Roots Shoots & Fruits are proud to provide the upmost in service to our clients.

We can assist you with balanced nutritional recommendations based on leaf analysis samples from your local laboratory.

Please email the analysis or have your laboratory email analysis results along with a completed grower sheet to utilize this service. For step by step guidance through this process please open the 'guide to utilize  Balanced Analysis Service' in the maroon section.

Because of the extremely complex interactions which take place between elements, JH Biotech have patented a system whereby interaction of elements can be measured and taken into account.

Complex Nutrient Interactions


Below is a diagrammatic representation of nutrient interactions. It represents the complexity of plant nutrition and the need to regularly monitor soil and leaf levels throughout the growing season.



For example, excess Calcium will affect the levels and uptake of Zinc, Phosphorous, Magnesium and Manganese. This is symbolized by the direction of the arrow heads. The double arrow heads represent the interaction can go both ways between the elements in concern.

Our company uses a unique computerized interpretation method which takes into consideration the above interaction wheel, and provides the grower with precise knowledge of the crop situation, allowing us to formulate a well balanced nutritional program which can be readily utilized by the crop in question.







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. As the name indicates, it is based on the fact that minerals do interfere with one another, and that a comprehensive approach that can look at all different minerals is the only way of properly assessing 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 totally overlooks interactions of elements
It can not predict ideal levels for individual cases
It can not recommend exact application rates to treat problems
It is restricted to a certain plant part and to a certain period of growth.
Its ideal individual figures (critical levels) are restricted also to certain geographical areas.
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.

All of these restrictions make traditional leaf analysis reports of very little practical value.

With the Balance Analysis of J.H Biotech, all mineral levels are regarded simultaneously as parts of one integral unit. After the analysis is done, the data is fed into the database of the computer. The computer will then list the minerals in order from the most deficient (at top), to the least deficient (down the bottom). The computer will then assign a Nutrient Index that describes 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. Therefore, the team will write an integrated nutritional program/ recommendation pertinent to that crop and the results obtained from the analysis.

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

The computer will then compare the actual Analyzed Result to the Reference Level. The recommendation given is intended to bring the levels of all the elements in balance with each other as they should be for optimal quality and yields.

The computer program employed 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 appologize 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  highly available technologies
