“…(Bell et al, 2015). Similarly, Louro et al (2015) reported no significant fertiliser formulation effect on N 2 O emissions. In contrast, Dobbie and Smith (2003a) observed lower N 2 O emissions associated with urea application compared to ammonium nitrate (AN).…”

The application of nitrogen (N) fertilisers to agricultural soils is a major source of nitrous oxide (N 2 O) emissions. The Intergovernmental Panel on Climate Change (IPCC) has set a default emission factor of 1% (EF 1) for N fertiliser applied to managed agricultural soils. This value does not differentiate between different N fertiliser formulations or rates of N application. The objective of this field study under spring barley was to determine N 2 O EF's for different N fertiliser formulations including urea and urea stabilised with the nitrification inhibitor dicyandiamide (DCD) and/or the urease inhibitor N-(n-butyl) thiophosphoric triamide (NBPT) and to evaluate their N 2 O loss abatement potential relative to calcium ammonium nitrate (CAN). The highest EF 1 measured was 0.49% for CAN which was less than half the IPCC default value of 1%. While the urease inhibitor did not reduce emissions relative to CAN; the nitrification inhibitor significantly reduced emissions compared to CAN with EF 1 as low as 0.00% for a typical spring barley site. There was no significant impact of CAN or urea application rate on EF 1 but there was a significant negative relationship 2 observed for urea in 2013. The study highlights the importance of generating higher Tier emission factors in terms of fertiliser type for use in national inventories.

“…Te nitrate concentration in cabbage leaves was determined using a segmented fow analyzer AA II (Bran + Luebbe, Norderstedt, Germany) at 540 nm after reduction in a copper-covered cadmium column (NO 3 − + 2e-® NO 2 − ) to generate a diazo compound, as described by Kmecl et al [33] and Louro et al [34].…”

Moringa leaves contain a proper amount of antioxidants, amino acids, vitamins, hormones, macronutrients, and micronutrients. Therefore, it is applied as a natural, inexpensive, and simple-to-make biostimulant to boost nutritional value and growth parameters in a variety of plants. The main purpose of this study is to determine the optimal concentration of Moringa oleifera L. leaf extract (MLE) as an effective biostimulant to improve nutritional and physical quality in cabbage (Brassica oleracea var. capitata). To do this, three concentrations of MLE (6, 8, and 10%) were foliar sprayed to the plant leaves at a rate of 25 mL plant−1 for every two weeks from transplantation till harvest, while control plants (Ø) were sprayed with distilled water only. Our results show that MLE greatly increased cabbage growth, nutrient content, pigment content, and nutrient absorption, while a high concentration of 10% MLE could also significantly reduce nitrate content in cabbage leaves. In comparison to the control plants, sprays of 6%, 8%, and 10% MLE reduced nitrate content by 23%, 14%, and 12%, respectively. However, the lowest nitrate content was found for the plants sprayed with 6% MLE. Except for the dry matter, all the growth parameters, mineral content, and pigment content were significantly higher after spraying with 10% MLE, while better vitamin C and lower nitrate were found in the plants treated with 6% MLE. A Pearson correlation reveals that head weight has a positive correlation with head diameter, head height, chlorophyll a, and carotenoids at p levels of 0.01 and a positive correlation with chlorophyll b and vitamin C at p levels of 0.05. Vitamin C and dry matter, on the other hand, had a negative connection with nitrate content.
