ABSTRACT Full inversion tillage (FIT) at pasture renewal is a management option aiming to increase carbon stocks in long‐term pasture, to achieve carbon neutrality. This study investigated the effects of FIT on carbon and nutrient distribution in the soil profile (0–7.5, 7.5–15, 15–22.5 and 22.5–30 cm depths) as well as nutrient uptake, and subsequent ...

Chemical nature of residual phosphorus in Andisols
International audienceSequential fractionation has been widely used to study the nature and dynamics of soil P. Residual P - the recalcitrant P fraction remaining after sequential extraction with alkali and acid reagents - often constitutes the majority ...

Metal complexation of humus and horizon differentiation in Andisols and Spodosols [PDF]
application/pdfFrom tephra, not only Andisols, but Spodosols can also be formed depending on changes in the soil formation factors. In Andisols, the in situ accumulation of humus in the A horizon and that of the active Al and Fe in the A and Bw horizons ...

ABSTRACT The safe application of farm dairy effluent (FDE) to land has proven to be a challenge for dairy farmers and regulatory authorities throughout New Zealand. Poorly performing FDE systems can have deleterious effects on water quality because contaminants such as phosphorus, nitrogen and faecal microbes enter receiving waters with minimal ...

Path Analysis of Phosphorus Retention Capacity in Allophanic and Non-allophanic Andisols
Andisols derived from volcanic ash minerals are characterized by a high P retention capacity (PRC). The PRC of soil is often correlated with various soil properties, and a simple correlation analysis alone may not necessarily explain the direct cause and

Aggregate and soil organic carbon dynamics in South Chilean Andisols [PDF]
Extreme sensitivity of soil organic carbon (SOC) to climate and land use change warrants further research in different terrestrial ecosystems. The aim of this study was to investigate the link between aggregate and SOC dynamics in a chronosequence of ...

Fertilizer effects on phosphorus fractions and organic matter in Andisols [PDF]
Andisols are characterized by a high phosphorus (P) fixation capacity, which is a limiting factor for plant production. Continuous application of P fertilizer may result in an accumulation of P associated with soil organic matter (SOM), which further ...
