Effects of no-tillage and subsoil loosening on soil physical properties and crop performance : a thesis presented in partial fulfilment of the requirements for the degree of Master of Applied Science in Soil Science at Massey University [PDF]
, 1998 Much of New Zealand's lowland agriculture integrates animal and crop production on poorly drained, easily compacted soils. Over the years, conventional cultivation has given rise to degraded soil structure on many farms.

No-Tillage impacts on soil hydraulic properties compared with conventional tillage
, 2012 Soil hydraulic properties are very important in precision irrigation, water and solute transport and irrigation scheduling. Tillage can change near surface soil hydraulic properties. In this study Beerkan methodwas used to better understand tillage and no-tillage impacts on transmission properties of topsoil.

International Journal of Climatology, EarlyView.Climate models generally reproduce the WAWJ and August peak but simulate its onset prematurely and too strongly relative to ERA5. CMIP6 simulations struggle to reproduce the jet–precipitation relationship in the Sahel and underrepresent associated moisture transports.

Multi‐Country‐Multi‐City Characterisation of Heat Stress and Exposure in Africa
International Journal of Climatology, EarlyView.This study provides the first continent‐wide, grid‐specific assessment of heat stress trends in Africa, revealing a sharp rise in multi‐scale extreme heat episodes and shifting population exposure. Findings highlight urgent implications for urban planning and climate adaptation.

Threats to soil quality in Denmark - A review of existing knowledge in the context of the EU Soil Thematic Strategy [PDF]
, 2009 The EU Commission is preparing a proposal for a Soil Framework Directive with the purpose of protecting the soil resources in Europe. The proposal identifies six major threats to the sustained quality of soils in Europe. This report addresses the threats

Borax Promotes Fertility of Brassica napus Better Than Other Boron Species at Suboptimal Supply
Journal of Plant Nutrition and Soil Science, EarlyView.ABSTRACT Background Continuous and sufficient boron (B) supply is essential for achieving maximum yield in Brassica napus. Increasing incidences of environmental water limitation are linked to reduced plant B availability and increased B deficiencies.

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
