Where Do Nutrients Go When You Irrigate
Fernandez, Thomas R. (Michigan State University)
This article covers irrigation management with an emphasis on nutrient retention. Prevent over-irrigation by understanding how water is held in containers. There are many links provided to assist you in skillful irrigation management.

Improving Irrigation Efficiency Reduces Water Use
Ristvey, A., Oki, L.R., Haver, D.L., and B.J.L. Pitton (University of California Davis)
A high level of irrigation application uniformity is essential to maximize irrigation efficiency and several strategies are available to audit irrigation systems. Limitations in system design and uniformity can decrease water availability and distribution, thereby hindering efforts to provide sufficient water to plants. Inadequate plant water can reduce growth and quality, decreasing saleable product and profits, while potentially creating environmental problems. Discussed in this article are irrigation system best management practices (BMPs) to improve water use efficiency (WUE), with the potential to increase the amount of water available for distribution and decrease waste.

Slow Sand Filters
Pitton, B.J.L., Oki, L.R. (University of California Davis), White, S.A (Clemson University)
Slow sand filters (SSF) can provide high-quality water from untreated sources like irrigation runoff. SSFs consist of a sand bed with about three feet of water above that flows through the sand via gravity. A microorganism community develops on the sand that has the ability to remove plant pathogens, including water molds, viruses, bacteria, and fungi. Flow rates are approximately six inches per hour so they can occupy a large area if sizable volumes of water need to be treated. However, SSFs are simple to install and are fairly cheap to operate compared to other treatment technologies.
