other hand, indicates whether the plant has the right amount and balance of nutrients for optimal production. This is a very useful tool in assessing trace element status for animal health, pastoral herbage, and in arable and horticultural crops.
Soil testing and plant analysis are best used in conjunction with each other to give you the best picture of your block and crop to aid in management decisions.
