The least-cost economic theory of photosynthesis shows that water and nitrogen are mutually substitutable resources to achieve a given carbon gain. However, vegetation in the Sahel has to cope with th...
2022年11月1日,农学院智慧农业团队在国际顶级遥感期刊《Remote Sensing of Environment》发表了题为“Estimating leaf nitrogen content by coupling a nitrogen allocation model with canopy reflectance”的研究论文,报道了他们在冠层尺度氮含量光谱监测普适性模型构建方面的重要进展...
Drought is a climatic event that considerably impacts plant growth, reproduction and productivity. Toona sinensis is a tree species with high economic, edible and medicinal value, and has drought resi...
Concerns over the use of nitrogen have been increasing due to the high cost of fertilizers and environmental pollutions caused by excess nitrogen application in agricultural fields. Several methods ar...
Hyperspectral LiDAR (HSL) is a novel tool in the field of active remote sensing, which has been widely used in many domains because of its advantageous ability of spectrum-gained. Especially in the pr...
A method for the rapid and nondestructive determination of total nitrogen content in soy sauce was explored. Prediction models were established using near-infrared spectroscopy combined with each of t...
Although soil nitrate nitrogen (N) is a nutrient source for crop, it could be a potential nonpoint pollution source to the environment when its content remains high with an inappropriate management. S...
Two experiments were conducted to investigate the effects of dietary crude protein level and degradability on milk urea nitrogen (MUN) content. In experiment 1, twelve multiparous lactating cows avera...
Forests occupy one third of the world’s land area and govern carbon (C) transfers and influence nitrogen (N) content in the biosphere. Afforestation leads to soil changes of specific dynamics, often a...
Although soil nitrate nitrogen (N) is a nutrient source for crop, it could be a potential nonpoint pollution source to the environment when its content remains high with an inappropriate management. S...
The basic nutritional aspects and parameters of freshwater and marine algal food products are described. Blue-green algae (Spirulina pacifica, S. platensis), green algae (Chlorella pyrenoidosa), red a...
The photosynthetic rate in the flag leaf of rice at the full heading stage was examined in three japonica varieties, Koshihikari, Aikoku and Asanohikari, and the indica high-yielding variety Takanari ...
Here, we present bulk organic geochemical data from a spatial grid of surface samples from the western Barents Sea region. The results show that the distribution of organic carbon in surface sediments...
For a general assessment of the nitrogen status of sugi plantations in Japan, we measured nitrogen content in the needles of sugi (Cryptomeria japonica D. Don) trees growing at 531 sites across the co...
Konjak plants (cv. Zairai) were grown in pots using 2-year-old seed corms of 75 g in weight, containing different amount of nitrogen. The leaf area, dry weight and amount of nitrogen absorption were m...
