Optimizing subsoiling depth to enhance soil water storage and annual crop water productivity in wheat-maize cropping system

Agricultural Water Management
Subsoiling effectively enhances crop water productivity (CWP) by optimizing soil structure. Nevertheless, the effects of different subsoiling depths on cross-seasonal soil water utilization and CWP remain unclear.

Strip rotary tillage with a two-year subsoiling interval enhances root growth and yield in wheat

Scientific Reports, 2019
Excessive tillage and soil compaction threaten the sustainable farmlands in the Huang-Huai-Hai Plains of China. Our study explores tillage practices to improve soil and root ecology and promote productivity in the winter wheat fields.

Specialized Committees of International Organizations an Important Source of Organizational Autonomy

Regulation &Governance, EarlyView.
ABSTRACT Assigning the preparation of decisions to specialized committees composed of member state representatives is a widespread response to the ‘governor's dilemma’, that is, the tension between competence and control, in international organizations (IOs). We theorize a causal mechanism referring to self‐selection and agenda‐setting effects and show

Effectiveness of liming and subsoiling to ameliorate a compacted arable clay subsoil

Acta Agriculturae Scandinavica. Section B, Soil and Plant Science
The effectiveness of mechanical subsoiling for alleviating subsoil compaction is controversially discussed, particularly due to the sensitivity of mechanically loosened soils towards re-compaction.

Consumo de combustível na operação de subsolagem realizada antes e depois de diferentes sistemas de preparo periódico do solo Fuel consumption in the subsoiling operation accomplished before and after different preparation systems of periodic soil tillage

Engenharia Agrícola, 2008
A subsolagem tem aumentado nos últimos anos de forma indiscriminada, faltando estudos que norteiem os melhores procedimentos para que novos problemas não sejam acrescentados devido a subsolagens inadequadas ou mesmo em solos onde a operação é ...

Influence of conservation tillage and soil water content on crop yield in dryland compacted alfisol of Central Chile [PDF]

, 2011
Chilean dryland areas of the Mediterranean climate region are characterized by highly degraded and compacted soils, which require the use of conservation tillage systems to mitigate water erosion as well as to improve soil water storage.

Initial Recovery of the Herbaceous Layer of a Temperate Deciduous Forest After 30 Years of Nitrogen Amendments: Implications for the Success of the Clean Air Act

Global Change Biology Communications, Volume 1, Issue 2, June 2026.
A hysteretic model predicts a time lag in the response of herbaceous layer variables (e.g., cover, diversity) to decreasing N deposition. To the contrary, virtually all such variables displayed a surprising sensitivity to decreased N. ABSTRACT Increases in nitrogen (N) emissions during the 20th century resulted in the atmospheric deposition of N ...
