The global population greatly depends on rice as a staple food, contributing significantly to global warming and agricultural greenhouse gas (GHG) emissions. Agricultural soils play a crucial role in the release and uptake of essential GHGs, including methane (CH₄), nitrous oxide (N₂O), and carbon dioxide (CO₂), serving as both sources and sinks within the agricultural ecosystem. Notably, rice fields alone account for approximately 30% and 11% of global CH₄ and N₂O emissions from agricultural activities, respectively. As the demand for rice is expected to rise in the future, it becomes increasingly critical to address GHG emissions and minimise the detrimental environmental effects associated with rice production. This review provides a comprehensive synthesis of the available data regarding the influence of different crop management practices on GHG emissions in rice fields. We recognise the substantial potential for reducing GHG emissions through modifications in traditional crop management systems. Our analysis evaluates various options, such as adjustments in cropping practices, regulation of organic and fertiliser inputs, management of tillage techniques and irrigation strategies, and the selection of suitable cultivars, all of which can contribute to GHG emission reduction. It is crucial to consider that changes in management practices may have simultaneous and sometimes contradictory effects on different gases through various mechanisms. Therefore, our comprehensive evaluation aims to assess the potential global warming impact of each approach, considering the magnitude of their effects on all gases. This assessment seeks to identify suitable crop management practices that effectively reduce GHG emissions in rice cultivation while considering the overall environmental impact.</p>","PeriodicalId":100834,"journal":{"name":"Journal of Sustainable Agriculture and Environment","volume":"3 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/sae2.70012","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142524763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The lignin content of palm fronds ranges from 17% to 20%, while the maximum lignin content in ruminant feed is 7%. Processing processes such as pretreatment are needed to reduce the lignocellulose content. Pretreatment can be done physically, chemically, biologically or in combination with other methods. Physical pretreatment aims to reduce the size of lignocellulose, chemical pretreatment seeks to break the crystallinity structure of lignocellulose with chemical solutions such as acids or alkalis, and biological pretreatment degrades the structure of lignocellulose with the help of enzymes produced by microbes. The protein content of palm fronds also does not meet the feed standard, which is only 5%, while according to Indonesian national standards, ruminant feed, especially cattle, must have a minimum protein content of 14%. Therefore, it is necessary to improve the nutritional quality of palm fronds through fermentation methods. The selection of the right microbes is the main factor in the success of increasing nutrition. The SSF fermentation method is frequently used in feed manufacturing.

With a market projection of $5.02 billion by 2030, biofertilizers are gaining momentum as a supplement and, in some cases, as an alternative to chemical fertilizers. Biofertilizers can improve the nutritional supply to the plant and simultaneously can improve soil health, reduce greenhouse emissions, and hence directly contribute towards environmental sustainability. Plant growth-promoting microbes (PGPMs) are particularly receiving significant attention as biofertilizers. They are widely known for their ability to improve plant growth via increasing nutrient availability and use efficiency. However, except for a few successful cases, the commercialization of PGPM-based inoculants is still limited, mainly due to lack of field efficacy and consistency. Lack of effective formulation technologies that keep microbial inoculants viable during storage, transport and field application is considered one of the key factors that drive inconsistent efficacy of microbial biofertilizers. In this review, we identify current challenges associated with the application and formulation of microbial inoculants. We propose future paths, including advancement in formulation technologies that are potentially efficient, eco-friendly and cost-effective. We argue that to enhance the global adoption of biofertilizers, new innovations based on transdisciplinary approaches are indispensable.
