Leaching Losses, Runoff, and Percolate From Eight Illinois Soils¹

Abstract

HIS is the third in a series of reports on leaching losses, T r u n o f f , and percolate produced by natural precipitation on eight Illinois soils. Measurements were made on triplicate profiles of each of the eight soils in erosion-type lysim

A Study of Forest Soils and Leachates on Sloping Topography Using a Tension Lysimeter

“…The concentration of ions in water passing through the soil is an approximate measure of translocation and possible loss of nutrients frorn the soil. The nutrient content of leachates has been studied by a number of investigators with particular reference to amount of percolate (Dreibelbis and McGuinness 1957;Stauffer and Rust 1954), season of the year (Cole et al 1961;Lunt 1942;Shilova and Korovkina 7961), soil type (Cole et al 196l;Dreibelbis 1954) and soil genesis (Joffe 1933;Kohnke et al l94O;Shilova and Korovkina 1961;Smirnova and Glebova 1958). Although the data should not be taken as absolute values, generalizations can be used for interpretations of nutrient loss and ion movement.…”

Plant‐Nutrient Losses in Lysimeter Percolates1

“…One of the most recent investigations of this nature 1s. that of Stauffe~ and Rust ( 6). In their study which included e1ght different sod types in Illinois, leaching losses generally were found to correlate with amount of j:lercolate but this was not al;vays the case.…”

Comparison of Rooting in Soil Parent Materials Using Undisturbed Soil Cores1

“…The literature has only a few references to the use of undisturbed cores in agronomic research. The chief uses appear to have been for estimation of hydraulic factors in lysimeter work (6,7) and for assessing the effects on roots of compacted layers in soils (4)-Undoubtedly this is partly due to the difficulty c•f obtaining undisturbed cores. However, with the use of hydraulically operated coring machines, this task is now comparatively simple, and the use of such cores in agronomic research should be evaluated.…”
