COVID-19 Update 

Ravensdown and ARL have been deemed as essential service meaning we will continue to offer some services.  We will continue to support our customers and our field-based teams, however we will be limited in the volume we can process.  

This service will include water, apple mineral, dry matter, and limited feed quality testing.  We will endeavor to keep to our turnaround times the same for the reporting of essential water and dry matter results. To ensure this happens within our limited capacity, we ask for you to please drop samples off before 10am, dropping off samples prior to 10am ensures we have someone available to support you with your sample submission.

Feed quality, plant tissue mineral and soil mineral analysis will only be analysed when our reduced team have capacity. Where possible, we ask you to hold off submitting non-essential samples until after the shutdown period.

We have also put processes in place in accordance with the Ministry of Health Guidelines for sample drop-off with the intention of keeping both your teams and our teams safe. The front door is now locked with a bell to ring when you arrive and a drop-off station created in the foyer. To limit contact even further, please come with a completed submission form and drop it and your samples on the trolley provided.

Why test with ARL?

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.
