LINKING CROP WATER PRODUCTIVITY TO SOIL PHYSICAL, CHEMICAL AND MICROBIAL PROPERTIES
《农业科学与工程前沿(英文)》 2021年 第8卷 第4期 页码 545-558 doi: 10.15302/J-FASE -2020349
Agriculture uses a large proportion of global and regional water resources. Due to the rapid increase of population in the world, the increasing competition for water resources has led to an urgent need in increasing crop water productivity for agricultural sustainability. As the medium for crop growth, soils and their properties are important in affecting crop water productivity. This review examines the effects of soil physical, chemical, and microbial properties on crop water productivity and the quantitative relationships between them. A comprehensive view of these relationships may provide important insights for soil and water management in arable land for agriculture in the future.

Soils provide the structural support, water and nutrients for plants in nature and are considered to be the foundation of agriculture production. Improving soil quality and soil health has been advocated as the goal of soil management toward sustainable agricultural intensification. There have been renewed efforts to define and quantify soil quality and soil health but establishing a consensus on the key indicators remains difficult. It is argued that such difficulties are due to the former ways of thinking in soil management which largely focus on soil properties alone. A systems approach that treats soils as a key component of agricultural production systems is promoted. It is argued that soil quality must be quantified in terms of crop productivity and impacts on ecosystems services that are also strongly driven by climate and management interventions. A systems modeling approach captures the interactions among climate, soil, crops and management, and their impacts on system performance, thus helping to quantify the value and quality of soils. Here, three examples are presented to demonstrate this. In this systems context, soil management must be an integral part of systems management practices that also include managing the crops and cropping systems under specific climatic conditions, with cognizance of future climate change.

地球是一个动态系统。从常温常压到地核的360 GPa 和6600 K,地球的热力学状态随着深度的变化而发生很大变化。因此,地球成分(如硅酸盐和碳酸盐矿物)的物理和化学性质受其所处环境的显著影响。在过去的30 年中,在极端条件下的材料表征的实验技术和理论模拟方法都取得了巨大的进步。这些进步提升了我们对矿物特性的理解,这对于充分认识这个星球的形成及其生命起源至关重要。本文回顾了用于预测极端条件下材料性质的最新计算技术,本研究仅限于应用第一原理分子动力学(first principle molecular dynamics, FPMD)方法研究与地球科学相关的化学和热力学输运过程。
