This paper brings the comparison of characteristic changes of cropland and of land that has been left fallow for ten years. The disruption of soil structure (MWD) was tested and correlated with basic soil parameters (soil texture, soil hydraulic properties (Ksat), soil organic matter content (Cox), gentle acidification (pHKCl)). Sub-wetting processes of MWDs for three soil types (Chernozems, Cambisols, Luvisols) were tested and confronted with the results of a small-rainfall simulator in laboratory conditions. Statistically provable changes occurred on the plots of fallow land, i.e.: (i) decreased risk of water erosion...

The purpose of this research has been to identify relationships between soil moisture and the growth and development of microorganisms, their diversity and the activity of soil enzymes. Four soils with different texture were analysed. Air-dry soils were watered up to the moisture content corresponding to 20, 40 and 60% of the maximum water capacity (MWC) and subsequently were submitted to determinations of the counts of soil microorganisms, colony development index and ecophysiological diversity index for bacteria, actinomycetes and fungi. In addition, the response of seven soil enzymes to soil humidity was examined. It was found that the most optimum...

The objective of the study was to determine the effect of biostimulants and herbicides on the level of glycoalkaloids in leaves and tubers of three table potato cultivars. The following factors were examined: I - potato cultivars: Bartek, Gawin, Honorata; II - five weed control methods (application of biostimulants and herbicides: 1. mechanical weed control - control treatment and four herbicide or herbicide + biostimulant treatments (Harrier 295 ZC, Harrier 295 ZC + Kelpak SL, Sencor 70 WG, Sencor 70 WG + Asahi SL). The potato tuber content of glycoalkaloids was significantly affected by genotype. The highest total glycoalkaloid (TGA) content was...

The experiments were conducted in four locations in Serbia: Valjevo, Kucevo, Nova Pazova and Surduk in 2012 and 2013. A working hypothesis that growing conditions would not affect the rutin content in buckwheat leaves was set up. The content of rutin in leaves of buckwheat was determined by the HPLC/DAD technique, using the external standard calibration method. Out of the basic biometric parameters, average value, variance, and the variation coefficient were estimated. Results were processed by the analysis of variance for the factorial experiment. The analysis of variance showed existence of significant differences in the rutin content, over locations,...

Plant Soil Environ., 2016, 62(6):266-273 | DOI: 10.17221/363/2015-PSE  

The present study was set up to investigate the effect of irrigation with naturally arsenic (As)-contaminated water and addition of organic amendments on the As accumulation in frequently consumed vegetables in India (pumpkin, radish and cabbage). An arsenic-stricken village (Ghentugachi, Chakdah Block, Nadia, West Bengal, India; 23°02'N, 88°34'E, 9.75 m a.s.l.) was selected. Pot studies were conducted with the selected vegetables in contaminated soils collected from the selected village. Arsenic-contaminated water (spiked with varying concentrations of AsIII and AsV) was used to irrigate the pots. Use of irrigation water contaminated...

Plant Soil Environ., 2016, 62(6):274-278 | DOI: 10.17221/16/2016-PSE  

Three treatments were used in a two-year (2014-2015) vegetation pot experiment with kohlrabi of the cv. Moravia: (1) untreated control; (2) digestate; (3) digestate + phosphorus (P). The nitrogen (N) rate was the same in treatments 2-3. There were significant differences between years in all parameters. The weight of single kohlrabi bulbs in the unfertilised control was significantly lower in both years (33.1-46.9%) than in the digestate treatment (100%). Digestate supplemented with P (treatment 3) increased the bulb yield significantly by 11.0-14.3% compared with pure digestate (treatment 2). In both years the content of bulb nitrates (mg NO3-/kg...

This research was conducted to assess the influence of long-term tillage system on soil organic carbon, microbial biomass carbon, root biomass and crop yield in spring wheat-field pea rotation fields in a rainfed semi-arid environment from 2013 through 2015. The treatments were; conventional tillage with stubble removed (T); no-till with stubble removed (NT); no-till with stubble retained (NTS) and conventional tillage with stubble incorporated (TS) arranged in a randomised complete block design with three replicates. The soil organic carbon in NTS increased by 16% and 14% over T and NT. Compared with the T and NT, NTS increased soil microbial biomass...

M. Płatkowski, A. Telesiński

Plant Soil Environ., 2016, 62(6):286-292 | DOI: 10.17221/673/2015-PSE  

This paper assesses the impact on certain phosphatase activities in soil of glyphosate and its formulations, i.e.: Roundup 360 SL and Roundup TransEnergy 450 SL, which contain various glyphosate salts (isopropylamine and potassium) and various surfactants (polyethoxylated tallow amine and polyethoxylated ether amine). The experiment was carried out on sandy loam samples with organic carbon content of 10.9 g/kg. Aqueous solutions of pure glyphosate and its formulations were added to the soil. The amounts of applied glyphosate and its salts were: 1, 10 and 100 mg/kg. On days 1, 7, 14, 28 and 56 the activity of alkaline phosphomonoesterase (ALP); acid...
