“…a reduced quantity of easily oxidizable C or available N remained after 21 d, which triggered microbial death and turnover in the broccoli residue-derived N with the used cooking oil treatment. The pattern of N immobilization followed by re-mineralization with cooking oil was consistent with other laboratory (Smith 1974) and field (Rashid and Voroney 2003) studies. If the period of N immobilization coincides with periods of high risk for N losses in the field, a reduction in N losses may result.…”

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.

“…A pattern of N immobilization followed by re-mineralization with used cooking oil or "fat oil grease" amendments has been found in previous laboratory [11] and field [26] research. In the present study, N immobilized in the OCA-oil after broccoli harvest in autumn could have re-mineralized for the subsequent spring wheat plant uptake.…”

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.

“…Leaf greenness is influenced by a number of factors (hybrid, stage of growth and nutrients), but soil N availability most probably has the greatest effect within a field (Blackmer and Schepers 1995). Soil available N (NO 3 -N) was immobilized during the decomposition of FOG and net N immobilization was significantly higher in SFOG amended plots compared to FFOG amended plots (Rashid and Voroney 2003).…”

Rashid, M. T., Voroney, P. and Parkin, G. 2005. Predicting nitrogen fertilizer requirements for corn by chlorophyll meter under different N availability conditions. Can. J. Soil Sci. 85: 149-159. Nitrogen management strategies that enhance fertilizer use efficiency and maximize profitability in corn require a rapid and accurate method to determine the crop N needs of current hybrids. The objective of this study was to evaluate the potential of a portable chlorophyll meter for predicting N fertilizer requirements for corn grown under varying levels of N availability. Several crop management treatments were imposed in an attempt to create conditions ranging from low N availability (oily food waste application in spring and fall, application at different rates in spring) to high N availability (continuous fertilized corn, winter wheat cover crop). Different corn hybrids were sown at different sites (21 site yr) and varying N fertilizer application rates were applied. Chlorophyll meter readings (CMR) were taken at the 5th to 6th leaf stage (V 6 ) using a SPAD-502 chlorophyll meter. The crop management treatments, corn hybrids and their interaction significantly affected the chlorophyll meter readings. A high inverse correlation between chlorophyll meter readings and maximum economic rate of nitrogen (MERN) was observed (r = -0.87). The main new and unique aspect of our research is the development of a linear model for using chlorophyll meter measurements to make N fertilizer recommendations (MERN = 348.47 -8.5304 × CMR) for corn production under varying degrees of N availability in Southern Ontario. L'étude devait évaluer l'utilité d'un appareil portatif servant à doser la chlorophylle pour établir les besoins en engrais N du maïs cultivé dans des sols contenant une quantité variable de N assimilable. Les auteurs ont recouru à diverses pratiques culturales pour engendrer les conditions voulues, soit une faible (application de déchets alimentaires huileux au printemps et à l'automne, variation du taux d'application au printemps) à une grande quantité (fertilisation continue, culture-abri de blé d'hiver) de N disponible. Ils ont semé divers hybrides de maïs à différents endroits (21 sites-années) et appliqué un taux variable d'engrais azotés. Ensuite, ils ont dosé la chlorophylle au stade de la 5 e -6 e feuille (V 6 ) avec un lecteur SPAD-502. Les pratiques culturales, l'hybride et leurs interactions affectent significativement les relevés. Les résultats obtenus avec le lecteur présen-tent une très forte corrélation inverse avec le taux d'application maximal économique d'engrais azoté (TAME) (r = -0,87). La principale innovation et le caractère unique de cette étude consistent en l'élaboration d'un modèle linéaire utilisant la concentration de chlorophylle pour formuler des recommandations sur l'application d'engrais azotés (TAME = 348,47 -8,5304 x quantité de chlorophylle) pour la culture du maïs selon la quantité de N disponible dans le sud de l'Ontario.
