PRO●SOL’s water-soluble products have characteristics that set them apart from competitor’s products.
Only a limited number of materials can be used in the manufacture of a 100% soluble product, and only those materials are used in PRO●SOL.
To be completely homogeneous a product must be made from dry materials of uniform particle size. PRO●SOL is manufactured utilizing a unique production process which reduces all materials to a uniform particle size. This, along with thorough blending of the materials, assures a consistent product.
In laboratory and greenhouse tests, PRO●SOL out-performs competitor’s products with regard to consistent analysis and the absence of insoluble impurities.
PRO●SOL’s own manufacturing facilities give PRO●SOL flexibility to produce products that fit the exact analysis that a customer needs. With PRO●SOL, no one must conform to just a standard list of products.
Irrigation is a method of supplementing rainfall by artificial means. It is essential to maintain soil moisture during the growing season. Irrigation may be necessary to insure continuous plant growth. There are many types of irrigation, including trickle, drip, and micro-jet.
Stock solutions are typically made with a particular injector ratio or ppm (parts per million) parameter in mind. When making a stock solution, you must consider the area to be covered, the crop to be fertilized, the nutrients required, the accuracy of the injector, and total amount of water to be applied. Many greenhouse crops are highly susceptible to damage by certain types of nitrogen. Always refer to nitrogen breakdown on the label when deciding which product to use in irrigation.

Just as proper fertilization can greatly increase crop yields, fish pond fertilization can increase fish yields 2 to 4 times. In addition to increased yields, the fish will be in better condition. Infertile ponds seldom produce more than 100 pounds of fish per acre, while well-managed, fertile ponds can produce 300-400 pounds of fish per acre.
Fertilization of fish ponds stimulates algae growth. Algae are eaten by zooplankton and insects, which serve as a basic food source for bream and bass. Algae also make the water turn green, which helps shade the pond bottom. This helps prevent the growth of unwanted, bottom-rooted weeds and pond moss.
Full Stringer Benefits
Old fashioned types of fertilizer used for fish ponds were dry granular 18-46-0 and liquid concentrate 10-34-0. Auburn University research has shown that liquid fertilizers are superior to granular fertilizers in promoting rapid algae growth in fish ponds. Also, the cost of pond fertilization may be reduced, since smaller applications of liquid fertilizers can be used. However, these liquids are very labor- and time-intensive to apply, as they require diluting to 1/10 concentration and a slow rate of application to insure proper mixing in the pond water.
Full Stringer 10-52-4 offers the best of both worlds for fish pond management. Full Stringer requires no premixing or agitation because Full Stringer dissolves rapidly on contact with water. Application can be made by hand or aquatic applicator. One man can do in 1 to 2 hours what usually takes two men all day to do with other fertilizers. With Full Stringer Fish Pond Fertilizer, you fertilize the water, not the bottom of the pond.
Fish Pond Fertilization Management
Water clarity is a good way to determine when to fertilize. The depth that light can penetrate into the pond is a measure of the algae density. Light penetration can be measured using a Secchi disk, an 8-inch diameter disk quartered with the two opposite quarters white and black, respectively. Attach the disk to a yardstick or to a pole marked at 12, 18, and 24 inches from the disk.
Secchi Disk Reading
| Secchi Disk Reading |
Recommended Management |
| Greater than 24 inches |
Fertilize |
| 18 to 24 inches |
Good bloom – do nothing |
| 12 to 18 inches |
Dense bloom – watch closely |
| 12 inches or less |
Bloom too dense – determine source and be prepared to aerate at night |
| 6 inches or less |
Oxygen depletion imminent |
Full String Application Rates and Instructions
NOTE: Use a rate of 4 pounds of product per surface acre of water.
1. Make the first application of fertilizer in early spring when water temperature is consistently above 65ºF.
Follow with two additional applications at 2-3 week intervals.
2. Continue applications at 3-4 week intervals or whenever the water
clears enough that a white disk attached to a yardstick is visible to a depth of 18 inches.
3. Stop applications by the last week in September.
CAUTION: Over-fertilization of fish ponds can cause serious injury to stock. Do not fertilize ponds when the Secchi disk disappears between 12 and 18 inches – the bloom is too dense. If the disk disappears in less than 12 inches, the bloom is very dense, and a severe oxygen depletion could occur.
