Impact of water quality, cultivation, and cropping systems on infiltration and physical properties of an arid clay soil
aggregate stability crop cover infiltration tillage wastewater
2015/3/10
Irrigation with treated wastewater is essential for increasing crop production in arid and semi arid regions. Field experiments were conducted on rainfed clayey soil to investigate the impact of water...
Developing an Efficient Cover Cropping System for Maximum Nitrogen Recovery in Massachusetts
automated lysimeter corn silage gepgraphical information system Nitrogen management rye winter cover crop soil water sampler
2014/11/4
Time of planting plays a critical role in nitrogen (N) uptake by rye cover crop (CC). Even a few days of delay in planting can severely decrease CC performance. Evaluating the amount of N accumulation...

Cover Plants Hot-Spot Variability Mini- and Micro-satellite
2013/2/27
In this research, soil microbial structures under a wheat triennial monoculture and horse bean-wheat-horse bean succession were evidenced using a metagenomic approach. Polymorphism analysis of DNA ext...
Cropping frequency and N fertilizer effects on soil water distribution from spring to fall in the semiarid Canadian prairies
Fallow Frequency Water Use Plant Biomass Spring Wheat Soil Water
2013/3/4
In the semiarid Canadian prairies, water is the most limiting and nitrogen (N) the second most limiting factor influencing spring wheat (Triticum aestivum L.) production. The efficiency of water-and n...

Lipid Biomarker Alfalfa Hay Corn Agroecosystem
2013/3/4
Soil microbial community structure is clearly linked to current plant species composition, but less is known about the legacy effects of plant species and agricultural management practices on soil mic...
Long-term rice-based cropping system effects on near-surface soil compaction
Bulk Density Crop Rotation Soil Organic Matter Tillage
2013/3/4
Irrigated rice (Oryza sativa L.) production is as-sociated with frequent cycling between anaero-bic and aerobic conditions, which can lead to a greater rate of soil organic matter (SOM) de-composition...
Effects of different levels of compost application on amounts and distribution of organic nitrogen forms in soil particle size fractions subjected mainly to double cropping
Compost Application Upland and Paddy Fields Soil Organic N Forms Size Fractions
2013/3/4
Effects of different levels of compost application on the amounts and percentage distribution of organic N forms in whole soils and particle size fractions were investigated. Soil samples were collect...
