Unique characteristics of GRIGG BROTHERS products, which are responsible for their superior performance, are as follows:

• All products contain a series of selected natural organic compounds, "Organic-facilitators," which chelate or complex nutrients and keep them in functional form until the plant utilizes them. These natural compounds are plant and micro- organism based.
• These complexing and chelating agents hold the nutrients in their proper ionic and functional form against pH differences encountered in the tissues of the plant organelles and protect them from tie up within the plant or precipitation by sulfates, silicates and phosphates.
  

GRIGG BROTHERS nutrients in the proper ionic form are optimal for plant utilization.

GRIGG BROTHERS natural organic compounds "organic facilitators," assist in the vascular transport of all nutrients to the plant cells and keep the nutrients mobile and available to the plant cells.

GRIGG BROTHERS chelates and/or complexes are naturally occurring plant based compounds and therefore biodegradable by plant cell enzymes. There is no accumulation of residues in the plant or in the soil as with synthetic chelates such as EDTA or HEDTA.

GRIGG BROTHERS natural chelates have high binding or stability constants which permit micro nutrients such as iron, copper, and calcium to be mixed with macro-nutrients (N, P, K,) plus magnesium and sulphur.

GRIGG BROTHERS products have a specific nitrogenous base which enhances absorption though the thick, waxy cuticle of a leaf surface. Other nitrogenous compounds such as nitrates, and ammonium ions are less effective.

GRIGG BROTHERS products may be applied to the soil or in irrigation water in addition to foliar application. The natural compounds contained in them enhance soil bacteria activity, resulting in improved soil conditions, however they are most effective when foliar is applied to the plants.

Foliar Application of nutrients is the most economical and effective way, providing that the nutrients are in a plant usable form as are GRIGG BROTHERS products. Foliar applications of nutrients in the usable form eliminate the problem of soil fixation, or tie up of micro or macro nutrients, provided they are properly chelated.

Using Full Laboratory Support for soil and tissue analysis will help ensure that GRIGG BROTHERS products will fit your turf's nutritional needs.
