Data from: Plant, grain, and soil response of irrigated malt barley as affected by cultivar, phosphorus, and sulfur applications on an alkaline soil
This study investigated the effects of cultivar and fertilizer phosphorus and sulfur applications on two-row malt barley (Hordeum vulgare L.) grown in alkaline soil. The study took place at the Aberdeen Research and Extension Center, University of Idaho (42.95, -112.83) during the 2015 and 2016 growing seasons.
A Survey to Evaluate the Current Status of Land Grant University and State Department of Agriculture Soil Fertility Recommendations and Analytical Methods
Results of a survey to collect contemporary information from our land-grant university colleagues working in soil fertility. The goals of the survey were to gain a better understanding of the current status of soil testing across the U.S. to inform future collaborative efforts among states and regions, and to identify where opportunities exist to harmonize recommendation guidelines. The objectives were to collect information about state soil test recommendations, fertilization philosophy, analytical methods, and the provenance of correlation and calibration data that support soil-test-based recommendations.
Data from: Chapter 5: Energy Use in Agriculture. U.S. Agriculture and Forestry Greenhouse Gas Inventory: 1990-2018
The report 'U.S. Agriculture and Forestry Greenhouse Gas Inventory: 1990-2018' serves to estimate U.S. GHG emissions for the agricultural sector, to quantify uncertainty in emission estimates, and to estimate the potential of agriculture to mitigate U.S. GHG emissions. This dataset contains tabulated data from the figures and tables presented in Chapter 5, Energy Use in Agriculture, of the report. Data are presented for carbon dioxide emissions from on-farm energy use. Please refer to the report for full descriptions of and notes on the data.
Data from: Chapter 4: Carbon Stocks & Stock Changes in U.S. Forests. U.S. Agriculture and Forestry Greenhouse Gas Inventory: 1990-2018
The report 'U.S. Agriculture and Forestry Greenhouse Gas Inventory: 1990-2018' serves to estimate U.S. GHG emissions for the agricultural sector, to quantify uncertainty in emission estimates, and to estimate the potential of agriculture to mitigate U.S. GHG emissions. This dataset contains tabulated data from the figures and tables presented in Chapter 4, Carbon Stocks & Stock Changes in U.S. Forests, of the report. Data are presented for above and below-ground carbon stocks and stock changes.
Data from: Chapter 3: Cropland Agriculture. U.S. Agriculture and Forestry Greenhouse Gas Inventory: 1990-2018
The primary greenhouse gas (GHG) sources for agriculture are nitrous oxide (N2O) emissions from cropped and grazed soils, methane (CH4) emissions from ruminant livestock production and rice cultivation, and CH4 and N2O emissions from managed livestock waste. This dataset contains tabulated data from the figures and tables presented in Chapter 3, Cropland Agriculture, of the report. Data are presented for Cropland Soils (N2O), Rice Cultivation + Residue Burning (CH4 + N2O), and Agricultural Soil Carbon and Amendments (CO2).
Data from: Chapter 2- Livestock and Grazed Lands Emissions. U.S. Agriculture and Forestry Greenhouse Gas Inventory: 1990-2018
The primary greenhouse gas (GHG) sources for agriculture are nitrous oxide (N2O) emissions from cropped and grazed soils, methane (CH4) emissions from ruminant livestock production and rice cultivation, and CH4 and N2O emissions from managed livestock waste. This dataset contains tabulated data from the figures and tables presented in Chapter 2, Livestock and Grazed Lands Emissions, of the report. This chapter covers carbon dioxide, methane, and nitrous oxide emissions and removals due to enteric fermentation, animal waste management, and land use for confined and grazed animals.
Data from: Chapter 1, Introduction. U.S. Agriculture and Forestry Greenhouse Gas Inventory: 1990-2018

This dataset contains tabulated data from the figures and tables presented in Chapter 1, Introduction, of the report. Data are presented for Cropland Soils (N2O), Enteric Fermentation (CH4), Managed Livestock Waste (CH4 + N2O), Grazed Lands (CH4 + N2O), Rice Cultivation + Residue Burning (CH4 + N2O), Energy Use, Forests, Harvested Wood, Urban Trees, and Agricultural Soils.
Improved Tropical Forage Fertilizer-P Calibration: In support of FRST to conduct state-level soil-fertility correlation and calibration trials for P and/or K
There is a need to validate current soil test critical levels as well as carry out calibration studies (crop response to fertilizer P at varying soil test levels). We report on a calibration experiment using an improved tropical forage, Brachiaria decumbens in a soil with soil test P in the Low category.
Legacy Phosphorus and Potassium Correlation Experiments: Qulin, Missouri
Correlation experiments for P and K were conducted from 1968-1973 at a research farm in Qulin, Missouri to better define the relationships between soil tests, crop yields, and fertilizer treatments. Three crop rotations each were conducted for P and K trials (ranges C, D, E, F, G, and H), and included corn, soybean, wheat, cotton, and sorghum.
