Maize Production and Soil Properties Change in Alley Cropping System at Different Nitrogen Levels
Productivity of maize and soil properties change under alley cropping system consisting of four woody species (Gliricidia sepium, Leucaena leucocephala, Cajanus cajan and Senna siamea) at different nitrogen levels (0, 25, 50, 75 and 100% of recommended rate) were studied in the floodplain ecosystem of Bangladesh. Comparative growth performance of four woody species after pruning showed that L. ...
متن کاملSimulated effects of dryland cropping intensification on soil organic matter and greenhouse gas exchanges using the DAYCENT ecosystem model.
We present evidence to show that DAYCENT can reliably simulate soil C levels, crop yields, and annual trace gas fluxes for various soils. DAYCENT was applied to compare the net greenhouse gas fluxes for soils under different land uses. To calculate net greenhouse gas flux we accounted for changes in soil organic C, the C equivalents of N2O emissions and CH4 uptake, and the CO2 costs of N fertil...
متن کاملSoil Organic Carbon and Nitrogen Fractions in Temperate Alley Cropping Systems
Alley cropping may promote greater sequestration of soil organic carbon. The objective of this study was to examine spatial variability of soil organic carbon (C) and nitrogen (N) fractions relative to tree rows in established alley cropping systems in north central Missouri. Soils were collected to a depth of 30 cm from two alley cropped sites, a 19-yr-old pecan (Carya illinoinensis)/bluegrass...
متن کاملManagement of Dryland Cropping Systems in the U.S. Great Plains: Effects on Soil Organic Carbon
The expansion and intensification of agroecosystems worldwide has significantly affected the environment at multiple spatial scales (Matson et al., 1997). Agroecosystem effects on atmospheric constituents have altered local, regional, and global environmental quality through windblown soil (Zhang et al., 2001) and emission of particulate matter, reactive N (e.g., NH3 and NOx), volatile organic ...
متن کاملClimate Change Predicted to Negatively Influence Surface Soil Organic Matter of Dryland Cropping Systems in the Inland Pacific Northwest, USA
Soil organic matter (SOM) is a key indicator of agricultural productivity and overall soil health. Currently, dryland cropping systems of the inland Pacific Northwest (iPNW) span a large gradient in mean annual temperature (MAT) and precipitation (MAP). These climatic drivers are major determinants of surface SOM dynamics and storage characteristics. Future climate change projections through 20...
