Although composted liquid pig manure is increasingly being applied to agricultural soils, little is known about its impacts on N dynamics (mineralization, denitrification, immobilization, and plant uptake) in the crop root zone compared to liquid pig manure (LPM) or other types of composts. A greenhouse pot experiment was conducted to determine N mineralization and plant uptake in a ryegrass-cropped clay loam soil that had been amended with either LPM, LPM + wheat straw compost (PMS), or yard waste compost (YWC). Over a 20-wk growth period, plant biomass was increased relative to the control by 164% for LPM, 64.3% for YWC, and 39.6% for PMS. However, the recovery of amendment N in the ryegrass was low and variable at 3.3% for PMS (12.7 mg N kg-1), 3.7% for YWC (21.5 mg N kg-1), and 15.3% for LPM (90.9 mg N kg-1). Although gains and losses of mineral N occurred primarily within the first 8 wk, assimilation of amendment N by the ryegrass appeared to continue throughout the entire growth period. High amounts of inorganic N present in the LP M treatment led to the greatest loss of N, as N2O, through denitrification and nitrification (39.1 mg N kg-1). This was 35 times greater than the YWC treatment (1.1 mg N kg-1), over 50 times greater than the N2O loss from the PMS treatment (0.7 mg N kg-1) and over 76 times greater than the N2O loss from the control (0.5 mg N kg-1). There was a net gain in mineral and plant assimilated N from mineralization with the control (6.4 mg N kg-1) and YWC treatments (8.8 mg N kg-1) over 20 wk. However, there was a small decrease in mineral and plant assimilated N with the PMS treatment (4.3 mg N kg-1) and a large decrease with the LPM treatment (90.1 mg N kg-1). From an environmental perspective, the large amount of N2O generated by the LPM treatment compromises the usefulness of LPM as a source of crop-available N.

Carbon And Nitrogen Stocks

Yang, X., Reynolds, W. D., Drury, C. F., Fleming, R., Tan, C. S., Denholm, K. and Yang, J. 2014. Organic carbon and nitrogen stocks in a clay loam soil 10 years after a single compost application. Can. J. Soil Sci. 94: 357–363. Household food waste compost (FWC), yard waste compost (YWC) and pig manure plus wheat straw compost (PMC) were applied once in the fall of 1998 to a Brookston clay loam soil in southwestern Ontario to determine immediate and long-term effects of organic amendments on soil quality and productivity. In this report, we describe the residual effects of these single compost applications on soil organic carbon (SOC) and total soil nitrogen (TN) stocks 10 yr after compost addition (2009). FWC was applied at 75 Mg ha−1, 150 Mg ha−1 and 300 Mg ha−1, while YWC and PMC were applied at the single rate of 75 Mg ha−1. The 75 Mg ha−1 additions of YWC, PMC and FWC increased SOC in the top 30 cm relative to a control (no compost additions) by 12.3% (9.0 Mg ha−1), 16.6% (12.2 Mg ha−1) and 0%, respectively; and they increased TN relative to the control by 8.0% (0.53 Mg ha−1), 11.7% (0.77 Mg ha−1), and 0%, respectively. The 150 and 300 Mg ha−1 additions of FWC increased SOC in the top 30 cm by 13.0 and 24.7 Mg ha−1, respectively, and they increased TN by 0.93 and 1.70 Mg ha−1, respectively. These results indicate that increases in SOC and TN stocks accruing from a single compost addition can persist for at least a decade, but the degree of increase depends strongly on compost type and addition rate. It was concluded that high compost addition rates of FWC and/or addition of composts derived from recalcitrant organic materials may be a good strategy for achieving long-term carbon and nitrogen sequestration in the cool, humid fine-textured soils of southwestern Ontario.

Beneficial microorganisms play a key role in the availability of ions minerals in the soil and use Randomized Complete Block Desing ( R.C.B.D ). The objective of this paper to the study effect of the of biofertilizer and miniral treatments on availability of NPK for crop corn zea mays L.Two types of biofertilizer are Bacterial Bacillus subtilis and Fungal Trichoderma harianum. Three levels of potassium fertilizer are (2.9533, 0.4000 and 2.9533). A field experiment in fall season of 2018 Has been conducted in silty clay loam soil. The experimental Results indicated that Bacillus and Trichoderma inoculation separately or together Have made a significant effect to increase in the availability of N P K in the soil compare to other treatments. The grain yield is where (2.9533, 0.4000 and 2.9533) of bacterial and fungal bio-fertilizer and potassium fertilizers respectively as compared to the control.
