Secondary succession on an early abandoned field: vegetation composition and production of biomass
During 1996-2000 the secondary succession on a field left fallow was investigated. The experimental area was divided into a ploughed and an unploughed part.

Weeds and crop yields under conservation tillage in organic farming. [PDF]
Conservation tillage in conventional agriculture tends to make the cropping systems more dependent on herbicides. Organic farming principles could solve this problem. However, direct drilling under a cover crop in organic farming remains difficult.

Effects of Tillage Methods and Nitrogen Fertilizer on Soil Properties and Performance of Yellow Oleander in Southern Nigeria [PDF]
A study was conducted at the Research Farms of Biofuel Alternate and Renewable Energy Ltd, Edidi, Kwara State, Nigeria. Zero tillage, ploughing once and ploughing + harrowing and three rates of nitrogen fertilizer (0, 30, 60 Kg ha-1 Urea) were evaluated ...

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

Field trials on grain maize cultivation technologies in 2004, 2005 and 2006
The paper presents the results of field studies that assess the influence of various technologies of maize-for-grain cropstand establishment on not only its yield, but also on labour and fuel consumption, and individual cost components. The field studies

Effects of burying and removing dead leaves from the ground on the development of scab epidemics in an apple organic orchard. [PDF]
Ascospores produced on scabbed leaves in the leaf litter constitute the primary inoculum causing scab infections in apple orchards during the year.

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

Some environmental aspects of grassland cultivation; the effects of ploughing depth, grassland age, and nitrogen demand of subsequent crops [PDF]
The Netherlands has submitted a derogation under the Nitrate Directives to the European Union (EU) in 2000. In the final opinion by a group of experts about the Dutch derogation, recommendations on ploughing of grasslands were included dealing with i ...

Nitrogen turnover and leaching in cropping systems with ryegrass catch crops [PDF]
This thesis deals with perennial ryegrass (Lolium perenne L.) catch crops and their short- and long-term effects on nitrogen leaching and nitrogen turnover in soils. Results are presented from three field experiments on a sandy soil in south-west Sweden,

ABSTRACT Background: Soil quality can be measured through soil quality indicators that reflect soil processes. Aim: The aim of this study was to (1) identify a limited set of soil quality indicators that are most sensitive to agricultural soil management and that are widely applicable regardless of pedo‐climatic conditions, and (2) link common ...
