These benefits are part of amino acids' role as a natural chelator, assisting with nutrient uptake and assimilation to ensure plants are receiving the maximum value and nourishment from soils.
How Amino Acids Are Derived for Agricultural Use
Why Amino Acids Are Essential for Plant Health
What role do amino acids play in plants? They have many important functions that promote plant health, increase stress tolerance, and ultimately increase plant productivity.
- Increase Nutrient Uptake: Amino acids tend to act as natural chelators. They chemically bond to micronutrients (iron, zinc, magnesium), making them more soluble and facilitating their uptake by plant roots.
- Increase Photosynthesis Productivity: Amino acids stimulate chlorophyll production, which is essential for the photosynthesis process. This directly affects the plant's ability to convert sunlight energy into plant growth.
- Help with Enzymes and Hormones: Amino acids are precursors for several plant hormones (i.e. auxins, cytokinins) and alter enzyme functions that regulate many metabolic processes that occur within the plant system.
- Increase Plant Stress Tolerance: Under metabolic stresses induced by drought, salinity, heat or other physiological conditions, amino acids stabilize the cellular structures of plants and reduce oxidative stress and damage. Moreover, during the recovery phase, the increased synthesis of amino acids leads to length of time to recovery.
- Promote Root Development: Some amino acids direct root elongation and branching, increasing the plants ability to acquire water and nutrients from the soil.
- Enhance Flowering and Fruit Set: Amino acids optimally influence the flowering and fruit set stages of plant development by enhancing flower number, viability of pollen, and fruit quantity.
Types of Amino Acids Used in Agriculture
Amino acids can be important in improving crop productivity and improving soil. However, amino acids do not have the same abilities in agricultural settings. Different types of amino acids provide limited value based on plant growth stages and stress conditions. Understanding the different classifications of amino acids is critical for farmers that want to maximize crop growth while utilizing conditions for sustainable agriculture.
Let's look at what amino acids are, amino acid types and how they can enhance agricultural uses.
Essential vs Non-Essential Amino Acids in Plants
Free Amino Acids vs Peptide-Bound Amino Acids
Branched-Chain Amino Acids (BCAAs) and Plant Growth
Branched-Chain Amino Acids (BCAAs) like Leucine, Isoleucine, and Valine are a unique and specific group of essential amino acids known for their unique structure and functionality. Although BCAAs have become a common part of supplements in human nutrition, they also play a key role in agriculture.
When applying fertilizers enriched with BCAAs or BCAA focused biostimulants, farmers will be able to produce crops with improved resilience and get enhanced plant growth in important periods of growth, such as flowering and fruiting.
What Do Amino Acids Do for Crops and Soil?
In the context of agriculture, knowing what amino acids are and their functional role is valuable in improving plant health and soil productivity. Amino acids are more than “nutrients.” They are important components in essential biological activities that govern how a crop grows, responds to stress, and takes up resources from the soil. In this article, we will expand upon what amino acids do for crops and soil production.
Amino Acids as Natural Biostimulants
In agriculture, one of the most critical roles of amino acids are their roles as natural biostimulants. Biostimulants, as opposed to fertilizers, are substances that enhance growth and resiliency, which is done biologically and not nutritionally,
As a biostimulant, amino acids help the plants reach a higher level in terms of optimal performance, which leads to healthier and improved productivity in crops.
Improving Nutrient Uptake and Assimilation
Where do amino acids fit into soils? There are many functions, but one of the most valuable is their facilitation of nutrient uptake and assimilation processes. Amino acids are natural chelating agents, that is, they bind with essential minerals and trace elements in soils, increasing solubility for plant root uptake. The more soluble the minerals and trace elements, the more available they are for plants to absorb into their tissue.
- Chelation of Micronutrients: Amino acids can complex with the minerals and elements in soil that plants need, for example, iron, zinc, and magnesium have complexation examples of soil from amino acids, hence improving bioavailability of the minerals for uptake into root systems.
- Root Stimulation: Certain amino acids, when absorbed by plants, stimulate either root elongation or root branching; both will increase the root surface area for uptake, thus improving nutrient uptake into plant tissue.
- Transport in the Plant: Once nutrients are absorbed, the amino acids will assist in the translocation of those nutrients to various parts of the plant. Amino acids effectively operate to increase the ability of cells to obtain and secure nutrient digestion and transport of nutrients to enhance growth.
As a result, value is created by increased nutrient use efficiency, which not only improves plant vigor but can ultimately reduce fertilizer use for growing food.
Enhancing Photosynthesis and Chlorophyll Production
Photosynthesis is the center of plant life and amino acids play an important role in maximizing photosynthesis. For plants to convert to usable energy from sunlight, plants need sufficient chlorophyll which amino acids are intimately involved in building.
- Improve Chlorophyll Production: Amino acids such as Glutamic acid and Glycine are directly involved in the production of chlorophyll, giving rise to nice green leaves and optimal photosynthesis.
- Enhance CO₂ Assimilation: Enhancing photosynthetic enzymes bring amongst a number of benefits the ability to grab and retain carbon dioxide.
- Enhance Energy Metabolism: Amino acids are involved in the physiological pathways that result in ATP (energy currency) production in plant cells that fuel growth and development.
By enhancing photosynthesis and other related plant processes it ensures that the plant is producing more energy and as a consequence more biomass and fruit set resulting in increases in yield.
