1、Calcium chloride treatment delayed the softening of postharvest

Addressing the postharvest softening of blueberries has been a pivotal concern for the industry, impacting economic viability and consumer satisfaction. Recent advancements in preservation techniques have sought to alleviate this issue through various methods.

2、The Effect of Foliar Calcium Spraying on Changes in the

One method to extend the shelf life of blueberries is foliar fertilisation with calcium, which can enhance mechanical parameters after harvest.

3、Timing of Foliar Calcium Sprays Improves Fruit Firmness and

Several blueberry management practices influence both productivity and fruit quality, including pruning, irrigation, plastic covers usage, and nutrition (Retamales and Hancock 2018).

4、Grow Better Blueberries with Haifa products

Urea and controlled release fertilizers are also suitable sources of nitrogen for blueberries In the soil, urea is a rapidly converted to ammonium, which is readily absorbed by the plant

Micronutrient Deficiencies in Blueberries and Their Correction

Sodium: can be a problem, toxic to blueberries at high levels, SAR (Sodium Adsorbtion Ratio) below 4 is desirable, generally not a problem. But some salty areas are present in Fla.

Calcium Chloride Treatment Inhibited Postharvest Blueberry Softening by

In recent years, advancements in preservation techniques have been developed to mitigate postharvest softening, with calcium chloride (CaCl2) treatment emerging as a potential approach.

Foliar Calcium in Blueberries: Silver Bullet or Snake Oil?

Because of the preferential movement of calcium to leaves instead of where we often want it (i.e., the fruit), growers will apply foliar calcium with the goal of getting more calcium directly into the fruit.

Suggested Fertilizer Practices For Blueberries

Use dolomitic limestone that contains magnesium as well as calcium if it is necessary to raise the soil pH. If the soil test results for magnesium are in the below optimum category but limestone is not recommended, apply 10 ounces of Epsom salts per 100 sq. ft.

CALCIUM FOR BLUEBERRIES — The Fertrell Company

As calcium can only move through the xylem, calcium uptake runs into a problem because blueberry plants shut off the xylem as the berries grow, preventing any more calcium uptake. One option is to apply gypsum to the base of the plant.

Calcium impregnation during isochoric cold storage to improve

Isochoric cold storage can be used to extend the shelf-life of fresh produce by delaying senescence through storage at subfreezing temperatures as well as hinder microbial growth with pressure.

If blueberry plants exhibit abnormal conditions after spraying with calcium-magnesium-boron fertilizer, prompt action is necessary. The following recommendations may help address the issue:

1. Inspect Plant Growth: First, carefully observe the growth status of the blueberry plants. Symptoms such as yellowing, wilting, or spotting on leaves may indicate improper use of the fertilizer. In such cases, halt fertilization immediately and take corrective measures.

2. Adjust Fertilizer Ratios: If plants appear generally healthy but show mild symptoms, the fertilizer ratio might be imbalanced. Consider increasing the proportion of nitrogen-based fertilizers to promote recovery and growth. Avoid over-fertilization, which could harm the plants.

3. Improve Soil Management: Enhance soil conditions by regularly deep-tilling and loosening the soil to improve aeration and water retention. Maintain consistent moisture levels, avoiding extremes of drought or waterlogging. Incorporating organic fertilizers can also enrich soil quality.

4. Monitor Weather Conditions: Blueberries are sensitive to environmental factors, particularly temperature and humidity. After fertilization, protect plants from harsh weather (e.g., heatwaves, heavy rain) by using shade structures, adjusting irrigation, or other protective measures.

5. Strengthen Pest and Disease Control: Closely monitor plants for signs of pests or diseases. If detected, apply fungicides, insecticides, or other appropriate treatments promptly. Physical methods like pruning diseased branches or removing affected leaves may also be necessary.

6. Prune Branches Appropriately: During the growing season, pruning enhances air circulation and reduces disease risk. Retain main stems and healthy side branches while removing weak, crossing, or diseased branches. Thin flowers and fruits as needed to ensure quality and yield.

7. Optimize Fertilization Timing and Methods: Apply fertilizers at appropriate times and doses. Increase fertilization in spring (critical growth phase), reduce it in summer (to avoid root burn), and apply phosphorus-potassium fertilizers in autumn to improve fruit maturation. Avoid fertilizing during rainy periods to prevent soil erosion and nutrient loss.

8. Select Suitable Varieties and Cultivation Practices: Choose blueberry varieties suited to local climates and soil types. Adopt best practices, such as optimal planting density, scientific irrigation, and timely fertilization, to maximize yield and fruit quality.

addressing abnormalities after calcium-magnesium-boron fertilizer application requires a holistic approach. Combining proper fertilization, soil care, environmental management, and cultivation techniques ensures healthy blueberry growth and high-quality yields.
