Full textQuebec produces 87% of lettuces and 38% of onions in Canada, mostly in organic soils, but the nitrogen fertilization of these crops is difficult to manage. Inadequate nitrogen intake regardless of local conditions can generate nutritional imbalances in the plant and increase the risk of contamination of surface and ground waters. Our objective was to develop nutrient diagnostic models and N recommendations for lettuce and onion according to the contents of C and N in the soil and to balances between macronutrients in leaf tissues. Twenty-four and thirteen nitrogen fertilization trials were conducted on lettuce and onion crops, respectively, in organic soils of southwestern Quebec from 2002 to 2006. Every crop received four doses of N from zero to 150-180 kg N ha-1 applied before planting or split-applied. To account for interactions between elements, the results of C and N analyses in soils and N, P, K, Ca and Mg analyses in leaf tissues were completed by a filling value (Fv) to close the compositional vector then transformed into log isometric ratios (ILRs). Because ILRs are orthogonal to each other, a Mahalanobis distance (M^2) can be computed from a reference composition. The ILRs were calibrated against crop response and classified into soil groups by meta-analysis for soil analyses, as "True Negatives" (TN), "True Positives" (TP), "False negatives" (FN) and "False Positives" (FP) specimens by the Cate-Nelson method in the case of foliar analyses. A Mahalanobis distance (M^2) was computed between experimental ILRs and reference ILRs. We delineated three groups of soil fertility for lettuce about M^2 values of 1.0 and 5.5 to conduct meta-analysis using response ratio as effect size. For onion, we delineated two groups about the M^2 value of 5.5. The M^2 values of 8.4 and 19.6 were the upper limits for recommendation models N for lettuce and onion, respectively. We obtained a quadratic model for lettuce and a linear model for onion. Balance standards of nutrients were elaborate at from foliar analyses high yield for lettuce and onion using Cate-Nelson analysis. Nutrient interactions were arranged in a dendrogram. Yield critical thresholds were 44 Mg ha-1 for lettuce and 50 Mg ha-1 for onion. Mahalanobis distances of 3.09 and 3.03 delineated critical balance of imbalance for lettuce and onion, respectively. The ILR transformation technique showed greater diagnostic accuracy than DRIS, evaluated in 78% for lettuce and 87% for onion. Balance [Fv

Full textCloudberry present low and variable fruit yields that are probably explained by the oligotrophy of the ombrotrophic peatlands where it grows. Two different fertilization techniques were tested in two natural bogs of the Quebec Lower-North-Shore. An organo-mineral fertilizer (crab and fish meal, potassium chloride) was applied annually in soil for three years. Foliar applications of boron and copper were tested during the third year. The fertilizers had no effect on cloudberry growth and productivity and the organo-mineral fertilizer hardly mineralized and dispersed in the soil. Mineralization capacity of other organic fertilizers in natural peatlands should thus be tested. Boron and copper are abundant in the fruits and are likely limiting fruit production, but new trials are needed to confirm it. In conclusion, more information on the nutrient requirements of cloudberry is needed to select suitable fertilizers.

Full textThis dissertation demonstrates that motion blurred images acquired in the vicinity of the spinning disc of a fertiliser centrifugal spreader can be used to estimate the outlet velocity components of the granules. First, a recursive linear filter is applied to the image to detect the streak axes corresponding to the granule trajectories. This filter was specifically developed for our research by means of the Canny method and an edge model based on an experimental approach. Secondly, the trajectories are identified and characterised using the Hough Transform. Its computation is based on mechanical knowledge derived from spreading analysis. Next, the outlet velocities are deduced from the outlet angle measurements using kinematic relationships. The fertiliser angular distribution is also estimated using the frequency of trajectory identifications in the image. Finally, the spread pattern is computed by means of a ballistic flight model using the above parameters
