Plant Protection Knowledge: Types and Benefits of Novel Fertilizers
I. Amino Acid Fertilizers
1. What are amino acid fertilizers?
Amino acid fertilizers are organic-inorganic complexes formed by using plant-derived amino acids as a base—leveraging their high surface activity and adsorption/retention capabilities—and incorporating essential nutrients for plant growth and development (such as nitrogen, phosphorus, and potassium) through chelation and complexation processes.
2. Benefits of amino acid fertilizers
Amino acids exist in the fertilizer as the fundamental building blocks of proteins, making them easily absorbable by crops; they enhance plant disease resistance and improve crop quality.
They replenish essential amino acids, stimulate and regulate rapid plant growth, strengthen the plant, and promote nutrient uptake. They also boost metabolism, enhance photosynthesis, foster robust root systems, and accelerate growth and reproduction.
II. Humic Acid Fertilizers
1. What are humic acid fertilizers?
Humic acid fertilizers are a type of organic fertilizer. They are produced from raw materials such as peat and lignite using various manufacturing methods to create products rich in humic acid, as well as the nitrogen, phosphorus, potassium, and trace elements required for crop growth and development. They can be applied as base fertilizers or top-dressing, and used for seed soaking, foliar spraying, and root dipping.
2. Benefits of humic acid fertilizers
Improve soil structure and physicochemical properties, thereby enhancing the soil's water and nutrient retention capabilities;
Stimulate crop root growth and development, increase water absorption capacity, and reduce leaf transpiration and water loss;
Enhance crop resilience against adverse environmental conditions and improve the utilization efficiency of water and nutrients.
III. Plant Immune Proteins
To understand this topic, one must first understand the plant immune system. The plant immune system is the result of plants adapting to their environment and co-evolving with other organisms; it mounts a two-tiered immune response against pathogens such as fungi, bacteria, and viruses. The first layer of the immune response involves plant pattern recognition receptors (PRRs) that recognize pathogen-associated molecular patterns (PAMPs); this recognition activates intracellular signaling pathways and induces defense responses to restrict pathogen invasion, a process known as PAMP-triggered immunity (PTI).
The second layer of the immune response arises from the ongoing co-evolution between plants and pathogens: to successfully infect plants, pathogens evolved effector proteins to suppress PTI, while plants evolved R genes to monitor and recognize these effectors, triggering a hypersensitive response (programmed cell death) to limit pathogen invasion—a process known as effector-triggered immunity (ETI). Compared to PTI, the ETI response is more intense and more sustained.
