- Carbon absorption from the perennial grass component evolve
into highly stable forms of soil carbon, while the short-term high
sugar forms of carbon (labile c) exuded by the cereal crop
stimulate microbial activity.
78. The Benefit
- Highly efficient C4 perennials are extremely efficient
converters of the suns energy whilst maintaining low water
use.
- Microbial activity is encouraged year round; soil temperatures
are greatly reduced by the microclimate created.
- Wind and weather erosion is halted.
- This allows huge savings on knock down herbicides and bare
soilfallows.
79.
- When levels of humified soil carbon increase, so too does
porosity, aggregate stability and SWHC.
- The conditioning of soil at depth by perennial grass roots can
remove many of the sub soil constraints that often develop when
levels of biological activity are diminished by bare stubble fallow
and annual cropping practices.
- SWHC below the normal annual crop root zone-significantly
increases the bucket depth and its capacity.
