Fig. 51 Limiting factor. Contributions and constraints.

limiting factor

key factor

the critical constraint upon a firm's budgeted activity level. In most circumstances the limiting factor will be the amounts that the company can sell, but in certain cases the limiting factor might be shortage of production capacity, shortages of particular raw materials or the like. Here planning will be aimed at devising a sales programme which generates maximum profit from these limited resources. For example, Fig. 51 shows how a firm with limited production capacity might seek to maximize its CONTRIBUTION by concentrating upon production of the product which requires fewer direct labour hours to make. See BUDGET, BUDGETING, LINEAR PROGRAMMING.

When land applying manures and composts you also should calculate the phosphorus requirements of the crop, and land application rates should be calculated based upon the most limiting nutrient.

The objective of this study, therefore, was to identify the most limiting nutrient to production of the crop as the strategic entry point to effective management and subsequent formulation of rationalized packages.

In most aquatic systems it is found to be either phosphorous or nitrogen that is the limiting nutrient.

Growth experiments at different combinations of N and P concentration and analyses of internal plant N and P concentration allow us to determine if mosses are N- or P-limited and to determine the internal plant concentration of the limiting nutrient that is critical to achieve the maximum growth rate.

However, analyses of total nitrogen (TN) and total phosphorus (TP), the key parameters to determine the trophic status and the limiting nutrient that controls algal growth, were not included.

Therefore, the objectives of this project were to 1) determine which nutrient was in limitation across the thermal gradient and 2) determine if the natural phytoplankton assemblages at three points along the gradient differed with respect to uptake rate of the limiting nutrient.
