<p>Louis Schipper talks to Bryan Crump on RNZ Nights about soil carbon. He talks about soil organic matter, soil density, nutrients (nitrogen, phosphorus, sulphur), land use and the ways we can store more carbon in soil to reduce the amount of carbon dioxide in the atmostphere without reducing food production.</p>
<p>Louis also talks about the<a href="http://4p1000.org/understand"> 4 pour mille </a>initiative and its challenge to increase carbon content of soils by 0.4% per year to offset fossil fuel emissions.</p>
