For Certified, Organic Production

Suståne Hi-N 12-0-1 Water Dispersible Fertilizer (WDF)

Application rates of Suståne water dispersible fertilizers should be made based according to a crop’s nutritional needs and tolerance for salt stress (see reverse). WDF should be diluted in water and mixed well prior to application. For best results, add package contents to fresh water in clean containers with mixing as described below.

Preparation of a homogenous solution is critical to successful fertigation. It is highly recommended that growers prepare a base concentrate of Suståne’s WDF in a bucket of water and then mix the concentrated solution into a larger volume of reservoir water to ensure proper mixing prior to dispensing.
Prepare a concentrate of 0.5 lb. of powder per gallon of water (60 g per liter) in your reservoir. Add the powder slowly while stirring until the required amount has gone into solution. Use a pre-filter screen on the reservoir's injector line. After the concentrate is fully mixed, let the solution sit for 15 minutes before placing the injector hose into reservoir.

Make sure the intake end is not touching the bottom of the reservoir and allow injector to pump all but 2% of the concentrate volume to avoid uptake of any contaminating grit that might rapidly clog intake screens. After fertigation, the remaining concentrate may be fully diluted and injected directly as part of the initial flush.

Apply fertigation solutions ONLY when temperatures are above 50oF (11oC) and below 85o F (30o C). Commercial users should check the pH and EC of the prepared fertigation solutions to make sure they are within acceptable ranges for their specific crops.

When diluted correctly, this product can be applied to plants through high volume, wide bore sprayers and piped irrigation lines. Pre-filtering is required to prevent clogging of narrow gauge lines and emitters. To minimize risks of clogging and biofouling, install lines with the widest bore that is practical and use the highest flow rates that work with that irrigation system. Be sure to flush all lines with water after each fertigation and fully clean lines on a monthly basis.

FOR Hydroponics & Greenhouse Fertigation

Use up to 2 lb. (0.9 kg) of 12-0-1 WDF per 100 gallons of water for finished solutions with up to 300 PPM of N. To do so, prepare a base concentrate by thoroughly mixing 0.5 lb. (60 g per liter) powder per gallon of water. This base concentrate can then be diluted into 50 to 150 volumes of water to obtain working solutions of various strengths. Working solutions can be applied regularly depending on crop demand and growing conditions.

For Field Crop Starter Fertilizer
For in furrow and side dress drench applications, apply up to 40 lb. of Suståne Hi-N WDF per acre in no less than 200 gallons (45 kg per hectare in no less than 780 liters of water) of solution. To do so, mix up to 0.2 lb. of powder with each gallon (or 25 g per liter) of water while filling the mixing tank. Ensure powder is fully dissolved before application. Apply within 4 hours of preparation. Rinse applicator tank and pump lines thoroughly with water immediately following application to avoid clogging.

For Foliar Feeding
For foliar applications to fruiting crops, apply up to 3 lb. of Suståne Hi-N WDF per acre using 100 gallons of water (3.5 kg per hectare using 1000 liters of water). To do so, prepare a base concentrate by thoroughly mixing 0.3 lb. of Suståne Hi-N WDF per gallon of water (36 g per liter). This base concentrate is then diluted 1:10 with water in the spray tank to prepare the working solution for foliar feeding. Apply 100 gallons per acre (or 1,000 liters per hectare) one to four times per season. Apply working solution within 4 hours of preparation. Rinse sprayer thoroughly with water immediately following application to avoid clogging.

Available in 5-gallon pails.
