“…Additionally, fertilizerderived N treatments were established to serve for comparison to the broccoli residue-derived N treatments. In incubation studies, mineral N is typically added to establish sufficient SMN levels for microbial decomposition, such as in Rashid and Voroney (2004). Thus, to investigate the timing of broccoli residue N mineralization in relation to the microbial N requirement for organic C decomposition, the fertilizer-derived N treatments included: fertilizer only (with 34 mg of NH 4 NO 3 ), 268 mg of dry broccoli residue '34 mg of NH 4 NO 3 , and 34 mg of NH 4 NO 3 'each OCA, at the respective, aforementioned rate.…”

Congreves, K. A., Voroney, R. P., O'Halloran, I. P. and Van Eerd, L. L. 2013. Broccoli residue-derived nitrogen immobilization following amendments of organic carbon: An incubation study. Can. J. Soil Sci. 93: 23Á31. Cole crops, compared with many other crops, can pose a high risk of N losses after harvest due to substantial quantities of readily mineralizable N in crop residues. Organic C amendments (OCA) may reduce N losses via immobilization; however, the synchrony of OCA decomposition and cole crop residue N mineralization is crucial. A soil incubation study evaluated net N and C mineralization of broccoli residue-derived N or fertilizer-derived N with three OCAs: wheat straw, yard waste, or used cooking oil, to predict N immobilization and the potential to mitigate post-harvest N losses. By the 56th d of incubation, broccoli residue mineralized 67.0 mg N kg (1 . In the broccoli residue-derived N treatments, wheat straw, yard waste, and used cooking oil significantly reduced the quantity of net N mineralization by 16.9, 12.3, and 86.0 mg N kg (1 , respectively. The net N mineralization data were fitted to a first-order exponential model, and the overall trend of OCA was negative, indicating immobilization, whether N was derived from broccoli residue or fertilizer. The order of effect from OCAs on N immobilization corresponded to the order of effect on net C mineralization, where wheat straw and yard waste were lower than used cooking oil. In broccoli residue treatments, compared with fertilizer, higher N immobilization occurred for used cooking oil, and higher net C mineralization occurred for used cooking oil and yard waste. The higher N immobilization and net C mineralization suggest that broccoli residue produced a synergistic effect on the decomposition of used cooking oil. Additionally, both broccoli residue and used cooking oil treatments had synchronous peaks of net C mineralization at 4 d. This study provides evidence to warrant field studies to confirm that the application of organic C, especially used cooking oil, after cole crop harvest may be a beneficial management practice to minimize soil N losses.Key words: Post-harvest, cole crops, wheat straw, yard waste, used cooking oil, nitrogen and carbon dynamics Congreves, K.

“…Unlike sewage sludge and many other organic amendments which can contain significant amounts of N, phosphorus, potassium, or other nutrient materials, GTW contains large amounts of readily degradable C compounds but very little of the nutrients required for plant or microbial growth (Rashid and Voroney 2004); thus, this may lead to an imbalance in C and other essential nutrients creating negative effects on soil bacterial community. Evidently, our results have major implications for developing sound regulatory guidelines for the use of GTW in agriculture by indicating which types of GTW are unsuitable for application in the agricultural soils due to their significant negative effects on soil bacterial community.…”

“…Soil 1 Background, aim, and scope Grease trap waste (GTW) is an organic waste collected and pumped out of grease traps in wastewater drains in restaurant areas in cities to reduce the concentration of fat and suspended solids in the wastewater. Because the potential benefit of GTW as a source of organic matter and soil conditioner containing no/low amounts of metals or pathogenic organisms (Rashid and Voroney 2004), current Australian legislation permits the beneficial application of the GTW into agricultural soil. However, little is known about the influence of GTW on soil bacterial community.…”

Abstract:Cole crops (Brassica vegetables) can pose a significant risk for N losses during the post-harvest period due to substantial amounts of readily mineralizable N in crop residues. Amending the soil with organic C has the potential to immobilize N and thereby reduce the risk for N losses. Four field trials were conducted to determine the effects of organic C amendments (OCA) on N dynamics and spring wheat (Triticum durum L.) harvest parameters proceeding early-and late-broccoli (Brassica olecerea var italica L.) systems in 2009 and 2010. The experimental controls represented the traditional grower practice of incorporated broccoli crop residue (CR-control) and the pre-plant application of N fertilizer (CRN-control) to subsequent spring wheat. Alternative practices were compared to the controls, which included broccoli crop residue removal (CR-removal), an oat (Avena sativa L.) cover crop (CC-oat), and three different OCA of wheat straw (OCA-straw), yard waste (OCA-yard), or used cooking oil (OCA-oil). The treatments, which demonstrated reduced autumn soil mineral N (SMN) concentrations after broccoli harvest, relative to the CR-control, were CR-removal, OCA-straw, and OCA-oil. Although CR-removal and OCA-straw indicated a reduced potential for autumn soil N losses in the early-broccoli system, these practices are not recommended for growers because subsequent spring wheat yield and profit margins were reduced compared to the CR-and CRN-controls. The OCA-oil reduced autumn SMN concentrations by 53 to 112 kg N ha relative to the CR-control after both early-and late-broccoli harvest, suggesting a larger potential for reduced autumn soil N losses, compared to all other treatments. No detrimental effects resulted from the OCA-oil OPEN ACCESSAgronomy 2013, 3 182 treatment on the subsequent spring yield or grain N. The OCA-oil reduced spring wheat profit margins relative to the CR-control, like the OCA-straw and CR-removal treatments, however profit margins were similar between the OCA-oil and the CRN-control. Therefore, in areas with a high risk of environmental N contamination, growers should consider the OCA-oil practice after cole crop harvest to minimize the risk of N losses.
