Impacts of soil management practices on soil fertility in potato-based cropping systems in the Bolivian Andean highlands
(University of Missouri--Columbia, 2010)
(LC) and fallow (LF) showed that LC decreased and LF increased total (TOC) and active soil organic C (AOC), and total (TN), inorganic (TIN) and active soil N (AIN). Field trials established with combinations of soil inorganic fertilizers (SIF...
Soil surface-seal measurement using high-resolution x-ray computed tomography (HRCT)
(University of Missouri--Columbia, 2006)
Rainfall on bare soil breaks soil aggregates, detaching particles, plugging pores and decreasing porosity in the top few mm of soil. This reduces hydraulic conductivity and increases runoff through a process known as surface ...
Greenhouse gas emissions and soil microbial activity for selected land use systems in floodplains
(University of Missouri--Columbia, 2022)
.]/soybean [Glycine max (L.) Merr.]} rotation (AG), in the Missouri River floodplains (MRF); 2) to assess the influence of AF, RF, and AG land management systems located in MRF on the emission of soil GHG; and 3) to evaluate the effects of various soil moisture...
Anthropogenic effects on soil physical, chemical, and biological properties in the Missouri Ozarks
(University of Missouri--Columbia, 2018)
in the Missouri Ozarks: BS; CF%; exchangeable Ca2+ and K+; C:N; ECEC; pH; TN; TOC:AC; T; and Bray-1 P. Although fine fraction bulk density was not found to be sensitive to harvest in this study, we would recommend it be retained as part of a soil health assessment...
Effects of a consortia probiotic inoculant on soil microorganisms and impacts on autoinducers employed in quorum sensing
(University of Missouri--Columbia, 2013)
to degrade autoinducers involved in QS in soil-borne pathogens. The first efficacy was assayed in Central Missouri during growing season of 2012. Soils under two management situations were studied: cultivated soil and restored grassland. Samples from...
Utilization and limitations of soil health metrics in Missouri corn production decisions
(University of Missouri--Columbia, 2022)
derive from a dataset collected over three seasons (2018-2020) including 446 sample locations collected from 101 Mid-Missouri commercial row crop systems. Current P and K fertilizer recommendations accurately identified where fertilizer improved yield...
