Integrated nutrient management (INM) effects chemical transformation of nutrients in soil and plant uptake. This study present the long-term (30 years) effects of integrated nutrient management on zinc (Zn) fractions and rice yield. The treatments include ten combinations of nitrogen, phosphorous and potassium applied through mineral fertilizers and substituted through farmyard manure (FYM), green manure (GM) and wheat cut straw (WCS).The distribution of Zn into exchangeable (EXCH), carbonate bound (CARB), organic matter bound (OM), manganese oxides bound (MnOX), amorphous iron oxide bound (AFeOX) and crystalline iron oxide bound (CFeOX) was determined. The effect of long-term use of mineral fertilizers on EXCH-Zn was not significant as compared to control, however, EXCH-Zn increased significantly in INM treatments compared to both control and mineral fertilizer in surface soil (0-15 cm). Similarly, CARB-Zn and OM-Zn was significantly higher in INM as compared to control and mineral fertilizer treatments. The distribution of Zn in MnOX, AFeOX and CFeOX fractions was not distinctly affected with long-term fertilizations. In general, concentration of Zn fractions was lower in subsurface soils (15-30 cm) as compared to surface soils. The grain yield of rice increased in order control< mineral fertilizers <INM treatments. The highest grain yield (71.8 q ha-1) was recorded in INM treatment where 25% of the recommended NPK were supplied through GM. The positive and significant correlation of EXCH-Zn (r = 0.714), CARB-Zn (r = 0.601) and OM-Zn(r = 0.648) fractions and Zn uptake in grain showed that the plant availability of Zn depends upon these fractions in soils.

Abstract We investigated the role of Mn oxides on the soil structure (contents of dry and water-stable aggregates) of sandy soil under a controlled long-term fertilisation experiment. We examined two experiments: a 94-year-term experiment with: no fertilisers, NPK fertilisers, and CaNPK fertilisers; and a 25-year-term experiment that included: farmyard manure and no mineral fertilisation, farmyard manure + NPK fertilisers, and farmyard manure + CaNPK fertilisers. The results showed that in the 94-year-term trial, Mn oxides were increased in CaNPK treatment. In the 25-year-term experiment, the farmyard manure combined with NPK decreased total Mn and its oxides. In the 94-year-term experiment, the content of dry-sieved macro-aggregates (DSAma) and water-stable macro-aggregates increased due to fertilisation. The result of our study suggests that Mn oxides had positive effects mainly on higher size classes of DSAma and did not have any effect on water-stable aggregate contents.

Little attention has been paid to the effect of long-term fertilizer application on concentrations of elements in grain of barley produced on the metal non-contaminated agricultural soil. In 2010, we analyzed yield and concentrations of elements in grain of spring barley in unfertilized control, mineral fertilizer application (N<sub>4</sub>P<sub>2</sub>K<sub>2</sub> &ndash; 70, 60 and<br />100 kg N, P and K per ha) and combinations of farmyard manure or poultry litter with mineral fertilizer (FMN<sub>4</sub>P<sub>2</sub>K<sub>2</sub> and PLN<sub>4</sub>P<sub>2</sub>K<sub>2</sub>) treatments in the Ruzyně Fertilizer Experiment established on Luvisol in 1955 in Prague (Czech Republic). The yield of grain ranged from 4.03 to 9.74 t/ha in the control and FMN<sub>4</sub>P<sub>2</sub>K<sub>2</sub> treatment. There was a positive effect of fertilizer application on concentrations of nitrogen, phosphorusand potassium, but no effect on concentrations of calcium and magnesium. With the exception of iron, concentrations of micro (copper and zinc) and risk elements (arsenic, cadmium, chromium, lead, manganese and nickel) were not significantly affected by the fertilizer treatments. Long-term use of organic and mineral fertilizers with appropriate application rates does not represent any risk for contamination of barley grain by risk elements on mineral rich and metal non-contaminated agricultural soils.

A field experiment established in 1962 on a luvisol derived from loess was chosen to investigate the effect of long-term application of farmyard manure, compost and sewage sludge, respectively, in two increments on inorganic and organic S fractions in bulk soil. Compared with mineral fertilizer, the high application rates of the different organic fertilizers (10 t farmyard manure (FYM2), 29 t compost (COM2), 7.44 t sewage sludge (SS2)/ha/year, respectively), resulted in an increase of the total S content in the bulk soil: 220 mg/kg (FYM2), 298 mg/kg (COM2), 277 mg/kg soil (SS2) as compared to the control (MIN) with 158 mg/kg soil. The sum of water soluble plus adsorbed S was significantly higher in the treatments with the high amount of compost (17.9 mg/kg soil) and sewage sludge (16.4 mg/kg) soil as compared to all the other treatments (10.0 to 13.1 mg/kg soil). The treatments with the high amounts of organic manures contained lower contents of ester sulfate and higher contents of C-bonded S as compared to the treatments with the low amounts, and vice versa. &nbsp; &nbsp;
