Organic matter and nutrient supply
Biotic and abiotic factors determine nutrient availability from decomposing soil organic matter.
Organic matter biomass calculator
Calculate the amount of plant biomass required to change organic carbon percentage
Soil predation and pore space
All organisms in soil occupy the pore space surrounded by mineral particles, plant roots and organic matter.
Efficacy and longevity of biological amendments in a farming system
There is currently little evidence for efficacy of biological inputs within the broadacre dry-land grains context.
Benefits of improving soil biological fertility in a mixed farming system in Western Australia
This video shows a farmer's experience of managing soil for biological fertility.
Role of nematodes in nutrient cycling
Nitrogen cycling occurs because nematodes have a higher C:N ratio than their prey.
Percentage composition and number of organisms in soil
This video highlights the make up of communities of microorganisms in the soil.
Visualising the mass of soil microorganisms
Carbon, nitrogen, sulphur and phosphorus can be measured to calculate the weight of the microbial biomass.
