PLOUGHING DEPTH STABILITY WITH FRONT PLOUGH WITHOUT SUPPORT WHEEL

Then aggregating a front plow, an important aspect is ensuring the stability of the plowing depth. This issue becomes especially relevant if this implement does not have a support wheel. In view of this, the purpose of this article is to find out the influence of the operation of a front plow without a support wheel on the stability of the depth of ...

Effect of Tillage Implement Type and Depth of Ploughing on Field Performance Parameters in Vertisol Clay Soil of Gezira Scheme (Sudan)

, 2021
Abstract This study was conducted during 2017 in Gezira scheme which is characterized by heavy vertisol clay soil. The objective of the study was to evaluate the field performance (effective field capacity "EFC", field efficiency "FE", draft, fuel consumption and drawbar power) of three tillage implements (Chisel Plough "CP", Moldboard Plough "MP" and ...

Impact of Irrigation Scheduling on Corn Yield and Water Balance in Sandy Soils of Central Minnesota Using the EPIC Model.

Irrigation and Drainage, EarlyView.
ABSTRACT Efficient irrigation scheduling is critical in sandy soils to achieve optimum yield and maximum net benefit with minimum environmental concerns. The Environmental Policy Integrated Climate (EPIC) model was used to study the impacts of autoirrigation of corn on crop yield and soil water balance during 2019–2021 at −300 and −450 kPa for loamy ...

Field Studies on the Influence of High‐Voltage Direct Transmission Underground Cables on Soils Along the SuedLink Route in Southwest Germany

Journal of Plant Nutrition and Soil Science, EarlyView.
During regular operation of the SuedLink at a load ≤75 %, the average increase in temperature in the plowing horizon is expected to be less than 1.6°C in the soils along the route in Southwest Germany. ABSTRACT Background The SuedLink was planned as a high‐voltage direct‐current underground cable route. The construction itself is a massive intervention

Fatal germination in barnyardgrass (Echinochloa crus-galli)

Plant Protection Science, 2013
Seeds of weeds buried by tillage may germinate at depths from which seedlings cannot establish. In barnyardgrass (Echinochloa crus-galli) we investigated how fatal germination was influenced by the depth and time of seed burial.

Sewage Sludge and Cashew Bagasse Biochars Promote Changes in Selected Physical Attributes Related to the Structure of Degraded Dryland Soil

Journal of Plant Nutrition and Soil Science, EarlyView.
This study evaluated biochars from co‐pyrolysis of sewage sludge and cashew residues on physical quality of a degraded loamy sand soil. SPB applied at 20 Mg ha−1 reduced bulk density by 7.74%, whereas most porosity attributes were driven by soil reconsolidation rather than biochar. Aggregate stability varied with biochar type, with SPB promoting larger

Influence of Agrotechnical Practices and Sowing Time in Various Weather on Soybean Yield

Acta Technologica Agriculturae, 2023
For seed germination and the formation of a good soybean crop, significant reserves of soil moisture are required, which depends on the autumn-winter soil preparation, weather conditions and planting dates.
