“…In the SPAC, evapotranspiration (ET) is an important variable in water resource management. Evapotranspiration is a key climate variable closely linked to water, energy and carbon cycles and is crucial to the study of regional vegetation cover change (Fang et al 2020;Li et al 2020a;Liu 2022;Ndulue and Ranjan 2023). Climate change has become increasingly serious in recent years due to the occurrence of global warming caused by massive emissions of greenhouse gases.…”

“…This method can simply and effectively estimate the actual evapotranspiration and has been widely used in grassland and farmland water management (Wu et al 2017;Li et al 2020b). At present, there are many models for estimating reference crop evapotranspiration based on temperature and radiation data (Kisi 2014;Han et al 2022;Liu et al 2022). These models are derived from experiments or theories, so the test conditions are different, the required input data is different, and the applicable region is different.…”

Evapotranspiration is an important part of the hydrological cycle and a key indicator to measure hydrological and energy transfer in the soil-plant-atmosphere continuum (SPAC). In this study, maize farmland in the lower Yellow River, an important grain production base in China, was selected as the research object. Based on the actual observation data of the eddy covariance system during the summer maize growth cycle, ten common evapotranspiration estimation models, including the FAO-56 Penman‒Monteith (P-M) model, Hargreaves–Samani (H-S) model, Priestley–Taylor (P-T) model, Makkink (Ma) model, Jensen–Haise (J-H) model, Irmark–Allen (I-A) model, Doorenbos–Pruitt (D-P) model, McCloud (Mc) model, Kimberly–Penman (K-P) model and Abtew (Ab) model, were evaluated in estimating the applicability of the actual evapotranspiration. The mean bias error (MBE), mean absolute error (MAE), root mean square error (RMSE), coefficient of determination (R2), Nash–Sutcliffe efficiency (NSE) and index of agreement (D) were chosen as evaluation indices. The Pearson correlation test and principal component analysis methods were used to explore the main influencing factors of actual evapotranspiration. The comprehensive ranking of the applicability of each model in the study area was obtained by synthesizing each index: J-H > P-T > Mc > K-P > I-A > P-M > D-P > Ab > Ma > H-S. it could be concluded that the J-H model was the most suitable in the study area, followed by the P-T model, while the H-S model attained the worst simulation performance. The evapotranspiration of summer maize at the tasseling-milky maturity stage in this region was the highest, and the solar radiation, net radiation and photosynthetically active radiation exhibited a strong correlation with evapotranspiration and greatly impacted evapotranspiration. This study plays an important role in the development of efficient water-saving agriculture, irrigation forecasting and sustainable utilization of water resources in the core area of grain production in China.

Phosphorus, as a key nutrient, plays an essential role in both algal growth in surface waters and crop development on land. Its presence in inorganic fertilizers is crucial for maximizing crop yields. However, an excessive accumulation of phosphorus in soils can lead to its loss and exacerbate eutrophication in water bodies. This study highlights the complex interplay among phosphorus management, agricultural productivity, and environmental health, particularly in the context of climate change’s influence on sediment transport and water pollution. We focus on the Poyang Lake Basin (PLB) and use a sophisticated process-based phosphorus model to forecast phosphorus load trends from 2020 to 2049. Our predictions indicate a significant increase in the total phosphorus load of the PLB due to the impact of climate change. To address these challenges, we explore a novel strategy combining organic and inorganic phosphorus fertilizers. This approach aims to improve crop yields while reducing non-point source phosphorus pollution through adjusted anthropogenic inputs. Our findings reveal that a synergistic application of these fertilizers, coupled with a controlled use of inorganic phosphate, can reduce its usage by more than 2.5% annually. This method not only contributes to a 2.2% average annual increase in livestock and poultry production but also promotes a 0.6% yearly growth in grain output. Consequently, it effectively diminishes non-point source phosphorus pollution, offering a sustainable solution to the dual challenge of enhancing agricultural productivity and protecting environmental health.
