1、CHAPTER: 7 SECONDARY AND MICRONUTRIEN T FERTILIZERS

The secondary plant nutrients are Ca, Mg and S. Out of these, three nutrients, Ca and Mg are added indirectly in soil through fertilizes and soil amendments. Soil contains Ca and Mg as...

2、Chapter 5 Secondary and Micronutrients

Chapter 5 Secondary and Micronutrients Although a major portion of this text is devoted to the discussion of the three major fertilizer elements, nitrogen, phosphorus, and potassium, there are nine other essential plant food nutrients which are considered as fertilize.

3、Nutrient Science

They’re divided into three categories: primary macronutrients, secondary macronutrients and micronutrients. These are the major building blocks of all fertilizers and make up the bulk of all fertilizer produced. It may be number seven on the periodic table, but as a primary macronutrient, nitrogen is number one.

4、Plant nutrition and soil fertility: physiological and molecular avenues

Virtually all metabolic and cellular functions, like primary and secondary metabolism, energy metabolism, cell protection, gene regulation, hormone perception, signal transduction, and reproduction involve micronutrients (Hänsch & Mendel, 2009).

Secondary Nutrients and Micronutrients

Increased knowledge about secondary nutrients and micronutrients, including plant requirements, nutrient sources, and methods of application, has resulted in their increased use.

The grades of fertilizers have been increased to decrease handling and shipping costs, with ·the result that there is less room for the secondary and micronutri ents that formerly were included incidentally because they were presen

Section 4: Fertilizers

Fertilizers provide plants with the nutrients necessary for healthy growth. Apart from the macronutrients N, P, K, Ca, Mg, and S there is a known suite of micronutrients (Fe, Mn, B, Cu, Cl, Zn and Mo) that play important roles in the plant’s metabolism.

Secondary and micronutrient fertilizers contain a variety of essential trace elements critical for plant growth and development. These elements include iron (Fe), zinc (Zn), manganese (Mn), copper (Cu), boron (B), molybdenum (Mo), chlorine (Cl), calcium (Ca), magnesium (Mg), and sulfur (S). Below is a detailed introduction to these elements:

1. Iron (Fe): Iron is a vital micronutrient for plants, playing a key role in photosynthesis, respiration, and energy metabolism. Iron deficiency leads to yellowing leaves, stunted growth, and severe cases may cause plant death. Iron fertilizers enhance iron content in plants, promoting healthy growth.

2. Zinc (Zn): Zinc is essential for root development, pollen formation, protein synthesis, and photosynthesis. Deficiency results in leaf tip necrosis, fruit drop, and slow growth. Zinc fertilizers boost zinc levels, supporting plant vitality.

3. Manganese (Mn): Manganese is crucial for the growth of roots, stems, leaves, flowers, and fruits. Its deficiency disrupts chlorophyll production and photosynthesis. Manganese fertilizers improve manganese uptake, aiding overall development.

4. Copper (Cu): Copper supports root growth, chlorophyll synthesis, protein production, and photosynthesis. A lack of copper causes interveinal chlorosis and may kill plants. Copper fertilizers increase copper availability, enhancing growth.

5. Boron (B): Boron is necessary for root and chlorophyll development, protein synthesis, and photosynthesis. Deficiency leads to distorted leaves, abnormal fruits, and slow growth. Boron fertilizers alleviate these issues by replenishing boron.

6. Molybdenum (Mo): Molybdenum aids in root growth, chlorophyll synthesis, nitrogen metabolism, and photosynthesis. Its deficiency causes leaf and fruit malformations. Molybdenum fertilizers correct deficiencies, promoting healthy growth.

7. Chlorine (Cl): Chlorine supports root development, chlorophyll production, and photosynthesis. Deficiency results in stunted growth and畸形 tissues. Chlorine fertilizers ensure adequate Cl levels for optimal development.

8. Calcium (Ca): Calcium is vital for cell wall structure, root growth, and nutrient uptake. Calcium deficiency causes leaf and fruit deformities. Calcium fertilizers prevent these issues by maintaining Ca balance.

9. Magnesium (Mg): Magnesium is central to chlorophyll synthesis and photosynthesis. Deficiency leads to yellowed leaves and poor fruiting. Magnesium fertilizers restore Mg levels, improving plant health.

10. Sulfur (S): Sulfur contributes to protein and vitamin synthesis, root growth, and photosynthesis. Deficiency causes leaf discoloration and slow growth. Sulfur fertilizers mitigate these effects by boosting S availability.

secondary and micronutrient fertilizers supply essential elements that are indispensable for plant growth. Proper use of these fertilizers enhances crop yield, quality, and sustainable agricultural practices.
