Data in Brief
|August 28, 2019
Summary
This study quantifies phosphorus in US crop production and agricultural inputs, including phosphorus use efficiency (PUE) and Net Anthropogenic Phosphorus Input (NAPI) from 1987-2012. The findings provide crucial data for understanding regional phosphorus dynamics and management.
Area of Science:
- Agricultural Science
- Environmental Science
- Soil Science
Background:
- Phosphorus is a critical nutrient for crop production but its excessive input can lead to environmental issues.
- Understanding agricultural phosphorus dynamics is essential for sustainable agriculture and environmental protection.
- Estimates of phosphorus use efficiency (PUE) and Net Anthropogenic Phosphorus Input (NAPI) are vital for assessing agricultural impacts.
Purpose of the Study:
- To estimate phosphorus content in crop production across the contiguous United States.
- To calculate phosphorus use efficiency (PUE) and agricultural phosphorus inputs.
- To provide Net Anthropogenic Phosphorus Input (NAPI) estimates and related data at multiple scales.
Main Methods:
- Data were derived from USDA agricultural census and US population census data.
- Estimates were calculated using version 3.1 of the NANI/NAPI calculator toolbox.
- Data were analyzed for 6 agricultural census years between 1987 and 2012.
Main Results:
- Estimates of phosphorus content, PUE, and agricultural phosphorus inputs are provided for county, sub-regional, and regional scales.
- Net Anthropogenic Phosphorus Input (NAPI) data are presented for the contiguous United States.
- The data cover the period from 1987 to 2012, reflecting changes in phosphorus management.
Conclusions:
- The study provides comprehensive data on agricultural phosphorus dynamics in the US.
- These estimates are valuable for researchers, policymakers, and stakeholders involved in phosphorus management.
- The data can inform strategies for improving phosphorus use efficiency and mitigating environmental risks.

02:30Chirality at Nitrogen, Phosphorus, and Sulfur
6.8K
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...

01:21The Phosphorus Cycle
43.7K
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.

01:49The Nitrogen Cycle
59.6K
Nitrogen atoms, present in all proteins and DNA, are recycled between abiotic and biotic components of the ecosystem. However, the primary form of nitrogen on Earth is nitrogen gas, which cannot be used by most animals and plants. Thus, nitrogen gas must first be converted into a usable form by nitrogen-fixing bacteria before it can be cycled through other living organisms. The use of nitrogen-containing fertilizers and animal waste products in human agriculture has greatly influenced the...

01:20Overview of Nitrogen Metabolism
11.0K
Nitrogen is a very important element for life because it is a major constituent of proteins and nucleic acids. It is a macronutrient, and in nature, it is recycled from organic compounds and stored in the form of ammonia, ammonium ions, nitrate, nitrite, or nitrogen gas by many metabolic processes. Many of these metabolic processes are carried out only by prokaryotes.

489
Nitrogen is an essential element in biological systems, forming a crucial component of proteins, nucleic acids, and other cellular constituents. Many bacteria and archaea acquire nitrogen in the form of nitrate (NO₃⁻) or ammonia (NH₃), which are then assimilated into biomolecules through specific enzymatic pathways.Assimilatory Nitrate ReductionWhen nitrate enters the cell, it undergoes a two-step reduction process known as assimilatory nitrate reduction. Initially, the enzyme...

01:03IR Frequency Region: Fingerprint Region
1.9K
IR spectra are divided into two main regions: the diagnostic region and the fingerprint region. The diagnostic region of the spectrum lies above 1500 cm−1. The absorptions resulting from single-bond vibrations of the N–H, C–H, and O–H stretch at higher wavenumbers and appear on the left side of the spectrum. The stretching absorptions of the C≡C and C≡N occur between 2100–2300 cm−1. In contrast, those arising from stretching absorptions of the...
