By Francis J. Pierce, David Clay

The elevated potency and profitability that the correct software of know-how delivers has made precision agriculture the most well liked constructing region inside conventional agriculture. the 1st single-source quantity to hide GIS purposes in agronomy, GIS purposes in Agriculture examines ways in which this strong expertise may help farmers produce a better abundance of vegetation with extra potency and at reduce expenses.

Each bankruptcy describes the character of an issue, examines the aim and scope of a GIS program, offers the tools used to improve the applying, after which is going directly to offer effects and supply a end in addition to helping details. while applicable, the chapters current the underlying statistical strategy for the GIS software program that's used.  appropriate facts units and colour maps produced via use of GIS are integrated for obtain on the CRC webiste.

Concentrating extra at the procedure and not more at the particular software program, the authors describe the equipment used to improve an program and speak about barriers to the algorithms and the programming code used. They then summarize the appliance by way of what it does, the way it works, its obstacles, and its capability makes use of. The publication presents a toolkit for the purchase, administration, and research of spatial info through the agriculture price chain.

2 Nitrogen Management in Sugar Beet Using Remote Sensing and GIS David W. 1 EXECUTIVE SUMMARY One of the most successful early applications of remote sensing and geographic information systems (GIS) in agriculture has been in improving sugar beet (Beta vulgaris) nitrogen management. Sugar beet is a crop that leaves much of the nitrogen it takes up during the growing season in the field at harvest. A portion of that nitrogen can be credited against the supplemental fertilizer nitrogen required by the following crop.

12. , personal communication, 2004. 3 Using Historical Management to Reduce Soil Sampling Errors David E. Clay, N. Kitchen, C. 1 EXECUTIVE SUMMARY Many of the small farms that dotted the countryside a hundred years ago had enclosures where horses, cows, and hogs were kept. The remnants from these enclosures impact soil properties today. Management that occurred on these farms 50 or even 100 years ago influences our ability to collect representative soil samples. Aerial photographs stored by USDA Farm Services Agronomy offices provide clues to past management.
