1、Effects of Foliar Fertilization: a Review of Current Status

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.

2、Foliar magnesium application improves sweet corn yield: boosting

To address the knowledge gap in Mg management strategies, we conducted three-season field trials (2021-2022) evaluating foliar spraying with different concentrations of Mg fertilizer under dense planting conditions.

3、HI

In average conditions: apply 2-3 L/ha repeating according to crop needs. HI-Q Ca-Mg foliar fertilizer corrects calcium and magnesium deficiencies to improve fruit quality, photosynthesis, and overall plant performance.

4、(PDF) Influence of Foliar Application of Magnesium on Horticultural

Foliar application of Mg can be recommended for correcting deficiencies because foliar sprays have no long term residual effect and every time fresh applications must be given to each crop.

Apply at the Right Time of Day. Best times: early morning (before 9 AM) or late afternoon (after 4 PM) to avoid sunburn and maximize absorption. If rain falls within 3 hours of application, reapply.

Mineral Nutrition

Foliar sprays of calcium chloride or calcium nitrate supplying approximately 100 ppm Ca (1.5 g/L of the fertilizer salt) once or twice a week are most commonly used for this practice. Magnesium (Mg) is a critical component of the chlorophyll molecule in plants.

During the period of ‘Feizixiao’ litchi fruit pericarp’s full coloring, there is a phenomenon of “sugar withdrawal” in the pulp, and the mixed foliar nutrients of calcium and magnesium (Ca+Mg) can effectively overcome this phenomenon.

When Is the Right Time to Use Cal Mag in Soil for Optimal Plant Growth?

Learn when to use Cal Mag in soil to boost plant health and prevent nutrient deficiencies. Discover the best timing and signs that indicate your plants need calcium and magnesium supplements. Ensure stronger growth and vibrant crops with expert tips on Cal Mag application.

Calcium-magnesium foliar fertilizer is a nutrient supplement designed to enhance plant growth and disease resistance by providing essential elements like calcium and magnesium. its effectiveness depends on proper usage, including adhering to safe application intervals. Below are key recommendations for optimizing its use:

1. Understand Product Guidelines: Before application, thoroughly read the product instructions or consult professionals to grasp proper dosage, compatible crops, and potential side effects. This ensures correct usage tailored to specific needs.

2. Avoid Overapplication: Excessive use of calcium-magnesium fertilizer can disrupt nutrient balance and hinder plant health. Always follow the manufacturer’s recommended dosage to prevent overloading plants with nutrients.

3. Timing Matters: Apply during peak growth stages (e.g., spring and autumn) when plants demand higher nutrients. In summer, increase frequency due to rapid growth; reduce applications in winter when growth slows.

4. Avoid Alkaline Mixing: Do not mix with alkaline substances (e.g., lime, sodium carbonate), as they may form precipitates, reducing nutrient absorption.

5. Optimize Application Method:

   • Liquid Form: Use non-clogging sprayers to evenly coat leaves.
   • Granular Form: Dissolve in water first and apply around roots for thorough absorption.

6. Weather Considerations: Avoid applying in rainy or windy conditions to prevent loss. Water plants after application to aid nutrient uptake.

7. Monitor Plant Response: Observe for signs of stress (e.g., yellowing, wilting). If issues arise, halt applications and adjust strategies.

8. Complementary Fertilization: Combine with other fertilizers (e.g., nitrogen, phosphorus) based on plant stages. Mixing with organic matter (e.g., compost, manure) can enhance efficiency.

9. Environmental Safety: Choose eco-friendly products and properly dispose of packaging to minimize ecological impact.

10. Regular Soil Testing: Periodically analyze soil nutrient levels using testing kits or professional services to refine fertilization plans.

responsible use of calcium-magnesium foliar fertilizer involves adhering to guidelines, balancing application rates, and adapting practices to environmental and plant conditions. Consistent, science-based approaches ensure healthy plant development.
