The Century Experiment at the Russell Ranch Sustainable Agriculture Facility at the University of California, Davis provides long-term agroecological data from row crop systems in California's Central Valley starting in 1993. The Century Experiment w

One of our current challenges is to quantify the mechanisms, capacity, and longevity of C stabilization in agricultural lands. The objectives of this study were to evaluate the long-term (10 yr) role of C input in soil organic carbon (SOC) sequestrat

Reported increases in crop yields over the first few years of organic farming (especially during the 3-year ‘‘transitional’’ period established in US law) have been attributed to gradual improvements in soil properties, such as the capacity o

The Long-Term Research on Agricultural Systems (LTRAS) experiment has been monitoring the long-term effects of conventional and alternative practices on crop yields and soil properties since 1993, with a planned duration of 100 years. Data for the fi

Computer models may be useful tools to design management practices for green manures, to maximize N uptake by the following crop while minimizing N losses to leaching. A previous paper tested CERES models predictions of soil processes in the absence

Nitrogen release into soil from a legume cover crop (LCC) is affected by soil biotic and abiotic factors, quality of the LCC incorporated, and management practices. This study was conducted to test the ability of the CERES soil-process submodels to p

Long-term use of fallow in dryland wheat (Triticum aestivum L.) systems can increase erosion and decrease soil fertility. One possible solution is to grow a green manure crop during the fallow period. To evaluate the short-term effects of substitutin

Color infrared aerial photos can be scanned into a computer file and then analyzed using image-processing software. This relatively new technology is illustrated using examples from two long-term research projects at UC Davis. A “vegetation index

Partitioning efficiencies of plant dry matter (harvest index, or HI) and N (NHI) to grain are determinants of economic yield and protein content of wheat (L.). Response of HI and NHI to a range of early- and late-season N-supply environments was char
