1、Overview of the vital roles of macro minerals in the human body

Macro minerals, also known as macro elements, are minerals that are required in large amounts in the human body. Macro minerals are part of the biological structure of the human body, play an important role in metabolic processes, and participate in almost all processes that occur in the body.

2、Relationships between the Content of Micro

Many of the micro- and macro-elements (MMEs) required by the body are found in environmental objects in concentrations different from their original concentration that can lead to dangerous animal diseases (“microelementoses”).

3、Microelements vs. Macroelements: What’s the Difference?

Essential for various biological functions, microelements include elements like zinc, copper, and selenium. In contrast, macroelements encompass elements like carbon, hydrogen, and oxygen, which form the foundational blocks of organic molecules.

4、Macronutrient

Macronutrients can be defined as the chemical elements (carbon, hydrogen, nitrogen, oxygen, phosphorus and sulphur) or the classes of chemical compounds (carbohydrates, proteins, fats, water and atmospheric oxygen) that humans consume in the largest quantities (also section 1.1.1).

Dietary macrominerals: Updated review of their role and orchestration

This review is an attempt to illustrate and provide an in-depth discussion on the role of macrominerals in our bodies. Their health benefits, levels in selected food sources, exact required daily intake of each macromineral will be covered, as well as, the risks of having more or less intake.

Difference Between Macro

There are sixteen essential nutrients for plants, and these are divided into categories depending on the amounts plants need of each. The difference between micro and macro minerals, also called elements or nutrients, is the quantity of each needed by various plant species.

Macro

Based on their concentration in various plant tissues required for adequate growth, nine elements are categorized as macronutrients (>0.1% of dry plant tissue) and the rest as micronutrients. The human body cannot biosynthesize these essential elements and acquire them from food.

Macro elements explained

Macro elements include not only the evergreens calcium and magnesium, but also sodium, chloride, potassium and phosphorus. You can find out what this is all about here.

What are macro elements & why are they important to cells?

Macro elements are essential chemical elements required in large quantities for cell growth, development, and physiological functioning, playing fundamental roles in structure, energy, and metabolism.

什么是宏量元素？Macro Elements

其中碳、氢、氧、氮在体内主要以有机物形式存在，其余的如磷、硫、氯、钾、钠、钙、镁等均以无机物形式存在。

The process of selecting macro-elements typically involves the following steps:

1. Define Objectives and Needs: First, clarify the purpose of selecting macro-elements. This may include improving crop yields, enhancing soil quality, or boosting plant health. Understanding these goals helps determine which elements are critical and how to select them effectively.

2. Collect Soil Samples: To assess soil element levels, collect soil samples from farmland or plant root zones. These samples should represent the entire area’s soil conditions to ensure accurate analysis.

3. Conduct Soil Analysis: Use laboratory equipment to analyze soil samples and determine their chemical composition. This includes measuring concentrations of essential elements like nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulfur (S), iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), and boron (B). These tests identify nutrient deficiencies or excesses in the soil.

4. Identify Key Elements: Based on soil analysis results, pinpoint which elements are critical macro-elements. These are vital for plant growth as they participate in numerous biochemical reactions. For example:

   • Nitrogen is key for protein synthesis.
   • Phosphorus supports root development and energy storage/transfer.
   • Potassium regulates water balance and cell wall formation.

5. Develop Fertilization Plan: After identifying key macro-elements, create a fertilization plan tailored to the plant’s specific needs and soil conditions. This includes determining frequency, dosage, and timing. For instance:

   • If soil nitrogen is low, increase nitrogen fertilizer application frequency.
   • If phosphorus is insufficient, adjust phosphorus fertilizer quantities.

6. Implement Fertilization: Apply fertilizers correctly to avoid over- or under-fertilization. Use appropriate fertilizer types, adjust amounts, and follow proper application methods and timing. Avoid chemical reactions with other soil substances that could reduce fertilizer effectiveness.

7. Monitor and Adjust: Regularly monitor soil and plant nutrient status to ensure the fertilization plan’s effectiveness. If imbalances arise (e.g., excess or deficiency of an element), revise the plan or switch fertilizer types/dosages.

8. Education and Training: Ensure farmers understand how to select and use macro-elements properly. Provide guidance on fertilizer types, application methods, precautions, and teach how to tailor plans based on plant needs and soil conditions.

selecting macro-elements requires综合考虑 multiple factors, such as plant requirements, soil conditions, and environmental context. By using scientific methods and technologies, macro-elements can be effectively managed to promote healthy plant growth and improve agricultural productivity.
