To have successful pond production, ponds must be properly sited and built, with careful assessment of water availability, quantity, and quality. Hay should be applied at the rate of three to ten bales, or 200 to 500 pounds, per surface acre. The quantity of phytoplankton produced must be closely monitored for a successful fertilization program. Ponds differ in the amount of fertilizer needed to produce the desired response. After it clears, the pond may need an additional bag or two per year to keep it clear. These organisms includephytoplankton*, zooplankton* and insects (see Chapter 10, ). The first indication of upcoming oxygen problems is the water turning a brown color. Fertilization can cause a pond to turn green and may reduce its aesthetic value. Inorganic fertilizers act through the primary production of the pond while organic manures can, in addition, directly stimulate higher trophic levels supplying organic matters and detritus. Fertilization and liming can improve pond production for fishing. At 10- to 14-day intervals add more hay until the pond is clear, but use only four applications per year at most. Amy Myers: Should all of our listeners be fertilizing their ponds? The results of research have led to many different recommendations on the nutrients that should be contained in a fertilizer, the amounts of each nutrient to add per application, frequency of application, etc. Fertilization can increase fish production by three to four times, resulting in more fish, bigger fish or both in properly managed ponds. Once a program is started, it needs General instructions to fertilize. Below are the physical and chemical requirements that should be met prior to initiating a fertilization program. The right fertilizer is a fertilizer high in phosphorous and low in the other 2 elements. Pond fertilization is an art, and pond managers must ultimately try different fertilization regimes until a satisfactory one is found. Wes Neal.

Fertilizing specifics - Pond fertilization should be done at two-week intervals. POND FERTILIZATION Applying the proper pond fertilizer to a lake has the same effect as fertilizing your garden, your lawn or your agricultural crops; it increases your production. Scatter it evenly across the pond’s surface. Rooted vegetation should not cover more than 20 percent of the surface area. Creation of a bloom in a pond never before fertilized can take months. Ending a fertilization program will leave a pond with more fish biomass than it can support, resulting in stunted, skinny fish or a fish kill. Water visibility, determined by taking a Secchi disk reading, should be greater than 20 inches. A fertilization program can greatly increase fish production in fishing ponds. A properly managed fertilization program should increase both numbers and average size of fish caught. The rate should be adjusted accordingly to the phytoplankton response. In this case, you can grow more fish in a pond via fertilization. A fish pond, or fishpond, is a controlled pond, artificial lake, or reservoir that is stocked with fish and is used in aquaculture for fish farming, or is used for recreational fishing or for ornamental purposes. If a fish species which consumes small natural foods is grown, such as the bluegill or golden shiner, then pond fertilization can increase the production of these fish. Vegetation must be reduced to this desired level prior to fertilization because the added nutrients will promote the growth of the vegetation rather than phytoplankton. One can also increase the productivity of a pond by adding fertilizer. In addition to being cheaper, hay offers the beneficial side effect of adding organic fertilizer. If the pond is muddy, steps to remedy the causes of turbidity must be taken before fertilization. A properly managed fertilization program should increase both numbers and average size of fish caught. There seems to be no confusion about rivers, seas, and oceans, but two water bodies that are very similar to each other and make it difficult for people to name … Pond fertilization is important to increase primary productivity in extensive culture ponds and enhance the base of the food web for aquaculture animals. Consider the long-term use of ponds before starting a fertilization program. This problem is made more acute if an unusual number of cloudy, windless days occur in the summer. Fertilization will produce algae bloom, or phytoplankton in your pond. Water occurs on the surface of the earth in the shape of many types of water bodies such as oceans, seas, rivers, creeks, lakes, ponds, and many more. Both chemical and organic fertilizers act by directly stimulating phytoplankton production within the pond. Fertilization can increase fish poundage by as much as three fold in some ponds. If this occurs, decomposition or respiration of the phytoplankton at night can consume all of the available oxygen in the water and cause fish kills. This disk is lowered into the unshaded water and the depth at which the disk is no longer visible to the naked eye is called the Secchi disk reading. As water temperature increases, feed input ... Pond Fertilization BMP No. Proper fertilization is a critical component to successful pond management. Nutrients provided by the addition of fertilizer increases the quantity of phytoplankton (microscopic plants) which form the base of the food pyramid in all aquatic systems. Application of liquid fertilizer can be made with a commercial sprayer in large ponds or a small garden sprayer in smaller ponds. Definition In the early spring, catfish ponds may have clear water. First, establish good plant cover in the watershed and along the shoreline to reduce the amount of muddy runoff into the pond. In the medieval European era it was typical for monasteries and castles (small, partly self-sufficient communities) to have a fish pond. If the Secchi disk reading is 20 inches or less, discontinue fertilization until the reading exceeds 25 inches. The granular blend can be changed to a 0:46:0 formulation and applied at the rate of four pounds per acre. Secchi disk readings should be made at no less than weekly intervals. Apply compost to fish ponds at rate of 20 to 25 kg/100 m2 of pond surface area every ten days as a rule-of-thumb. crop irrigation and fish pond fertilization, as well as when weak sewage is to be treated prior to its discharge to surface waters.
