PRODUCT DESCRIPTION:
SRN 28-0-0 Liquid Fertilizer is well known safe ,reliable ,slow release nitrogen solution ideal for turf and tree applications. With the lowest salt index of any nitrogen source it is safe (non-phytotoxic) and very economical to use . SRN 28-0-0 is formulated with 58% methylene urea nitrogen that provides weeks of steady nutrition for all type of turf grass including cool , warm and transitional grasses. This exclusive proprietary formula is composed of a nitrogen / carbon molecule that is also an energy source for beneficial soil microorganisms . This crystal clear solution , contains 58% slow release nitrogen along with small percentages of free urea. SRN 28-0-0 provides residual nitrogen release , low volatilization and reduced leaching . The release of nitrogen depends on soil microorganisms, hydrolysis and UV radiation. It works in conjunction with the increase in soil temperature, microbial activity and the plant’s increased need for nitrogen. This form of nitrogen molecule resists leaching and volatilization, making it a cost effective nitrogen source. It is ideal for fertigation systems and is non-clogging and non-abrasive. SRN 28-0-0 can be safely tank mixed with many acidic and alkaline materials. It has natural sticker / spreader properties.
SUGGESTED USES:
SRN 28-0-0 Liquid Fertilizer solution is a safe, non-burning, reliable nitrogen source for all turf grass applications (including cool, warm and transitional grasses), tree and ornamental applications. It can be used along with other technical products for low volume foliar spraying or soil root injection. SRN 28-0-0 will enhance contact herbicides and insecticides. It is ideal for fertigation system since it will not clog or cause abrasion.
APPLICATION RECOMMENDATIONS:
Turf Applications: SRN 28-0-0 can be applied throughout the growing season on cool, warm and transitional grasses. Dilute with water according to desired nitrogen rate per 1,000 sq. ft. See Tank Mixing Chart for exact quantities for various rates of nitrogen and different volume spraying . Yearly nitrogen application rates can be reduces by 1/3 as compared to granular applications.
Turf Grass / Lawn Care: SRN 28-0-0 liquid nitrogen provides residual nitrogen release to assure consistent green color between spray applications on all turf grasses including Bentgrass, Rye, Fescue and warm season grass. SRN 28-0-0 can be safety used on Rye overseeded areas. It is ideal for both foliar spray on trees and shrubs and is compatiable with herbicides, fungicides and insecticides. No special agitation is needed.
Tees, Greens & Fairways: SRN 28-0-0 is recommended for all type of grasses, including Kentucky Blue, Bent, Fescue, Perennial Rye, Bermuda, St. Augustine and Bahia. Nitrogen application varies according to climate and grass variety, so be sure to check the appropriate amount of nitrogen to apply per season, as each grass variety will be different. SRN 28-0-0 is compatible with most other turf insecticides and fungicides.
Trees & Ornamentals: The nitrogen release period for deep root injection extends 3 to 6 months depending on soil and climate conditions. There is no danger of phytotoxicity. No special agitation is required. For trees, apply 1lb. Nitrogen per 1,000 sa. ft.(under canopy). Inject 4”-8” below soil surface, into root zone, with correctly calibrated tree fertilizer injection equipment. For ornamentals, apply 3/4 lb. Nitrogen twice a year as a soil drench.
Greenhouse & Nursery: SRN 28-0-0 is ideal for both supplement feeding and constant feed of nursery stock for both foliar and root uptake. This clear liquid can be injected through fertigation, drip irrigation or overhead sprinkler systems.
STORAGE & HANDLING:
Can be stored in temperatures below 32℉/0℃. Freezing temperatures may cause SRN 28-0-0 to become viscous. If frozen, place in warmer temperatures and mix with warm water, SRN 28-0-0 will regain its normal fluid state. Freezing does not affect the agronomic quality of this product. It is not corrosive to most metals with a slightly alkaline pH and can be used through any irrigation or spray equipment.
Bulk Storage: SRN 28-0-0 can be stored in polypropylene, fiberglass, stainless or mild steel tanks. Heat does not affect this product. Recommended storage temperature for SRN 28-0-0 is 32℉/0℃ and above. When stored outside for long periods of time in temperatures <32℉/0℃ it is recommended to dilute the concentrate with water by 10% to assure fluidity.
Dilution: SRN 28-0-0 can diluted by either adding the concentrate to water or the water to concentrate without any detrimental effects on the final mixed products. Appropriate quantities of water should be added prior to adding potassium and phosphates or pesticides, fungicides and herbicides.
Mixing: SRN 28-0-0 must first be diluted with water prior to mixing with other nutrients or pesticides. Do not mix concentrated technical materials together without first diluting with water. Care should be taken when blending SRN 28-0-0 with highly acidic materials such as phosphoric acid or ammonium sulfate. Neutralize these materials to a pH of 7 or above. Potassium phosphate, potassium chloride, potassium nitrate, urea and urea ammonium nitrate or phosphorus solutions may be readily blended with SRN 28-0-0 after dilution with water.
The following mixing procedures should be used after SRN 28-0-0 has been diluted with water. Add products to mix in this order: 1. wettable powders, 2. flowables, 3. Water solubles, 4. surfactants, 5. emulsifiable concentrates. Be sure to agitate during each addition. Mixed well before adding next and apply all of mixture that day. SRN 28-0-0 can be mixed with copper based fungicides.
