The effect of MSW compost and fertilizer on extractable soil elements and the growth of winter squash in Nova Scotia

The Effect of MSW Compost and Fertilizer on Extractable Soil Elements, Tuber Yield, and Elemental Concentrations in the Plant Tissue of Potato

“…Warman and Havard (1998), however, found no tuber yield differences between fertilizer and composttreated plots in two of 3 years of a 3-year study on the exactly same sandy loam, although they did not use MSW compost. We noted the NPK treatment was also found to produce the highest yields of squash and sweet corn in the two associated studies performed at the same time (Warman et al 2009;unpublished research).…”

“…The MSW2 plots had the highest concentrations of S and Zn in the shoots, and all compost treatments had significantly higher shoot Cu than the NPK plots (Tables 5 and 6). Copper was also highest in MSW3 treatments (Warman et al 2009). Somewhat in contrast, whole plant Cu concentration of corn plants in 1998 was highest in the MIX treatment (Warman et al unpublished).…”

“…The MSW3 treatment resulted in the highest concentrations of extractable K, Ca, S, Cu, Zn, and Na in the surface horizon, and in soil Na at the lower depth (Table 4). In plots planted with the two other crops of this three-crop rotation study, the soil samples from the 0-15 cm soil depth showed that the MSW3 treatment produced the highest levels of Ca, Mg Cu, Mn, Zn, B, and Na in corn plots and K, S, Cu, Zn, B, and Na in squash plots; only B and Na in corn plots and Na in squash plots were influenced by treatments in the 15 to 30 cm soil depth in the last year of those studies (Warman et al 2009;unpublished research). Sodium, therefore, was the only element that consistently moved down the profile following MSW compost additions.…”

“…Phosphorus uptake was generally higher in the NPK and mixture treatments than in any treatment involving only MSW compost. This paper is the third of a series from a 3-year, three-crop rotation; the results of using MSW compost on squash (Warman et al 2009) and sweet corn (unpublished research) have been described. This paper examines tuber yields and a full range of extractable soil and potato tissue elements during the 3 years.…”

Effects of soil type and municipal solid waste compost as soil amendment on Cichorium spinosum (spiny chicory) growth

“…This is in agreement with other researchers who found yield increase in various crops (such as Mesembryanthemum edule, lettuce, triticale, winter squash fruits, etc.) with the addition of MSW compost (Fagnano et al, 2011;Lakhdar et al, 2011;Warman et al, 2009;Weber et al, 2014). Leaf water content and shoot to root ratios are very important growth parameters which concern the physiological functions of the plants.…”
