High phosphorus (P) concentrations are commonly observed in lakes during algal blooms despite massive efforts on external nutrient reduction. However, the knowledge about the relative contribution of internal P loading linked with algal blooms on lake phosphorus (P) dynamics remains limited. To quan …
Soybean breeding is typically conducted in soils with favourable soil phosphorus yet soil P levels are typically low in sub-tropical regions. This study was conducted to determine yield progress of soybean cultivars released between 1995 and 2016 in sub-tropical parts of south-west China and grown at both low and high P …

This study used substance flow analysis to create a phosphorus accounting framework for China's natural and artificial systems, tracking 110 flows of 137 products in 31 provinces in 2020. The results show that mining is the largest phosphorus output node in China, followed by the phosphorus chemical industry and food processing industry.
1. China Mine production: 85 million MT. China's phosphate production decreased in 2022 to 85 million metric tons (MT), down from 90 million MT in 2021, but it is still first on the list of top ...
Estimation on total phosphorus of agriculture soil in China: a new sight with comparison of model learning methods. Soils, Sec 5 • Soil and Landscape Ecology • …
China is suffering from the depletion of high-quality phosphate rock, and there is severe environmental damage caused by the low phosphorus utilization efficiency. Globally, the quality of the remaining phosphate rock is also declining.
Physiological and molecular responses in phosphorus-hyperaccumulating Polygonum species to high phosphorus exposure Plant Cell Environ. 2024 Apr 3. ... 2 State Key Laboratory of Crop Gene Exploration and Utilization in Southwest China, Sichuan Agricultural University, Chengdu, Sichuan, China.
Here we show that the average concentrations of nitrogen and phosphorus in lake sediments have increased by 267% and 202%, respectively since 1850. In the model projections, 2030–2100, the ...
Future phosphorus (P) shortages could seriously affect terrestrial productivity and food security. We investigated the changes in topsoil available P (AP) and total P (TP) in China's forests, grasslands, paddy fields, and upland croplands during the 1980s–2010s based on substantial repeated soil P measurements (63,220 samples in the 1980s, 2000s, and …
Reactions of phosphorus fertilizers with and without a fertilizer enhancer in three acidic soils with high phosphorus‐fixing capacity. Soil Sci. Soc. Am. J., 82 (2018), pp. 1124-1139, 10.2136/sssaj2018 ... National estimates of environmental thresholds for upland soil phosphorus in China based on a meta-analysis. Sci. Total Environ., 780 ...
Thinning can improve soil nutrient supply, but the effects of thinning on soil phosphorus (P) contents and bioavailable mechanisms in high-density and short-rotation Eucalyptus coppice forests are not well reported. Therefore, we conducted five intensities of thinning treatments, which were 83% (283 tree ha−1, T1), 66% (566 tree ha−1, T2), 50% …
Phosphorus (P) is an essential element for supporting our life and is a non-renewable resource. This study applied dynamic material flow analysis to elucidate the phosphorus flow characteristics in China over the period from 1990–2019. Based on this, we developed a P resource efficiency index system and further explored the potential …
High-resolution combined ZrO-Chelex diffusive gradients in thin film (DGT) probes were arranged to synchronously monitor the characteristics of labile phosphorus (P), iron (Fe), and manganese (Mn) in sediments from regions of varying trophic levels in Lake Taihu, China. Results showed that P release …
The river-dominated East China Sea (ECS) is one of the world's largest continental shelf seas (Fig. 1), directly receiving a large amount of terrestrial particulates (annually 5 × 10 8 tonnes) mainly from the Yangtze River, the world's third largest river in terms of particulate loading (Xu et al., 2009).Sediments on the shallow margin sea are …
