Soil, Water, and Irrigation - General Publications
Furrow and sprinkler irrigation have long been used for California row crops, but drip irrigation now offers a number of advantages, particularly in areas to are subject to excess salts in soil and irrigation water. See if drip is right for your farm.
Catalog #8447
Water analysis by a commercial laboratory provides data on many parameters, some of which are of little significance for turfgrass irrigation. Learn which parameters are the most important for turfgrass management.
Catalog #8009
Full Title: Nonpoint Sources of Pollution in Irrigated Agriculture: Farm Water Quality Planning Series. This is reference sheet 9.1 in the Farm Water Quality Planning series.
Catalog #8055
Full Title: Practices for Reducing Nonpoint Source Pollution from Irrigated Agriculture: Farm Water Quality Planning Series. This is fact sheet 3.1 in the Farm Water Quality Planning series.
Catalog #8075
Full title: Reducing Runoff from Irrigated Lands: Causes and Management of Runoff from Surface Irrigation in Orchards.
Minimizing runoff from surface irrigation is a balance between adequate irrigation and tailwater runoff. This publication discusses how surface runoff can occur and management methods that can minimize the amount of water leaving a property.
Catalog #8214
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.
Catalog #8194
Full title: Reducing Runoff from Irrigated Lands: Managing Existing Sprinkler Irrigation Systems. If you experience runoff from an existing sprinkler-irrigated orchard, changing the design and set-up of the sprinkler system, the management of the sprinkler system, or the management of the orchard floor may reduce the amount.
Catalog #8215
Minimizing the application of excess water requires knowing when and how much water to apply. Flow measurement is most easily done in a pipeline; this publication describes the four most commonly used flowmeters, their maintenance, and uses.
Catalog #8213
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.
Catalog #8202
Full title: Reducing Runoff from Irrigated Lands: Soil Intake Rates and Application Rates in Sprinkler-Irrigated Orchards. Matching the sprinkler application rate to the soil intake rate is difficult and complex. This publication discusses three approaches to determine the design application rate of a sprinkler irrigation system to the soil intake rate.
Catalog #8216
This publication discusses the variables and feasibility of storage of winter rainwater in order to avoid impact by the Irrigated Lands Conditional Waiver under the California State Water Code.
Catalog #8211
Excess irrigation water that runs off a farm field ("tailwater") is regulated by California law, since it may be carrying sediments, nutrients, and agricultural chemicals. Learn about options for safely recycling tailwater back into your farm operation.
Catalog #8225
Full title: Reducing Runoff from Irrigated Lands: Understanding Your Orchard's Water Requirements. A simple way to determine the proper irrigation amount is to estimate the amount of water the trees have used, evapotranspiration (ET), since the last irrigation. Learn how to easily calculate real-time ET rates using data provided by CIMIS.
Catalog #8212
Nonpoint source (NPS), common in agriculture, reaches the environment as runoff from a field, not output from a waste pipe. Its control and regulation are also different from other types of pollution that may seem more familiar.
Catalog #8203
How to make the most of your lawn area using the least amount of irrigation water.
Catalog #8036
