The Phosphorus Cycle01:21

The Phosphorus Cycle

43.9K
Unlike carbon, water, and nitrogen, phosphorus is not present in the atmosphere as a gas. Instead, most phosphorus in the ecosystem exists as compounds, such as phosphate ions (PO43-), found in soil, water, sediment and rocks. Phosphorus is often a limiting nutrient (i.e., in short supply). Consequently, phosphorus is added to most agricultural fertilizers, which can cause environmental problems related to runoff in aquatic ecosystems.

How Data are Classified: Categorical Data

44.6K
A variable, usually notated by capital letters such as X and Y, is a characteristic or measurement that can be determined for each member of a population. Data are the actual values of variables. They may be numbers, or they may be words. Datum is a single value.
Data are classified based on whether they are measurable or not. Categorical data cannot be measured; instead, it can be divided into categories. For example, if Y denotes a person's party affiliation, some examples of Y include...

Chirality at Nitrogen, Phosphorus, and Sulfur02:30

Chirality at Nitrogen, Phosphorus, and Sulfur

7.0K
Chirality is most prevalent in carbon-based tetrahedral compounds, but this important facet of molecular symmetry extends to sp3-hybridized nitrogen, phosphorus and sulfur centers, including trivalent molecules with lone pairs. Here, the lone pair behaves as a functional group in addition to the other three substituents to form an analogous tetrahedral center that can be chiral.
A consequence of chirality is the need for enantiomeric resolution. While this is theoretically possible for all...

Production Efficiency01:01

Production Efficiency

18.3K
Net production efficiency (NPE) is the efficiency at which organisms assimilate energy into biomass for the next trophic level. Due to low metabolic rates and less energy spent on thermoregulatory processes, the NPE of ectotherms (cold-blooded animals) is 10 times higher than endotherms (warm-blooded animals).

Trophic Efficiency00:46

Trophic Efficiency

25.2K
Trophic level transfer efficiency (TLTE) is a measure of the total energy transfer from one trophic level to the next. Due to extensive energy loss as metabolic heat, an average of only 10% of the original energy obtained is passed on to the next level. This pattern of energy loss severely limits the possible number of trophic levels in a food chain.

Efficiency of The Carnot Cycle01:16

Efficiency of The Carnot Cycle

3.7K
The hypothetical Carnot cycle consists of an ideal gas subjected to two isothermal and two adiabatic processes. Since the internal energy of an ideal gas depends only on its temperature, which is the same before and after the completion of the Carnot cycle, there is no change in its internal energy. Hence, using the first law of thermodynamics, the total heat exchanged by the ideal gas equals the total work done. Thus, we can quantify the efficiency of the Carnot cycle via the heat exchanged...

Area of Science:

  • Agricultural Science
  • Plant Breeding
  • Nutrient Management

Background:

  • Phosphorus (P) is vital for plant growth, but its availability is limited, impacting crop yields.
  • Developing phosphorus-efficient crop cultivars enhances food productivity and minimizes environmental pollution from P runoff.
  • Categorizing existing germplasm is essential for identifying and breeding P-efficient crop varieties.

Purpose of the Study:

  • To evaluate and categorize wheat genotypes for phosphorus (P) efficiency under varying P supply conditions.
  • To identify superior P-efficient wheat genotypes for future breeding programs.
  • To determine the most effective method for categorizing P-efficiency in wheat germplasm.

Main Methods:

  • Two experiments were conducted: hydroponics with deficit (20 μm KH2PO4) and adequate (200 μm KH2PO4) P levels, followed by soil trials with 0 and 30 mg P kg-1.
  • Thirty wheat genotypes were screened in hydroponics, and twelve selected genotypes were evaluated in soil until maturity.
  • Genotypes were assessed for P-efficiency parameters, including growth, dry matter production, and grain yield, and categorized using established methods.

Main Results:

  • Significant genotypic differences in P-efficiency parameters were observed under both hydroponic and soil conditions.
  • Genotypes Dirk and Bhakkar-02 showed minimal growth reduction (<25%) under P deficiency, while Seher-06 was inefficient.
  • The categorization method proposed by Gill et al. (3 classes, plotted into 9) effectively differentiated minor variations in P-efficiency among genotypes.

Conclusions:

  • Genotype Dirk demonstrated superior P-efficiency based on dry matter production under both P regimes.
  • The Gill et al. categorization method is recommended for its ability to discern subtle differences in P-efficiency.
  • Utilizing at least three P-efficiency parameters across both P-deficient and adequate conditions is crucial for accurate genotype assessment.
