Abstract

Global crop production is significantly reduced by rapid changes in the climate, either by natural or manmade activities. The frequent application of various fertilizers, has resulted in soil pollution, which is further exacerbated by water scarcity. The indiscriminate use of chemical fertilizers has led to devastating consequences such as reduction of soil fertility, environmental contamination, increased insect resistance, destroyed biodiversity, and ultimately resulted in heavy economic losses. Another approach being investigated and explored is the use of biofertilizers, which is a better supplement to improve crop yields without harming the environment. However, a significant challenge lies in the fact that plants cannot utilize whole biofertilizer intact, as much of the portion remained unabsorbed or became part of the soil instead of reaching the targeted site. This problem can be solved by nanotechnology; nano-biofertilizers increase tolerance against abiotic stresses. They improve plant morphology, biochemistry and yield, as well as soil composition. Thus, in comparison to conventional chemical fertilizers, nano-biofertilizer produce eco-friendly, sustainable and longer-lasting outcomes. This paper discusses a review of biofertilizer formulations based on nanotechnology for sustainable agriculture development. The invention and application of nano-biofertilizer on various plant species is highlighted in this paper, along with how it improves the growth and development of plants.

纳米生物肥料是改良非生物胁迫下作物的一种生态友好型可持续方法
由于自然或人为活动造成的气候急剧变化,全球作物产量大幅下降。频繁施用各种化肥导致土壤污染,而缺水又进一步加剧了污染。化肥的滥用导致了破坏性后果,如土壤肥力下降、环境污染、昆虫抗药性增强、生物多样性遭到破坏,最终造成了严重的经济损失。目前正在研究和探索的另一种方法是使用生物肥料,这是提高作物产量而又不损害环境的更好补充。然而,一个重大挑战在于植物无法完整地利用全部生物肥料,因为大部分生物肥料仍未被吸收或成为土壤的一部分,而不是到达目标地点。纳米技术可以解决这个问题;纳米生物肥料可以提高对非生物性压力的耐受性。它们能改善植物形态、生物化学和产量,以及土壤成分。因此,与传统化学肥料相比,纳米生物肥料能产生生态友好、可持续和更持久的效果。本文综述了基于纳米技术的生物肥料配方,以促进农业可持续发展。本文重点介绍了纳米生物肥料的发明和在各种植物上的应用,以及它如何改善植物的生长和发育。
