Management of Soil in Dryland RegionsEntry ID: USDA0381
Abstract: "Management of Soil in Dryland Regions" is a set of data, each dataset
representing 3 to over 20 years of data using replicated
trials. Tillage and cropping system-type studies have the longest
number of years in order to cover a wide range of climatic
conditions. Only a portion of one study is irrigated, the remainder
are grown under dryland conditions (average precipitation is 57
cm). The ... purpose of this set of data is to determine optimum
combinations of adapted crop varieties, tillage systems, crop
rotations, and fertility regimes that have long-term
sustainability. Develop management techniques to maximize organic
matter loading of agricultural soils in order to provide an
alternative to landfills for the disposal of non-toxic organic
materials. Synthesize data from long-term studies and analyze data in
an economic context in order to identify profitable cultural systems
and formulate best management recommendations.
Collection Organization: Kansas State University Agricultural
Experiment Station, with USDA/CSREES.
Collection Methodology: Winter, spring, and summer annual forages will
be tested under various tillage and nitrogen rates. Crop rotations
and residue levels as affected by tillage systems and added nutrient
will be evaluated annually during each phase of the rotation. The
capacity of soils to decompose non-toxic, biodegradable, organic
materials, to include yard waste and newspaper, will be studied on a
crop-fallow (dryland) and continuous cropping (irrigated)
systems. Results of long-term dryland management studies will be
synthesized in an attempt to extract generalized system responses that
account for annual fluctuations in precipitation and economic
Collection Frequency: Most of the data is collected annually per
Update Characteristics: The yield portion of the long-term
datasets are updated.
Most of the datasets for a particular study on one floppy disc.
Due to size, two or more discs are required.
Data Center: USDA Cooperative State Research, Education, and
Dissemination Media: Data collected are on 3.5 inch floppy disc
and on a hard copy.

Quality Prepackaged seed is counted, fertilizer is weighed, and field
randomization sheets ensure precise experimental procedures.
Each study has 3 or 4 replication. The data are analyzed using
SAS. Note taking, plant sampling, harvest, etc. is done on an
individual plot basis.
