1、Can Urea Be Used As Foliar Fertilizer? Benefits And Risks

This comprehensive guide delves into the intricacies of using urea as a foliar fertilizer, exploring its benefits, challenges, and practical applications. Urea: A Nitrogen Powerhouse

2、Comparative Efficacy of Foliar Plus Soil Application of Urea versus

Fertilizer is the most important nutrient element in soils and play the most vital role in crop production in Bangladesh. For maximizing the yield of rice, nitrogenous fertilizers are the kingpin in rice farming.

3、UREA foliar spraying: Are there trials with significant positive

Foliar plant spray involves applying fertilizer directly to a plant’s leaves as opposed to putting it in the soil. More concentration of urea can burn the leaf and stem of cereals.

4、Copper

These results clearly indicate that the application of copper-based foliar fertilizer with added zinc and controlled release urea is favorable for tomato.

Conjoint application of nano

Hence, a fixed plot field experiment was conducted to assess the economic and environmental competency of conventional fertilizers with and without nano-urea (novel fertilizer) in two predominant cropping systems viz., maize-wheat and pearl millet-mustard under semi-arid regions of India.

Replacing soil-applied nitrogen fertilizer with foliar-applied urea contributes to fertilizer best management practices and reduces the potential for nitrogen to negatively impact the environment and human health.

Improving nutrient use efficiencies with foliar applied nutrients

Urea is a particularly effective source of N to consider for foliar application, as it is highly and rapidly absorbed across the waxy cuticle – urea is the easiest form of artificial N for the leaves to absorb followed by ammonium, then nitrate.

Research progress in uptake and metabolism of foliar urea in plants

The effectiveness of foliar application and the efficient assimilation of urea by leaves are influenced by various factors, including foliar structure, environmental conditions, and carbon-nitrogen metabolism.

Effect of foliar application of urea on the growth and yield of tomato

Results showed that different yield components and yield of tomato were influenced by the foliar application of different concentrations of urea.

Co

Humic substances (HS) and humic acids (HA) are proven to enhance nutrient uptake and growth in plants. Foliar application of urea combined with HS and HA offers an alternative strategy to increase nitrogen use efficiency (NUE).

Foliar fertilizer and urea are two commonly used agricultural fertilizers. Foliar fertilizer is a nutritional supplement applied by spraying onto plant leaves to provide essential nutrients. Urea, a nitrogen-based fertilizer, primarily promotes plant growth and increases yield. Combining foliar fertilizer with urea leverages their complementary effects, enhancing plant growth rates and productivity.

1. Roles of Foliar Fertilizer

Foliar fertilizer supplies essential nutrients such as nitrogen (N), phosphorus (P), and potassium (K), which are critical for plant growth and development. These nutrients improve photosynthetic efficiency, facilitate nutrient transport and distribution, and enhance growth speed and stress resistance. Additionally, foliar fertilizer optimizes plant nutrition, improving fruit quality and yield.

2. Roles of Urea

Urea is a nitrogen-rich fertilizer that replenishes soil nitrogen, stimulating plant growth and yield. Through microbial action, urea converts into ammonia, which plants absorb. It also regulates soil pH, enhancing water retention and air permeability.

3. Complementary Effects of Foliar Fertilizer + Urea

Foliar fertilizer and urea complement each other. While foliar fertilizer provides direct nutrients, urea transforms soil nitrogen into plant-available forms. This synergy accelerates growth, boosts yields, and reduces reliance on soil fertilization.

4. Application Methods

Foliar fertilizer and urea can be used separately or combined. A typical ratio is 1:1 or 1:2 (e.g., 5–10 kg foliar fertilizer + 10–20 kg urea per mu). Dissolve urea in water before spraying it onto leaves.

5. Effectiveness Evaluation

Combining foliar fertilizer and urea typically increases growth speed and yield. Foliar fertilizer supplies essential nutrients, while urea ensures nitrogen availability. This combination also improves plant nutrition, fruit quality, and overall productivity.

6. Precautions

• a. Choose formulations suited to the plant’s growth stage.
• b. Follow recommended dosages to avoid nutrient excess.
• c. Ensure even leaf coverage during spraying.
• d. Adjust application rates based on plant conditions and soil environment.
• e. Monitor plant responses and address abnormalities promptly.

Combining foliar fertilizer with urea is an effective strategy to boost plant growth and yields. Proper use optimizes nutrient management and supports sustainable agricultural development.
