Sample processing impacts on single wet sieve aggregate stability analysis

Autor: Glenn Arthur Garcia, Jason G. Warren, Sergio Abit, Chime Garcia, Grace Flusche Ogden

Publikováno v: Agricultural & Environmental Letters, Vol 7, Iss 2, Pp n/a-n/a (2022)

Abstract Soil aggregate stability is widely considered an indicator of soil health. However, there is a lack of test procedure standardization for this soil property. Presently, air‐drying and manual grinding are commonly used in preparing samples

Sampling probes affect bulk density and soil organic carbon measurements

Autor: Sumit Sharma, Tracy Wilson, Tyson Ochsner, Jason G. Warren

Publikováno v: Agricultural & Environmental Letters, Vol 5, Iss 1, Pp n/a-n/a (2020)

Abstract Soil sampling equipment can be a major source of bias in soil organic carbon (SOC) stock estimations. The objective of this study was to evaluate the impact of sampling probes on soil bulk density (BD) and SOC stocks calculated using fixed d

An Automated Laboratory Method for Measuring CO2 Emissions from Soils

Autor: Eric B. McGowen, Sumit Sharma, Shiping Deng, Hailin Zhang, Jason G. Warren

Publikováno v: Agricultural & Environmental Letters, Vol 3, Iss 1 (2018)

A gas chromatography (GC) headspace method was developed for soil microbial respiration (CO emission) analysis after a 24-h incubation of a rewetted soil. The GC method was compared with the Solvita CO burst method by analyzing 18 different soils tha

Soil Salinity Variations in an Irrigation Scheme during a Period of Extreme Dry and Wet Cycles

Autor: Sheyda Chamaki, Saleh Taghvaeian, Hailin Zhang, Jason G. Warren

Publikováno v: Soil Systems, Vol 3, Iss 2, p 35 (2019)

Salinization of irrigated lands is a major challenge towards supplying required food and feed to meet the needs of an increasing global population. In this study, the changes in soil salinity and several other chemical properties were investigated in

The Efficiencies, Environmental Impacts and Economics of Energy Consumption for Groundwater-Based Irrigation in Oklahoma

Autor: Divya Handa, Robert S. Frazier, Saleh Taghvaeian, Jason G. Warren

Publikováno v: Agriculture, Vol 9, Iss 2, p 27 (2019)

Irrigation pumping is a major expense of agricultural operations, especially in arid/semi-arid areas that extract large amounts of water from deep groundwater resources. Studying and improving pumping efficiencies can have direct impacts on farm net
