Liebig's law of the minimum, often simply called Liebig's law or the law of the minimum, is a principle developed in agricultural science by Carl Sprengel (1840) and later popularized by Justus von Liebig. It states that growth is dictated not by total resources available, but by the scarcest resource (limiting factor).
Limiting factor is a concept in ecology that describes the condition that restricts the growth or survival of a population or an ecosystem.
Blackman's law is illustrated by concentration as a limiting factor in the rate of oxygen production in photosynthesis: Suppose a leaf is exposed to a certain light intensity which can use 5 mg. of per hour in photosynthesis. If only 1 mg. of enters the leaf in an hour, the rate of photosynthesis is limited due to factor.
Law of Maximum. The Law of Maximum also known as Law of the Maximum is a principle developed by Arthur Wallace which states that total growth of a crop or a plant is proportional to about 70 growth factors. Growth will not be greater than the aggregate values of the growth factors. Without the correction of the limiting growth factors ...
Phosphorus is the limiting factor for plant growth in most freshwater ecosystems, [15] and because phosphate adheres tightly to soil particles and sinks in areas such as wetlands and lakes, [16] due to its prevalence nowadays more and more phosphorus is accumulating inside freshwater bodies. [17][18] In marine ecosystems, nitrogen is the ...
Plant nutrition. Plant nutrition is the study of the chemical elements and compounds necessary for plant growth and reproduction, plant metabolism and their external supply. In its absence the plant is unable to complete a normal life cycle, or that the element is part of some essential plant constituent or metabolite.
Shelford's law of tolerance. Shelford's law of tolerance is a principle developed by American zoologist Victor Ernest Shelford in 1911. It states that an organism 's success is based on a complex set of conditions and that each organism has a certain minimum, maximum, and optimum environmental factor or combination of factors that determine ...
The factors limiting primary production in the ocean are also very different from those on land. The availability of water, obviously, is not an issue (though its salinity can be).
