Trace elements are extremely important and crucial to plant growth. So, what are the trace element water-soluble fertilizers that have emerged on the market in recent years? What are their benefits that have earned them such widespread acclaim from farmers? Let's take a closer look at trace element water-soluble fertilizers.
1. What are trace element water-soluble fertilizers?
Trace element water-soluble fertilizers generally refer to fertilizers containing trace nutrients, such as boron (B), manganese (Mn), molybdenum (Mo), copper (Cu), zinc (Zn), and iron (Fe). Trace elements play a crucial role in plant growth and development that cannot be replaced by larger quantities. Scientifically increasing the application of trace element fertilizers is crucial for normal plant growth and high and stable crop yields. Trace element water-soluble fertilizers currently account for a significant portion of crop fertilization. II. The Role and Characteristics of Trace Element Water-Soluble Fertilizers
Although crops require minimal trace elements, they play crucial physiological roles. With the exception of boron and chlorine, most trace elements are components of certain enzymes. Trace elements actively participate in carbohydrate and protein metabolism in plants; contribute to chlorophyll synthesis and stabilization; participate in redox reactions in crops; and promote biological nitrogen fixation. Elements interact with each other in both synergistic and antagonistic ways, making balanced supplementation crucial. Trace element formulas must be tailored to the characteristics of the crop and soil. Different trace element formulas are tailored to their specific functions. For example, in addition to general formulas, water-soluble trace element fertilizers are also available for specific applications during flowering, fruit set, vegetative organ growth, preventing seedling drop and cracking, and promoting coloration. Each formula has its own specific focus and specific characteristics. III. Precautions for Applying Water-Soluble Trace Element Fertilizers
1. Apply water-soluble trace element fertilizers based on soil, climate, and crop absorption patterns. Generally, low trace element levels in the soil are more likely to cause deficiencies, so the principle of addressing the deficiency should be adopted to achieve optimal results. Different crop species have varying sensitivities to trace element fertilizers and require varying amounts. For example, cabbage, rapeseed, brassicas, and radish are sensitive to boron fertilizers and require high amounts. A specific fertilizer application plan should be developed based on your crops and environment, determining the optimal dosage.
2. Combine water-soluble trace element fertilizers with organic fertilizers. Combining organic and chemical fertilizers can enhance soil microbial activity, promote further decomposition of organic fertilizers, and release large amounts of carbon dioxide and organic acids. This combination also significantly dissolves insoluble nutrients in the soil, making them available for crop absorption and utilization.
3. Apply the right amount based on the location and symptoms of the deficiency. For example, trace element deficiencies often occur in newly grown leaves. Trace elements are required in very small quantities and are easily fixed by the soil. Foliar sprays are generally more effective than soil applications.
4. Pay attention to application rate and concentration. Crops require very small trace elements, and the range from adequate to excessive is very narrow. Therefore, it is important to avoid excessive micronutrient fertilizer applications. Soil application must be uniform, otherwise it can cause plant poisoning and pollute the soil and the environment.
5. Focus on improving soil environmental conditions. Trace element deficiencies are often not due to low trace element content in the soil, but rather to low trace element availability. By adjusting soil conditions such as soil pH, soil texture, organic matter content, and soil moisture content, the soil's trace element nutritional status can be effectively improved.
6. Combine trace element fertilizers with macronutrient fertilizers. Trace elements are equally important and irreplaceable as nutrients like nitrogen, phosphorus, and potassium. Only when the plant's macronutrient requirements are met can the application of trace element fertilizers be effective and significantly increase yields.
