Effect of inorganic fertilisers and organic amendments on soil aggregation and biochemical characteristics in a weathered tropical soil

Soil & Tillage Research, 2019
Highly weathered laterite soils are a characteristic feature of humid tropics with undulating topography and high rainfall. The crop of cashew (Anacardium occidentale L.) has been cultivated in such landscapes, mainly to prevent further degradation due ...

Glomalin-related soil protein affects soil aggregation and recovery of soil nutrient following natural revegetation on the Loess Plateau

, 2020
The glomalin-related soil protein (GRSP) is an important fraction of soil organic carbon (SOC) and soil nitrogen (N), and is important for stabilization of SOC and soil aggregates.

Soil aggregates as mass fractals

Australian Journal of Soil Research, 1995
Soil aggregates have a fractal mass. That is, they are porous and, as they are studied in greater detail, more pores may be observed. Mass fractals have scale-dependent bulk density. Larger objects, or soil aggregates, have a smaller bulk density. Bulk density in soil studies is sometimes assumed to be constant.

Dynamics of Soil Aggregation

1966
Publisher Summary This chapter discusses the factors and mechanisms governing the formation and destruction of water-stable soil aggregates. The formation and degradation of water-stable aggregates comprise a complex interrelationship of physical, biological, and chemical reactions.

Dynamics of soil aggregation and organic carbon fractions over 23 years of no-till management

, 2020
Evaluation of aggregate formation in no-till farming systems and the effects on soil organic matter can provide relevant insights into soil carbon storage, nutrient cycling, and soil susceptibility to erosion.

Aggregation in swelling clay soils

Australian Journal of Soil Research, 1973
Dry sieving, wet sieving, and aggregate bulk density measurements were used to study the mechanisms of dry aggregate formation in three swelling clay soils. These experiments showed that, for a given soil, a single probability function can be used for all dry aggregate fractions to predict their water stability and the distribution of water stable ...

Diversification of maize-wheat cropping system with legumes and integrated nutrient management increases soil aggregation and carbon sequestration

Geoderma, 2019
Retention of carbon in arable soils has been recommended as an important mechanism to mitigate the climate change and sustainability of the agro-ecosystems. We reasoned that legume-inclusive crop rotations and integrated nutrient management would promote

Dominant tree species and earthworms affect soil aggregation and carbon content along a soil degradation gradient in an agricultural landscape

, 2020
Soil organic matter (SOM) is considered an important determinant of soil fertility in tropical agroecosystems. While numerous studies have shown the value of agroforestry in increasing soil nutrients and improving crop yield, few have addressed the ...

Soil aggregates and water retention

2004
Publisher Summary This chapter explains the way aggregate-size distributions affect soil water retention from saturation to the wilting point. It uses the van Genuchten approximation of gravimetric water retention data and describes the effects of both aggregate-size distributions and particle-size distributions (PSDs) on parameters of the van ...
