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.

In nature, diatoms frequently grow under nutrients limiting conditions and although nitrogen and iron have been reported as limiting nutrients; there is also evidence of phosphorus limitation (Girault et al., 2013).

In this study, one can speculate that boron is a possible candidate to main limiting nutrient for these Cerrado native grasses, since it was the only nutrient that had its concentration increased in area 2 due to dung addition.

N:P ratios ranged from 130:1 in Copacabana Bay, 124:1 in Cohana Bay, 110:1 in Tiquina, to 79:1 in Alaya, showing clearly that phosphorus is the limiting nutrient in all cases.

It also affects ocean chemistry, acting as a major source of iron, which is often a limiting nutrient for plankton and other organisms.

In crop production, Liebig's law of minimum (Y = kX up to a plateau) and Mitscherlich's law of diminishing returns (Y = A[1 - [e.sup.kX]]) are well known response models to X, the growth limiting nutrient, where Y is crop yield, A is maximum yield, and k is a proportionality constant (Trionfo, 2000).

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. By applying based on the limiting nutrient, we minimize the potential for over applying either nitrogen or phosphorus, both of which can cause over fertilization of lakes and bays leading to algae blooms.

Minimizing your environmental impact

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. However, where the combination of nitrogen and phosphorous supply to waterways is very high, as in rich agricultural areas, the receiving rivers, lakes, and estuaries exhibit extreme eutrophication.

A nitrogen fixation

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.
