How soil carbon fractions relate to soil properties and crop yields in dryland cropping systems?
Soil Science Society of America Journal, 2022Abstract Soil labile C fractions have been proposed as promising soil health indicators, but they have not been related to extensive soil properties and crop yields. We evaluated the relationships among soil organic carbon (SOC), labile C fractions, 62 soil physical, chemical, biological, and biochemical ...

Managing Crop Residues to Optimize Crop/Livestock Production Systems for Dryland Agriculture
1990An important conclusion of the recent International Conference on Dryland Farming was that dryland agriculture must play an increasingly important role in meeting future world needs for food and fiber (International Conference on Dryland Farming, Executive Summary, 1989).

Moisture Storage and Use by Dryland Spring Wheat Cropping Systems
Soil Science Society of America Journal, 1962Abstract Soil moisture data collected at Mandan, North Dakota from 1915 to 1954 were summarized to compare water storage and use from soil annually cropped to spring wheat and alternately fallowed and cropped to spring wheat. Consecutive 2‐year periods were used for the comparisons. The periods of study began with time of harvest.

Soil Organic Matter Changes in Intensively Cropped Dryland Systems
Soil Science Society of America Journal, 1999Abstract Continuous cropping or decreasing the frequency of summer fallow (F) in cereal‐based dryland rotations may have benefits other than greater water utilization and erosion control. We hypothesized that rotations with no fallow or minimum fallow frequency can produce more biomass and cover than the ...

Efficient Water Use in Dryland Cropping Systems in the Great Plains
Agronomy Journal, 2005Successful dryland crop production in the semiarid Great Plains of North America must make efficient use of precipitation that is often limited and erratic in spatial and temporal distribution. The purpose of this paper is to review research on water use efficiency and precipitation use efficiency (PUE) as affected by cropping system and management in ...

Legume-wheat rotation in dryland cropping systems in eastern Colorado
2001In the Great Plains of the United States, hard red winter wheat (Triticum aestivum L.) is the dominant dryland crop. A fallow period of approximately 14 months is used to increase soil water storage and enhance yield. This technique has a low precipitation storage efficiency and produces soil degradation.

Land Degradation & Development
ABSTRACT The rapidly growing global population, projected to increase by 50% by 2050, coupled with climate change, necessitates a sustainable transformation of agricultural systems to ensure food security. In dryland ecosystems, it shows an aridity index of < 0.65, supports extensive livestock grazing and sustains ~38% of the ...

Fertility management in dryland conservation cropping systems of the Pacific Northwest
American Journal of Alternative Agriculture, 1996The Pacific Northwest dryland region is moving toward conservation tillage to control excessive erosion on steep slopes, but progress has been slow because of adverse effects on plant growth and yield. Fertility relations in cereal grains with conventional tillage are well known, with deficiencies occurring for nitrogen, sulfur, and phosphorus, in ...
