Boron availability and fertilizer response of maize in soils from sub‐Saharan Africa

Journal of Plant Nutrition and Soil Science, EarlyView.
Abstract Background and aims Low boron (B) availability is associated with strongly weathered, coarse‐textured, and low organic matter soils, widespread in sub‐Saharan Africa (SSA). It is unknown to what extent B fertilization can increase maize yields in SSA.

Model averaging for mapping topsoil organic carbon in France

, 2020
The soil organic carbon (SOC) pool is the largest terrestrial carbon (C) pool and is two to three times larger than the C stored in vegetation and the atmosphere. SOC is a crucial component within the C cycle, and an accurate baseline of SOC is required,

Perennial Legumes Pueraria phaseoloides and Leucaena leucocephala Exhibit High Potential for Fertility Restoration of Degraded Mined Soils in Ghana

Journal of Plant Nutrition and Soil Science, EarlyView.
Revegetating the subsoil layer of abandoned gold mined sites with the perennial legumes Leucaena Leucocephala, Pueraria phaseoloides and Gliricidia sepium without any soil amendments increases the content of soil organic carbon and important macro‐nutrients, which are crucial for restoring soil health and productivity. These improvements in soil health

Contrasting Biogeographic Patterns of Bacterial and Archaeal Diversity in the Top- and Subsoils of Temperate Grasslands

mSystems, 2019
Biogeographic patterns and drivers of soil microbial diversity have been extensively studied in the past few decades. However, most research has focused on the topsoil, while the subsoil is assumed to have microbial diversity patterns similar to those of

Organo-Mineral Interactions Are More Important for Organic Matter Retention in Subsoil Than Topsoil

Soil Systems, 2020
Decomposing crop residues contribute to soil organic matter (SOM) accrual; however, the factors driving the fate of carbon (C) and nitrogen (N) in soil fractions are still largely unknown, especially the influence of soil mineralogy and autochthonous ...

Technical Guidance Sheet (TGS) on normal levels of contaminants in English soils : copper (Cu) : technical guidance sheet supplementary information TGS03s, July 2012 [PDF]

, 2012
Both the NSI (XRFS) and G-BASE data sets are derived from a soil sample that has been aggregated (composited) from a number of subsamples collected over the area of a site, rather than a single point sample.

Enhanced soil quality with reduced tillage and solid manures in organic farming - a synthesis of 15 years [PDF]

, 2020
Demands upon the sustainability of farming are increasing in step with climate change and diversity loss. Organic farming offers a viable approach. To further improve organic management, three strategies with potential to enhance soil quality are being ...

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

Investigating the Influence of Biochar Amendment on the Physicochemical Properties of Podzolic Soil

Agriculture, 2020
Research into biochar, as an amendment to soil, has increased over the last decade. However, there is still much to understand regarding the effects of biochar type and rates on the physicochemical properties of different soil types.
