Diffusion and emission of smoke from agricultural burning in Hawaii

Agricultural burning has been common practice for many years in Hawaii. Cane fields are burnt before harvesting and the crowns of pineapple are cut-off during harvest, left in the field to dry and subsequently burned. While this practice has many advantages, it produces air pollution levels which at least one study finds affect public health. In 1974 open burns of cane and pineapple were simulated in a burn tower where samples were burned while monitoring weight loss and smoke density. From these measurements emission values were calculated. However, because questions were raised as to whether the vigorous field fires can be simulated in a burn tower, a field survey was undertaken and a diffusion model, basically a limited Gaussian line source model, was developed and run using the data collected during the burns. The calculated emission rate for particulates is orders of magnitudes larger than the burn tower rate. This is attributed to dust drawn into the fire. When emission values from a survey of the open burn literature and from the present study were plotted against wind speed, low intensity fires such as grass, straw and pineapple residue fires showed decreased emissions with increasing wind speed while cane fires showed increased emission. This suggests that emission characteristics are different for low and high intensity fires. For low intensity fires increased air flow acts mainly to increase the combustion efficiency producing less particulates.

“…Thus, many producers in the midsouthern and southeastern United States choose to burn wheat residue soon after harvesting to facilitate timely planting of soybean (Sanford, 1982). However, burning has been reported to decrease soil C, N, aggregate stability, water infiltration (Wuest et al, 2005;Murphy et al, 2006), and extractable soil P, S, Ca, and Mg compared with leaving residue intact on the soil surface (Murphy et al, 2006) 780 AMURI AND BRYE SOIL SCIENCE while increasing gaseous emissions of N, C, and S caused by high temperatures during combustion, which favor volatilization of the gaseous forms of these elements (Boubel et al, 1969;Caldwell et al, 2002;Murphy et al, 2006). Although surface residues have been reported to reduce machine-induced compaction in forest soils (Ess et al, 1998), retaining crop residues in agricultural fields has produced varied results with regard to soil compaction (Guerif, 1979;Ess et al, 1998).…”

Improving long-term agricultural sustainability requires appropriate soil and residue management practices. Soil cone index (CI), which relates to the resistance to penetration of a cone of specific dimensions, is an important physical property relating to soil and crop productivity, particularly in intensive cropping systems. A study was initiated in 2001 to evaluate the effect of alternative residue management practices on soil penetration resistance in a wheat (Triticum aestivum L.)-soybean (Glycine max [L.] Merr.) double-cropped system in the Mississippi River Delta region of eastern Arkansas. Residue management treatments consisted of tillage (conventional tillage and no-tillage [NT]), residue burning (burn and no burn), and residue level (low and high, achieved by differential N fertilization). Soil CI, as measured using a hand-pushed penetrometer, was determined at 0.05-m intervals to a depth of 0.4 m in 2003, after one, and in 2006, after four complete cropping cycles. The whole-field CI increased with depth in both years. Tillage, burning, and residue level generally did not affect CI in the top 0.20-m in either year. In both years, soil CI was consistently lower under burning than nonburning at all depths below 0.20 m. Compared with after only 1 year, 4 years of NT soybean resulted in a 35% increase in CI at the 0.05-m depth. Soil CI was reduced at the 0.4-m depth under NT and nonburning but increased somewhat under conventional tillage and nonburning after 4 years. Being aware of the potential effects of alternative residue management on soil properties and root growth in relation to soil penetration resistance will be necessary for sustainable soil management practices.

“…4 - 5 It is also possible, however, that the many large particles in the rather dense cane smoke could have caused some under recording of light scatter by the nephelometer. A large number of field investigations would obviously be necessary to establish the magnitude of the emission factor for sugar cane fires using this approach.…”
