Some Limnological Conditions Relative to Winter Kill of Fish in Ice-Covered Representative Farm Ponds in Eastern South Dakota
An aquatic environment involves many complex relationships biologically, physically, and chemically. Many of these relationships are difficult to measure or are little understood. In nature, aquatic environments accommodate many types of aquatic life. Ecological disturbances may cause the …

A dynamic analysis of the crop productivity impacts of soil erosion: an application to the Piedmont area of Virginia
… the soil resource. In particular, four empirical representative farm models were formulated. Solutions to the four representative farm models showed that sizable reductions in topsoil loss, which contributes to non-point source pollution, and aggravates the crop productivity impacts of soil …

Sustainable development in Honduras: economic evaluation of soil conservation practices
… adoption of soil conservation practices for a representative farm in a watershed in Honduras are examined in a linear programming framework. Special attention is paid to income-soil loss tradeoffs, income-risk tradeoffs, and on the effect of different farmers' planning horizons on net farm …

Stock wintering systems in Southland
… production per animal and per hectare. Several farming systems are explored in this study and linear programming is used to develop an optimal farming system. Farm areas are analysed to expose existing resource restrictions and to define representative farm input levels for use in the linear …

Risk Analysis of Adopting Conservation Practices on a Representative Peanut-Cotton Farm in Virginia
… nitrogen, phosphorus, and sediment losses of a representative risk-neutral and risk-averse peanut-cotton farmer in Southeast Virginia. Five currently popular rotations and eight alternative conservation rotations are evaluated for the representative farm. The Erosion-Productivity Impact …

The economic feasibility of introducing aquaculture into traditional farming systems in Arizona
… fish culture into irrigated cotton production on farms in central Arizona. The representative farm adopted in this study is a cotton farm described in Arizona Field Crop Budgets, 1994-95. The only adjustment necessary for the farmer to make is to keep water in the ditches at all times. Water as a …

An agent-based simulation model of structural change in agriculture
… significant fundamental structural changes in farming. Structural change encompasses evolution in distribution of farm sizes, land tenure and financial characteristics, as well as variations in demographic and production characteristics. These issues are often a source of discontent among farm …

The effect of crop yield and feed price variability on profitability of dairy farming in Virginia: a target MOTAD approach
Dairy farming in Virginia could be more profitable if price and yield risks affecting the cost and availability of feed inputs such as corngrain, corn silage, alfalfa and ryelage are reduced. Price and yield risk facing dairy farmers in Virginia can be reduced through a marketing strategy like …

Food aid and economic development: impact of food for work on labor allocation, production and consumption behavior of small family-farms in a semi-arid area of Kenya
… providing income to ease capital constraints on farm production. However, it was feared that FFW might divert labor from own-farm production and reduce the level of locally produced food crops. The purpose of this dissertation was to empirically examine these hypotheses in the Ewalel and Marigat …
