Thus, in aquaculture, there is no particular advantage of ammonium polyphosphate over granular phosphate fertilizers. The polymerized phosphate hydrolyzes in water to regular orthophosphate. Inorganic fertilizers are chemical fertilizers that contain nutrient elements for the growth of crops made by chemical means. It also can be classified according to its ingredients, whether it is solid or liquid and by its particular actions, s… The type of system used for aquaculture production is a combination of the above . Liquid ammonium polyphosphate has a density of around 1.4 grams per cubic centimeter (g/cm3). For a better experience on this and other websites, we recommend that you enable Javascript. It is advisable to pre-dissolve them in a container of water and splash the resulting solution over the pond surface. Most fertilizers that are commonly used in agriculture contain the three basic plant nutrients: nitrogen, phosphorus, and potassium. Organic fertilizers (livestock manures and other agricultural wastes or by-products) and chemical fertilizers can be applied to aquaculture ponds to increase fish or shrimp production. Fertilizers should be applied to supply 0.5 – 1 mg/l of nitrogen and 0.1 – 0.5 mg/l of phosphate. These systems form the bulk of aquaculture production in Kenya. Some ammonia is lost to the air by diffusion, a part is taken up by plants, and a portion is lost in outflow. In extensive farming systems in Africa and Asia, bamboo poles or tree branches are planted within the ponds to increase natural productivity. Fertilizers usually are applied to ponds on a weight-per-area basis. There are several ways to categorize fertilizer, and the most basic is whether it is organic or inorganic. These types of fertilizers are most often used when growing outdoor plants and houseplants. More chlorophyll blades have more sugar stores in the … Some recommendations may even take into account the pre-fertilization nutrient concentrations. Both chemical and organic fertilizers act by directly stimulating phytoplankton production within the pond. Common organic fertilizers used in aquaculture are poultry, cow and pig dung but cottonseed meal, rice straw and other agricultural waste products can also be used. They are subject to caking when exposure to moisture and should be stored in a dry place. Diammonium phosphate has the grade (18-46-0). Organic fertilizers or manure include all plant and animal materials and their fertilizer value is dependent primarily upon its carbon (C), N, P and potassium (K) content. Liquid fertilizers
