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 Precision, Geospatial, & Sensor Technologies http://www.pubs.ext.vt.edu/3006/3006-1454/3006-1454.html Wed, 16 Jun 2010 15:09:13 -0400 http://www.pubs.ext.vt.edu/3006/3006-1454/3006-1454.html Machinery Economics http://www.pubs.ext.vt.edu/448/448-076/448-076.html <p>The price of GPS (Global Positioning Satellite) guidance system technology continues to decline as its capabilities increase. Many farmers question if or when they should invest in this technology. The major advantage of using GPS is input savings from more precise field application of seed, fertilizers, chemicals, fuel, and labor, as well as increased benefits to the farm production process (extended working time, reduced fatigue, etc.).</p> Tue, 26 May 2009 10:59:30 -0400 http://www.pubs.ext.vt.edu/448/448-076/448-076.html Agricultural Financial Mgmt.

However, there are many field operations (such as light tillage, planting, cultivating, and hay raking) that do not require full tractor power. This is especially true when older implements, which were sized for a smaller tractor, are used with higher horsepower tractors. Also, many operations should be performed at a fixed field speed.</p></div> Fri, 01 May 2009 01:00:00 -0400 http://www.pubs.ext.vt.edu/442/442-450/442-450.html Energy Machinery Economics http://www.pubs.ext.vt.edu/442/442-092/442-092.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>Machines; no farm or ranch can function without them.

The key to safe and efficient systems for handling large round bales is an operator who knows the hazards involved and who follows safety practices that can prevent accidents. Operators must be constantly alert for situations that may cause injuries to themselves or others. Besides pain and suffering, accidents contribute to higher costs in terms of unnecessary downtime or costly machine repairs. Alertness and safety consciousness can result in more efficient and profitable baling and handling.</p> Fri, 01 May 2009 01:00:00 -0400 http://www.pubs.ext.vt.edu/442/442-455/442-455.html Farm Health & Safety Pasture & Forage - Crops & Soils Pasture & Forage - Animal Agriculture Machinery Economics http://www.pubs.ext.vt.edu/442/442-454/442-454.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>This Extension publication discusses management of hay harvesting with a large round baler.

Utilizing pasture as a major portion of the forage plan can significantly reduce feed costs during the grazing season. Virginia's soils and climate are especially favorable for the growth of a wide range of productive, high-quality grasses and legumes suitable for grazing. However, optimizing a controlled grazing system requires careful planning and good management of a fencing system.</p> Fri, 01 May 2009 01:00:00 -0400 http://www.pubs.ext.vt.edu/442/442-130/442-130.html Machinery Economics Pasture & Forage - Crops & Soils Pasture & Forage - Animal Agriculture
