“…The low aggregate stability and the high structure vulnerability were reflected also due to the high contents of WSA mi (Figure 2) in haplic Chernozems. Intensive tillage disrupts soil aggregates (Balashov et al, 2010;Plante and McGill, 2002;Six et al 2000;Slowinska-Jurkiewicz et al, 2013). Opposite situation was observed in mollic Fluvisols.…”

This study was performed to evaluate effects of minimum (MT) and conventional tillage (CT) on soil organic matter and soil structure in haplic Chernozems and mollic Fluvisols. The content of soil organic carbon (C org ) as well as parameters of stability and vulnerability of soil structure were quantified. The results showed that soil type had statistically significant influence on C org . In haplic Chernozems the C org content near the surface (0-0.1 m) was significantly higher under MT (by 6%) compared to CT, however, in layer 0-0.3 m under CT the average C org content was by 16% higher than under MT. In mollic Fulvisols under MT, the average C org content (17.5 ± 5.4 g*kg -1 ) was significantly less for the 0-0.3 m layer than the CT (22.7 ± 0.4 g*kg -1). In Chernozems, total content of water-stable micro-aggregates (WSA mi ) was higher in MT (90.8%) than in CT (69.5%). In mollic Fluvisols, the average content of WSA mi was higher in CT (62.5%) than in MT (53.2%). The low aggregate stability and the high structure vulnerability were reflected also due to the high contents of WSA mi in both soils. The stability of aggregates was a higher in mollic Fluvisols than in haplic Chernozems. In haplic Chernozems, better soil structure stability was under CT than MT, on the other hand, in mollic Fluvisols, the average value of coefficient of aggregate stability was lower by 32% in CT than MT.

“…Long-term agricultural use of soils without proper crop rotation and mineral nitrogen and organic fertilization may lead to a decrease in the soil organic matter content due to the predominance of mineralization processes (S³owiñska-Jurkiewicz et al, 2013). The soil TN content in the soil ranged from 0.84 to 1.02 g N kg -1 (Table 1).…”

“…Providing soil with organic fertilizers affects its physical and chemical properties more than that with nitrogen ones. Farmyard manure (FYM) is the most popular natural fertilizer and is considered as one of the most effective fertilizers in the soil environment (S³owiñska-Jurkiewicz et al, 2013). Mineral, organic, and natural fertilization also stimulates the development of microorganisms being a main source of enzymes responsible for nutrients transformations in soils (Bieliñska and Mocek-P³óciniak, 2012;George et al, 2002;Krämer and Green, 2000).…”

A b s t r a c t. The paper demonstrates the results of research on the mobility of phosphorus and sulphur in winter wheat fertilized with several rates (0, 20, 40, 60, 80 t ha -1 ) of farmyard manure and nitrogen (0, 40, 80, 120 kg N ha -1 ). The content of these nutrients was related to the activity of acid phosphatase and arylsulphatase in a Haplic Luvisol. The highest content of available phosphorus (91.58 mg P kg -1 ) was reported in the soil amended with farmyard manure at the rate of 60 t ha -1 . The content of sulphates (VI) in the Haplic Luvisol was high and, on average, equal to 25.22 mg kg -1 . The activity of acid phosphatase in the soil increased with increasing mineral nitrogen rates. The highest content of sulphates (VI) and the lowest activity of arylsulphatase were identified at the nitrogen rate of 40 kg N ha -1 . The mobility of phosphorus in winter wheat was the highest when farmyard manure at the rate of 60 t ha -1 and mineral nitrogen at the rate of 120 kg N ha -1 were incorporated into the soil. The greatest translocation of sulphur was reported at the high farmyard manure rates (40, 60 and 80 t ha -1 ) and the nitrogen rate of 80 kg N ha -1 .

Crop Area Mapping Using 100-m Proba-V Time Series

et al. 2016

A method was developed for crop area mapping inspired by spectral matching techniques (SMTs) and based on phenological characteristics of different crop types applied using 100-m Proba-V NDVI data for the season 2014-2015. Ten-daily maximum value NDVI composites were created and smoothed in SPIRITS (spirits.jrc.ec.europa.eu). The study sites were globally spread agricultural areas located in Flanders (Belgium), Sria (Russia), Kyiv (Ukraine) and Sao Paulo (Brazil). For each pure pixel within the field, the NDVI profile of the crop type for its growing season was matched with the reference NDVI profile based on the training set extracted from the study site where the crop type originated. Three temporal windows were tested within the growing season: green-up to senescence, green-up to dormancy and minimum NDVI at the beginning of the growing season to minimum NDVI at the end of the growing season. Post classification rules were applied to the results to aggregate the crop type at the plot level. The overall accuracy (%) ranged between 65 and 86, and the kappa coefficient changed from 0.43-0.84 according to the site and the temporal window. In order of importance, the crop phenological development period, parcel size, shorter time window, number of ground-truth parcels and crop calendar similarity were the main reasons behind the differences between the results. The methodology described in this study demonstrated that 100-m Proba-V has the potential to be used in crop area mapping across different regions in the world.
