Potassium plays an important role in crop physiology, hence, it is recommended as a basal macronutrient. It is highly mobile and leaches quickly to become phyto-unavailable; hence, for the first time, a nano material-assisted coating on muriate of potash (KCl), which serves 80% of potassium fertilizer needs, was attempted. A rotary drum coater was used to coat binary carbohydrates, namely, chitosan and lignin, with anionic clay as a reinforcement agent that favors stable coordination bonds. Thus, the coated fertilizer fulfills industrial requirements such as storage stability and resistance to abrasion. Finally, the coated fertilizer was able to improve wheat production efficiency to ∼17%. In the process of release function, clay stake extend the diffusion time while, recalcitrant lignin gives cation exchange capacity assisted nutrient feeding as well as laccase triggered slow release. The coating matrix improved the stability of lignin against laccase significantly to complement the slow release and efficiency.

仿土壤生态友好肥料门：纳米粘土增强二元碳水化合物可提高作物效率

钾在作物生理学中发挥着重要作用，因此，建议将其作为基础大量营养素。它具有高度流动性，并且很快就会被浸出而变得无法被植物利用；因此，首次尝试了纳米材料辅助的氯化钾 (KCl) 涂层，可满足 80% 的钾肥需求。使用转鼓涂布机涂布二元碳水化合物，即壳聚糖和木质素，并用阴离子粘土作为有利于稳定配位键的增强剂。因此，包膜肥料满足工业要求，例如储存稳定性和耐磨性。最终，包膜肥料能够将小麦生产效率提高至~17%。在释放功能过程中，粘土桩延长了扩散时间，而难降解的木质素提供了阳离子交换能力，辅助养分供给以及漆酶引发的缓慢释放。包衣基质显着提高了木质素对漆酶的稳定性，以补充其缓慢释放和效率。
