Core Insights - The collaboration between Tomsk Polytechnic University and Guangdong University of Technology has led to the development of a novel nano-fertilizer based on natural mineral kaolinite, which features controlled nutrient release properties that can accelerate plant growth and increase yield [1][2]. Group 1: Fertilizer Development - The new nano-fertilizer addresses the common issues of nutrient loss and low utilization rates associated with traditional fertilizers, providing essential trace elements for plants [1]. - The researchers utilized kaolinite's nanotube structure as a carrier, incorporating copper, boron, and iodine as active ingredients to create this innovative fertilizer [1]. Group 2: Application and Effectiveness - The "micro-injection" effect of the kaolinite nanotubes allows for efficient nutrient delivery by penetrating plant tissues and releasing beneficial components during application [1]. - Experimental results indicated a 34% increase in the growth of microgreens (specifically, sesame greens) when treated with the kaolinite-based nano-fertilizer, showcasing its significant potential for enhancing plant yield [1]. Group 3: Research Findings - Modifications to the kaolinite nanotubes resulted in a notable change in morphology, with the outer diameter increasing from 100 nanometers to 185 nanometers, confirming the incorporation of active substances into the kaolinite's pore structures [2]. - Tests demonstrated that the nano-fertilizer evenly distributed on plant leaves and exhibited good adhesion stability, indicating its potential for foliar application [2]. - Ongoing research is focused on testing the fertilizer's effectiveness on barley crops under field conditions [2].

Overview - Long-term use of chemical fertilizers has led to soil compaction and salinization, making straw fertilizer a green and eco-friendly organic fertilizer that improves soil structure, enhances soil fertility, and promotes crop growth, meeting the needs of green and organic agriculture [1][13] - The market demand for straw fertilizer has been increasing, driven by heightened consumer awareness of food safety and ecological environment, leading to a rapid rise in China's straw fertilizer market, with a projected demand of 22.1 million tons and a market size of 16.442 billion yuan in 2024, with an average product price of approximately 744 yuan per ton [1][13] Market Policies - A series of policies have been issued in China to promote the resource utilization of straw, providing a favorable policy environment for the development of the straw fertilizer industry, including the "National Agricultural Green Development Pilot Zone Implementation Plan" and "Opinions on Accelerating the Construction of a Waste Recycling System" [4][6] Industry Chain - The straw fertilizer industry chain consists of upstream (crop straw collection and transportation, agricultural machinery), midstream (production and processing of straw fertilizer), and downstream (application in various crops such as rice, wheat, corn, vegetables, and fruits) [7][9] Upstream Resources - In 2024, China's theoretical straw resource amount is estimated to reach 994 million tons, with rice straw at 222 million tons, wheat straw at 175 million tons, and corn stalks at 341 million tons, providing ample raw material support for the straw fertilizer industry [9] Downstream Demand - The grain crop sector, including cereals, tubers, and legumes, accounts for over 50% of the downstream demand for straw fertilizer, with the total grain planting area in China projected to reach 11.932 million hectares in 2024, indicating significant growth potential for the straw fertilizer industry [11] Competitive Landscape - The straw fertilizer industry in China is characterized by a low market concentration with many small-scale enterprises, including key players such as Anhui Ruichi Land Biological Technology Co., Ltd., Straw Holdings Group Co., Ltd., and others, primarily located in Beijing, Hebei, and Shandong [15][17] Development Trends - The variety of straw fertilizer products is expected to increase, with companies focusing on R&D for new types of fertilizers, including bio-organic fertilizers with special microorganisms and compound fertilizers with trace elements, while optimizing the entire industry chain from raw material collection to production and sales [21]

Core Viewpoint - The article highlights the promotion of scientific fertilization techniques in the corn industry in Yangshan, Guangdong, emphasizing the importance of soil testing and tailored fertilization for sustainable agricultural development [1][10]. Group 1: Event Overview - A live training event focused on scientific fertilization techniques for corn was held in Yangshan, attracting over 70,000 online viewers [3][5]. - The event was organized by various agricultural institutions and aimed to enhance the quality and coverage of scientific fertilization training [4][8]. Group 2: Agricultural Development Initiatives - Yangshan has over 90,000 acres dedicated to corn cultivation and is part of a broader initiative to develop five major agricultural industries in Qingyuan City [9][10]. - The county has been recognized as a demonstration area for reducing chemical fertilizer use while increasing efficiency [11]. Group 3: Fertilization Techniques - The application of soil testing and tailored fertilization has reached over 1.05 million acres, with specific fertilizer application covering 615,000 acres [13][14]. - The fertilization process is divided into three stages: base fertilization (10% of total), jointing stage (50-60%), and tasseling stage (30-40%), with the latter including micronutrients [19][20][22]. Group 4: Practical Applications and Feedback - Demonstration fields are used for experimental comparisons of different fertilizers, providing local farmers with scientific references for their practices [23][25]. - Farmers have reported positive outcomes from using long-lasting fertilizers, which reduce labor input and improve crop health [29][32].
