The investigations were carried out in two permanent fertilization experiments established in 1955 on the black earth in Chylice, near Warsaw, Mazovian province, Poland. The aim of this study was to compare the impact of long-term mineral (NPK); organic (FM) and mixed mineral-organic (1/2 NPK + 1/2 FM) fertilization in two crop rotations on some soil physical properties, including the soil structure, dry bulk density, soil moisture and field water capacity. The fertilization systems and using red clover in crop rotation significantly influenced soil structure and water conditions. Farmyard manure (FM, 1/2 NPK + 1/2 FM) application in both crop rotations...

Magnesium (Mg) budgeting was conducted on a production farm at Górzno, Poland during the 2004-2007 growing seasons for 15 crop sequences: nine with oil-seed rape (OR) and six with maize grown for grain or silage (SM) as dominant crops. The impact of cropping sequences (CS) on Mg management was evaluated using two methods: soil surface balance, and soil system balance. The Mg yield output ranged from 4.5-17 kg Mg/ha, but including harvest residues from 8.9-22.9 kg Mg/ha. The average quantity of external Mg, required to balance its yield output reached 5.8 kg/ha in the OR-CS and 10.4 kg/ha in the SM-CS. The net Mg input, through mineral fertilizer, farmyard...

The surface carbon dioxide (CO2) fluxes together with the soil microbial biomass and activity in undisturbed soil columns were studied in three growing seasons. Soil columns had six treatments: (1) control without plants; (2) mineral fertilized without plants; (3) no fertilizer and maize plants; (4) mineral fertilized and maize plants; (5) manure and maize plants; (6) mineral fertilized plus manure and maize plants. Soil microbial biomass was measured by substrate-induced respiration (SIR) and microbial activity as fluorescein-diacetate hydrolysing activity (FDA). Treatments had a significant effect (P < 0.001) on CO2...

The aim of this work was to evaluate the changes of different soil sulfur forms during long-term field experiments supplied with sewage sludge (SS), farmyard manure (FYM) or mineral fertilizers. The experiment was established at three different sites with the crop rotation of potatoes, wheat and barley. Fertilizing system was based on the same nitrogen dose per the whole crop rotation. Soil samples from the beginning of the experiment (1996) and at the end of each crop rotation were analysed after all three crops harvest. Similar tendencies of changes in water extractable (Sw), adsorbed (Sads), 1 mol/L HCl estimated (SHCL)...

Stable isotope 15N tracer technique was used in combination with artificial rainfall simulation to study the influence of interflow and surface-flow on nitrogen (N) migration loss of soil-plant systems on typical red soil sloping uplands. This study also investigated the utilization efficiency of fertilizer N during different peanut plant growth stages. The results indicated that soil N loss was predominantly via interflow and erosive sediment. Fertilizer N loss during the initial growth stage was mainly through surface runoff, while that occurred as interflow increased from less than 5% to around 16% during the middle and late growth stages....

Soybean yields can be considerably improved by inoculation with selected Bradyrhizobium japonicum strains and foliar fertilization. An exact field experiment was carried out in 2012-2014 at the Experimental Station of Cultivar Assessment in Przecław, Poland. The test plant was soybean cv. Aldana. The experimental factors were: bacterial inoculant Nitragina (Bradyrhizobium japonicum); foliar fertilization with Mikrokomplex; combined applications Nitragina + Mikrokomplex and the control treatment. Significant effect of Nitragina on an increase in the number of plants prior to harvest, plant height and the number of pods per...

Bensulfuron methyl (BSM) is applied in rice to control a wide range of weeds due to low application rate and high efficiency. A study was conducted to evaluate residues of BSM in soil and rice plant at different doses as pre- and post-emergence application in transplanted rice. The quick easy cheap effective rugged safe (QuEChERS) method was evaluated for BSM residue extraction from different matrices. The limit of detection and limit of quantification was 0.005 and 0.01 µg/g, respectively in soil and rice plant. The average BSM recovery of 91.1, 82.8, 84.5 and 88.7% was obtained from soil, rice straw, grain and husk, respectively. Though, BSM...
