The Billa Billa Folow Management Experiment was initiated in 1983. The soil
parent material at the site consists of cretaceous sediments (lithic
sandstone). The native vegetation was cleared in 1971. ...
This experiment began in 1843. The site was possibly farmed since
Roman times (i.e at least 1500 years). Map of 1623 shows field in
arable use. 1839-1843 arable crops: turnips, barley, peas, wheat, ...
This data set contains results from field CO2-enrichment experiments conducted
over five consecutive growing seasons, 1983-1987. These results comprise data
concerning the effects of continuous CO2 ...
The purpose of the "Carbon Dioxide and Climatic Change Effects
on Crops and Trace Gas Exchange with the Atmosphere" dataset is
to determine the effect of elevated CO2 and temperature on
The objective of the "Carbon Sequestration by Switchgrass
Managed as an Energy Crop" dataset is to monitor carbon
sequestration over time in switchgrass and to compare the
economic and carbon sequestration ...
(adapted from project summary)
Problems: Carbon in soils varies quantitatively and with depth
depending on theland use management. Some management practices allow
for considerable sequestration and ...

1. Conventional tillage continuous cotton production severely depletes
soil carbon and degrades the soil.
2. There is a paucity of data related to long-term ...
The objective of "Carbon and Water Fluxes From Irrigated Corn: A
Field-Scale, Full Season Study" is to evaluate the flux of

also contains ...
This web site allows users to stipulate the criteria they are
looking for in their search of trees and shrubs. The user can choose
from subcatagories under:
Leaf flushing period ...
The Deherain long-term field experiment was started in 1875 to study the
impact of fertilization on crop yield. Before 1875, the soil was
cultivated with alfalfa without fertilization. Between 1929 ...
(adapted from project description)
Problem: The need to assess impact of conventional and sustainable
agricultural practices on soil quality requires development of routine
procedures that can rapidly ...
"Effect of Drought Stress on Oilseed Quality" is a complex of
datasets on a series of experiments over the last 5 years of
research on drought stress. Datasets include:

The purpose of "Effects of Nutrient Transport in Cropping
Systems in Environmental Quality and Fertilizer Efficiency" is
to assess dynamic nitrogen (N) transport in high-residue
Most sustainable development decisions require trade-offs between the often
conflicting goals of different sectors GIS technology helps cross-sectoral
communication by not only providing very powerful ...
Problem: Soil organic carbon levels have declined to about 50% of
their original levels in much of the Northern Great Plains due to
intensive tillage and a wheat - fallow rotation.
Findings: A field ...
The objective of "Heat and Oxygen Stresses and Rotations as
Alternatives to Methyl Bromide in Crop Production" is to
