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].
