Many of these questions are economic, some are agronomic and environmental, and others are technology-related. This publication is intended to discuss variable-rate devices that are available, while providing an understanding of which technologies might best fit a cropping system and production management strategy.</p> Mon, 01 Aug 2011 14:44:14 -0400 http://www.pubs.ext.vt.edu/442/442-505/442-505.html Equipment & Structures Machinery Economics Tools & Techniques http://www.pubs.ext.vt.edu/442/442-073/442-073.html Tue, 24 Aug 2010 11:47:38 -0400 http://www.pubs.ext.vt.edu/442/442-073/442-073.html Energy Equipment & Structures Farm Business Mgmt. & Planning http://www.pubs.ext.vt.edu/442/442-084/442-084.html <p>In terms of work-related injuries, farming remains one of the most dangerous occupations in the United States. In 2007, national statistics showed 411 fatalities – 23.5 deaths per 100,000 farm workers – from accidents resulting from agriculture-related activities (NIOSH 2009). Statistics also reveal that agriculture-related activities result in nonfatal injuries. For example, in 2006, crop and animal-production activities resulted in 22,400 and 13,100 injuries, respectively (U.S. Department of Labor 2006). These nonfatal injuries may include primary as well as secondary injuries.</p> Thu, 01 Jul 2010 15:09:14 -0400 http://www.pubs.ext.vt.edu/442/442-084/442-084.html Equipment & Structures Farm Health & Safety http://www.pubs.ext.vt.edu/442/442-309/442-309.html Thu, 01 Apr 2010 08:30:09 -0400 http://www.pubs.ext.vt.edu/442/442-309/442-309.html Beef Cattle Dairy Cattle Environmental Quality Equipment & Structures Natural Resources & Environmental Quality Poultry Sheep & Goats Swine http://www.pubs.ext.vt.edu/444/444-500/444-500.html Fri, 05 Mar 2010 10:32:26 -0500 http://www.pubs.ext.vt.edu/444/444-500/444-500.html Equipment & Structures Home Pests http://www.pubs.ext.vt.edu/444/444-502/444-502.html Fri, 05 Mar 2010 10:12:13 -0500 http://www.pubs.ext.vt.edu/444/444-502/444-502.html Equipment & Structures Home Pests http://www.pubs.ext.vt.edu/444/444-501/444-501.html Mon, 01 Mar 2010 10:22:55 -0500 http://www.pubs.ext.vt.edu/444/444-501/444-501.html Equipment & Structures Home Pests http://www.pubs.ext.vt.edu/418/418-121/418-121.html <div xmlns:o="urn:www.microsoft.com/office" xmlns:st1="urn:www.microsoft.com/smarttags" xmlns:st2="urn:www.microsoft.com/smarttags2" xmlns:w="urn:www.microsoft.com/word" xmlns:x="urn:www.microsoft.com/excel"><p>Successful forage establishment requires that seed be planted at the recommended density. Planting lower than the required rate will result in thin stands with increased weed problems and lower yields. On the other hand, planting at a higher than recommended seed rate will significantly increase seeding costs. Calibration becomes more important as the cost of the seed increases.</p><p>Calibration charts can be found on most seeding equipment and they provide a good starting point. However, variations in seed size, weight, purity, and coatings, and performance of seeding equipment can cause large discrepancies between chart settings and actual seeding rates. Therefore, it is critical to know how much seed is actually being metered out for any given combination of variety, seeder, and field condition.</p></div> Thu, 10 Dec 2009 09:04:43 -0500 http://www.pubs.ext.vt.edu/418/418-121/418-121.html Equipment & Structures Pasture & Forage - Animal Agriculture Pasture & Forage - Crops & Soils http://www.pubs.ext.vt.edu/442/442-308/442-308.html Thu, 19 Nov 2009 10:43:36 -0500 http://www.pubs.ext.vt.edu/442/442-308/442-308.html Beef Cattle Dairy Cattle Environmental Quality Equipment & Structures Natural Resources & Environmental Quality Poultry Sheep & Goats Swine http://www.pubs.ext.vt.edu/442/442-307/442-307.html <p>If you raise dairy cows, broilers, layers, turkeys, horses, beef cattle, sheep, goats, alpacas, or swine for income or a hobby, you will have to deal with the manure they produce.

Off-target movement in the form of spray drift is a major concern because it diverts the chemical from the intended target, reduces efficacy, and deposits pesticide where it is not needed or wanted. When a pesticide drifts, it may cause both environmental and economic damage, including exposure to people and property, injury to susceptible vegetation, harm to wildlife, deposition of illegal residues on crops, and contamination of water supplies.</p> Wed, 27 May 2009 09:19:39 -0400 http://www.pubs.ext.vt.edu/442/442-031/442-031.html Agricultural Insects / Pests Equipment & Structures Pesticide Education http://www.pubs.ext.vt.edu/442/442-032/442-032.html <p>This fact sheet covers nozzle description, recommended use for common nozzle types, and orifice sizing for agricultural and turf sprayers.

However, as animal production shifts toward fewer but larger operations, the number of confined animals has increased in some geographical locations, resulting in more manure produced than can be assimilated by the available farmland where the animals are raised.

Virginia producers who have restricted or eliminated livestock access to streams and farm ponds and converted to a clean, alternative water source have observed increased livestock productivity, improved water quality, and restored stream banks on their farms. As a consequence, livestock stream exclusion practices are gaining popularity across Virginia. This publication, produced through the cooperation of Virginia Cooperative Extension and the Virginia Department of Conservation and Recreation, describes the findings, experiences, and successes of individual producers who are limiting livestock stream access.</p> Fri, 01 May 2009 01:00:00 -0400 http://www.pubs.ext.vt.edu/442/442-766/442-766.html Equipment & Structures Environmental Quality Natural Resources http://www.pubs.ext.vt.edu/442/442-763/442-763.html <p>Ventilation systems in dairy barns help maintain a comfortable environment to keep cows healthy and productive. Cows continuously produce heat and moisture. Therefore, a ventilation system is necessary to constantly exchange warm, humid air inside the barn for cooler, drier air outside of the barn. This exchange must occur regardless of outside temperature or weather conditions. Fresh outside air is required even on a cold, windy night to reduce moisture accumulation inside the barn. Good air exchange also removes nuisance odors and manure gases that can have negative effects on animal health and performance.</p> Fri, 01 May 2009 01:00:00 -0400 http://www.pubs.ext.vt.edu/442/442-763/442-763.html Equipment & Structures http://www.pubs.ext.vt.edu/442/442-762/442-762.html <p>Post-frame buildings have been popular in the agricultural community for over fifty years. However, many agricultural producers do not have the resources to design and construct post-frame buildings and should rely on a contractor to do this work for them. The challenge for the producer is to select a contractor who will incorporate adequate materials with well-engineered designs to construct a structurally sound and functional building.

The building can be used to store hay, machinery, or both. As a result, the value of these commodities will be worth more than if left in the field. However, does the increased value of stored hay or machinery offset the cost of owning a building? The following discussion examines the costs and savings of owning a farm storage building.</p> Fri, 01 May 2009 01:00:00 -0400 http://www.pubs.ext.vt.edu/442/442-760/442-760.html Equipment & Structures http://www.pubs.ext.vt.edu/442/442-757/442-757.html <p>Micro-irrigation systems can deliver water and nutrients in precise amounts and at controlled frequencies directly to the plant's root zone. With micro-irrigation systems, an extensive network of pipe is used to distribute water to emitters that discharge it in droplets, small streams, or through mini-sprayers. The major cause of failure in micro-irrigation systems is emitter plugging. Emitter plugging can severely degrade irrigation system performance and application uniformity. Because the emitters are small and can easily plug, it is important to understand the filtration and maintenance requirements of these systems and be proactive to prevent plugging. The basic components of a typical micro-irrigation system are shown in Figure 1.</p> Fri, 01 May 2009 01:00:00 -0400 http://www.pubs.ext.vt.edu/442/442-757/442-757.html Equipment & Structures http://www.pubs.ext.vt.edu/442/442-755/442-755.html <p>Both intensive grazing and water quality protection programs are increasing the need for pumping water to livestock from locations where commercial electricity is not readily available. If electricity is available, it will generally be the most cost-effective method for pumping water. However, there may be instances where the distance from existing power lines to the desired pump location makes it cost-prohibitive to obtain electricity from the utility. A rule of thumb is that alternative energy sources may be economically justified if the distance to commercial power exceeds one-third of a mile. In this case, the livestock producer can select from a range of alternative power methods. The "best" alternative power option is generally site specific.</p> Fri, 01 May 2009 01:00:00 -0400 http://www.pubs.ext.vt.edu/442/442-755/442-755.html Equipment & Structures http://www.pubs.ext.vt.edu/442/442-457/442-457.html <p>No-till planters and drills must be able to cut and handle residue, penetrate the soil to the proper seeding depth, and establish good seed-to-soil contact.
