	abstract = {The paper presents the investigation of ASAR images usefulness to control arable land over winter. In order to account for environmental concerns related to agricultural activities, farmers have to respect the Good Agricultural and Environmental Conditions (GAEC) to get their subsidies. The GAEC must be defined by each country of Member States. One of the GAECs is the prohibition of ploughing parcels above a give slope over the winter period. A cost effective strategy for identifying farms not respecting this GAEC is remote sensing. Due to weather conditions in winter over Europe, there is a high risk of not acquiring a suitable optical image. Therefore it is worth assessing whether radar images can be valuable alternative to optical data for detecting ploughed parcels independently from weather conditions.
		
		To evaluate the degree of radar data usefulness an experiment for Belgian test sites was initiated. Over Wallonia, there were available: the radar and optical images, the vector parcels from LPIS and other auxiliary data (DEM, orthophotomap, meteorological conditions). The study was divided into two separate parts which together constitute complete experiment. The first part was focused on the ploughing detection, while the second part was dedicated to bare soil recognition. Detection of ploughing on the radar images had been examined using the supervised classification methodology based on the time-series compositions. The unsupervised classification of radar images towards to distinguish bare soil and vegetation was tested. 
		
		The paper presents also the assessment of the results displayed in the analysis section. Although the confusion between ploughed and sown parcels occurred, the identification of ploughing based on ASAR images analysis is possible with high probability. The detection of bare soil as risky area is feasible on radar data with quite high accuracy as well.
