Roots, Shoots & Fruits are proud to provide the upmost of service to you our clients and the Balanced Analysis service is no small part,  assisting with nutritional recommendations based on leaf analysis samples from your local laboratory –Hill LaboratoriesARL Laboratories etc.

Please email your analysis or have your laboratory email analysis results to to utilise this Balanced Analysis service.


Our company uses a unique analysis and interpretation method which takes into consideration the interaction of all plant minerals, and provides the grower with precise knowledge of the crop situation, allowing us to formulate a well balanced nutritional program which can be readily utilised.

JH. Biotech, Inc. of  Ventura California,  has developed a unique and comprehensive way of interpreting leaf analysis data. The system is called (BA) or Balanced Analysis. It is based on the fact that minerals interact with one another, and that a comprehensive approach looking at all minerals together is the best way to properly assess deficiencies.



Speaking of balanced figures and deficiencies, we must not forget excesses, as they can inhibit other minerals.

The traditional method of interpretation, which allocates an acceptable range for each mineral, has many faults and restrictions:

  • It disregards interactions of elements
  • It can not predict ideal levels for individual cases
  • It can not recommend exact application rates to treat problems
  • Analysis is restricted to a particular plant part and to samples taken at certain periods of growth.
  • Its ideal individual figures (critical levels) are restricted to certain geographical areas as they are based on historical data
  • Invariably, it reports no deficiencies when in fact deficiency symptoms are visual.
  • They are handicapped by the fact that not all critical levels for all minerals are established for all crops in all areas

These restrictions make traditional leaf analysis reports of reduced practicality.

Via the J.H Biotech Balance Analysis, all mineral levels are regarded simultaneously as parts of one integral unit. After the analysis is done, the data is fed into a database. The output produced lists the minerals in order from the most deficient (at top), to the least deficient (down the bottom). A Nutrient Index is also assigned, describing the level of minerals. Negative levels indicate deficiencies. The more negative the number, the higher the deficiency, and vice versa. The most deficient element is that which is most yield and/or quality limiting. Our team will then write an integrated nutritional program/ recommendation specific to your crop, from the results obtained via the analysis.

Somewhere in the Nutrient Index, there may be an element with a value of zero. This mineral is regarded as having ideal levels for the given crop, stage of growth and in relation to all other minerals. Ideally, if all Nutrient Index levels are zero, then the levels are considered in balance.

The actual Analysed Result is then compared to the Reference Level. The recommendation given is intended to bring the levels of all the elements in balance with each other, for optimum quality and yields.

The Balanced Analysis is crop specific, and regards mineral ratios rather than absolute levels. The wealth of information fed into the computer in developing the software enables the prediction formula to not be restricted by any stage of growth, location, or plant part; as long as it is a fully mature viable leaf.

Last but not least, the recommendation is usually for foliar feeding. Soil adjustments (especially when soil analyses are undertaken) are also recommended. We do not apologise for recommending the JH Biotech foliar products because we believe that no other product will provide the deficient mineral in a more available and efficient form than these modern technologies.
