1、钙肥_百度百科
calcium fertilizer具有钙（Ca）标明量的肥料。 施入土壤能供给植物钙，并有调节土壤酸度的作用。 钙肥的主要品种是石灰，包括生石灰、熟石灰和石灰石粉。 石膏及大多数磷肥，如钙镁磷肥、过磷酸钙等和部分氮肥如硝酸钙、石灰氮等也都含有相当数量的钙。
2、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.
3、Which Calcium Fertilizers Are Most Effective?
Nano fertilizers application is the most effective way to address nutritional shortages and improve crop quality and yield over traditional fertilizers. Nano-Ca has a large surface area, bioavailability, and controlled release to specific areas.
4、Comparison of Five Mainstream Calcium Fertilizers, Including EDTA
EDTA-chelated calcium (calcium disodium ethylenediaminetetraacetic acid) is currently the most efficient calcium fertilizer and exhibits high activity. Calcium can be transported up and down the plant body along with the flow of cellular sap, transporting calcium to all parts of the crop.

ICL Growing Solutions – This site details various calcium-based fertilizers and their applications, such as calcium carbonate, calcium nitrate, and calcium chloride.
What are Calcium
Using calcium fertilizers to supplement soil calcium levels and address specific crop needs can help prevent deficiencies and reduce the risk of crop loss due to physiological disorders.
What Fertilizer Is High In Calcium? (6 Calcium Fertilizers To Try)
What Fertilizer Is High In Calcium? Here is a table with some of the best fertilizers with high calcium content. You can find more detail about each type of calcium fertilizer after the table.
The Best and Safest Way to Apply Calcium Fertilizers
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.
Calcium fertilisers: why and when should they be used?
Calcium oxide fertilisers, whose use is recommended primarily on moist soils. This type of mineral product is most often applied by farmers in spring, before sowing crops. As we mentioned, oxide fertilisers are reactive and corrosive: these properties enable them to destroy harmful microorganisms.
Best Calcium Fertilizers for Healthy Plant Growth and Prevention 2026

Calcium fertilizers are indispensable in agricultural production, providing essential nutrients for plant growth and development. When selecting calcium fertilizers, safety and efficacy are the most critical considerations. Below are some recommendations for choosing and using calcium fertilizers:
I. Safety of Calcium Fertilizers
1. Inorganic Calcium Fertilizers
Inorganic calcium fertilizers, such as calcium chloride (CaCl₂) and gypsum (CaSO₄), contain no organic matter. They have minimal impact on soil environments, unlike organic fertilizers, which may attract pests or disrupt soil structure. Thus, inorganic calcium fertilizers are generally safer to use.
2. Organic Calcium Fertilizers
Organic calcium fertilizers, such as lime (CaO) and phosphogypsum, improve soil structure but often have high alkalinity. Excessive use can damage plant roots. Additionally, organic components may attract pests, increasing disease risks. These fertilizers require cautious and controlled application.
II. Effectiveness of Calcium Fertilizers
1. Types of Calcium Fertilizers
Various calcium fertilizers are available, including calcium chloride, gypsum, calcium nitrate (Ca(NO₃)₂), and calcium phosphate. The choice depends on crop type and soil conditions. For example, calcium chloride suits acidic soils, while gypsum is better for alkaline soils. Selecting the appropriate fertilizer enhances nutrient uptake and efficiency.
2. Application Rates
Dosage should align with crop requirements and soil conditions. Overuse can lead to soil salinization, hindering plant growth. Follow recommended guidelines and adjust based on specific needs.
3. Application Methods
Calcium fertilizers should be evenly applied—either sprayed as a solution or incorporated into the soil. Avoid mixing with acidic substances to prevent chemical reactions. Additionally, refrain from applying during hot weather to avoid "root burning" caused by rapid evaporation.
III. Key Considerations for Using Calcium Fertilizers
1. Soil Conditions
Soil pH, texture, structure, and nutrient content influence fertilizer selection. Acidic soils benefit from calcium sulfate, while alkaline soils pair better with calcium chloride.
2. Crop Requirements
Calcium needs vary by crop and growth stage. For example, calcium is critical during seedling and flowering stages for growth and disease resistance. excessive calcium during harvesting may reduce fruit quality or yield.
3. Environmental Protection
Excessive use of calcium fertilizers can cause soil salinization or groundwater contamination. Adhere to environmental standards and regulations to minimize ecological harm.
The safest and most effective calcium fertilizer depends on balancing safety, efficacy, and sustainability. Inorganic options are generally safer but require soil and crop compatibility checks. Organic alternatives improve soil health but demand careful management. Prioritize soil conditions, crop needs, and environmental stewardship to ensure optimal results and sustainable agriculture.
