“…These practices effectively curtailed surface ammonia volatilization ( Mutters et al., 2010 ; Gaihre et al., 2023 ). Previous studies show the NUE improvement that involves the application of N fertilizers in multiple split doses ( Li et al., 2018 ; Phongchanmixay et al., 2019 ; Jiang-ming, 2023 ). However, many split fertilizations also increase farmer’s labour output and crop damage, reducing net benefits.…”

IntroductionRice heavily relies on nitrogen fertilizers, posing environmental, resource, and geopolitical challenges. This study explores sustainable alternatives like animal manure and remote sensing for resource-efficient rice cultivation. It aims to assess the long-term impact of organic fertilization and remote sensing monitoring on agronomic traits, yield, and nutrition.MethodsA six-year experiment in rice fields evaluated fertilization strategies, including pig slurry (PS) and chicken manure (CM) with mineral fertilizers (MIN), MIN-only, and zero-fertilization. Traits, yield, spectral responses, and nutrient content were measured. Sentinel-2 remote sensing tracked crop development.ResultsCost-effective organic fertilizers (PS and CM) caused a 13% and 15% yield reduction but still doubled zero-fertilization yield. PS reduced nitrogen leaching. Heavy metals in rice grains were present at safe amounts. Organic-fertilized crops showed nitrogen deficiency at the late vegetative stages, affecting yield. Sentinel-2 detected nutrient deficiencies through NDVI.DiscussionOrganic fertilizers, especially PS, reduce nitrogen loss, benefiting the environment. However, they come with yield trade-offs and nutrient management challenges that can be managed and balanced with reduced additional mineral applications. Sentinel-2 remote sensing helps manage nutrient deficiencies. In summary, this research favors cost-effective organic fertilizers with improved nutrient management for sustainable rice production.

“…According to [27], a review paper on zinc's role in rice production systems, zinc fertilizers can increase crop output by as much as 33%. Zinc is crucial for plant development because it helps make chlorophyll, aids in leaf and stem growth, and is involved in the creation of plant hormones.Zinc availability is also influenced by soil organic matter content, as organic matter can complex with zinc and impede its uptake by plants [27,19].Other nutrients, such as phosphorus, nitrogen, and organic matter, can also influence zinc availability in paddy soils [29,35,33].Proper nutrient management, including balanced fertilization and organic amendments, can improve zinc availability and uptake by paddy crops [29,22,36].…”

A systematic literature review emphasizes the significance of nutrient management in paddy crop production. It covers the crucial nutrients and their deficiencies that can substantially reduce crop growth, yield, and quality. Nutrient deficiency management challenges and limitations vary across different growth stages and are influenced by factors such as soil nutrient availability, plant genotype, and environmental conditions. Effective nutrient management strategies, such as fertilization, foliar spraying, and breeding for nutrient-use efficiency, can help mitigate these challenges and improve crop growth and yield. By applying fertilizers at the appropriate time and amount, proper nutrient management practices can enhance rice growth and yield. The review offers insights into the challenges and opportunities for improving nutrient management in paddy crop production and identifies emerging technologies to overcome these challenges. The study also contributes to the development of advanced computing technologies to predict nutrient deficiencies in various stages of paddy growth.

The substitution of microbial fertilizer for chemical fertilizer can not only improve soil fertility but also effectively enhance rice quality. To investigate the effect of different amounts of combined application of chemical fertilizer and microbial fertilizer on the amylose content of rice, this study adopts theoretical calculations to compare the preprocessed Raman spectroscopy information of rice with reduced fertilization and establishes a recognition model for the amylose content of rice, which is used to detect the amylose content in rice. Based on the amylose spectral values measured by Raman spectroscopy and the known starch structure and functional groups, the Raman peaks are mainly distributed in the range of 400 cm − 1 to 1400 cm − 1 . The Raman characteristic peaks at 483 cm − 1 , 869 cm − 1 , 933 cm − 1 , 1082 cm − 1 , 1126 cm − 1 , 1335 cm − 1 , 1385 cm − 1 , and 1455 cm − 1 exhibit strong vibration modes, which are consistent with its main nutrient component of amylose. By comparing the measured amylose content in the regions treated with microbial fertilizer combined with different amounts of reduced fertilization and the spectral intensity values of amylose measured by Raman spectroscopy, the results show that the treatment of combining conventional amounts of microbial fertilizer with different amounts of reduced chemical fertilizer exhibits a decreasing trend in the amylose content of rice.
