Analytical modelling of soil porosity and bulk density across the soil organic matter and land-use continuum [PDF]

Scientific Reports, 2022
The thin layer of soil at the earth’s surface supports life, storing water and nutrients for plant uptake. These processes occur in the soil pore space, often half the soil volume, but our understanding of how this volume responds to environmental change

Effects of Biochar and PGPR Application on the Physicochemical Properties and Humus Components of Soil Used for Planting Fruit Mulberry Seedlings Under Salt Stress [PDF]

Biology
Biochar can act as a carrier and a soil carbon source for rapid colonization by plant growth-promoting rhizobacteria (PGPR). However, the effects of a combined application of biochar and PGPR on soil physicochemical properties, humus components, and ...

Empirical Model for Estimation of Soil Permeability Based on Soil Texture and Porosity

Jurnal Teknik Pertanian Lampung, 2023
Soil permeability is the ability of the soil to pass water or air. Soil permeability is affected by texture, structure, and soil porosity. This study aims to develop a mathematical model to predict the value of soil permeability as a function of the ...

Soil Compaction Effects on Root-Zone Hydrology and Vegetation in Boreal Forest Clearcuts [PDF]

, 2019
Soil compaction is a common consequence of forestry traffic traversing unprotected, moist soils; it decreases porosity and affects hydraulic conductivity even in coarse-textured soils. The aim here was to study root-zone hydrology and vegetation in three
