“…The quantity of nitrates on non-fertilized object after plant harvesting was twice lower than on the objects fertilized with a dose of 160 kg N•ha -1 . Abad, et al, (2004) revealed a similar dependence in cultivation of durum wheat fertilized in the range of 0-200 kg N•ha -1 and Richards, et al, (1996) in winter barley cultivation. Despite its good availability to plants, NO 3 accumulates in soil due to nitrification process which is most intensive during vegetation period.…”

The effect of nitrogen dose and application of soil properties improving microbial preparations on the content of mineral nitrogen in soil after spring wheat harvesting were evaluated in a three-year field experiment. The investigations were conducted under conditions of Luvic Chernozem. Diverse nitrogen fertilization (0, 40, 80, 120 and 180 kg. ha-1) was applied and microbial preparations: Proplantan AM, Effective Microorganisms EM and UGmax Soil Fertilizer. The content on N min in the soil after wheat harvesting, particularly in the upper layers of the soil profile was growing with increasing nitrogen fertilization level. The amount of nitrate nitrogen in the soil after harvest plants was below the average content of N-NO3 for this category of agronomic soil in Poland. Bigger quantity of mineral nitrogen in soil after plant harvesting than before their sowing was registered only on the obejcts receiving 160 kg N. ha-1 in the years characterized by a similar to multiannual average amount and distribution of rainfall during the period from April to June. Microbial preparations Proplantan AM and Effective Microorganisms EM caused a significant decrease in nitrate and ammonium nitrogen in the 0-30 and 30-60 cm soil layers.

Biofertilizers have been widely used in many countries for their benefit to soil biological and physicochemical properties. A new microbial biofertilizer containing Phanerochaete chrysosporium and Bacillus thuringiensis was prepared to decrease nicotine content in tobacco leaves by regulating soil nitrogen supply. Soil NO-N, NH-N, nitrogen supply-related enzyme activities, and nitrogen accumulation in plant leaves throughout the growing period were investigated to explore the mechanism of nicotine reduction. The experimental results indicated that biofertilizer can reduce the nicotine content in tobacco leaves, with a maximum decrement of 16-18 % in mature upper leaves. In the meantime, the total nitrogen in mature lower and middle leaves increased with the application of biofertilizer, while an opposite result was observed in upper leaves. Protein concentration in leaves had similar fluctuation to that of total nitrogen in response to biofertilizer. NO-N content and nitrate reductase activity in biofertilizer-amended soil increased by 92.3 and 42.2 %, respectively, compared to those in the control, whereas the NH-N and urease activity decreased by 37.8 and 29.3 %, respectively. Nitrogen uptake was improved in the early growing stage, but this phenomenon was not observed during the late growth period. Nicotine decrease is attributing to the adjustment of biofertilizer in soil nitrogen supply and its uptake in tobacco, which result in changes of nitrogen content as well as its distribution in tobacco leaves. The application of biofertilizer containing P. chrysosporium and B. thuringiensis can reduce the nicotine content and improve tobacco quality, which may provide some useful information for tobacco cultivation.
