How is Grower's Secret Nitrogen applied?

Grower's Secret Nitrogen is a dry, very hygroscopic powder which cannot be used dry or blended with dry fertilizers for direct application.  It is compatible with other fertilizers and can be used as a liquid pre plant or in season side-dress application. To optimize uptake and utilization by the crop GSI recommends dissolving the GSN in water and applying it as a foliar spray.  GSN may also be applied via drip or sprinkler irrigation.   

Will Grower’s Secret Nitrogen damage or burn my crops?

Grower's Secret 16-0-0 and 14-0-0 provides nitrogen in the form of protein hydrolysate. Protein hydrolysates are readily taken into the plant under warm and cool conditions and used for protein and chlorophyll synthesis.  There is no salt buildup and hence there is little chance of fertilizer burn.  GSI recommends you add GS Professional to your GSN applications to maximize nutrient uptake.  Why waste this valuable form of nitrogen?


What is the shelf life of Grower's Secret Nitrogen?

GSN is very hygroscopic and will absorb moisture from the air when packaging integrity is breached.  A sealed bag will last approximately 5 years form the date of purchase.  If moisture does enter the bag, the product will cake but will still be 100% usable.  It will however take longer mixing to dissolve the caked material.

What packaging sizes is Grower’s Secret Nitrogen sold in?

Grower's Secret Nitrogen is available in 50 lb. bags, and in 1,125 lb. super sacks.

Can Grower's Secret Nitrogen be used through a drip system?

Yes, through any form.

What is the proper application rate for Grower's Secret Nitrogen?

Naturally the amount of product to apply depends on the crop, it's stage of growth, plant health and yield potential. Always conduct crop and soil analysis to determine plant needs. In general, two to 10 pounds per acre, one to two times per month and at selected growth stages with influence yield and quality. GSI suggests starting with 2-5 pounds per acre with your initial applications and adjust the amounts as needed based on growing conditions, requirements, leaf N, and overall plant health. GSN is a perfect fertilizer to use when spoon feeding frequent low amounts of N to manage your crop.
