“…This is largely related to NO 3 --N and NH 4 + -N dis- Chiplot tribution in the root zone (Chen et al 2023). Also, optimising fertilisation depth can maximise the capacity of maize roots to absorb nutrients by enhancing soil chemical and biochemical characteristics in the root zone (Wu et al 2024). In addition, studies have shown that suitable fertilisation depth could indirectly reduce soil bulk density, increase soil porosity and enhance soil agglomeration by promoting soil organic carbon and microbial community (Nyamangara et al 2001, Su et al 2015.…”

In conventional maize planting systems, farmers' fertiliser is artificially urea surface broadcasting method, which can lead to uneven fertiliser placement accompanied by crop lodging, especially in the case of excessive nitrogen application , 2023. Controlled-release urea is widely used in rice, wheat and maize (Qiang et al. 2020, Zhu et al. 2020, Lan et al. 2024. The controlled-release urea placement depths significantly impact nitrogen use efficiency, which greatly improves crop yield and reduces nitrogen loss (Ke et al. 2018). Previous reports have shown deep controlled-release urea placement (12 cm) could reduce the nitrogen addition by 20% and improve nitrogen use efficiency, resulting in yield benefits (Qiang et al. 2022). Chen et al. (2023 and Wu et al. (2022) found that deep nitrogen fertilisation can improve crop yield by promoting root

“…Therefore, compared with varieties with deeper root growth angles and larger lateral root lengths, more fertilizers and water should be used in their cultivation. Measures such as deep fertilization (Wu et al 2022, Chen et al 2024) and exogenous application of plant hormones (Kosakivska et al 2022) can be taken to promote root elongation and lateral root development to enhance the absorption and utilization of water and nutrient. In summary, this study once again demonstrates that shovelomics is beneficial for effectively screening and selecting plant genotypes with contrasting root traits, and optimizing nutrient and water management based on root types.…”

Root phenes are associated with the absorptive efficiency of water and fertilizers. However, there are few reports on the genetic variation and stability of peanut (Arachis hypogaea L.) root architecture under different environments. In this study, the diversity, variance and stability of root phenes of 89 peanut varieties were investigated with shovelomics (high throughput phenotyping of root system architecture) for two years in both field and laboratory experiments. The root phenes of these peanut genotypes presented rich diversity; for example, the value of total root length (TRL) ranged from 347.84 cm to 1013.80 cm in the field in 2018, and from 55.14 cm to 206.22 cm in the laboratory tests. The root phenes of different genotypes varied differently; for example, the coefficient of variation (CV) of TRL ranged from 24.0 to 83.5 across the two‐year field test. Field and laboratory evaluations were highly correlated, especially on lateral root density (LRD) and root angle (RA), and the quadrant graph analysis of LRD and RA implied that 69.7% of the roots belong to the same type. These not only further reflect root phenes stability through different environment but also demonstrate that some root phenes identified at early stage can indicate their status at later growth stage. In addition, root phenes showed a strong correlation with shoot growth, especially root dry weight (RDW), TRL and（nodule number）NN. Thus, laboratory tests in combination with field shovelomics can efficiently screen and select genotypes with contrasting root phenes to optimize water and nutrient management.

“…Moreover, fertilization methods also affect the use of water and fertilizer by crops. Compared with fertilization by broadcasting, shallow or deep band fertilization can improve the crop yield, and deep fertilizer placement is better [ 71 ]. Li et al found that a nitrogen fertilizer deeply applied under the film-mulched band could reduce the ammonia volatilization loss and prevented nitrate leaching [ 72 ].…”

Lucid waters and lush mountains are invaluable assets. Resource-saving and environmentally friendly industrial structures, production, and living modes are pursued continuously for sustainable ecological development. According to the Second National Pollution-Source Survey, agricultural non-point pollution is still the most important source of the current water pollution. In order to improve the water environment and control the pollution, the meaning and content of the eco-agricultural industrial chain was introduced. Based on this conception, the eco-agricultural industrial chain, integrating a whole circular system with different sessions of crop farming, animal breeding, agricultural product processing, and rural living, was innovatively put forward to control the agricultural non-point pollution and protect the water environment systematically for the first time in this paper. The sustainable development was realized at a large scale from the reduction and harmlessness at the source, resource utilization in the process, and ecological restoration in the end. Core techniques were innovated based on the integration of agricultural industries to achieve the high-quality and green development of agriculture. The system included ecological breeding technologies, ecological cultivation technologies, as well as rural sewage treatment and recycling technologies, in the principle of reduce, reuse, and resource. Based on this, the agricultural production changed from the traditional mode of “resources–products–wastes” to the circulation pattern of “resources–products–renewable resources–products”. Thus, the final aim could be achieved to realize the material’s multilevel use and energy conversion in the system. The eco-agricultural industrial chain technology was proven to be efficient to achieve both the good control of agricultural non-point pollution and an effective improvement in the water quality.
