Soil, Water, and Irrigation - General Publications
Full Title: Classification of Conservation Tillage Practices in California Irrigated Row Crop Systems. Tillage has been practiced for nearly as long as there has been agriculture. New techniques in use now can reduce erosion and soil damage.
California Master Gardener Tip Sheet. The title says it: Composting is a good thing! Learn what to compost, how to manage your compost pile and how to use the finished product. Three mini-posters, four pages of text, plus links to useful resources.English edition of "El compostaje es bueno para su jardín y el medio ambiente" (Publication 8367s).
"Conservation tillage" is an approach to soil management that balances the short-term need for a profitable crop with the long-term need for sustainably healthy ground. This publication looks at ways to control weeds while practicing conservation tillage.
Conservation tillage farming systems protect water and soil resources while still letting the grower produce a commercially viable crop. Less tillage also means less labor and equipment time, and that translates into lower overall production costs.
Plants may grow poorly for many reasons, and many of those may lie underground in the soil. Learn to identify a number of common soil problems so you can seek help to fix them. This is an unaltered scan of the 1976 print edition, now available as an Adobe Acrobat PDF document.
Serpentine and related rocks sometimes contain naturally occurring asbestos (NOA). When these rocks break down into soil, the NOA comes with them, and that creates a health hazard. Learn to recognize serpentine soils and keep health risks to a minimum.
Here's an environmentally friendly, low-maintenance way to get a "grassy" groundcover in your landscape. Winner of the American Society for Horticultural Science 2010 Outstanding Extension Division Educational Materials Award.
Full title: Reducing Runoff from Irrigated Lands: Erodibility of Agricultural Soils, with Examples in Lake and Mendocino Counties. Soil erosion is a major cause of water quality degradation. Included is an introduction to the properties of soil that influence its erodibility and an explanation of soil properties that you can manage to minimize erosion.
Full title:Reducing Runoff from Irrigated Lands: Orchard Floor Management Practices to Reduce Erosion and Protect Water Quality. Water-induced erosion carries valuable soil out of orchards and into downstream waterways, where it can cause serious problems. Learn how to keep your soil where it will do you the most good.
Since the 1950s, the Storie Index has been used to rate California soils for land use and productivity. Now UC researchers have developed a revised Storie Index that generates ratings automatically from digital soils data available from USDA.
Specific steps you can take to minimize vineyard and orchard soil erosion and keep downstream waterways clean.
A brief explanation of the soil types and grades in the Storie Index soil rating system, first developed in 1933 by R. Earl Storie.
When gardening in serpentine soils, you need to avoid exposure to naturally occurring asbestos (NOA) and some heavy metals. Here are precautions you can take in the garden along with a list of trees and shrubs you can plant to help stabilize these soils.
A soil's physical and chemical properties determine whether it is vulnerable to erosion, which can reduce soil quality and cause other problems besides. Learn the basics of identifying what type of erosion is affecting your land and what's causing it.
Irrigated orchards, vineyards, and row crops have high erosion rates. The vegetative filter strip (VFS) offers one way to control erosion rates and keep soil in the field rather than letting it be carried off site in drainage water.
