This publication is the third in a series on high residue farming (HRF), for farmers who are interested in HRF. It discusses residue management after harvest and explains how to plant crops into high residue conditions with a planter or drill. It also covers modifications for existing equipment such as planters and drills, and soil fertility adjustments that may be necessary. EM073E.
This publication is the second in a series on high residue farming (HRF), for farmers who are interested in HRF. It discusses how to choose a cropping sequence, choosing specific cover crops, and special crop considerations for irrigated cropping systems in the far western United States. It includes a very helpful table of crops that shows the relative difficulty of specific rotations. EM072E.

Extension Bulletin EM036E. Strip-tillage is a low-impact cultivation technique suited to irrigated land with a lot of residue from a previous crop. A strip-till system creates both clean-till and high-residue conditions in the same field, taking advantage of both systems while minimizing drawbacks. This publication discusses the benefits of this system, as well as equipment needed, general management concerns, and how to get started. A budget is also included to help growers determine the relative net cost of implementing this system. Originally published Jan 2011; revised Sept 2014.

Cogger, C., A. Fortuna, D. Collins. Feb 27, 2014. The second of a two-part webinar series on Greenhouse Gas Emissions and Soil Quality in Long-term Integrated and Transitional Reduced Tillage Organic Systems.
This is the focus of our current research. How do different organic vegetable production systems affect N2O emissions, and how do other outcomes of those systems affect their potential for adoption?
- Systems include full tillage with high-carbon amendment (compost), full tillage with low carbon amendment (broiler litter), pasture-vegetable rotation, and reduced tillage cover crop mulch.
- Measurements include N2O and CO2 emissions, soil N, microbial ecology focused on denitrification organisms, crop yield, and soil quality. Measurements are focused on key times during the season, including amendment application and tillage, irrigation, and freeze-thaw.
Intended audience is other researchers, and interested extension faculty and farmers.
Cogger, C., A. Fortuna, D. Collins. Feb 25, 2014. The first of a two-part webinar series on Greenhouse Gas Emissions and Soil Quality in Long-term Integrated and Transitional Reduced Tillage Organic Systems.
Topics for this webinar include:
- Source and properties of N2O as a greenhouse gas, its relative contribution to global
- warming, and the role of agriculture in N2O emissions
- Review of the nitrogen cycle and the production of N2O
- The relationship between organic practices and N2O production
- How we measure N2O emissions
Intended audience is extension faculty and farmers who want a big picture perspective on why we’re interested in nitrous oxide emissions.

Carpenter-Boggs, L., Painter, K., and Wachter, J. Recorded webinar presentation delivered October 22, 2013. It covers a variety of reasons to integrate livestock into crop rotations, and summarizes past research on the topic. It is directed towards beginning growers interested in diversifying their income and crop rotations, towards educators and Extension workers, and towards a more general audience wanting to learn more about mixed crop-livestock systems.
CSANR webpage. Anaerobic digestion (AD) is a process in which organic matter is converted into methane by bacteria in the absence of oxygen. Under typical dairy farm conditions manure is stored in open ponds and applied to fields, where decomposition often occurs under anaerobic conditions. This leads to the natural, open-air production of methane, a greenhouse gas with more than 20 times the warming value of carbon dioxide. By enclosing, controlling and accelerating this natural anaerobic conversion process, not only can the methane be contained, but it can be converted to renewable energy, providing two mechanisms for carbon sequestration and global warming reduction – methane capture/conversion and fossil-fuel energy offset.
