“…The frequency of irrigation was 45 times, accounting for 5.10%. Although the application of watersaving irrigation equipment alleviates NPS pollution caused by irrigation, it is still a difficult problem to effectively control NPS pollution caused by the recession of paddy field [22,53].…”

Background With effective control of point source pollution, non-point source (NPS) pollution has been widely concerned as the primary reason for the improvement of global water environmental quality. Some bibliometric analysis related to NPS pollution has been carried out before the mid-2010s. Analyzing the research status and hot issues of NPS pollution in the past decade is important for guiding the control and management of NPS pollution in the future. Results A bibliometric analysis was conducted based on 3407 publications retrieved from the Web of Science during 2012–2021. China, USA and UK were the most productive countries. Sci. Total Environ, Environ. Sci. Pollut. Res, and Water were the most productive journals. The NPS pollutant, pollution types, driving forces, technology and the research object were retrieved from the keywords analysis. The common NPS pollutants of nitrogen, phosphorus, and heavy metals grabbed the highest attention, while the emerging contaminants have attracted increased attention. The migration and transformation of agricultural NPS pollution and urban NPS pollution driven by climate change and land use change were hot issues related to NPS pollution studies. Technologies related to the combination of 3S technology (RS, GIS, and GPS) and NPS pollution models, the sustainable control technologies, the technology of accurate traceability and automatic monitoring, and the comprehensive management plan were the important research areas related to NPS pollution. Although the research locations were mostly concentrated in the surface water and groundwater, the ocean and drinking water have great potential for future research. Conclusions This study illustrates the global focuses related to NPS pollution during 2012–2021 according to analyzing the publication outputs, source journals, source country, author, institution and the high-frequency keywords. Results demonstrated that the migration and transformation mechanism and ecological risk assessment for heavy metals and emerging pollutants, accurate traceability techniques, sustainable ecological restoration control techniques, and marine pollution have attracted rising attention. Additionally, developing countries will have a higher interest in NPS pollution in the future, because developed countries have already made great progress in controlling NPS pollution.

“…This ill-conceived and extensive reliance on chemical input in our farming system would intimidate the environmental sustainability and the agribusiness connected with agricultural products. Improper application of chemical, and agricultural inputs, including chemical fertilisers and pesticides (organophosphate, organochlorines, carbamates/ dithiocarbamates, and synthetic pyrethroids), could lead to detrimental effects on the environment through excessive soil erosion, surface water and groundwater pollution caused by the associated transport of sediment, chemical fertilisers and pesticides runoff and greenhouse gas emission (Opoku-Kwanowaa et al, 2020). Moreover, an ever-increasing amount of fertilisers and pesticides commonly used in conventional practices and the energy requirements for tilling to aerate soils and increasing irrigation have accelerated production costs.…”

Several decades after the green revolution, the agricultural industry depended on artificial chemical fertilisers to achieve higher crop yields. This practice, however, contributes to a hazardous impact on the farming ecosystem, causing a smaller deposit of arable land for crop cultivation and production worldwide. Since the 2000s, people, industries, and governments are aware that it is time for everyone to shift to new technology which promotes responsible land use for agriculture. One of the technologies is plant growth-promoting rhizobacteria to enhance crop productivity and potentially rehabilitate soil health directly or indirectly. This review paper outlines the mechanisms used by plant growth-promoting rhizobacteria to promote plant growth. The tools could be opening up new ideas to address one of the recent and urgent world agriculture issues, food security.

“…Soaking root fertilizer application can alleviate the problem of nutrient uptake of seedlings [40,41], but large-scale fertilization will reduce the economic benefits and increase the cultivation time. Additionally, the traditional application of soaking root fertilizer for seedlings has a low utilization rate, an unreasonable formula, a low K content and a low proportion of organic fertilizer, which can easily cause soil and water pollution [42,43]. In conclusion, a method of soaking root fertilizer application for E. urograndis is urgently needed to reduce the cultivation costs in plantations and optimize the cultivation process.…”

We examined the feasibility of applying soaking root fertilizer to Eucalyptus urograndis seedlings by dipping the roots, and the effectiveness of the method for improving the overall growth quality of the seedlings by affecting root growth. The seedlings of E. urograndis in the Southern National Forest Seedling Demonstration Base in China were dipped with seven kinds of soaking root fertilizer formulas, while another group of clear water was set as a control. We regularly investigated the relationship between root traits and other seedling traits, and the formulas conducive to the high-quality growth of seedlings in one month and two months were screened by principal component analysis (PCA). The feasibility of applying soaking root fertilizer by dipping the roots was analyzed by comparing the difference between the formula and the control. The F2 formula had the best promoting effect on the growth and biomass of seedlings and the highest ground diameter within one month. The biomass, cumulative height growth, and average crown width were also the highest in the two months, but the decreasing growth height in F2 was also obvious, along with reduced photosynthesis and root morphology. The F8 and F4 formulas as compound fertilizers showed the potential of a high growth rate and high quality. The seedlings on which they were all applied had an excellent photosynthetic capacity and a well-developed root system. A correlation analysis showed that root traits were significantly correlated with some aboveground indices of seedlings (growth, biomass and nutrients, etc.), among which the root K concentration was very significantly correlated with photosynthetic capacity, and the root P was very significantly correlated with seedling biomass. Dipping roots mainly promoted the uptake of P and K nutrients by roots, which had a positive effect on seedling photosynthesis and the root system, and thus improved the growth increment and growth quality of seedlings. A principal component analysis showed that dipping roots significantly promoted the growth traits of seedlings, and the best-performing formula for dipping roots was F8 at one month of growth. F4 was the best choice for growth at two months. F4 showed excellent performance in all trait indices and was the only treatment where an increase in the rhizome-to-stem ratio occurred, indicating that the nutrient distribution of F4 seedlings was uniform and efficient, which compensated for the deficiency of the follow-up fertility of the quick-acting complex fertilizer. The scientific formula of soaking root fertilizer can be economically applied by dipping roots to synchronously promote early growth and quality of seedlings, which can provide a theoretical basis for the early large-scale cultivation of E. urograndis and other plants.
