1、Foliar nutrition: Potential and challenges under multifaceted

Foliar fertilization has been well recognized for two decades to affect crop productivity, however, the consequences of foliar spray under multiple environmental stresses remains elusive, albeit evidence to resilience agriculture has grown widely.

2、Effects of Foliar Fertilization: a Review of Current Status and Future

Compared with root fertilization, foliar fertilization, as a supplementary fertilization strategy, can deliver nutrients directly to the target through aerial plant parts, thereby helping to reduce negative impacts on the soil (Bindraban et al. 2015; Fernández and Eichert 2009).

Soil applications of fertilizers are mainly done on the basis of soil tests, whereas foliar nutrient applications are mainly done on the basis of visual foliar symptoms or plant tissue tests. Hence, correct diagnosis of nutrient deficiency is fundamental for successful foliar fertilization.

Foliar fertilization requires higher leaf area index for absorbing applied nutrient solution in sufficient amount, it may be necessary to have more than one application depending on severity...

5、Effects of Foliar Fertilization: a Review of Current Status and Future

Foliar fertilizer application after soil fertilization is an effective method to increase the contents of trace elements in crops and crop yield, and to improve the soil environment. However, the application of inorganic foliar fertilizer results in difficulties in nutrient absorption and migration in plants.

Research Progress on Role and Mechanisms of Foliar Fertilizer in

Finally, the problems existing in the practical application of foliar fertilizers and the prospects for further exploring the mechanism by which foliar fertilizers regulate plant growth and development are discussed and prospected.

Foliar fertilizers: Enhancing nutrient uptake for healthy plants

Foliar fertilization bypasses the soil altogether, minimizing the risk of nutrient interactions and ensuring that plants receive nutrients in their most bioavailable forms.

Foliar application of bioorganic fertilizer enhances plant nutrients

The enzyme activity has greatly increased with bioorganic fertilization, demonstrating that foliar application directly influence the soil enzymes in the rhizosphere.

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.

From plant surface to plant metabolism: the uncertain fate of foliar

While variable effectiveness is often seen in response to foliar treatments, there is abundant evidence showing the beneficial effect of foliar fertilizers in terms of improving the metabolism, quality, and yields of crops.

Foliar fertilization after the survival of bare-rooted plants is feasible and highly beneficial in certain situations. Foliar fertilization (also known as spraying or foliar spraying) is a method of directly applying nutrients to plant leaves, which can rapidly provide essential nutrients to promote plant growth and increase yields.

Nutritional Needs After Survival of Bare-Rooted Plants

After rooting and survival, the nutritional needs of plants change, especially for seedlings with shallow roots or weak absorption capacity. Timely nutrient supplementation is particularly important. If soil nutrients are insufficient or soil conditions are unfavorable for root development, foliar fertilization can quickly replenish these nutrients.

Selection and Application Methods of Foliar Fertilizers

1. Types of Foliar Fertilizers: There are various types of foliar fertilizers on the market, including nitrogen fertilizers (e.g., urea), phosphorus fertilizers (e.g., superphosphate), potassium fertilizers (e.g., potassium sulfate), and microelement fertilizers. Choose fertilizers based on the specific growth stage and nutritional needs of the plants.

2. Application Frequency: It is generally recommended to apply foliar fertilization once within the first week after survival to help the plants recover vitality and adapt to the new environment. Subsequent applications should depend on the plant’s growth condition and soil test results.

3. Concentration: The concentration of foliar fertilizers should not be too high to avoid leaf burn. A low concentration, such as 0.2% to 0.5%, is typically recommended.

4. Timing: Apply foliar fertilization in the morning or evening when stomata are open, facilitating nutrient absorption. Avoid applying during hot midday hours, as high temperatures may accelerate nutrient loss.

5. Application Method: Dilute the foliar fertilizer and spray it evenly over the leaves using a sprayer. Avoid spraying directly onto stems or roots to prevent damage.

Precautions

1. Fertilizer Type: Choose safe and effective fertilizers, avoiding harmful chemical compounds.

2. Soil Conditions: Check soil pH and nutrient content before applying foliar fertilizers to ensure optimal growing conditions.

3. Plant Health: If plants exhibit yellowing, wilting, or other abnormal symptoms, rule out other causes before considering improper foliar fertilization.

4. Over-Fertilization: While foliar fertilization provides quick nutrition, excessive application can harm plants. Determine the appropriate amount based on actual needs and soil fertility.

5. Environmental Factors: Avoid fertilization during extreme weather (e.g., high heat, drought, or cold) to prevent growth disruption.

Foliar fertilization after the survival of bare-rooted plants is an effective method for supplementing nutrients, particularly for plants with weak roots. proper application methods and precautions are critical. With rational fertilization, plants can recover better, survive at higher rates, and establish a strong foundation for future growth.
