Ec02-178 Precision Agriculture: On-The-Go Vehicle-Based Soil Sensors, Viacheslav I. Adamchuk, Paul J. Jasa

Historical Materials from University of Nebraska-Lincoln Extension

Imagine that you are entering an unknown field and would like to estimate the productivity of the unfamiliar soil. You may pick up a handful of soil to evaluate its color and texture. You also can feel how difficult it is to break a clod apart, roll it into a ball or press out a ribbon. After repeating this procedure at different field locations, soil depths and times, you get a feeling of both spatial and temporal soil variability. Some of this variability can explain the non-uniformity of crop yield. If you collect soil samples and send them to a ...


Air Sampling With Solid Phase Microextraction, Jacek A. Koziel, Fabio Augusto, Janusz Pawliszyn Jan 2001

Air Sampling With Solid Phase Microextraction, Jacek A. Koziel, Fabio Augusto, Janusz Pawliszyn

Jacek A. Koziel

Solid phase microextraction (SPME) presents many advantages over conventional analytical methods by combining sampling, pre-concentration and direct transfer of the VOCs into a standard gas chromatography (GC) system. Since its introduction SPME has been applied to the sampling and analysis of environmental samples including airborne VOCs and particulates. The first part of this paper presents theory of air sampling with SPME and an overview of the a few current methods for quantitative air sampling and VOC determination with SPME using grab (‘instantaneous”) and time-weighted average (TWA) modes. The second part of this paper is focused on the recent development of ...

Two-Factor Agricultural Experiment With Repeated Measures On One Factor In A Complete Randomized Design, Armando Garsd, María Del C. Fabrizio, María V. López Apr 1995

Two-Factor Agricultural Experiment With Repeated Measures On One Factor In A Complete Randomized Design, Armando Garsd, María Del C. Fabrizio, María V. López

Conference on Applied Statistics in Agriculture

A typical agricultural experiment involves comparisons of several treatments at different points in time. The ensuing lack of independence between observations of the same experimental unit may then impair the attainment of statistical significance by the standard analysis of variance, and calls for the application of more powerful methods. This paper addresses one such method, the so-called two-factor experiment with repeated measures on one factor. We discuss the adequacy of this model in the context of three concrete examples drawn from agricultural experimentation.

G91-1056 Support And Resistance Areas, And Will The Market Give Us A Second Chance?, Lynn H. Lutgen

Historical Materials from University of Nebraska-Lincoln Extension

This is the sixth of nine NebGuides designed to aid producers in starting to use technical analysis in their marketing plan.

Among the most frustrating aspects of marketing are missed opportunities for good prices. These occur because producers becoming overly optimistic. This optimism stems from the belief that a bull market will keep going up.

Ultimately, the market does change direction -- it does so many times before the producer has priced his crop. This NebGuide examines where to draw additional support and resistance lines beyond the support and resistance trend lines explained in the second NebGuide in this series. Some ...


G91-1055 Using Moving Averages To Effectively Analyze Trends, Robin R. Riley, Lynn H. Lutgen Jan 1991

G91-1055 Using Moving Averages To Effectively Analyze Trends, Robin R. Riley, Lynn H. Lutgen

Historical Materials from University of Nebraska-Lincoln Extension

This fifth of a nine NebGuide series is designed to show how trend lines can assist producers and others in analyzing the market's technical side.

What is the objective in using moving averages?

Technical analysts construct a moving average of price to provide a better market timing indicator than the traditional straight-line method. The idea is to smooth out daily price fluctuation to get a clear view of the market trend. The moving average is a method for averaging near-term prices in relation to long-term prices. This technique should not be confused with the oscillators described in NebGuide No ...


G91-1053 Looking For Buy And Sell Signals From Charts, Lynn H. Lutgen Jan 1991

G91-1053 Looking For Buy And Sell Signals From Charts, Lynn H. Lutgen

Historical Materials from University of Nebraska-Lincoln Extension

The third in a series of nine on the basics of technical analysis, this NebGuide explains what to look for in commodity charts.

Producers always look for the ultimate: ever-accurate, foolproof, technical signals to tell what moves to make in the market. The problem is the markets are an ever-changing phenomenon; no one signal can predict prices with 100 percent accuracy.

This NebGuide is design to give readers a feel for different kinds of tecnical signals analysts look for to determine market direction. Major signals discussed are: key reversals, double and triple bottoms, head and shoulders (top and bottom), and ...


G87-828 Growing Perennials, Don Steinegger, Anne Streich Jan 1987

G87-828 Growing Perennials, Don Steinegger, Anne Streich

Historical Materials from University of Nebraska-Lincoln Extension

Planning, soil preparation, and maintenance are necessary in growing a perennial garden of color and interest throughout the growing season.

Herbaceous perennials are non-woody plants that live two or more years under local conditions. The above ground parts of these plants are generally killed to the ground by frost in the fall, but the roots and/or underground parts live through the winter. Growth is renewed and the cycle begins anew in the spring.

While perennials do not require yearly replanting, they still require regular maintenance. For best results, a proper site analysis, soil preparation and routine maintenance are necessary ...


An Economic Analysis Of Food Policy In The Ivory Coast, Yao Prao Felix May 1984

An Economic Analysis Of Food Policy In The Ivory Coast, Yao Prao Felix

All Graduate Theses and Dissertations

Ivory Coast covers an area of 124,000 square miles with reasonable rainfall for food crops production. But besides what has been called the economic "miracle," the country relies on increasing food imports (rice, wheat, meat, and milk products). At the same time, the country's earnings from the major export commodities are shrinking. So the primary objective was to identify the main causes and circumstances that have resulted in reductions in food production. The major hypothesis was that the present situation is simply the result of policies that have favored cash crops relative to good products. A formal treatment ...

Analysis And Testing Of Powered Tillage Blades, Larry G. Wells, E. M. Smith, D. E. Hammett Jan 1980

Analysis And Testing Of Powered Tillage Blades, Larry G. Wells, E. M. Smith, D. E. Hammett

Biosystems and Agricultural Engineering Faculty Publications

Fundamental design considerations for powered rotary tillage blades are presented and discussed. The relationship between blade angular velocity and the geometric dimensions of cutting edges is specified for tillage blades rotating counter to the direction of travel and assuming a typical forward speed for tillage.

Analyses showed that a powered blade rotated opposite to the direction of travel can be operated at relatively lower angular velocities than can one rotated in the direction of travel to achieve equivalent blade velocity and acceleration relative to the soil. Furthermore, a blade rotated opposite to the direction of travel requires relatively lower power ...

Rb246 Trees And Shrubs For Noise Abatement, David I. Cook, David F. Van Haverbeke

Historical Materials from University of Nebraska-Lincoln Extension

Excessive noise is a form of environmental pollution. The continual increase in the community noise level during the past two decades indicates a future noise problem comparable to the current air pollution problem of our large industrial centers.

Trees and other forms of vegetation are known to have some effect on the transmission of sound but precise information on their use as noise screens is rather meager. In this study, we attempted to derive accurate, useful information for the above purpose, and to add to knowledge about outdoor sound propagation. Actual plantings of trees and shrubs in the form of ...
