Specialty Fertilizer

Iron chelated with EDDHA is a water soluble, dark red microgra-nular form of iron EDDHA to be used for the correction of iron deficiency in crops by means of soil application. 6% Iron EDDHA Chelate may be used at anytime, but spring applications before the flush or growth, or around planting time are particularly recommended in order to provide the iron at the time when the plants' needs are the greatest. Very effective even at high pH levels.

Dolomitic Limestone can be used to raise the pH (decrease acidity and increase alkalinity) of soil and soiless media by incorporating prior to planting.

Calcium nitrate (PureCal) is a fully water soluble fertilizer, that is a highly efficient sources of available calcium and nitrogen for plants under all growth conditions. It is a highly pure, white, fine crystal that is easily dissolved in water.
Suited for application through all fertigation and foliar application systems - drip systems, low volume sprinklers, center pivots and spray units.
As calcium is not mobile in the plant, it has to be continuously supplied throughout the growth season to keep adequate levels in the plant tissues and to ensure proper development. The nitrate nitrogen is readily absorbed by the plant and improves the efficiency of calcium uptake.

Sprint 138 6% fully chelated EDDHA iron chelate helps prevent iron chlorosis by maintaining and protecting iron availability in the most challenging soils that are alkaline or calcareous.

Sprint 330 and Sprint 138 are strong chelated forms of iron that maintain and protect iron availability. Sprint 138 is more effective when soil pH is higher than 6.5. Apply as soil drench at 3-5 oz./100 gal. (rinse excess off leaves & flowers immediately following drench.) For specific usage information including pictures please ask for a copy of the bulletin titled, "Iron Deficiency in Greenhouse Crops" by Paul Fisher, UNH and Rick Yates, Griffin Greenhouse Supplies.

Applied as a soil drench to drop soil pH and in the case of hydrangeas also provides the aluminum required for blue flower color.

MycoApply mycorrhizae are mixes of beneficial fungi which colonize the roots of plants and become a functional part of the roots. The increased effective root mass provides for more efficient water and nutrient uptake, increasing the ability of the plant to withstand stresses and establish more quickly. Ninety-five percent of plants form these symbiotic relationships with soil mycorrhizae in nature. The majority utilize the Endo(interior) mycorrhizae, but many types of trees utilize the Ecto(exterior) forms. The colonization and benefits last the lifetime of the plant. MycoApply is supplied as a granular formulation for field and soil incorporation, a suspendable powder for soil incorporation or drench application, or as the Soluble Maxx formulation.
