3、Carbonates and bicarbonates: A sustainable approach for managing plant

Carbonates and bicarbonates (e.g., NaHCO3, KHCO3, CaCO3) offer a promising, Generally Recognized as Safe (GRAS) alternative for integrated pest and disease management and abiotic stress mitigation.

4、IMPROVEMENTS ON THE QUALITY OF AMMONIUM

NH^HCOj is the widely used nitrogenous fertilizer in our country* It is suitable for various kinds of soils. It has no detrimental acid ions. It has been proved effective in raising the crop yield. However, NH^HCO^ has its inherent shortcomings: low nitrogen content, easy to decompose and volatize, high water content and easy caking tendency.

Characteristics and management of individual macro-nutrients (nitrogen, phosphorus, and potassium) most often needed as fertilizers are discussed in detail, and secondary nutrients and micro-nutrients are briefly reviewed, with some important examples.

Comprehensive Guide to Nitrogen, Phosphate, and Potassium Fertilizers

Chemical fertilizers are characterized by high nutrient content and fast effects, but they also have some limitations, such as potential negative impacts on soil structure. This article will introduces nitrogen fertilizers, phosphorus fertilizers, and potassium fertilizers first.

ABC Fertilizer: An Outdated or Innovative product

This paper describes one of the oldest nitrogen fertilizers: ABC or Ammonium BiCarbonate. More than 500 plants in China already produce ABC, which is mainly used as fertilizer.

Ammonium Bicarbonate in Agriculture & Fertilizer Uses

As sustainable agriculture gains importance, the use of ammonium bicarbonate has decreased in favor of more efficient fertilizers. However, it is still used in certain regions where lower cost and specific soil conditions make it a suitable option.

Ammonium Bicarbonate in Agriculture and Fertilizer Applications

In some cases, ammonium bicarbonate is blended with other fertilizers to reduce cost and enhance nitrogen availability during early crop stages. Ammonium bicarbonate contains a relatively...

Ammonium bicarbonate used as a nitrogen fertilizer in China

NH 4 HCO 3 pills weighing about 1 g are used to overcome the poor physical properties of the NH 4 HCO 3 powder. Extensive field experiments laid down on various soil areas in China showed good crop responses when NH 4 HCO 3 pills were deep dressed.

Both ammonium bicarbonate (carbon铵) and potassium fertilizer are commonly used in agriculture, but they differ in their soil functions and application methods. Below is a detailed comparison of the characteristics of these two fertilizers to help you make an informed decision.

I. Characteristics and Advantages of Ammonium Bicarbonate

1. Nitrogen Content: Ammonium bicarbonate is a nitrogen-based fertilizer containing a high percentage of nitrogen (N). It is suitable for scenarios requiring rapid nitrogen supplementation, such as topdressing after spring planting.

2. Ease of Use: It is typically granular or powdered, making it easy to store and apply. It can be directly spread or mixed with soil.

3. Cost-Effectiveness: Due to lower production costs, it is more economical, making it a practical choice for small-scale farmers or those with limited budgets.

4. Environmental Impact: Its production may cause environmental issues, such as greenhouse gas emissions and solid waste management challenges. Local environmental regulations should be considered during use.

5. Suitable Crops: It is ideal for nitrogen-loving crops like rice, corn, and potatoes, promoting growth and yield improvement.

II. Characteristics and Advantages of Potassium Fertilizer

1. Potassium Content: Potassium fertilizer contains potassium (K) in forms like potassium chloride or sulfate. Potassium is critical for plant development, enhancing disease resistance, fruit quality, and root growth.

2. Nutrient Balance: It helps maintain soil nutrient balance, preventing imbalances caused by excessive single-element fertilization. It also aids in the absorption of essential nutrients like nitrogen (N) and phosphorus (P).

3. Application Methods: It can be used alone or combined with other fertilizers to improve efficiency. Application flexibility allows adjustments based on crop needs and soil conditions.

4. Cost-Effectiveness: While pricier upfront, its long-term benefits justify the cost. Proper use increases crop yield, quality, and reduces losses from pests and diseases.

5. Suitable Crops: It is versatile and especially beneficial for potassium-sensitive crops like citrus, apples, grapes, and others, improving stress resistance and fruit quality.

III. Comprehensive Comparison

1. Target Crops: Choose ammonium bicarbonate for quick nitrogen supplementation; opt for potassium fertilizer to boost disease resistance and fruit quality.

2. Soil Conditions: Match fertilizers to soil pH and nutrient levels. Acidic soils or nutrient-deficient fields may require combined use of both.

3. Fertilization Strategy: Prioritize ammonium bicarbonate for nitrogen needs, then supplement with potassium based on crop growth and soil tests.

4. Application Rates: Determine rates according to crop type, soil fertility, and climate. Excessive use may lead to waste or soil salinization.

5. Environmental Considerations: Prioritize eco-friendly fertilizers to minimize pollution. Balance efficacy with sustainability.

ammonium bicarbonate and potassium fertilizer each have unique strengths. The choice depends on your target crops, soil conditions, and fertilization strategy. By evaluating these factors, you can design a tailored plan to achieve high-quality, high-yield crops.
