CATIONIC AMINO ACID TRANSPORTER1 (CsCAT1) was identified as a key regulator of theanine distribution in tea plants. CsCAT1 transports theanine and affects its allocation between stems and leaves. Repressing CsCAT1 increases theanine content in young leaves, making it a potential target for improving tea quality.

Conservation Agriculture, key to Climate-Resilient Farming Systems

https://jeas.agropublishers.com/2023/01/conservation-agriculture-key-to-climate-resilient-farming-systems/

Conservation agriculture is considered to be climate-smart agriculture. It helps farmers sustain, boost yields, increase profits, reverse land degradation, protect the environment, and respond to climate change. Therefore, conservation agriculture has the potential to ensure food security for rapidly increasing population under changing climatic conditions.

Conservation agriculture practices provide valuable support to ecological services through diversified and interrelated pathways.

Soil Health: Key to Achieving the Sustainable Development Goals

Soil Science: https://jeas.agropublishers.com/?s=Soil+Science

Soil is the unconsolidated cover of the earth, made up of mineral and organic components, containing water and air, and capable of supporting plant growth. Globally around 95% of human food is directly or indirectly produced on soils.

Soil is an extremely complex but dynamic ecosystem and a highly valuable resource. It consists of minerals, organic matter (OM), living organisms, water, and air are its components. Soil maintains an unceasing flow of matter and energy within and with the environment through different chemical, physical and biological processes

Soil Profile: A soil profile is a vertical cross-section of soil, showcasing its different layers or horizons.

Soil Science MCQs https://agropublishers.com/2024/10/05/mcqs-soil-science/

These layers, also known as soil horizons, are distinct due to variations in their composition, structure, and appearance.

Key Components of a Soil Profile
Soil Horizons: The primary feature of a soil profile is the presence of distinct layers, or horizons, each with unique characteristics.

Parent Material: At the base of the profile lies the parent material, the bedrock or weathered rock from which the soil is formed.

Regolith: This includes all the weathered material above the parent rock, encompassing the soil profile.

Types of Soil Horizons:
O Horizon: This is the uppermost layer, rich in organic matter and often containing partially decomposed plant and animal remains.
Construction: Geotechnical engineers rely on soil profile analysis to assess the suitability of a site for building foundations and to predict potential.
A Horizon (Topsoil): Characterized by a dark color due to organic matter, this layer is where most plant roots grow and where biological activity is high.

B Horizon (Subsoil): Generally lighter in color and more clay-rich than the A horizon, it often has less biological activity but holds more moisture.

C Horizon: This is the layer of partially weathered bedrock, the parent material from which the soil is derived.

R Horizon (Bedrock): This is the solid, unweathered bedrock at the base of the soil profile.

Importance of Soil Profiles
Agriculture: The soil profile influences the availability of nutrients, water holding capacity, and root growth, all crucial for plant growth.

Forestry: Soil profiles are essential for understanding forest ecosystems and the suitability of different forest types to specific soil conditions.

Construction: Geotechnical engineers rely on soil profile analysis to assess the suitability of a site for building foundations and to predict potential.

Trichoderma & Pseudomonas: Dual Bio-Control for Healthy Crops

Agriculture MCQs for professional test preparation: https://jeas.agropublishers.com/free-online-mcq-test/

Trichoderma, a beneficial fungus, and Pseudomonas, a beneficial bacterium, are powerful allies in sustainable agriculture. When used together, they act as eco-friendly bio-control agents that suppress harmful plant pathogens, enhance soil health, and promote higher crop productivity—without the risks of chemical residues.

✅ Benefits
1. Disease Control: Suppress soil-borne fungal diseases like root rot, damping-off, and wilt. Protects against both fungal and bacterial infections.
2. Soil Health: Enhance soil fertility and nutrient availability (e.g., phosphorus). Improve soil structure and permeability. Support stronger and deeper root development.
3. Plant Immunity: Trigger systemic resistance in plants, making them more resilient to stress and pathogens.
4. Organic Farming: 100% natural, residue-free, and safe for organic agriculture.

---
🔬 How They Work
Trichoderma (Fungus):
Antagonism: Competes with pathogens for space and nutrients.
Parasitism: Directly attacks and degrades fungal cell walls.
Defense Induction: Activates plant immune responses.

Pseudomonas (Bacterium):
Antibiotics & Enzymes: Inhibit pathogen growth and break down fungal walls.
Siderophores: Trap iron, starving pathogens of essential nutrients.
Nutrient Solubilization: Makes phosphorus and other nutrients more available to
✨ This combination is a powerful, eco-friendly, and cost-effective solution for sustainable farming — leading to healthier soil, stronger plants, and higher yields.

1. Igneous Rocks: Formed from the cooling and solidification of molten rock (magma or lava).
Subdivisions:
Intrusive: Formed when magma cools and solidifies underground, resulting in larger crystals (e.g., Granite, Gabbro).
Extrusive: Formed when lava cools and solidifies on the Earth's surface, often leading to smaller crystals or a glassy texture (e.g., Basalt, Obsidian).

2. Sedimentary Rocks: Formed from the accumulation and compaction of sediments (fragments of pre-existing rocks, minerals, or organic matter). They are often layered and can contain fossils. Examples: Sandstone, Shale, Limestone.

There are three main types, i.e., Igneous, Sedimentary, and Metamorphic. These types are further subdivided based on their characteristics. exhibit foliation (layered appearance) or be non-foliated. Examples: Marble (from Limestone), Slate (from Shale), Gneiss (from Granite).
