Restoring soil health to reduce irrigation demand and buffer the impacts of drought

Frontiers of Agricultural Science and Engineering 2020, Volume 7, Issue 3, Pages 339-346 doi: 10.15302/J-FASE-2020348

Abstract:

Irrigation consumes three quarters of global water withdrawals each year. Strategies are needed to reduce irrigation water use, including increasing the efficiency of transfer methods and field application. Comprehensive restoration of soil health, specifically through organic matter amendments, can substantially reduce irrigation demand and increase crop yield. A program to restore severely degraded and desertified soils by incorporating coarse woodchips into the soil successfully increased rainfall capture and elevated soil moisture for several weeks between rainfall events at both Ningxia, north-west China and North Dakota, USA. With addition of fertilizer, woodchip incorporation further increased growth of wheat and alfalfa. Comprehensive soil health assessment of remnant grasslands was used to develop target reference soil profiles by which to guide restoration efforts. Given that most agricultural soils are degraded to some degree, soil health restoration can provide a powerful strategy toward achieving global food and water security.

A method to calculate working capacity space of multi-DOF manipulator and the application in excavating

Baochen WEI, Feng GAO

Frontiers of Mechanical Engineering 2012, Volume 7, Issue 2, Pages 109-119 doi: 10.1007/s11465-012-0323-6

Abstract:

Working capacity refers to the velocity output and force output of a manipulator.It is usually be represented by output capacity space.The results show that the effect of the gravity is a translation of the capacity space.This paper gives a method for the output capacity express especially for heavy duty manipulators.The output capacity space can be helpful to the driving parameters selection.

Polypropylene microplastics alter the cadmium adsorption capacity on different soil solid fractions

Frontiers of Environmental Science & Engineering 2022, Volume 16, Issue 1, Pages 3-3 doi: 10.1007/s11783-021-1437-z

Abstract:

Microplastics (MPs) are widely present in a variety of environmental media and have attracted more and more attention worldwide. However, the effect of MPs on the interaction between heavy metals and soil, especially in soil solid fraction level, is not well understood. In this study, batch experiments were performed to investigate the adsorption characteristics of Cd in bulk soil and three soil solid fractions (i.e. particulate organo matter (POM), organic-mineral compounds (OMC), and mineral) with or without polypropylene (PP) MPs.

Effects of riparian land use on water quality and fish communities in the headwater stream of the Taizi River in China

Sen DING, Yuan ZHANG, Bin LIU, Weijing KONG, Wei MENG

Frontiers of Environmental Science & Engineering 2013, Volume 7, Issue 5, Pages 699-708 doi: 10.1007/s11783-013-0528-x

Abstract: Riparian land use remains one of the most significant impacts on stream ecosystems. This study focuses on the relationship between stream ecosystems and riparian land use in headwater regions. Four riparian land types including forest, grassland, farmland, and residential land were examined to reveal the correlation between stream water and fish communities in headwater streams of the Taizi River in north-eastern China. Four land types along riparian of 3 km in length were evaluated at 25, 50, 100, 200 and 500 m widths, respectively. Generally, the results found a significant relationship between riparian land uses and stream water quality. Grassland was positively correlated with water quality parameters (conductivity and total dissolved solids) at scales from 100 to 500 m riparian width. Farmland and residential land was negatively correlated with water quality parameters at scales from 25 to 500 m and from 50 to 200 m riparian widths, respectively. Although the riparian forest is important for maintaining habitat diversity and fish communities, the results found that only fish communities were significantly correlated with the proportion of riparian farmland. Farmland had a positive correlation with individual fish abundance within a riparian corridor of 25 to 50 m, but a negative correlation with fish diversity metrics from 25 to 100 m. This study indicates that effective riparian management can improve water quality and fish communities in headwater streams.
