Boreal lands have long been considered unsuitable for agriculture. Climate change projections support a shift towards increased agricultural production in boreal ecosystems via land use conversion. Depending on the conversion protocol, new plough layer may variably reflect properties of different soil depths. This study assessed how adding mineral or organic fertilizer sources to distinct layer...

Yield reduction in okra production is mostly associated with cultivation of marginal lands or continuous land cultivation. Hence, the need for sustainable approach to resuscitating soil fertility through Tithonia diversifolia manure application may alter microbial population. Two depths [Topsoil (0-15 cm) and Subsoil (15-30 cm)], three levels applications (control, half recommended at 120 kg N/...

The objectives of this review are to summarize existing information on the occurrence of pesticides In groundwater and processes resulting in their detection; to identify existing technologies, and to describe missing information needed to make assessments arid predictions. Validated data on the occurrence of pesticides in groundwater are still limited. Pesticides can reach groundwater followin...

Based on a series of shaking table model tests, it was found that the eŠects of 1) subsoil and backˆll deformation, 2) failure plane formation in backˆll, and 3) pullout resistance mobilized by the reinforcements on the seismic behaviors of the geosynthetic reinforced soil retaining walls (GRS walls) were signiˆcant. These eŠects cannot be taken into account in the conventional pseudo-static ba...

Earthworms being the most efficient soil organism to improve soil fertility by burrowing deeply into subsoil surfaces and then releasing it out in the form of nutrient enriched cast (Lavelle, 2011). As they are abundant in number and highly productive species, so they are keystone species in the food web of soil environment (Thakuria et al., 2010). Earthworm burrows and drilosphere act as micro...

Acidic (pH 4.1) and high Cd, Pb, and Zn mine tailings (mean +/- SD: 17 +/- 0.4, 3800 +/- 100, and 3500 +/- 100 mg kg(-1), respectively) from an alluvial tailings deposit in Leadville, Colorado were amended with municipal biosolids (BS) (224 Mg ha(-1)) and different types of lime (calcium carbonate equivalent of 224 Mg ha(-1) CaCO3) in a greenhouse column study to test the ability of the amendme...
