The economics of Agricultural Analysis
We believe that “careful use of science and technology applied to farming can increase yields” with a greater profit to you - the farmer.  A small investment in a soil or plant tissue test can save you money with better use of the fertiliser dollar.

As agriculture becomes more scientific every day, the opportunity exists for farmers to better utilise their current resources.  The only way this can be achieved is to increase your knowledge of what your farm can offer you. 

This means being aware of the nature of your soil, understanding the needs of the plant species you plan to grow, and monitoring an effective planned fertiliser programme for either pasture improvement or higher crop yields.

Interpretations and Recommendations

Our laboratory services will identify nutritional problems in crops and soils and will help you to refine your farm management decisions.  Laboratory results require interpretation.  That is why our staff specialise in agricultural science, so as to offer you comments about your results.  We recommend the appropriate nutrient regime for your crop or pasture and can identify nutrient deficiencies and/or toxicities.

Sampling Techniques
The most important aspect in any testing programme is the field sampling procedure.  The difficulty of obtaining representative samples has often been a major reason why testing is sometimes held in question.  Research has shown that the number of sub-samples in the sample is highly significant in improving the reliability in the sample.  When the number of sub-samples per sample is increased, the reliability of the samples increases dramatically.
