Rhizosphere Processes and Management for Improving Nutrient Use Efficiency and Crop Productivity
Molecular Environmental Soil Science at the Interfaces in the Earth’s Critical Zone, 2020Co-Authors: Fusuo Zhang, Jianbo Shen, Jingying Jing, Long Li, Xinping ChenAbstract:High input, high output, low Nutrient resource Use Efficiency and deteriorating environmental problems reflect the typical characteristics of intensive farming system in China. How to achieve synchronously high Nutrient Use Efficiency as well as high crop productivity has become a great challenge in the intensive agriculture of China. In the past two decades, crop production has not proportionally been increased with increasing input of chemical fertilizers, leading to low Nutrient Use Efficiency and increasing environmental problems. Traditional Nutrient management strategy was highly dependent on external chemical fertilizer input, but ignored exploring biological potential of efficient acquisition and Use of soil Nutrient resources by plants intrinsically. Rhizosphere is the key centre of interactions among plants, soils and microorganisms; the chemical and biological processes occurring in the rhizosphere not only determine mobilization and acquisition of soil Nutrients, but also control Nutrient Use Efficiency by crops. The rhizosphere management strategy lays emphasis on maximizing the Efficiency of root and rhizosphere processes in Nutrient acquisition towards high-yield and high-Efficiency sustainable crop production by optimizing Nutrient supply in root zone, regulating root morphological and physiological traits, and manipulating rhizosphere processes and interactions. The strategies of rhizosphere management are proved to be an effective approach to increasing Nutrient Use Efficiency and crop productivity towards sustainable crop production for main crops in China.

maximizing root rhizosphere Efficiency to improve crop productivity and Nutrient Use Efficiency in intensive agriculture of china
Journal of Experimental Botany, 2013Co-Authors: Jianbo Shen, Long Li, Rongfeng Jiang, Chunjian Li, Guohua Mi, Lixing Yuan, Fusuo ZhangAbstract:Root and rhizosphere research has been conducted for many decades, but the underlying strategy of root/rhizosphere processes and management in intensive cropping systems remain largely to be determined. Improved grain production to meet the food demand of an increasing population has been highly dependent on chemical fertilizer input based on the traditionally assumed notion of ‘high input, high output’, which results in overUse of fertilizers but ignores the biological potential of roots or rhizosphere for efficient mobilization and acquisition of soil Nutrients. Root exploration in soil Nutrient resources and root-induced rhizosphere processes plays an important role in controlling Nutrient transformation, efficient Nutrient acquisition and Use, and thus crop productivity. The Efficiency of root/ rhizosphere in terms of improved Nutrient mobilization, acquisition, and Use can be fully exploited by: (1) manipulating root growth (i.e. root development and size, root system architecture, and distribution); (2) regulating rhizosphere processes (i.e. rhizosphere acidification, organic anion and acid phosphatase exudation, localized application of Nutrients, rhizosphere interactions, and Use of efficient crop genotypes); and (3) optimizing root zone management to synchronize root growth and soil Nutrient supply with demand of Nutrients in cropping systems. Experiments have shown that root/rhizosphere management is an effective approach to increase both Nutrient Use Efficiency and crop productivity for sustainable crop production. The objectives of this paper are to summarize the principles of root/ rhizosphere management and provide an overview of some successful case studies on how to exploit the biological potential of root system and rhizosphere processes to improve crop productivity and Nutrient Use Efficiency.

integrated soil crop system management reducing environmental risk while increasing crop productivity and improving Nutrient Use Efficiency in china
Journal of Environmental Quality, 2011Co-Authors: Fusuo Zhang, Xinping Chen, Weifeng Zhang, Rongfeng JiangAbstract:: During the past 47 yr (1961-2007), Chinese cereal production has increased by 3.2-fold, successfully feeding 22% of the global human population with only 9% of the world's arable land, but at high environmental cost and resource consumption. Worse, crop production has been stagnant since 1996 while the population and demand for food continue to rise. New advances for sustainability of agriculture and ecosystem services will be needed during the coming 50 yr to reduce environmental risk while increasing crop productivity and improving Nutrient Use Efficiency. Here, we advocate and develop integrated soil-crop system management (ISSM). In this approach, the key points are (i) to take all possible soil quality improvement measures into consideration, (ii) to integrate the utilization of various Nutrient resources and match Nutrient supply to crop requirements, and (iii) to integrate soil and Nutrient management with high-yielding cultivation systems. Recent field experiments have shed light on how ISSM can lead to significant increases in crop yields while increasing Nutrient Use Efficiency and reducing environmental risk.

rhizosphere processes and management for improving Nutrient Use Efficiency and crop productivity implications for china
Advances in Agronomy, 2010Co-Authors: Fusuo Zhang, Jianbo Shen, Long Li, Junling Zhang, Xinping ChenAbstract:Abstract Rhizosphere dynamics have been widely investigated since the beginning of last century but little attention has been paid to process-based rhizosphere management at an agroecosystem level. High inputs, high outputs, low Nutrient Use Efficiency, and increasing environmental pressure are typical characteristics of intensive farming systems in China. Achievement of high Nutrient Use Efficiency and high crop productivity together is a major challenge for sustainability of Chinese intensive agriculture. Over the last 20 years crop yield has not increased proportionately with increasing fertilizer inputs, leading to low Nutrient Use Efficiency and increasing environmental risk. Traditional Nutrient management is highly dependent on the external fertilizer inputs but ignores exploiting the intrinsic biological potential of rhizosphere processes for efficient mobilization and acquisition of soil Nutrients by crops. Several successful case studies on rhizosphere processes and management have been summarized in this chapter, and the results demonstrate that rhizosphere management provides a unique opportunity to harmonize crop productivity, Nutrient Efficiency, and environmental impact. Rhizosphere management strategies emphasize maximizing the Efficiency of root and rhizosphere processes in Nutrient acquisition and Use by crops rather than solely depending on excessive application of chemical fertilizers. The strategies mainly include manipulating root system, rhizosphere acidification, carboxylate exudation, microbial associations with plants, rhizosphere interactions in terms of intercropping and rotation, localized application of Nutrients, Use of efficient crop genotypes, and synchronizing rhizosphere Nutrient supply with crop demands. Rhizosphere management has been proved to be an effective approach to increasing Nutrient Use Efficiency and crop productivity for sustainable agricultural production.

quantification of yield gap and Nutrient Use Efficiency of irrigated rice in china
Field Crops Research, 2016Co-Authors: Xinpeng Xu, Ping He, Adrian M Johnston, Shicheng Zhao, Wei ZhouAbstract:Abstract Analyzing attainable yield (YA), yield gap (YG), and Nutrient Use Efficiency (NUE) will help develop and inform agricultural policies and strategies to increase grain yield. Data from a total of 2218 on-farm rice experiments were collected between 2000 and 2013 from the main rice production areas of China. Common treatments in each study included the optimum Nutrient management (OPT), farmers' fertilizer practices (FP) and Nutrient omission treatments which were Used to assess YG, yield response to Nutrient (YR), and NUE. This study Used meta-analysis and ANOVA to evaluate differences across the four rice planting seasons (early, middle, late, and single-season rice). The average YA from the OPT was 8.5 t ha −1 , and the yield gap between OPT and FP was 0.6 t ha −1 . The YR to nitrogen (N), phosphorus (P), and potassium (K) averaged 2.4, 0.9, and 1.0 t ha −1 across all sites, respectively. Results using the Pearson' correlation analysis showed significantly negative coefficients for YR to soil Nutrient contents and soil organic matter. The large variations in YR were attributed to differences in climatic conditions and soil indigenous Nutrient supplies. As compared to FP, the average recovery Efficiency (RE) to N, P, and K with OPT increased by 10.1, 5.0 and 8.6 percent across all sites, respectively. In order to narrow the YG and increase NUE, effective soil, plant, Nutrient management measures, advances in knowledge and technologies would be required to sustain higher crop production.

yield gap indigenous Nutrient supply and Nutrient Use Efficiency for maize in china
PLOS ONE, 2015Co-Authors: Xinpeng Xu, Ping He, Adrian M Johnston, Shicheng Zhao, Wei ZhouAbstract:Great achievements have been attained in agricultural production of China, while there are still many difficulties and challenges ahead that call for put more efforts to overcome to guarantee food security and protect environment simultaneously. Analyzing yield gap and Nutrient Use Efficiency will help develop and inform agricultural policies and strategies to increase grain yield. On-farm datasets from 2001 to 2012 with 1,971 field experiments for maize (Zea mays L.) were collected in four maize agro-ecological regions of China, and the optimal management (OPT), farmers’ practice (FP), a series of Nutrient omission treatments were Used to analyze yield gap, Nutrient Use Efficiency and indigenous Nutrient supply by adopting meta-analysis and ANOVA analysis. Across all sites, the average yield gap between OPT and FP was 0.7 t ha-1, the yield response to nitrogen (N), phosphorus (P), and potassium (K) were 1.8, 1.0, and 1.2 t ha-1, respectively. The soil indigenous Nutrient supply of N, P, and K averaged 139.9, 33.7, and 127.5 kg ha-1, respectively. As compared to FP, the average recovery Efficiency (RE) of N, P, and K with OPT increased by percentage point of 12.2, 5.5, and 6.5, respectively. This study indicated that there would be considerable potential to further improve yield and Nutrient Use Efficiency in China, and will help develop and inform agricultural policies and strategies, while some management measures such as soil, plant and Nutrient are necessary and integrate with advanced knowledge and technologies.
