Potential Phosphorus Export in Snowmelt as Influenced by Fertilizer Placement Method in the Canadian Prairies

A 3-yr study was conducted in eastern Wyoming from 1995 to 1997 to evaluate the effect of fertilizer placement on jointed goatgrass competitiveness with winter wheat. Fertilizer placement methods consisted of applying 45 kg/ha of nitrogen (50% as urea and 50% as ammonium nitrate) in a deep band 5 cm below and 2.5 cm to the side of the wheat row, broadcasting on the soil surface, or injecting fertilizer by spoke wheel 10 cm deep and 5 cm to the side of the wheat row. Neither fertilizer placement nor jointed goatgrass presence affected winter wheat stand. Wheat yield reductions from jointed goatgrass competition were 7 and 10% higher with the broadcast than deep-band or spoke-wheel injection methods, respectively. Wheat spikes/plant, seeds/spike, 200-seed weight, and plant height were not influenced by fertilizer placement; however, the presence of 35 jointed goatgrass plants/m2reduced spikes/plant 21%, seeds/spike 12%, and 200-seed weight 6%. Jointed goatgrass populations were not influenced by fertilizer placement method; however, the number of spikes/plant was reduced 8 and 10%, joints/spike 3%, and biomass 15 and 21% by deep band or spoke wheel fertilizer placement.

The Face

Ensuring sustainable agricultural production technologies is becoming increasingly important in the face of the observed climate change and need to reduce the harmful environmental impact of agriculture. The aim of the study is a comparative assessment of the deep fertilizer placement method with surface broadcast application of fertilizers as regards overall sustainability. To reach this goal, based on the results of field experiments and expert opinions, the values of sustainability indicators (economic, environmental and social aspects) were determined. The AHP (analytical hierarchy process) method was applied to comparative assessment. The conducted analysis showed that economic, environmental and overall sustainability assessment are conditioned by productivity achieved. In the first year of the experiment, when the yield increase was not achieved, in terms of sustainability criteria considered, the surface broadcast application of fertilizers was determined to be preferred as compared to the deep fertilizer placement method. On the other hand, in the second year of research with yield increase, the practice with the deep application of mineral fertilizers resulted in a better performance than surface broadcast fertilization, while showing a similar overall performance in the case of natural fertilizers.

Better Than

Areca palms (Dypsis lutescens [(H. Wendl.) Beentje and J. Dransf.]) were transplanted from containers or a field nursery and were treated with fertilizer placed at the bottom of the planting hole, incorporated into the backfill, or on the surface of the root ball to determine the effects of fertilizer placement at planting on palm growth and quality. Fertilizer was applied at 0, 250 g (20 g N), or 500 g (40 g N) per tree for each placement method to determine fertilization rate effects. Areca palms transplanted from containers grew best when fertilizer was incorporated into the backfill, but any fertilizer placement or rate was better than no fertilizer. When areca palms were transplanted from a field nursery, there was no consistently best fertilizer placement method. However, fertilized plants grew better and had less severe nitrogen and potassium deficiency symptoms than unfertilized palms. There was no benefit to higher fertilization rate for either container- or field-grown areca palms.
