Long-term tillage and residue management effect on soil compaction and nitrate leaching in a Typic Haploxerert soil
A field experiment was conducted to compare the effects of long-term tillage and cropresidue management on some physical properties and nitrate leaching of a Typic Haploxerertsoil under winter wheat (Triticum vulgare L.)-soybean (Glycine max L.) double-croppingsystem. The tillage systems consisted of conventional tillage with stubble (CT1), conventionaltillage with stubbles burned (CT2), heavy ...
متن کاملManures behave similar to superphosphate in phosphorus accumulation in long-term field soils
Repeated application of manures to agricultural soils could cause the accumulation of phosphorus (P) in soils. However, it is unclear if manure P can behave similar to P in soluble fertilizers in accumulation Olsen-P (0.5 mol L-1 NaHCO3 at pH 8.5) in soils. A long-term wheat-maize rotation experiment was conducted to investigate the effects of repeated application of manures on P accumulation i...
متن کاملاثر مدیریت مرتع بر توزیع اندازه و پایداری خاکدانهها به روش الک تر و خشک در مراتع سبزکوه و بروجن استان چهارمحال و بختیاری
Free and uncontrolled pasture grazing by animals may decrease soil aggregate stability through reductions in plant cover and subsequent soil organic C, and trampling. This could expose the soil surface layer to degradation and erosion. The objective of this study was to determine the influence of pasture management (free grazing, controlled grazing and long-term non-grazing regimes) on aggregat...
متن کاملImpact of Wastewater Irrigation on Soil Mechanical Properties in the Green Space of Mobarakeh Steel Complex
Long-term use of treated wastewaters for irrigation adds compounds and/or ions to soils which might alter the soil physical, hydraulic and mechanical properties. Soil mechanical properties are closely linked with the plant growth. This study was conducted to investigate the effect of short-, mid- and long-term applications of the treated wastewater of Mobarake Steel Company in Isfahan on the so...
متن کاملShort- vs. Long-Term Effects of Reactive Incidental Focus on Form in Free Discussion EFL Classes
This study investigated the effectiveness of reactive incidental focus on form (FonF) for each learner with regard to different linguistic categories in meaning-oriented EFL classes. To this end, 30 hr of meaningful interactions of upper-intermediate EFL learners were audio-recorded in 2 free discussion classes. Instances of reactive incidental focus-on-form episodes (FFEs), where teachers offe...
