Abstract Since the late 1980s, various experiments have been conducted in polymetallic nodule fields of Pacific Ocean to assess potential environmental impacts future mining, specifically two areas: Peru Basin and Clarion-Clipperton Fracture Zone (CCZ). Two expeditions, SO242/2 2015 (Peru Basin) SO268/1 + 2 2019 (CCZ), deployed a towed camera system collect imagery from both areas. These expedi...

The creeping perennial weed species Cirsium arvense (L.) Scop. occurs in patches. Expanding roots allow these patches to increase their covered area. This characteristic has rarely been addressed when investigating the effects of control options arable fields. We designed a three-year field experiment (2019–2021) north-eastern Germany, accounting for existing patch patterns. experimental setup ...

Soil conventional tillage has been associated with deterioration of its characteristics, while organic farming promoted as an approach to conserve a favorable soil environment. With the interest in nominating strategies without ploughing for maintaining long-term quality and subsequently increasing yields, this study set identify if how conservation practices management (OM) do improve physical...

The regional agroecological conditions, specific to the Transylvanian Plain, are favorable soybean crops, but microclimate changes related global warming have imposed need for agrotechnical adaptive measures in order maintain level of yield. In this study, we consider effect two soil tillage systems, seeding rate, as well fertilizer dosage and time application on yield quality crops. A multifac...

the erosion in dryland caused decrease in yield and soil quality, especially in slope land with conventional tillage. to investigate effect of tillage and planting methods in slope land on erosion and yield of dryland wheat, an experiment was conducted in 2007 at kermanshah province. the statistical design for this research was strip split plots in rcb (randomized complete blocks) with three re...

Continued population growth in densely populated parts of Sub-Saharan Africa makes it harder for youth to choose agriculture as main source income. We investigate whether near landless can access rented land a used data collected 2016 (from 1138 youths 119 business groups) and 2019 2427 246 groups), five districts Tigray region Ethiopia. find that 42% the had 47% 2019. The average area was 0.66...

Best nitrogen management practices are the pre-requisite to warrant high maize yield. Thus, experiments were conducted to study the “effect of tillage and split application of nitrogen on hybrid maize” under semi-arid conditions of Pakistan, during fall 2008 and 2009. The experiments were laid out in randomized complete block design with split-plot arrangement, replicated three times in a net p...

Although agricultural land management is known to affect near-surface soil physical quality (SPQ), the characteristics of these affects are poorly understood, and diagnostic SPQ indicators are not well-developed. The objective of this study was to measure a suite of potential SPQ indicators using intact soil cores and grab samples collected from the 0–10 cm depth of a clay loam soil with the tr...

The objective of this study was to investigate the effect soil tillage and crop type on respiration (Rs) in a typical Central European agricultural site characterized by rotation. weekly Rs supporting environmental variables were measured under different types (including winter summer crops) for 5 consecutive years mouldboard ploughing (MP) no-tillage (NT) treatments. long-term mean 0.093 mg CO...

For decades, conservation tillage has been promoted as a measure to increase carbon stocks in arable soils. Since organic farming improves soil quality and storage, reduced under conditions may further enhance this potential. Therefore, we assessed (SOC) of compared with mouldboard ploughing nine field trials France, Germany, the Netherlands, Switzerland same sampling analytical protocol. We sa...
