dcterms:description
The aim of this paper was to compare the rate of infiltration and cumulative infiltration in permanent grassland (PG) and in arable land over the course of the 2011 growing season. The measurement of water infiltration into soil was conducted via ponded infiltration method based on the use of two concentric cylinders in field conditions. Kostiakov equations were applied to evaluate the ponded infiltration. Based on field measurements, the dependence of infiltration rate (v) on time (t) was determined and also the dependence of cumulative infiltration (i) on time (t). In order to determine physical properties of soil and carry out a grain size analysis, intact soil samples of plough layer from the depths of 10, 20 and 30 cm were collected using Kopecký cylinders along with individual infiltration attempt in each measurement carried out on experimental plots. In order to assess the infiltration capacity of soil on experimental plots, four measurements were conducted, each with three repetitions. Infiltration attempts were held on May 12, June 28, August 24 and October 6, 2011. On average, a faster water infiltration into soil and a higher cumulative infiltration during the 2011 growing period were detected in arable land. The soil's initial water content has proven to be the crucial factor affecting the rate of water infiltration into soil in case of PG; in case of arable land, it was bulk density indicating the soil's compaction. The PG showed a more balanced course of infiltration rate and cumulative infiltration values during the growing season. Arable land is characterized by a greater dispersion of measured values between individual measurement dates.
