“…Filter candles and plates (ROBU® Glasfilter‐Geräte GmbH) consisted of borosilicate glass 3.3. Borosilicate was chosen for its property of neither adsorbing significant amounts of PO $ _4^{3 - } $ ( Bottcher et al, 1984) nor DOC ( Wessel‐Bothe et al, 2000). The filters had a pore size of 10–16 µm to allow the passage of colloids.…”

Phosphorus (P) is essential for sustainable forest growth, yet the impact of anthropogenic impacts on P leaching losses from forest soils is hardly known. We conducted an irrigation experiment with 128 mesocosms from three forest sites representing a gradient of resin extractable P of the A‐horizon. On each site we selected a Fagus sylvatica and a Picea abies managed subsite. We simulated ambient rain (AR), anthropogenic nitrogen input (NI) of 100 kg (ha · a)−1 and forest liming (FL) with a dolomite input of 0.3 Mg (ha · a)−1. Soil solution was extracted from the organic layer, 10 cm depth and 20 cm depth of the mesocosms, and analyzed for molybdate reactive phosphorus (MRP) and molybdate unreactive phosphorus (MUP). Additionally, we separated colloids from the soil solution using Asymmetric Field Flow Fractionation for assessing the colloidal fraction of total element concentrations. NI increased MRP and MUP concentrations for all plots with one exception, while FL decreased MRP and MUP with the exception of another plot. While the irrigation treatments had little impact on the P‐richest site, MRP and MUP concentrations changed strongly at the poorer sites. The colloidal fraction of P in the soil solution equaled 38–47% of the total P load. Nitrogen input and liming also affected the Fe, Al, Ca, and Corg contents of the colloidal fraction.

“…The phosphate ion has a strong affinity to metal hydroxides to which it is specifically bound by ligand exchange. Ceramic materials that contain aluminium (hydr)oxide therefore sorb and desorb considerable quantities of PO 4 3− (Bottcher et al, 1984). The sorption and desorption of PO 4 3− in suction cups and plates can be prevented by using porous PTFE (polytetrafluoroethylene, eg., Teflon) or glass, whereby porous PTFE exhibit low air entrance values due to its hydrophobic surface (Bottcher et al, 1984).…”

In Situ Soil Water Extraction: A Review

The knowledge of the composition and fluxes of vadose zone water is essential for a wide range of scientific and practical fields, including water-use management, pesticide registration, fate of xenobiotics, monitoring of disposal from mining and industries, nutrient management of agricultural and forest ecosystems, ecology, and environmental protection. Nowadays, water and solute flow can be monitored using either in situ methods or minimally invasive geophysical measurements. In situ information, however, is necessary to interpret most geophysical data sets and to determine the chemical composition of seepage water. Therefore, we present a comprehensive review of in situ soil water extraction methods to monitor solute concentration, solute transport, and to calculate mass balances in natural soils. We distinguished six different sampling devices: porous cups, porous plates, capillary wicks, pan lysimeters, resin boxes, and lysimeters. For each of the six sampling devices we discuss the basic principles, the advantages and disadvantages, and limits of data acquisition. We also give decision guidance for the selection of the appropriate sampling system. The choice of material is addressed in terms of potential contamination, filtering, and sorption of the target substances. The information provided in this review will support scientists and professionals in optimizing their experimental set-up for meeting their specific goals.

“…Several methods exist to sample the soil solution, each with its own limitations, advantages, and disadvantages (Litaor 1988), but lysimetry is currently the most common way to obtain soil solution samples . Repeated sampling with time on the same location is by far the major advantage of this method (Bottcher, Miller, and Campbell 1984).…”

Because the widely used ceramic cups are reported to release, adsorb, and filter dissolved nutrients from soil solution samples, inert cups made of poly(tetrafluoroethene) (PTFE) are frequently proposed as a more reliable alternative. A ceramic and a PTFE/quartz cup were compared with each other in this laboratory study. The PTFE/ quartz cup was the most suited for pH measurements. Because only the ceramic cup samples both ammonium and nitrate in a satisfactory way, this cup type is recommended for nitrogen (N) balance studies. In most cases, the ceramic cup also performed better in sampling cations [sodium (Na þ ), potassium (K þ ), calcium (Ca 2þ ), magnesium (Mg 2þ )] than the PTFE/quartz cup. Both cup types seemed inadequate to sample soil solution for aluminum (Al 3þ ) determinations. The ceramic cups released chloride (Cl 2 ) at low ion concentrations, but sulfate (SO 4 22 ) concentrations remained almost unaltered in the sample as compared to the solution outside the cup. In contrast, Cl 2 and SO 4 22 were retained by the PTFE/quartz cups. The overall conclusion of this study is that PTFE/quartz cups have no clear advantages over the more widely used ceramic
