RETRIEVAL AND MAPPING OF HEAVY METAL CONCENTRATION IN SOIL USING TIME SERIES LANDSAT 8 IMAGERY
Soil heavy metal Time series Remote sensing imagery Landsat Retrieval Model selection
2018/5/14
Heavy metal pollution is a critical global environmental problem which has always been a concern. Traditional approach to obtain heavy metal concentration relying on field sampling and lab testing is ...
Soil water regime estimated from the soil water storage monitored in time
ecology classification soil water regime soil water content monitoring soil water storage
2015/2/3
During the vegetation season, the water storage in the soil aeration zone is influenced by meteorological phenomena and by the vegetated cover. If the groundwater table is in contact with the soil pro...

soil erosion by water soil loss RUSLE time-variable characteristics of crops effective root mass canopy cover fall height
2015/1/28
To determine specific characteristics necessary for the computation of the C factor in RUSLE for timevariable crops, measurements were carried out in fields with selected agricultural crops grown by c...
土壤镰孢菌Real-Time QPCR定量方法的建立及应用
镰孢菌 实时荧光定量PCR 绝对定量
2015/9/28
基于镰孢菌ITS序列，设计一对应用于实时荧光定量PCR（Real-Time QPCR）反应的镰孢菌属特异性引物TS和TR，并建立了相应的Real-Time QPCR体系。应用该反应体系，绝对定量了无肥(NF)、化肥(NP)以及化肥配施有机肥(NPM)等 3 种施肥措施下大豆田土壤镰孢菌DNA含量。结果表明：引物TS和TR对镰孢菌属真菌有较好的特异性；Real-Time QPCR反应的扩增曲线中各梯...

Time-dependent changes in distribution patterns of soil bulk density and penetration resistance in a rangeland under overgrazing
Bulk density overgrazing penetration resistance rangeland soil compaction spatial variability
2011/3/29
High soil bulk density and penetration resistance as an indication of soil compaction affect soil infiltration and
runoff. Overgrazed rangelands are under severe erosion risk because of soil compacti...

2009/7/8
In order to understand the effect of the time of nitrogen topdressing (panicle formation stage — 40 days after heading time) on the recovery rate of applied nitrogen and its distribution in rice plant...
Remote real-time monitoring soil water potential system based on GSM
Soil water potential real-time monitoring negative pressure meter
2009/3/4
Aiming at the limitation of traditional measuring soil water potential, the paper presents an information system based GSM to real-time monitor data coming from multiple data sources. The monitoring...
Effects of hydraulic retention time and media of constructed wetland for treatment of domestic wastewater
