1、Calcium Fertilizers

Calcium fertilizer is defined as a substance that supplies calcium to soil and plants, with common sources including calcium carbonate, calcium hydroxide, and calcium oxide.

2、How to Successfully Apply Calcium Fertilizer Through Root Irrigation

Commercial foliar calcium sprays (calcium acetate, calcium nitrate, and calcium chloride) are the quickest remedy for acute calcium deficiency, as plants absorb nutrients more efficiently through leaves than through roots.

3、Preparation of calcium

Composting of BA with organic matter is an effective strategy, but the composting cycle is long and there is a large amount of insoluble residue in the product. Therefore, this research proposed for the first time using the hydrothermal method to rapidly convert BA and bamboo powder (BP) into water - soluble fertilizer (WSF) within 4 h.

Application of chelated fertilizers to mitigate organic

This study hypothesizes, chelating fertilizers-based adsorption removing Ca 2+ binding with organic fouling, reducing potential interaction between organic and inorganic fouling. However, the interaction mechanisms of chelated fertilizer effects multiple fouling are still elusive.

Application of calcium peroxide in water and soil treatment: A review

Calcium peroxide (CP) has been progressively applied in terms of environmental protection due to its certain physical and chemical properties. This review focuses on the latest progresses in the applications of CP in water and soil treatment, including wastewater treatment, surface water restoration and groundwater and soil remediation.

Fertilizers and nitrate pollution of surface and ground water: an

While a small portion may directly leach down and may reach ground and surface water bodies, a large proportion ends up in the soil organic N pool from where N is mineralized and is taken up by plants and/or lost via leaching during several decades.

Interaction and adaptation of phosphorus fertilizer and calcium ion in

To mitigate emitter clogging of PDIS, it is suggested that phosphorus fertilizer types and suitable Ca 2+ concentrations be adapted, as well as water filtration should be enhanced.

Impact of fertilizers on aquatic ecosystems and protection of water

Fertilizer use, its impact on water bodies and their pro- tection are comprehensively discussed in this contribu- tion.

How To Apply Calcium Ammonium Nitrate Fertilizer

For disease prevention or nutrient balance, mix one tablespoon of calcium nitrate per gallon of water. If using granular forms, incorporate it into the soil, avoiding contact with plant leaves, and water the area well to facilitate nutrient absorption.

What are Calcium

Mitigating this by applying calcium in the right rate, form, place and time (the 4R of nutrient stewardship) can help offset nutrient losses and ensure the fertilizers we put down are available to be taken up.

Applying calcium fertilizers in water bodies involves introducing calcium-containing compounds to replenish calcium ion concentrations, maintain or improve water quality. Calcium is an essential mineral for aquatic life, playing a critical role in sustaining ecological balance, promoting plant growth, and preventing excessive algal proliferation. Below are detailed steps and precautions for applying calcium fertilizers in water bodies:

1. Selecting the Appropriate Type of Calcium Fertilizer

• Calcium Carbonate (CaCO₃): A common choice, but its large particle size requires grinding or dissolution before plants can absorb it.
• Calcium Sulfate (CaSO₄): Highly soluble and easily absorbed by plants, but may pose toxicity risks to fish and certain organisms. Use with caution.
• Calcium Chloride (CaCl₂): Less soluble than the above options, but applicable under specific conditions.

2. Determining the Application Rate

• Calculate dosage based on factors such as water body area, depth, flow rate, temperature, pH, and existing calcium levels.
• Start with incremental doses, observing plant responses and water quality changes to refine application strategies.

3. Application Methods

• Dissolution Method: Dissolve calcium compounds (e.g., CaCO₃, CaSO₄, CaCl₂) in water, then evenly distribute the solution across the water surface or spray it using irrigation systems. Monitor pH and temperature to ensure optimal dissolution.
• Soaking Method: Mix calcium fertilizer with soil and spread it on the water surface to form a thin layer. Plants absorb calcium through roots. Suitable for shallow waters; avoid runoff.

4. Safety and Environmental Protection

• Wear protective gear to avoid exposure to harmful substances. Prevent overapplication to avoid water contamination.
• Comply with local environmental regulations to minimize ecological risks.

5. Monitoring Water Quality

• Regularly test pH, hardness, dissolved oxygen, and other metrics during and after application to ensure water quality standards.
• Evaluate the effectiveness and potential side effects of calcium fertilization.

6. Balancing Nutrients

• Coordinate calcium applications with other essential nutrients (e.g., nitrogen, phosphorus, potassium) to maintain nutritional balance.
• Adjust strategies flexibly based on real-time conditions.

7. Long-Term Management and Innovation

• Refine application practices through ongoing experience and scientific adjustments.
• Explore sustainable, eco-friendly alternatives to traditional calcium fertilizers as technology advances.

Fertilizing water bodies with calcium requires a systematic approach that considers hydrological conditions, ecological needs, and environmental impacts. Scientific management and continuous improvement can enhance water quality and promote the health and stability of aquatic ecosystems.
