石油和天然气钻井的增加导致了大量需要处理的水基“泥浆”（WBM）。WBM在农业用地上的土地应用是一种常见的处理技术，由于该材料富含总可溶性盐（TSS），因此提出了农艺和环境挑战。本研究的目的是确定WBM施用量对土壤盐分积累和淋溶的影响，以及施用时间和施用量对小麦（Triticum aestivumL.）产量的影响。在不同时间（10月、12月、1月、2月和3月）施用一次WBM，分别为0.66 × （4480 kg TSS ha - 1）和1.0 × （6720 kg TSS ha - 1）。分别于施药后0、30、90 d和8月28日（收获后）采集土壤样品，测定土壤电导率（EC）、pH和钠吸附比（SAR）。施水肥量对土壤ph值无影响。总体而言，施水肥量的增加在施水肥后0、30和90 d比未施水肥的土壤EC值增加。然而，这高度依赖于WBM应用和采样之间接收到的降水量。到8月，0 ~ 15 cm深度的土壤EC已降至4 mS cm−1以下。施用后土壤SAR在每个采样日期均呈上升趋势。施用量和施用量对小麦产量无显著影响。如果施用水肥少于6720 kg ha - 1，并根据降雨量和作物生长模式选择适当的时间，则可以最大限度地减少产量损失和盐积累。
Increased oil and gas drilling has resulted in large quantities of water-base “mud” (WBM) that requires disposal. Land application of WBM to agricultural land is a common disposal technique that presents agronomic and environmental challenges since the material is rich in total soluble salts (TSS). The objective of this study was to determine the impact of WBM application rate on salt accumulation and leaching in the soil, and the impact of application timing and rate on wheat (Triticum aestivumL.) production. A field study was conducted where WBM was applied once, at varying times (Oct., Dec., Jan., Feb., and March) at a 0.66 × (4480 kg TSS ha− 1) rate and 1.0 × (6720 kg TSS ha− 1). Soil samples were taken at 0, 30, and 90 days after application and on August 28th (post-harvest) for evaluating electrical conductivity (EC), pH, and sodium adsorption ratio (SAR). WBM rates had no effect on soil pH. In general, increasing WBM application rates increased soil EC beyond non-amended soils at 0, 30 and 90 days after application. However, this was highly dependent on the amount of precipitation received between WBM applications and sampling. By August, soil EC had decreased below 4 mS cm− 1at the 0–15 cm depth. However, soil SAR increased at every sampling date after application. WBM application date and rate had no significant effect on wheat (T. aestivumL.) yield. Yield loss and salt accumulation can be minimized if WBM is applied at less than 6720 kg ha− 1with proper timing relative to rainfall and crop growth patterns.
