1、Fertilization with Phosphorus, Potassium, and Other Nutrients

Phosphorus and potassium are the two primary macronutrients nonmobile in the soil (see Chap. 2). When applied as fertilizer, both nutrients are quickly fixed in the soil solid fraction, mainly by adsorption or precipitation.

2、Functions of Nitrogen, Phosphorus and Potassium in Energy Status and

Nitrogen (N), phosphorus (P) and potassium (K) are important essential nutrients for plant growth and development, but their functions in energy status remains unclear.

3、Fertilizer: Definition, Types, Advantages, Disadvantages, Uses

These fertilizers include nitrogen, potassium, and phosphorus, which are crucial elements needed by plants. They also increase the soil’s fertility and its ability to retain water. Urea, anhydrous ammonia, super phosphate superphosphate, potassium sulfate, etc. are some examples of fertilizers.

4、Liquid Fertilizers Containing Phosphorus and Potassium: Types and Areas

Liquid fertilizers containing phosphorus and potassium can be used on many different types of plants, including field crops, garden crops, fruit trees and vegetables.

5、Understanding the Big Three: Nitrogen, Phosphorus, and Potassium

Understanding the “Big Three” nutrients – Nitrogen, Phosphorus, and Potassium (NPK) – is essential for effective fertilizer management in agriculture. These primary macronutrients play a crucial role in plant growth and development. Here’s a deeper look at each of them:

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.

Fertilizer with Potassium and Phosphorus

For best plant growth, fertilizers should be used to add nitrogen, phosphorus, and potassium, which are the nutrients that are most likely to be lacking. The best method for assessing nutrient availability in your garden is to do a soil test.

1. Types of Phosphorus-Containing Fertilizers

a. Ordinary Superphosphate

• Definition: A common phosphate fertilizer with calcium dihydrogen phosphate (Ca(H₂PO₄)₂) as its main component.
• Form: Powder or granular.
• Use: Enhances soil phosphorus content to promote plant growth, especially in phosphorus-deficient soils.

b. Ammonium Phosphate

• Definition: A compound fertilizer formed by the reaction of phosphoric acid and ammonia.
• Form: White crystals or powder.
• Use: Provides both nitrogen and phosphorus, suitable for plants requiring these nutrients.

c. Monoammonium Phosphate

• Definition: A compound fertilizer produced by reacting phosphoric acid with ammonia gas.
• Form: White crystals or powder.
• Use: Primarily used to increase soil phosphorus levels.

2. Types of Potassium-Containing Fertilizers

a. Potassium Sulfate

• Definition: A potash salt extracted from seawater.
• Form: White crystals or powder.
• Use: Supplements potassium for healthy plant growth.

b. Potassium Chloride

• Definition: A potash salt obtained through chlorination of seawater.
• Form: White crystals or powder.
• Use: Supplements potassium for healthy plant growth.

c. Potassium Nitrate

• Definition: A compound fertilizer formed by reacting nitric acid with potash.
• Form: White crystals or powder.
• Use: Supplements potassium for healthy plant growth.

3. Functions of Phosphorus-Potassium Fertilizers

a. Promoting Plant Growth

Phosphorus and potassium are essential nutrients for plants. Phosphorus supports root development and nutrient uptake, while potassium improves water and nutrient use efficiency, collectively enhancing overall plant growth.

b. Enhancing Disease Resistance

Adequate phosphorus and potassium strengthen a plant’s immune system. Phosphorus activates defensive mechanisms, while potassium reinforces cell walls, reducing susceptibility to pathogens.

c. Improving Crop Quality

These fertilizers enhance traits like fruit sweetness and flavor. Phosphorus aids sugar synthesis and transport, while potassium boosts sugar utilization, elevating crop quality.

d. Increasing Crop Yield

Proper phosphorus and potassium levels significantly boost yields by accelerating growth, improving photosynthesis, and supporting seed germination and seedling establishment.

phosphorus-potassium fertilizers play critical roles in agriculture by promoting growth, enhancing disease resistance, improving crop quality, and increasing yields. Their rational application is vital for healthy crop production and optimized agricultural productivity.
