The amount of natural food organisms in a water body is influenced and limited by various physical, chemical, and biological factors. Among these, fertilization plays a significant role. However, the effectiveness of fertilization itself is also impacted by environmental conditions. To achieve the desired results, several key factors must be carefully considered and applied rationally.
First, water temperature has a direct impact on the metabolic activity of aquatic organisms, which in turn affects their ability to absorb and utilize fertilizers. When the water is warmer, aquatic life becomes more active, metabolism increases, and the absorption of nutrients from fertilizers improves. Conversely, lower temperatures can slow down this process.
Studies have shown that the decomposition of organic components in "Tianchen Fishery Fertilizer" by bacteria is highly dependent on water temperature. At higher temperatures, decomposition occurs more rapidly, leading to quicker fertilizer effects. After applying fertilizer, the peak growth of plankton also varies depending on the temperature and weather. For instance, at around 22°C with clear skies, the water color typically meets the desired standards within 2–3 days after proper fertilization. However, if it rains after application, the drop in temperature and reduced light can slow down both the decomposition of organic matter and plankton growth. In such cases, it may take up to 5–6 days for the water to become "fertile," and it's important not to rush into applying more fertilizer immediately. Instead, wait for a few days until the weather clears before making further decisions.
Second, pH levels significantly influence the effectiveness of fertilization. In neutral or slightly alkaline waters, fertilization yields the best results, as plankton populations grow fastest and most abundantly. If the pond has excessive silt, the water may become highly polluted, and the soil and water could become acidic. This hinders microbial activity and slows down the breakdown of organic matter. In such situations, removing excess silt and using lime to adjust the pH can help restore balance before applying other fertilizers.
Third, dissolved oxygen (DO) is another critical factor. Fertilization and oxygen levels are closely linked—too little fertilizer leads to poor water quality, while too much can cause pollution and reduce oxygen levels. It's essential to maintain an appropriate balance so that the water remains rich in nutrients without becoming harmful to aquatic life. Organic fertilizers, especially uncomposted ones, consume a lot of oxygen during decomposition. Overuse can lead to oxygen depletion, causing fish to float or even die. Therefore, it’s important to compost organic materials first, breaking them down into simpler compounds that release nutrients gradually and minimize oxygen consumption. In contrast, inorganic fertilizers do not require decomposition and promote rapid phytoplankton growth, which helps increase oxygen levels through photosynthesis. However, over time, inorganic fertilizers can make the water "old," reducing its productivity.
Dissolved oxygen also supports beneficial aerobic bacteria, such as nitrogen-fixing and nitrifying bacteria, which enhance fertilizer efficiency. High oxygen levels improve the metabolism of aquatic animals, promoting faster growth and better yields. On the other hand, low oxygen can lead to the proliferation of harmful anaerobic bacteria, producing toxic substances like hydrogen sulfide and ammonia, which negatively affect the ecosystem.
Using "Tianchen Fishery Fertilizer" can help address many of these issues. It combines the benefits of traditional and inorganic fertilizers, effectively improving dissolved oxygen and maintaining water quality. It keeps the water "fertile, lively, soft, and cool" for extended periods.
Lastly, the condition of the soil and sediments in the pond should not be overlooked. Different soils vary in texture, chemical composition, and nutrient retention capacity. Before fertilizing, it's crucial to assess the soil’s ability to hold water, its mineral content, and its organic matter. The presence of humus in the soil is particularly beneficial, as it provides nutrients and helps bind minerals, enhancing overall fertility.
In summary, understanding the physical and chemical conditions of the pond before fertilization is essential. Improving water quality, adjusting pH, and increasing dissolved oxygen are all effective strategies to maximize the benefits of fertilization.
