近日,郑州大学农学院陈杰教授团队在国际知名期刊《Soil Science Society of America Journal》(美国土壤学会会刊)上发表了题为“Using a variety of machine learning approaches to predict and map topsoil pH of arable land on a regional scale”的长篇研究论文...
中国科学院植物研究所杨元合研究组以青藏高原多年冻土区为研究对象,基于大尺度野外取样,通过多种研究手段,包括胞外酶化学计量、元素阈值比、功能基因丰度和养分添加实验,揭示了冻土区土壤微生物养分限制特征。研究人员基于4种方法得到的结果一致显示,冻土区土壤微生物受氮磷共同限制。并且,与冻土层相比,活动层土壤微生物养分限制程度更强。进一步研究发现,土壤资源化学计量和真菌细菌比是微生物养分限制空间变异的主要驱...
近日,云南农业大学张乃明教授团队在高地质背景区土壤-作物系统金属元素的污染水平及潜在风险研究取得最新进展。该研究成果以“Contamination levels of and potential risks from metal(loid)s in soil-crop systems in high geological background area”为题发表在环境科学国际知名TOP期刊《Sci...
近日,陈晓明教授课题组在锶污染土壤的植物-微生物联合修复方面取得最新研究进展。相关成果发表在国际期刊环境科学与生态学领域《Journal of Hazardous Materials》(IF=14.224, 中科院分区一区TOP期刊)上,题目“Combined forage grass-microbial for remediation of strontium-contaminated...
工业革命以来,化石燃料燃烧和农业化肥使用等人类活动导致大气氮沉降增加。持续的氮输入会显著改变陆地生态系统结构和功能。作为表征微生物生理代谢的重要指标,土壤微生物碳利用效率(CUE)决定着微生物将吸收的碳分配至其生长和呼吸的比例,在很大程度上调控着氮输入背景下的土壤碳固持与分解过程。因此,阐明土壤微生物CUE对氮富集的响应机制是准确预测氮输入背景下土壤碳动态的前提。以往的研究主要关注氮输入引起的土壤...
中国科学院植物研究所植被与环境变化国家重点实验室黄振英研究组等研究人员合作开展地上下生物多样性关系的研究,该研究在对中国北方半干旱区草原进行连续两年1700公里样带调查的基础上,通过测量叶、茎性状来刻画植物功能多样性,并利用高通量测序技术量化土壤细菌和真菌多样性,以及真菌中的病原真菌、腐生真菌和丛枝菌根真菌(AMF)的多样性。研究发现植物多样性(物种多样性和功能多样性)与土壤真菌多样性存在较强的耦...
美国农业部国家农业统计局(NASS,USDA)联合美国宇航局(NASA)和乔治梅森大学(George Mason University)合作开发了一种可使使用者直接获取NASA高分辨率土壤湿度数据的“作物状况和土壤水分分析工具”(Crop CASMA)。
Rice University scientists are cleaning soil contaminated by oil spills in a way that saves energy and reclaims the soil’s fertility.They use a process known as pyrolysis, which involves heating ...
The National Science Foundation (NSF) has invested $55.5 million in three new Engineering Research Centers (ERCs) to create novel technology platforms and transform industries. These three ERCs will a...
Agriculture Deputy Secretary Kathleen Merrigan today announced that soil erosion on cropland declined by more than 40 percent during the past 25 years, while more than one-third of all development of ...

New training in managing soil biology is being developed after feedback from well attended field days and workshops in Central and Northern NSW last year.More than 200 landholders in those regions too...
As part of project SoilTrEC, experts from the University, along with others in Europe, USA and China, have established networks of field research stations to study the valuable services that soils pro...
Known as the father of the “Green Revolution,” Borlaug has been commended for his contributions to agricultural science and his ability to influence political policy. He is one of only five people in ...
Odor complaints related to animal production have increased during the past decade. Swine slurry stored in open storages is a source of airborne contaminants, including ammonia and odorous compounds. ...
A new book published by the Soil Science Society of America (SSSA), titled, Soil Carbon Sequestration and the Greenhouse Effect: Second Edition, addresses this topic and provides new perspectives as t...
