“…However, the initial ST of a plough layer may be modified by transport processes related to tillage, harvests of root or tuber crops and erosion. Thus, the texture also depends on the topography of the field and management practices ( Koćmit and Podlasiński , 2002; Brevik et al, 2003; Paluszek , 2010; Urricariet et al, 2011; Pontes de Oliveira et al, 2013; Rejman et al, 2014). The soil texture of both the plough layer and subsoil is modified very slowly by the eluviation of clay to the deeper layers, which occurs in many landscapes ( Bockheim and Hartemink , 2013).…”

Soil texture (ST) is relatively stable over time, although it may change due to erosion, clay eluviation, and other processes. Soil texture affects soil quality, productivity and management. Therefore, indirect, accurate methods for assessing of soil texture classes (STCs) are needed in agricultural practice. A study was performed on four production fields in northern and central Poland to compare the fitting performance of STC models based on apparent electrical conductivity (ECa), topographic properties (elevation, slope gradient and wetness index) and Amber NDVI measurements. One common and accurate indicator of STCs was not found for all study fields. On average, ECa was most accurate in indicating areas of different STCs within the fields, but it tended to overestimate the size of sandy areas on loamy fields and vice versa. The accuracy of STC assessment using ECa measurements may be biased due to imperfect soil drainage, high elevations, which increase evaporation and STC variation with depth. STC assessment using Amber NDVI measurements may be useful, particularly on flat and sandy fields, but the results are affected by the same factors as ECa, and additionally by crop growth stages and by the weather conditions in the period preceding the measurements. Despite the good quantitative results of the STC assessment by elevation (one field) and by the topographic wetness index (another field), both terrain attributes failed to accurately indicate the distribution of some STC areas within each field. Therefore, in landscapes developed from deposits of the last glaciation relevant ST differences might not sufficiently be detected by the analysis of terrain attributes alone. The selection of STC predictors and evaluation of the assessment quality must consider both the quantitative indicators such as correlation and determination coefficients describing relationships between ST and ECa, NDVI and topography and percentage of a field area with accurately indicated STC and the distribution of areas with different STCs within a field. The use of ECa, NDVI values, and topographic properties for STC assessment may be useful in reducing costs of soil sampling and analysis, but cannot replace it.

“…Sum of accumulated and eroded soil material for all studied profiles was 29.52 and 32.59 m, respectively. The amounts divided by total number of profiles showed that the average profile was overbuilt by 0.23 m and eroded by 0.26 m. Assuming that soil density is 1.3 Mg m −3 [ 13 ] total erosion was 4394 Mg. From that amount, 88% was deposited within the study area, and 12% removed outside. Taking into account the period of arable land use of the area (185 years), total soil erosion was 23.8 Mg ha −1 year −1 in the studied area, that is, 1.41 mm year −1 .…”

The change of primary forest areas into arable land involves the transformation of relief and modification of soils. In this study, we hypothesized that relatively flat loess area was largely transformed after the change of land use due to erosion. The modifications in soil pedons and distribution of soil properties were studied after 185 years of arable land use. Structure of pedons and solum depth were measured in 128 and soil texture and soil organic carbon in 39 points. Results showed that soils of noneroded and eroded profiles occupied 14 and 50%, respectively, and depositional soils 36% of the area. As a consequence, the clay, silt, and SOC concentration varied greatly in the plowed layer and subsoil. The reconstructed profiles of eroded soils and depositional soils without the accumulation were used to develop the map of past relief. The average inclination of slopes decreased from 4.3 to 2.2°, and slopes >5° vanished in the present topography. Total erosion was 23.8 Mg ha−1 year−1. From that amount, 88% was deposited within the study area, and 12% was removed outside. The study confirmed the hypothesis of the significant effect of the land use change on relief and soils in loess areas.

“…Wraz ze spadkiem nachylenia oraz wzrostem długości stoku udział erozji uprawowej maleje na rzecz erozji wodnej. Wpływ erozji agrotechnicznej na kształtowanie rzeźby jest zatem szczególnie duży na lessowych obszarach rolniczych, charakteryzujących się drobnopromienną rzeźbą o krótkich i stromych, zwykle wypukło-wklęsłych, rozczłonkowanych stokach (Rodzik 2001, Rejman i in. 2014.…”
