“…De fato, alguns autores comentam em suas pesquisas que o gesso tem um papel fundamental na aplicação de PAM ao solo via sistema de irrigação, pois reduz a alta viscosidade desse polímero (YU et al, 2003;MAMEDOV et al, 2009). Entretanto, é importante ressaltar que, no caso dos hardsetting da Austrália, esses solos, além dos problemas da coesão, apresentam também o caráter salino, diferente dos coesos do Brasil, ácidos com pH, em água, normalmente entre 4,0 e 5,0 (GIAROLA & SILVA, 2002).…”

“…Under acidic conditions HCO 3 -ions are converted into gaseous CO 2 that escapes into the atmosphere. Acidic water may also help in (Yu et al, 2003). Zeolite, a geologic material with high cation exchange capacity (CEC), may enhance the ability of these materials to reduce the amount of Na + in CBNG waters (Boettinger and Ming, 2002).…”

Irrigation with coalbed natural gas (CBNG) co-produced water is a popular management option used by many gas companies operating in northwestern Powder River Basin (PRB), Wyoming. Depending upon local conditions and production rates, a CBNG well may be productive for 2 to 20 years, with an average lifespan of 7 years. At present there are over 20,000 CBNG wells permitted or drilled in the PRB region and it is estimated that another 50,000 to 100,000 new wells will be drilled in the future. The total CBNG water production in the PRB is expected to peak at about 47,000 ha-m in 2006 and the cumulative CBNG-water production during the period 2002-2017 is estimated to be 366,000 ha-m. CBNG water is dominated by sodium (Na + ) and bicarbonate (HCO 3 -) ions and the average discharge of a single CBNG well ranges from <1 to 100 liter per minute, with pH ranging from 6.8 to 9.0, electrical conductivities (EC) from 0.4 to 4 dS/m, Na adsorption ratio (SAR) from a low of 5 to an extreme high of 70 and total dissolved solids (TDS) concentrations from 270 to 2720 mg/L. Application of poorer quality CBNG water can have significant impacts on soil physical and chemical properties. Changes in soil chemistry due to land application of CBNG waters were investigated using lysimeters installed at depths of 15, 30, and 60 cm. Soil solutions collected during June to August 2004 from soil solution lysimeters were analyzed for EC and SAR. Soil solution chemistry data were compared with EC and SAR data from saturated paste extracts of CBNG irrigated soil samples collected at the same depth. Preliminary data indicate the build up of salts and Na in the upper horizons of irrigated fields. The EC values of lysimeter soil solution samples were greater than those of saturated paste. However, SAR of lysimeter soil solution and saturated paste extracts were comparable. The results of this study will be useful to understand potential changes in soil properties due to land application of CBNG waters and to develop possible mitigating criteria for reclaiming impacted PRB ecosystems.

“…Bjorneberg et al (2000) reported that PAM treatments were about as effective as a 30% mulch cover. Yu et al (2003) studied the rate of infiltration and soil loss for an Israeli silt loam and sandy clay with dry application of PAM. Distilled water was used to make artificial rain using laboratory sprinklers.…”

In recent years, high-molecular-weight anionic polyacrylamide (PAM) have been widely tested on a variety of soils, primarily in water erosion control. However, little information is available regarding the effectiveness of PAM on preventing soil loss from wind erosion. The research adopted room wind tunnel experiment, two kinds of soils were used which were from the agro-pastoral area of Inner Mongolia, the northwest of China, the clay content of soils were 22.0 and 13.7%, respectively. For these tests, all the treatments were performed under the condition of wind velocity of 14 m s −1 and a blown angle of 8.75%, according to the actual situation of experimented area. The study results indicated that using PAM on the soil surface could enhance the capability of avoiding the wind erosion, at the same time, the effect of controlling wind soil erosion with 4 g m −2 PAM was better than 2 g m −2 PAM's. Economically, the 2 g m −2 PAM used in soil surface can control wind erosion effectively in this region. The prophase PAM accumulated in soil could not improve the capability of avoiding the wind erosion, owing to the degradation of PAM in the soil and the continual tillage year after year. The texture of soil is a main factor influencing the capability of soil avoiding wind erosion. Soil with higher clay content has the higher capability of preventing soil from wind erosion than one with the opposite one under the together action of PAM and water.
