Abstract
Given the critical need for more efficient water and nutrient utilization to optimize crop yields, effective strategies in water and nutrient management are essential. The development of a self-irrigation and slow-release fertilizer hydrogel (SISRH) represents a promising approach. SISRH, a hydrogel with hygroscopic polymer chains interpenetrated by a thermoresponsive network, enhances plant growth through controlled yet self-sustained water and nutrient delivery. The hydrogel demonstrates diurnal functionality: it absorbs water vapor at night and releases it during the day due to a phase transition in the polymer, with incorporated calcium chloride (CaCl2) further improving hygroscopic properties and controlled nutrient release. SISRH facilitates a slow-release of nutrients and can achieve ∼40% water savings, significantly reducing the need for frequent irrigation and ensuring robust crop development. The integration of SISRH in soil offers a promising solution to meet the pressing needs of water scarcity and efficient nutrient uptake in modern sustainable agriculture.
期刊介绍:
ACS Materials Letters is a journal that publishes high-quality and urgent papers at the forefront of fundamental and applied research in the field of materials science. It aims to bridge the gap between materials and other disciplines such as chemistry, engineering, and biology. The journal encourages multidisciplinary and innovative research that addresses global challenges. Papers submitted to ACS Materials Letters should clearly demonstrate the need for rapid disclosure of key results. The journal is interested in various areas including the design, synthesis, characterization, and evaluation of emerging materials, understanding the relationships between structure, property, and performance, as well as developing materials for applications in energy, environment, biomedical, electronics, and catalysis. The journal has a 2-year impact factor of 11.4 and is dedicated to publishing transformative materials research with fast processing times. The editors and staff of ACS Materials Letters actively participate in major scientific conferences and engage closely with readers and authors. The journal also maintains an active presence on social media to provide authors with greater visibility.
