The quantity 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, it's essential to take several factors into account and apply fertilizers wisely.
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. Higher temperatures generally increase the vitality of these organisms, leading to more efficient nutrient uptake. Conversely, lower temperatures slow down metabolism, reducing fertilizer efficiency.
Studies have shown that the breakdown of organic components in "Tianchen Fishery Fertilizer" by bacteria varies with water temperature. At higher temperatures, decomposition is faster, resulting in quicker fertilizer effects. After fertilization, the timing of plankton blooms also depends on temperature and weather. For instance, when the water is around 22°C and the weather is clear, the water color typically meets the required standards within 2–3 days. However, if rain follows fertilization, the drop in temperature and reduced light can slow down both organic decomposition and plankton growth. In such cases, it may take 5–6 days before the water becomes "fertile," so it's best not to assume the fertilizer was insufficient and to wait for clearer weather before applying more.
Second, pH levels play a crucial role in fertilization success. Fertilization is most effective in neutral or slightly alkaline waters, where plankton populations grow rapidly and in large numbers. If the pond has excessive silt, leading to acidic conditions, microbial activity is impaired, slowing the breakdown of organic matter. This makes fertilization less effective. To address this, removing excess silt and using lime to adjust the pH can help restore proper conditions before applying other fertilizers.
Third, dissolved oxygen (DO) is another critical factor. Fertilization and oxygen levels are closely linked. Insufficient fertilization leads to thin water with high oxygen content but limited natural food. Over-fertilization, however, can pollute the water and reduce oxygen levels, which harms aquatic life. It's important to find a balance—ensuring the water is rich in nutrients without causing oxygen depletion.
Organic fertilizers, especially uncomposted ones, consume a lot of oxygen during decomposition. Excessive use can lead to oxygen depletion, causing fish to float or even die. Composting organic fertilizers beforehand breaks them down into simpler compounds, reducing oxygen demand and improving efficiency. Inorganic fertilizers, on the other hand, promote rapid phytoplankton growth, which helps increase dissolved oxygen through photosynthesis. However, over time, inorganic fertilizers can make the water "old," negatively affecting aquatic life.
High dissolved oxygen supports beneficial aerobic bacteria like nitrogen-fixing and nitrifying bacteria, enhancing fertilizer efficiency. It also boosts the metabolism of aquatic animals, promoting faster growth and better yields. Low oxygen levels, however, encourage harmful anaerobic bacteria, which produce toxic substances like hydrogen sulfide and ammonia, reducing productivity.
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 water quality. It keeps the water "fertile, lively, soft, and cool" for an extended period.
Lastly, soil and sediment composition significantly influence fertilization outcomes. Different soils vary in structure, chemical makeup, and nutrient retention. Before fertilizing, it's important to assess the pond's soil conditions. The soil should retain water well to maintain consistent water levels and fertility. It should also contain inorganic substances that affect water quality and some organic matter that decomposes into nutrients for the water. Humus, a special organic component, provides essential nutrients and binds minerals, playing a vital role in maintaining water health.
In summary, understanding the physical and chemical conditions of the pond before fertilizing is key. Improving poor conditions, adjusting pH, and increasing dissolved oxygen are all effective ways to enhance fertilizer performance.
