This article will comprehensively analyze the core technologies of foliar fertilizer application from basic principles to practical key points, providing scientific guidance for agricultural producers.

Foliar Fertilization: An Approach To Enhance Nutrient Use Efficiency

Foliar fertilizer applications increases plant growth, fruit set and yield in case of limited availability of nutrients essential for flowering and fruit set due to reduced transpiration and/or nutrient acquisition by the roots.

Foliar fertilizers and their use to enhance yield and quality

When used correctly, foliar fertilizers can enhance yield, quality, and overall plant health. Here’s how foliar fertilizers can be used to achieve these goals:

Improving nutrient use efficiencies with foliar applied nutrients

Among many strategies that can play a role toward improving nutrient use efficiencies [NUE], foliar application of plant available nutrients has emerged as one potential tool that can play an important role in integrated nutrient management.

ALL FOLIAR FERTILIZATION CAN AND SHOULD RESULT IN A YIELD BENEFIT AND

With the increasingly high cost of fertilizer, replacing soil-applied fertilizers in part with properly timed foliar fertilizers provides growers with a tool to reduce fertilizer use and expense while increasing yield and revenue and protecting the environment.

Green onions (Allium fistulosum) are widely cultivated globally due to their large leaf area, fast growth rate, and high nutrient demands. To enhance growth quality and yield, applying foliar fertilizers is an effective strategy. Selecting the right fertilizer requires careful consideration of its composition, mechanism of action, application methods, and potential effects. Below is a detailed overview of commonly used foliar fertilizers for green onions.

I. Water-Soluble Fertilizers (e.g., Potassium Dihydrogen Phosphate)

1. Composition and Mechanism: Water-soluble fertilizers contain essential nutrients like nitrogen (N), phosphorus (P), and potassium (K). These elements are critical for plant growth and development. When sprayed onto leaves, they are directly absorbed, promoting rapid growth and metabolic processes.

2. Application Method: Dissolve the fertilizer in water and evenly spray it over the leaves. Apply every two weeks for three consecutive applications.

3. Effectiveness:

   • Accelerates growth rate and strengthens stems.
   • Enhances leaf color (lush, green foliage) and improves yield.

II. Amino Acid-Based Compound Fertilizers

1. Composition and Mechanism: These fertilizers contain multiple amino acids, which stimulate cell division, root growth, and photosynthesis. They also boost disease resistance and drought tolerance.

2. Application Method: Dilute to the recommended concentration and spray evenly on leaves. Apply every two weeks for three consecutive applications.

3. Effectiveness:

   • Significantly increases growth rate and leaf glossiness.
   • Improves yield while reducing susceptibility to diseases.

III. Microelement Fertilizers

1. Composition and Mechanism: These fertilizers supply trace elements like iron (Fe), zinc (Zn), copper (Cu), and manganese (Mn), which are vital for enzymatic reactions, photosynthesis, and nutrient uptake.

2. Application Method: Dilute to the appropriate concentration and spray evenly on leaves. Apply every two weeks for three consecutive applications.

3. Effectiveness:

   • Enhances overall plant health and leaf robustness.
   • Prevents deficiency-related disorders and boosts yield.

Selecting the optimal foliar fertilizer depends on the specific nutritional needs of green onions at different growth stages. Combining water-soluble, amino acid-based, and microelement fertilizers can maximize yield and quality. Proper application techniques and adherence to recommended dosages ensure efficient nutrient absorption and minimal environmental impact.
