Title. Reclamation techniques for soils treated with non-selective residual herbicides (soil sterilants) Related Titles. Series: Report (Alberta. Reclamation Research Technical Advisory Committee) ; . Reclamation techniques for soils treated with non-selective residual herbicides (soil sterilants) / By M. M. Cotton, M. P. (Mahendra P.) Sharma, Alberta. Alberta Environmental Protection., Alberta. Land Conservation and Reclamation Council. and Alberta. Reclamation Research Author: M. M. Cotton, M. P. Sharma, Alberta. By crops which remove bases from the soil, eg: sugar beet. Reclamation of acidic soil: There are some methods by which the acidity of soil can be neutralized and the soil can be made pH balanced: By adding liming material to the soil, eg: calcium hydroxide. By use of basic fertilizers in the soil, such as basic slag, sodium nitrate etc. In Saline–sodic soils reclamation involves the addition of good-quality water to remove excess soluble salts and the use of a Ca 2+ source (CaSO 4 2H 2 O or CaCl 2) to exchange Na + from the soil as a soluble salt, Na 2 SO 4. In Saline–sodic soils a saltwater-dilution method is usually effective in reclamation.
Modern soil reclamation techniques need to be tested more frequently in alkaline soils as well, because these soils are also under threat of Cd toxicity, as seen in Pakistan. Interdisciplinary work needs to be done involving soil scientists, plant breeders for technical research on Cd decontamination of soils, and Cd-resistant plant development. Problematic Soil sterilant are non-selective residual herbicides that render the treated soil unfit for plant growth for relatively long periods of time. Sterilant, were commonly used in Alberta from the s to late s for non-selective vegetation control on oil . Herbicide use while being of a great benefit in controlling weeds in agricultural systems can also pose a threat to environmental quality due to off-target and off-site impacts. The increasing concern about risks associated with agricultural chemicals and specifically their impact on surface and groundwater quality is a national and international concern. In Kentucky, herbicide off-site. Herbicides for Cogongrass • Imazapyr (Arsenal or Habitat) Soil activity & residual, selective at lower rates • Glyphosate (Round-up or Rodeo) No residual, non-selective • Fluazifop-butyl (Fusilade) Selective grass killer (broadleaf competition) • Sulfometuron-methyl (Oust) tank mix • Aminocyclopyrachlor (Method) new.
Amitrole is a more effective, non-selective systemic herbicide used to control more difficult weeds like docks, bamboo and couch. Dicamba controls tougher annual and perennial weeds, notably bracken and nettles. Simazine is a residual herbicide, staying in the soil and effective for up to six months. It is used as a pre-emergent treatment. Assessment, Restoration and Reclamation of Mining Influenced Soils covers processes operating in the environment as a result of mining activity, including the whole spectra of negative effects of anthropopressure and the environment, from changes in soil chemistry, changes in soil physical properties, geomechanical disturbances, and mine water. Soil Reclamation is the process of reclaiming the soil’s quality like lost fertility, minerals, nutrients and moisture to make it fit for intensive use again. The reclamation of soil, its nutrients and fertility are done with an objective to increase further land use and enhance agricultural activities like cropping and irrigation. Land reclamation - Land reclamation - Reclamation of salt-affected soils: In the arid regions of the world, and along coastal areas subject to periodic inundation by sea water, soils may have such a high content of soluble salts that production of economic plants is not possible. The salts found in soils are generally the chlorides, carbonates, bicarbonates, and sulfates of sodium, with lesser.
