Humans are currently confronted by many global challenges. These include achieving food
security for a rapidly expanding population, lowering the risk of climate change by reducing …

A simple method of estimating changes in biologically active soil carbon (C) could help
evaluate soil quality impacts of alternative management practices. Most reports of …

Soil scientists have developed the concept of soil quality (SQ) to describe the fitness of soils
to perform particular ecosystem functions (Karlen et al., 2001). SQ is usually defined as the …

Recognition of the importance of soil organic matter (SOM) in soil health and quality is a
major part of fostering a holistic, preventive approach to agricultural management. Students …

For many centuries manure application to the soil has been common practice. Organic
amendments and fertiliser applications can increase crop yields and soil organic matter …

Overuse of nitrogen (N) fertilizer to enhance agricultural production is threatening the
environment. The concentrations of reactive forms (eg, NOx, N 2 O, NO 3−, NH 3) of N have …

An appreciation of the dynamism of the links between soil resources and society provides a
platform for examining food security over the next 50 years. Interventions to reverse …

Due to inadequate data support, existing algorithms used to estimate soil hydraulic
conductivity, K, in (eco) hydrological models ignore the effects of key site factors such as …

The soil organic carbon (SOC) pool is the key indicator of soil health and quality which in
turn plays a vital role to soil sustainability. The continuous uses of unsustainable agricultural …

The long-term soil management effects on C and N stocks of soil physical fractions are still
poorly understood for South American subtropical soils. This study aimed (i) to evaluate the …
