A model of manure utilization is developed and applied to four types of transportable manure. Model results highlight important response differences among manure types and generally illustrate the diseconomies of manure production. For example, as manure production increases, manure value...

Efficiency in beef production and economics is impacted by cow maintenance requirements and output. Budget and linear programming analysis are used to evaluate cost and returns for two cow sizes on two different pasture systems. Moderate-sized cows on native pasture generate the greatest pre-tax...

With the Water Framework Directive (WFD), the European Union has established a legal framework for the protection of all aquatic ecological systems, including groundwater. This directive may have advantages for the water regime in ecologically sensitive areas but may also bring some economic...

Th is paper presents electronic tool to support farmers in fertilization planning. It is developed as a spreadsheet model, utilizing optimization potential of mathematical programming techniques. Described problem of fertilization planning is rather simple from technological-expert viewpoint,...

The aim of the paper is to develop an optimization model to support the analysis of decision-making on Macedonian family farms. For this purpose, normative linear programming paradigm is applied, utilising its optimization potential. The model is tested and presented on vegetable farm level....

Ireland’s dairy sector is characterised by pastoral spring-calving systems and seasonal milk production at national level. This production seasonality initiates various implications at processor level, such as poor plant capacity utilisation off-peak season or a requirement for seasonal...

‘Farming for Nature’, a relatively new policy instrument being tried out in the Netherlands, is evaluated. The concept has been designed to allow dairy farmers to improve nature conservation on their farms. Under the scheme, no manure, fertilizer, or feed – concentrates or...

This study describes the development of bio economic models examining the economic and water quality impact of various proposed policy options in the Upper Waikato catchment. In the first phase nitrogen emissions are determined for representative farming systems using the Overseer nutrient...

Although a handful of forage species such as perennial ryegrass are predominant, there are a wide range of forage species that can be grown in sub tropical and temperate regions in Australia as dairy pastures. These species have differing seasonal yields, nutrient quality and water use...

Four strategies for farm growth are analyzed and compared on the basis of ownership, equity, and productive capacity achieved, and on the basis of resistance to adversity. The primary tool of analysis was a model utilizing a stochastic simulator interfaced with both ex ante and ex post linear...
