Why Fertigation?

Water dispersible fertilizers greenhouse fertigation, hydroponics, foliar feeding, planting of field crops, and turf

Fertigation provides more precise control of plant-feeding. There are many systems and approaches for growing plants, and each has its benefits. Wherever water is provided through irrigation, additional nutrients can also be delivered. By precisely dosing plants with only the nutrients they need as they grow, there is reduced potential for nutrient loss in the growing system. That can mean better control of plant growth, greater nutrient use efficiency, and less waste.

Commercial nurseries and greenhouses grow plants with diverse nutritional needs. While a typical soil or constructed potting mixes can provide all of the nutrients a plant needs to grow, supplementing those matrices with different concentrations of key nutrients, particularly nitrogen, can improve the rate and quality of plant growth.

Turfgrass managers and landscapers sometimes need quick greening. In the green industries, people who produce and manage turfgrass know that color and thickness are key qualities demanded by many customers. Balanced nutrition also helps keep grass healthy and more tolerant of foot traffic and other environmental stresses.

Fertigation Rates and Application:

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. of Suståne 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. powder per gallon of water (or 60 g per liter). 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 the working solution within 4 hours of preparation. Rinse sprayer thoroughly with water immediately following application to avoid clogging.

For Turf

For turf applications, use 0.9 lb. of Suståne Hi-N WDF per 1,000 ft2 using 2 gallons of water (500 g per 100 square meters using 7.8 liters of water). To do so, mix in 0.45 lb. Suståne Hi-N WDF per gallon of water while filling the applicators reservoir tank. With constant agitation, apply 2 gallons of working solution per 1,000 ft2 (7.5 liters per 100 square meters) of turf to provide 0.1 lb. of N per 1,000 ft2. Apply the working solution within 4 hours of preparation. Rinse sprayer thoroughly with water immediately following application to avoid clogging.

Application rates and use instructions:

Application rates of Suståne water-dispersible fertilizers should be made based according to a crop’s nutritional needs and tolerance for salt stress. 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. The preparation of a homogenous solution is critical to successful and consistent 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 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 the reservoir.

Make sure the intake end is not touching the bottom of the reservoir and allow the 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 85oF (30oC). 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.
