Nondormant Alfalfa Varieties for Arizona 2017Alfalfa varieties differ in fall dormancy, defined as growth during the fall. Nondormant alfalfa varieties are usually planted in mild winter areas for their ability to grow in the fall. However, fall growth of nondormant alfalfa may be undesirable in areas subject to repeated frosts or freezes. Nondormant, very nondormant, and extremely nondormant alfalfa varieties (fall dormancy class 8, 9, and 10) are adapted to elevations below 4000 feet in Arizona. Other dormancy classes not included in this publication are moderately nondormant varieties (fall dormancy class 7) which may be grown from 3000 to 5000 feet, and semi-dormant and dormant varieties (fall dormancy 6 and below) which are adapted to colder winter areas above 4000 feet.

Eating for Two – A Healthy Pregnancy Starts with a Healthy DietThe saying “you are what you eat” takes on a new meaning when a woman learns she is expecting a baby. For the next several months, her growing baby’s health is directly dependent upon what she eats, and what she chooses to avoid. What is more, a woman’s diet during pregnancy has been shown to affect her child’s health long after she is no longer eating for two.

OsteoporosisOsteoporosis means “porous bones.” It is a condition where the skeleton becomes fragile and results in broken bones under normal use. Osteoporosis is a “silent” condition that happens slowly over years. The rate of bone loss (“resorption”) exceeds the rate of new bone formation (“acretion”). Many times neither a person nor a doctor is aware of weakened bones until one breaks unexpectedly. Originally published: 2000

Human Disease Causing Viruses Vectored by MosquitoesThere are a number of disease-causing viruses transmitted to people primarily through the bite of infected mosquitoes. Female mosquitoes take blood meals to produce eggs. A mosquito that bites an infected animal may pick up a virus within the blood meal. If the mosquito is the appropriate species, and conditions inside the insect and the surrounding environment are supportive, the virus reproduces within the mosquito. Later, the mosquito may pass the virus on to other animals (including humans) as they feed again.

Types of Solar Photovoltaic SystemsSolar energy systems can help Arizona individuals, families, and businesses achieve energy conservation goals beyond the adoption of energy-efficient appliances, and LED bulbs. Which type of system is the best? Knowing which system to select is the first important question. This factsheet will focus on solar photovoltaic energy systems. The term photovoltaic refers to the conversion of light energy to electricity.

A Summary of Livestock Grazing Systems Used on Rangelands in the Western United States and CanadaThe objectives of this article are to provide an overview of the major grazing systems that have been used on rangelands in the western U. S. and Canada, to summarize the conditions under which they may be applicable, and to highlight examples from the southwestern U. S. when relevant. Revised 12/2014. Originally published 09/2000.

Planting Pole Cuttings in Riparian EcosystemsRiparian ecosystems are found in the transition between aquatic and adjacent terrestrial ecosystems where unique vegetative communities can occur due to free water at or near the soil surface. A healthy, functional riparian plant community provides a rich environment for insects, mollusks, amphibians, reptiles, fishes, birds, and animals. In Arizona, many naturally occurring riparian ecosystems have been impacted, altered or removed by natural processes and land management activities. This publication provides information to assist residents, landowners, and agency personnel in successfully establishing pole plantings in riparian ecosystems of Arizona.

Invasive Plants on Small Acreage Properties in ArizonaInvasive plants are plants that have been accidentally or intentionally introduced to an area outside their original range and become problematic in their new environment by interfering with native or desirable species. Landowners can help prevent the spread and assist in controlling these invasive plants. Revised 11/2016. Originally published 01/2010.

Using Repeat Color Photography as a Tool to Monitor RangelandsThis article provides an introduction to repeat color photography and explains how it can be used as an important part of a comprehensive rangeland monitoring program. Reviewed 12/2014. Originally published 05/1998.

Rangeland Management Before, During and After DroughtRangeland and livestock management in the southwestern U.S. presents many formidable challenges. Environmental regulations, cattle prices, and drought are just a few factors that contribute to the management challenges of the range-livestock industry. Among them, drought may be the least controllable or predictable variable. This publication discusses how to prepare for drought in southwestern U.S. Topics include principles of drought and range-livestock management, management before drought, management during drought and management after drought.

Non-Native Invasive Plants of ArizonaThe noxious weed problem in the western United States has been described as, a biological forest fire racing beyond control because no one wants to be fire boss. Indeed, when small weed infestations are left unchecked, they can grow exponentially and spread across the land much like a slow-moving biological wildfire. However, land consumed by fire usually recovers and is often more productive than before the fire occurred. On the other hand, land consumed by noxious weeds may be irreversibly changed and never again reach its full biological potential. Reviewed 12/2016, First Edition Published 2001

How Do Domestic Herbivores Select Nutritious Diets on Rangelands?Animal learning has been shown to play a major role in the development of diet selection by domestic herbivores. Dr. Frederick Provenza and his associates at Utah State University have conducted a series of studies over the past 30 years to learn how physiological and behavioral mechanisms govern diet selection. In this paper, we synthesize several key diet selection concepts presented in 4 articles (i.e., Provenza et al. 1992; Provenza 1995, 1996, 1997). Reviewed 12/2014; originally published 05/1998.

Growing Grain Sorghum in ArizonaProduction practices for grain sorghum are discussed including hybrid selection, planting date, seeding rate, row configuration, irrigation, fertilization, pest control, and harvesting. Grain sorghum (milo) is a warm season, annual grain crop. It is more resistant to salt, drought, and heat stress than most other crops. Nevertheless, highest yields are obtained when stresses are minimized. Revised 10/2016. Originally published 06/2009.

Principles of Obtaining and Interpreting Utilization Data on RangelandsA primary expression of stocking levels on rangeland vegetation is utilization defined as the proportion or degree of current years forage production that is consumed or destroyed by animals (including insects). Utilization may refer either to a single plant species, a group of species, or the vegetation as a whole. Utilization is an important factor in influencing changes in the soil, water, animal, and vegetation resources. The impact of a specific intensity of use on a plant species is highly variable depending on past and present use, period of use, duration of use, inter-specific competition, weather, availability of soil moisture for regrowth, and how these factors interact. Utilization data can be used as a guideline for moving livestock within an allotment with due consideration to season, weather conditions and the availability of forage and water in pastures scheduled for use during the same grazing season. In combination with actual use and climatic data, utilization measurements on key areas and utilization pattern mapping are useful for estimating proper stocking levels under current management. Utilization studies are helpful in identifying key and problem areas, and in identifying range improvements needed to improve livestock distribution. Reviewed 10/2016. Originally published 5/2007.
