Soil and Tillage Research, 2015 The effect of ploughing depth and mechanical soil loading on the performance of pea sole crops, oat sole crops and pea–oat intercrops was investigated in field experiments under organic farming conditions at two sites in Germany in 2009 and 2010. The two ploughing depths were short-term shallow ploughing to a soil depth of 7–10 cm and deep ploughing to

Long-term experiments with different depths of mouldboard ploughing in Sweden
Soil and Tillage Research, 1998Abstract With the main objective to produce a basis for advice to farmers concerning optimal ploughing depth under various conditions, a series of field experiments were initiated throughout Sweden. At 19 sites on various soils (clay content 72–521 g kg −1 , organic matter content 21–89 g kg −1 ) mouldboard ploughing to about 15, 22 and 28 cm depth ...

Abstract. Increasing the ploughing depth and ploughing in grassland has been common in Germany during the past 20 years. Incubation studies were conducted with topsoils from luvisols and gleysols at different times after change of management in order to assess its influence on nitrogen mineralization and its ...

Abstract The relative effects of using light (2–3 Mg) versus heavier (5–7 Mg) tractors, shallow (15 cm) versus deeper (25 cm) ploughing and on-land versus in-furrow wheel placement during ploughing were investigated from 2003 to 2006 in organic rotations (wheat or barley, green manure, oats with peas) and conventionally fertilized barley. Trials were

This paper examines the effect of ploughing depths (A — 60 cm, B — 45 cm and C — 30 cm) on the growth and yield ofHeracleum candicans Wall (Apiaceae), a threatened medicinal herb of the Himalayan region. This less-explored plant is being suggested as a potential crop for the mountain agriculture.

To ensure optimum conditions for organic cereal growing, it is important to minimize both compaction and soil inversion depth. The relative effects of using light versus heavier tractors, shallow versus deeper ploughing and on-land versus in-furrow wheel placement during ploughing were investigated in three-year organic rotations dominated by cereals ...

Soil and Tillage Research, 1994
Abstract The effect of ploughing depths, seedbed preparation and nitrogen fertilisation on a loam soil (fluvaquentic humaquept) were investigated in a factorial field experiment on a loam soil at As in southeastern Norway. The experiment was established in the autumn of 1939, reorganised in 1962 and was completed in the autumn of 1990.

Soil management by shallow mouldboard ploughing in The Netherlands
Soil and Tillage Research, 2002 The structure of the soil in the arable layer is controlled by tillage, soil biota activities and weathering, whereas the structure below this layer is mainly the result of the activities of soil biota.

‘The depth of the plough’: white settler tautologies and pioneer lies
Settler Colonial Studies, 2019This article introduces the concept of the white settler tautology – something that seems true by the very nature of its repetition and logical irrefutability in white settler histories, stories, a...
