Green Crop Nutrition knows farming & horticultural products with over 50 years of experience in the green industry. Our company is your source for the finest natural, sustainable products that maximize results for conventional or organic growing practices. Our staff has experienced, trained specialists who are ready to serve you. Our unique products include:

AZOMITE® - a natural volcanic pumice product that completely mineralizes your soil.  AZOMITE® is an incredible bio-available fertilizer supplement that supplies over 70 major, secondary, and trace minerals. AZOMITE® has a high level of bio-available silicon (as silicon dioxide unlike sand which is unavailable silicon oxide) and good levels of potassium, calcium, and magnesium. Azomite eliminates "hidden plant hunger".

Premium-blend Compost - has over a dozen natural minerals blended in, takes seven years to make the base compost, is composted again for another year, and is a compost that "grows like no other".  Our own specially formulated Premium-blend Compost provides you a perfect "instant plant food and growing medium" that keeps on releasing for more than a year. Just a light top-dressing once per year maintains an ideal growing medium. 

Olive trees (fruiting varieties) - A great selection of varieties for commercial production, home, or landscape. Varieties available include Arbequina, Chemlali, Coratina, Koroneiki, and Picual.

Agri-Fos - a systemic phosphite fungicide (phosphorous acid with potassium)  for highly effective, systemic control of various plant diseases.

Liquid Potassium Silicate (Stimp-up) -  a great plant nutrient that works as a fungicide and insecticide - improves over-all plant quality and hardiness. 

Super Hume with Seaweed - Humic Acid with high fulvic acid blended with liquified kelp - great for enhancing mineral uptake and providing trace minerals in an organic formulation that the plant can instantly absorb and readily translocate throughout the plant. Improves plant metabolism and helps prevent xylem and phloem blockage caused by disease bacterium and hard to translocate forms of trace minerals. Helps improve plant health, yield, quality, and cold hardiness.
FloraBoost - boosts the effectiveness of foliar programs with researched bio-available metabolites to promote a greater number of strong, healthy, disease-resistant blooms that set more fruit. FloraBoost has a 5-0-16 analysis, contains organics, and 21 L-amino acids,  energized fulvic acid, humic acid, organics, salicyclic acid, and a super-penetrating botanical surfactant.
FloraBoost for Citrus: Works especially well when used to complement our proprietary foliar Citra Thrive Plus in a Citrus spray program,.
FloraBoost for Olives: Works to promote bloom and fruit set in olives when sprayed three times per year at the rate of 2 gallons per 100 gallons of water (2 ounces per gallon) early in the year before spring flush, May or June, and September or October.
FloraBoost promotes bloom in all types of flowering plants and more flowers and fruit in all types of fruiting plants.

Our organic compost without additional additives grew this 
incredible broccoli in 2 months from a small bedding plant
 AZOMITE® mineralizes soil and grows incredible crops, beautiful turf, pastures, and greens. It also is a great livestock feed supplement.
Just a short distance from the Atlantic Ocean in Port Orange Florida, this grove of Arbequina olives is just 18 months old (Fall, 2010). The olive trees were 18 inches tall when planted - they now stand over 8 feet tall with olives already on the trees.
