Observations were collected from CaNPK and Ca fertilization systems (further referred to as NIL due to the absence of nitrogen (N) fertilizers) in two consecutive years (2012 and 2013) on a long-term (since 1923) field experiment in Skierniewice in Central Poland. N2O emissions from the soil were measured in situ by the means of infrared spectroscopy using a portable FTIR spectrometer Alpha (Bruker). N2O fluxes from soils treated under CaNPK and NIL treatments were similar. No significant influence of the current treatment or cropping on the N2O emissions was noted in the CaNPK treated soil. N2O emissions in 2012 (barley, ammonium nitrate application) and 2013 (lupine, no mineral nitrogen application) were similar (0.17-23.04 g N2O-N/ha/day, median 4.29 and 0.09-19.46 g N2O-N/ha/day, median 4.45, respectively). During the growing period of 2012 (barley, ammonium nitrate application), the N2O-N emissions from the CaNPK treated soil (uncorrected for NIL) represented 1.02% of the applied N dose. In the growing period of 2013 (lupine, no mineral nitrogen application), the yield-scaled N2O-N emissions from CaNPK and NIL treatments equaled respectively to 4.4 g and 5.4 g N2O-N per 1 kg of nitrogen accumulated by lupine.

The experiment was located at the Research Station of the UTP University of Science and Technology in Bydgoszcz (Poland). The long-term application of nitrogen and potassium fertilizers leads to changes in the concentration of mercury, soil acidification, reduction in total organic carbon, total nitrogen as well as affluence of available nutrients (P, K, Mg) and increased mobility of copper and zinc. The significant positive correlation between total mercury content in the soil and the content of N-NO3, Zn, N-NH4 and the hydrolytic acidity value were stated.

In this context, the objective of this study was to analyse the carbon balance in systems of coffee production, which can contribute to information to mitigate climate change, by addressing the cultivation and production of Coffea spp. in the tropical regions, such as the Espírito Santo state of the case study (between the meridians 39°38' and 41°50' of western longitude and the parallels 17°52' and 21°19' of southern latitude). For this purpose, data of coffee plantations area (ha), carbon storage, carbon footprint and carbon balance (all in t CO2-equivalent) were recorded for different tropical regions, from 2001-2012. The estimated parameters indicate that 2 239 476 t CO2-eq were sequestrated (positive balance) and 10 320 223 t CO2-eq (negative balance) were emitted. The spatialisation allows estimating that the footprint is reduced in 92% after quantifying the carbon stock in coffee plantations. The carbon balance was negative, with magnitude of 4 815 820 t CO2-eq, which indicates that the carbon balance in coffee plantations in tropical regions is not enough to compensate the carbon footprint.

The aim of the study was to evaluate different requirements of the selected cultivars in regard to the ridge and tuber cluster. The following parameters were defined and monitored: area of the form surrounding the tubers (ellipse), cross-sectional area of the ridge, vertical and horizontal tuber span in the ridge, the length of semi-axes (a) and (b) of the ellipse, minimum distance of tubers and ellipse from the outer ridge side. The results of 2012 trial indicated that the minimal ellipse method defining the ellipse was not satisfactory as statistical significance was limited due to a large volume of vacant space in the ridge not occupied by potato tubers. Therefore, the mathematical model was upgraded in 2013 and a physical parameter (tuber mass) was incorporated in the equation to better depict the tuber cluster. The trials were designed as a randomized block with five repetitions. The largest ellipse, horizontal tuber span in the ridge and the longest semi-axis (a) were recorded for the cv. Manitou resulting in the highest yield. However, no statistical differences were recorded in the horizontal tuber span, the length of the semi-axis (a) or cross-sectional area of the ridge among cultivars analysed. It was determined that different cultivars require specific growth space in the potato ridge. Moreover, the newly developed method proved efficient for determining growth requirements of potato tubers in the ridge.

The study involved 9 hybrids with different parameters that were grown during a period of three subsequent years in two locations with different level of precipitation. Differences in terms of the content of dry matter between the hybrids at different timing of harvests were small (323 ± 22 g/kg), showing no statistical significance (P = 0.34). Comparing the early maturity hybrids with the medium early hybrids (P < 0.05), the former showed a lower content of starch (299 g/kg dry matter (DM)), and the latter showed a slightly higher value (312 g/kg DM) - while the measured proportion of neutral detergent fibre (NDF) among these two hybrids was 453 vs. 428 g/kg DM. Comparing the measured value of the normally ripening hybrids against the stay-green hybrids, the starch was 314 vs. 294 g/kg DM, and NDF was 434 vs. 451 g/kg DM, respectively. As for the comparison between the flint (vitreous) type of grain endosperm vs. dent (floury), measured value of the starch was 298 vs. 323 g/kg DM, and NDF was 451 vs. 427 g/kg DM, respectively.

Data of two growing cycles in the years 2007-2010 and 2011-2014 were evaluated. Tillage technique was decisive for changes in soil characteristics and crop yields. Bulk density, organic carbon (Corg) and microbial biomass C (Cmic) were more equilibrated throughout all tested soil layers (0-0.1; 0.1-0.2 and 0.2-0.3 m) in conventional tillage (CT). In reduced tillage (RT) and no-tillage (NT) treatments significant accumulation of Corg and increase of Cmic in the surface layer were found, compared to CT. No significant differences in Corg and Cmic between two growing cycles were determined; however, mostly higher values were obtained in the top layer of NT during the second growing period. Higher bulk density under conservation tillage techniques did not negatively affect soil characteristics and should be taken in consideration for data evaluation as it can alter interpretation of their changes in the soil profile. Crop yields were comparable in CT and RT. Yield decrease in NT was mostly observed for winter wheat and pea. Beneficial effects of RT and NT conserving soil moisture on crop yield were not observed in dry years.

This experiment was conducted in Delicias, Chihuahua, Mexico. The results indicate that the accumulation of Fe in bean seeds enhanced with the application of Fe-EDDHA, at the dose of 25 µmol. This demonstrated that low Fe application dose was enough to increase Fe levels in seeds of common bean. In addition, Fe-EDDHA application form at 50 µmol was the best treatment to improve crop yield. With respect to antioxidant system, chelated form of Fe (Fe-EDDHA) was more effective in the activation of antioxidant enzymes (catalase, superoxide dismutase and glutathione peroxidase), and a lower content of H2O2 in green bean seeds.
