Abstract:
... Take‐Home Message Climate warming is transforming the Arctic at an unprecedented rate with previously barren and sparsely vegetated landscapes undergoing “greening”. We postulate that the observed vegetation changes throughout the Arctic are not only tied to warming, but to changes in soil properties and their impacts on plants and soil microbial communities. A key to understanding extent and patt ...

Abstract:
... Mineral weathering bacteria play essential roles in nutrient cycling and plant nutrition. However, we are far from having a comprehensive view of the factors regulating their distribution and the molecular mechanisms involved. In this review, we highlight the extrinsic factors (i.e., nutrient availability, carbon source) and the intrinsic properties of minerals explaining the distribution and func ...

Abstract:
... Nitrogen nutrition index (NNI) is determined by using costly and time-consuming sampling methods during the growing season. The present study primarily aims to estimate NNI during the growing season of maize. Dry matter (W) and nitrogen uptake (Nu) during the growth period were estimated by AquaCrop and HYDRUS-2D models, respectively, as the two key parameters for determining NNI. The treatments w ...

Abstract:
... The coming 10–20 years will be most critical for making the transition to a global food system in which mineral nutrients in agriculture must be managed in a more holistic manner. Fertilizers play a particular role in that because they are among the key drivers for securing global food security and improving human nutrition through increased crop yields and nutritional quality. A new paradigm for ...

Abstract:
... The goal of this study was to establish the feasibility of using the critical nitrogen (N) dilution curve of cotton leaves for diagnosing N nutrition, so as to provide a theoretical basis and guidance for accurate fertilization in drip-irrigated cotton fields. We conducted field experiments using Lumianyan 24 under four different reduced N treatments including (506 kg hm⁻² (N1), 402.5 kg hm⁻² (N2) ...

Abstract:
... For many years after the discovery of the two stable isotopes of B (¹⁰B,¹¹B) in 1920 it was not used routinely as a tracer in the biological sciences until the development of inductively coupled plasma mass spectrometry in the early 1980s. This development provided an impetus to the study of the role of B in plant nutrition, although many seminal discoveries were made beforehand without the aid of ...

Abstract:
... The goal of this research is to determine the effect of poultry manure and irrigation on the yield and quality of potatoes (Solanum tuberosum) grown in fields located on the southern steppe of the Republic of Bashkortostan. Before the poultry manure was added, it was treated with a microbiological fertilizer to suppress pathogenic microflora. Potato tubers were pretreated with an insectofungicide ...
