Quantifying in situ solute transport through soils and the landscape has been widely acknowledged as important and yet challenging. The objective of this study was to evaluate water and bromide movement in no-tilled (NT) and conventionally tilled (CT) corn using two different types of in situ lysimeters—pan and capillary wick— for single rainfall events. Four zero-tension pan and four capillary-wick lysimeters were installed 1.2 m deep on opposite sides of four soil pits. Two were under NT corn, and two were under CT corn. Bromide (Br) was either surface applied or applied with an initial 25 to 27 mm of …
Tillage Effects On Soil Quality Indicators And Nematode Abundance In Loessial Soil Under Long- Term No-Till Production, R. B. Mendoza, T. G. Franti, John W. Doran, Thomas O. Powers, C. W. Zanner
Tillage Effects On Soil Quality Indicators And Nematode Abundance In Loessial Soil Under Long- Term No-Till Production, R. B. Mendoza, T. G. Franti, John W. Doran, Thomas O. Powers, C. W. Zanner

Soil quality indicators and nematode abundance were characterized in a loessial soil under long-term conservation tillage to evaluate the effects of no-till, double-disk, chisel, and moldboard plow treatments. Indicators included soil electrical conductivity (EC), soil texture, soil organic matter (SOM), and total particulate organic matter (tPOM). Nematode abundance was positively correlated with EC, silt content, and total POM and negatively correlated with clay content. Clay content was the main source of variation among soil quality indicators and was negatively correlated with nematode abundance and most indicators. The gain in SOM in the no-till system amounted to 10887 kg over the …
