@GrasslandSocSA @BerjakDonna @kzndard Are there Italian ryegrass cultivars that persist into the second autumn in the KZN Midlands climate, and could they have a comparative yield to Westerwolds planted annually?

@CharlesfordFarm wonderful setting, great little farm shop

Heidi Hawkins clearly debunks the notion that fire destroys soil carbon. Moderate burning (biennial) will keep stable forms of carbon in the ground in mesic montane grassland.

@GrasslandSocSA @BerjakDonna @kzndard Data shows the importance of using mixed pastures to alleviate fodder flow challenges and to have more persistent pastures reducing need for annual re-establishment

@GrasslandSocSA The famous physicist, Freeman Dyson was the first to suggest, in 1977, that we could combat climate change by planting 1 trillion trees. He knew nothing about grasslands or trees.

@GrasslandSocSA @grasscraig Could this mean that in the long term there could also be effects on the nutrient balance in mixed and sweetveld or would growth/nutrient extraction still be too limited by rainfall?

Think you have a soil biology problem? Think again...it's more likely you have a soil habitat problem.
And don't fall for alternative methods...a few proven practices will often do.
Don't overthink your soil biology. My latest...
