Eighteen cultivars of blue lupine seeds were examined to indicate the one most favourable in protein content and quality. Two parameters were studied, i.e. total protein content (with the Kjeldahl method) and amino acids composition (with the ultra performance liquid chromatography technique). Both parameters studied were variable and depended both on the cultivar and on the place of cultivation. Protein content was in the range of 28-41% and the worst cultivar, regardless of cultivation place, was cv. Kalif (average total protein content 29.37 ± 1.14%), while the best cultivar was Boruta (average total protein content 37.43 ± 0.98%). The blue lupine seeds were rich especially in leucine (5.3 ± 0.5-9.7 ± 0.5 g/16 g N), threonine (2.4 ± 0.7-4.9 ± 0.1 g/16 g N) and lysine (2.7 ± 0.4-5.6 ± 0.1 g/16 g N). The richest among all amino acids studied were the cv. Bojar seeds from Wiatrowo and cv. Oskar from Przebędowo. It was not possible to choose one cultivar preferable from the nutritional point of view, because a strong influence of cultivation place on protein content and quality was observed, especially as to the precipitation sum.

China Title: Soil nitrate accumulation and leaching in conventional, optimized and organic cropping systems Abstract: Excessive nitrogen (N) and water input, which are threatening the sustainability of conventional agriculture in the North China Plain (NCP), can lead to serious leaching of nitrate-N (NO3--N). This study evaluates grain yield, N and water consumption, NO3--N accumulation and leaching in conventional and two optimized winter wheat-summer maize double-cropping systems and an organic alfalfa-winter wheat cropping system. The results showed that compared to the conventional cropping system, the optimized systems could reduce N, water consumption and NO3--N leaching by 33, 35 and 67-74%, respectively, while producing nearly identical grain yields. In optimized systems, soil NO3--N accumulation within the root zone was about 80 kg N/ha most of the time. In the organic system, N input, water consumption and NO3--N leaching was reduced even more (by 71, 43 and 92%, respectively, compared to the conventional system). However, grain yield also declined by 46%. In the organic system, NO3--N accumulation within the root zone was generally less than 30 kg N/ha. The optimized systems showed a considerable potential to reduce N and water consumption and NO3--N leaching while maintaining high grain yields, and thus should be considered for sustainable agricultural development in the NCP.

Four treatments including control (no N), N-220 kg/ha, N-220 + NBPT and N-220 + NBPT + DCD were applied in two splits through the band placement method. Total NH3-N loss observed were 65.8, 40.5 and 20.1 NH3-N kg/ha (accounting for 29.9, 18.4 and 9.2% of N applied) from urea for YL, ZH-1 and ZH-2, respectively. The application of NBPT and NBPT + DCD significantly reduced NH3 volatilization by 80-93% and 75-90%, respectively. The meteorologic factors such as precipitation, air temperature and wind speed significantly affected NH3 volatilization. These results suggested that the amendment of urea with NBPT and NBPT + DCD have potential to mitigate NH3-N losses from alkaline soils in the Loess Plateau.

This hypothesis was verified based on 12 field experiments conducted on four farms in Poland during the seasons 2010-2012. The effect of different K, Na and Mg ratios in fertilizers applied in the total rate of 3205 mol/ha on beet yield (BY), storage root quality and white sugar yield (WSY) was determined. The tested K:Mg:Na cation ratios were as follows: 1:0:0; 1:0.11:0.09; 1:0.16:0.54 and 1:0.33:2.19. BY and WSY were affected by the total rate of the applied cations. The optimum ratio of K:Mg:Na was different with respect to the site and the growing season. The K rate reduction from 125 to 24 kg/ha combined with the simultaneous increase in the rate of Mg and Na did not result in lower BY. However, a too narrow K:Na ratio in applied fertilizers resulted in a decrease of sucrose content in storage roots. The fertilization cost for sugar beet production could be reduced through the application of fertilizers that contain fixed amounts of Na on soils rich in available K.

Maxime as well as on their uptake of the nutrients and heavy metals were studied. The media were prepared from four composts (made from: sewage sludge 70% or 35%, potato pulp 35%, straw 30% or sawdust 30%) and peat in 1:1, V:V ratio. In the 1st year of research 7-month-old composts and in the 2nd year 18-month-old composts were used. Plants cultivated in 7-month-old composts showed better growth-related parameters, created more inflorescences and were more decorative than those cultivated in 18-month-old ones. The medium with compost consisting of 70% sewage sludge and 30% straw gave the best results. Composts application increased nutrients and heavy metals content in pelargonium leaves. Heavy metals content was definitely lower than the value considered toxic to plants.

The results were obtained from three-year trials on two locations. TGA levels in tubers' flesh ranged from 33.69 to 167.77 mg/kg fresh matter (FM), and the ratio of α-chaconin to α-solanin from 1.18 to 3.78. No TGA safety limit was exceeded for any cultivar. The glycoalkaloids content was not significantly influenced by flesh colour, whereas the cultivar genotype had a decisive influence on their content. Eight cultivars with coloured flesh yielded a more favourable lower TGA content in comparison with the yellow-fleshed control cv. Agria (86.3 mg/kg FM); on the contrary six cultivars showed higher TGA values. The highest average TGA content was found in the purple-fleshed Bora Valley cultivar (165 mg/kg FM), the lowest was found in the red-fleshed Red Emmalie cultivar (43.6 mg/kg FM), whereas the white-fleshed cv. Russet Burbank reached 67.0 mg/kg FM. The glycoalkaloid content was significantly affected by location and year weather conditions.

A greenhouse pot experiment was conducted with spring wheat. The soils were extracted with the following methods/extractants: H2O, CaCl2, LiCl, iron oxide impregnated filter papers (Fe-oxide Pi), Olsen, calcium-acetate-lactate (CAL), cation and anion exchange membranes (CAEM), Mehlich 3, Bray and Kurtz II (Bray II), citrate-bicarbonate-dithionite, organic P, HCl, acid ammonium oxalate, total P. Plant P uptake was in the range of the P extracted by neutral salt solutions (CaCl2, LiCl). P extracted with H2O, CaCl2 and CAEM correlated best with plant P uptake over one growing season, while several established soil P test methods, including CAL, Mehlich 3 and Bray II, did not show significant correlations. When grouping the soils according to pH, the weaker extraction methods (H2O, CaCl2, LiCl) showed significant correlations with plant P uptake only for the low and intermediate pH groups (pH in 1 mol/L KCl ≤ 6.6), while some of the stronger extraction methods (CAL, Mehlich 3, Bray II, dithionite, oxalate, total P) showed significant correlations only for the high pH group (> 6.6) comprised of calcareous soils. It was concluded that weaker P extraction methods, especially neutral salt solutions best predict plant-available P in the short term. However, they do not perform well for calcareous (and clayey) soils and do not account for P that may become available beyond one growing season.
