subsoil compaction, may occur naturally or a consequence of machinery traffic, causes reduction in crop yield. the aim of this work was to characterize the effects of subsoiling and irrigation on yield of corn. this study was conducted on the silty loam soils of miyandoab agricultural research station on the base of split plots design with 12 treatments and 4 replicates during the 1999 and 2000...

Deep tillage of compacted soils can improve potato (Solanum tuberosum L.) tuber yield and quality if no other production factors are limiting. We hypothesized that within-row subsoiling and N placement would affect tuber yields and availability of plant nutrients. Potato (cv. Russet Burbank) was grown after winter wheat (Triticum aestivum L.) in 1989 and after dry bean (Phaseolus vulgaris L.) i...

the split-block experimental design with three replications was used to study the effect of subsoiling in different distances from drain axison soil salinity,and wheat yield. the measurements included soil cone index, soil bulkdensity, infiltration rate and electrical conductivity of saturated extract. each treatment was composed of two factors. the main factors consisted of 3 different distanc...

Different soil management systems can change the sugarcane yield and quality parameters for sugar/ethanol production. The objective of this study was to evaluate effects subsoiling on inter-row ratoons after second harvest productivity technological quality. Productivity estimated in tonnes per hectare (TSH), were apparent sucrose percentage (Pol) total sugar recoverable (TRS). measured hectare...

Movement and persistence of 1,2-dibrotno-3-chloropropane (DBCP) in a Coastal Plain soil containing a sandy plow-pan were enhanced in each of 2 years by subsoiling, increased depth of application, and increased rate of application. DBCP was extracted from the soil with hexane and analyzed by gas chromatography. Subsoiling at a 35-cm depth gave the greatest increase in lateral movement and downwa...

BACKGROUND Long-term tillage has been shown to induce water stress episode during crop growth period due to low water retention capacity. It is unclear whether integrated water conservation tillage systems, such asspringdeepinter-row subsoiling with annual or biennial repetitions, can be developed to alleviate this issue while improve crop productivity. METHODS Experimentswere carried out in ...

soil. Planting of the crop over this low density slot is critical. These soils occur in the USA, primarily in the Using deep tillage to alleviate the adverse effects of deleterious soil Coastal Plains, and in other regions to a minor extent physical properties has been tried many times. Consistent economic returns have been reported for in-the-row subsoiling of loamy sand (Buol, 1973). and coar...

To provide a new way to increase water storage and retention of dryland wheat, a field study was conducted at Wenxi experimental site of Shanxi Agricultural University. The effect of subsoiling in fallow period on soil water storage, accumulation of proline, and formation of grain protein after anthesis were determined. Our results showed that subsoiling in fallow period could increase water st...

Abstract Incorporating trees into agricultural systems, including grasslands, increases the soil organic carbon sequestration and contributes to climate change mitigation. Site preparation for tree establishment is a common practice that can involve variety of techniques implements such as subsoiling. This study aimed evaluate long-term effects subsoiling on (SOC) concentrations stocks in Medit...
