A COMPARISON OF RUNOFF QUALITY EFFECTS OF ORGANIC AND INORGANIC FERTILIZERS APPLIED TO FESCUEGRASS PLOTS1

ABSTRACT: Application of fertilizer can degrade quality of runoff, particularly during the first post-application, runoff-producing storm. This experiment assessed and compared runoff quality impacts of organic and inorganic fertilizer application for a single simulated storm occurring seven days following application. The organic fertilizers used were poultry (Gallus gallus domesticus) litter, poultry manure, and swine (Sus scrofa domesticus) manure. All fertilizers were applied at an application rate of 217.6 kg N/ha. Simulated rainfall was applied at 50 mm/h for an average duration of 0.8 h. Runoff samples were collected, composited, and analyzed for nitrate N (NO₃-N), ammonia N (NH₃-N), total Kjeldahl N (TKN), ortho-P (PO₄-P), total P (TP), chemical oxygen demand (COD), total suspended solids (TSS), fecal coliforms (FC), and fecal streptococci (FS). Application of the fertilizers did not alter the hydrologic characteristics of the receiving plots relative to the control plots. Concentrations of fertilizer constituents were almost always greater from treated than from control plots and were usually much greater. Flow-weighted mean concentrations of NH₃-N, PO₄-P, and TP were highest for the inorganic fertilizer treatment (42.0, 26.6, and 27.9 mg/L, respectively). Runoff COD and TSS concentrations were greatest for the poultry litter treatment. Concentrations of FC and FS were greater for fertilized than for control plots with no differences among fertilized plots, but FC concentrations for all treatments were in excess of Arkansas' primary and secondary contact standards. Mass losses of fertilizer constituents were low (≤ 3 kg/ha) and were small proportions (≤ 3 percent) of amounts applied.     

腾晖煤业采空区顶板超长定向钻孔模拟与应用研究

基于采动裂隙椭抛带理论提出顶板超长定向钻孔治理技术,通过理论推导、数值模拟、现场应用相结合的方法对腾晖煤业2-100放顶煤工作面顶板超长定向钻孔的合理距离及合理层位进行研究。研究结果表明:1~5号顶板超长定向钻孔内错回风巷的合理距离为20~40 m;钻孔的合理终孔层位依次为60,60,60,61和63 m。顶板初次垮落后,顶板超长定向钻孔开始发挥作用,单孔的瓦斯抽采纯量随着工作面推进开始呈周期性变化,当顶板岩层发生周期性垮落时,钻孔瓦斯抽采纯量开始急剧升高;抽采纯量达到的最大值分别为13.88 ,13.92 ,13.96,14.24 和14.32 m3/min;顶板超长定向钻孔抽采期间,上隅角瓦斯浓度与回风流瓦斯浓度呈周期性变化趋势,上隅角瓦斯浓度为0.32%~0.8%,整个过程中上隅角瓦斯浓度均在可控范围内。顶板超长定向钻孔治理技术可有效解决放顶煤工作面采空区的瓦斯治理难题。
