Watch: setting up a clay and silt trap in the fields
As we enter the depths of winter and with rainfall amounts and frequency returning to normal levels, we set up a basic trap to measure soil runoff during the wet period.
Organic manures are more than just a source of nutrients
The huge level of variability in the nutrient content of organic fertilisers make their other benefits for the soil even more important.
Manures are best recycled through the land
Manures can be very useful additives to tillage soils, but recent problems with botulism and an inability to use the actual nutrient levels when tested could make their use less attractive in future.
Soil: will it run out?
Soil contains between one third and one quarter of all living organisms on the planet, but is degrading at a rapid rate. The National Biological Farming Conference looked at the reasons behind this.
