jarrah biochar

Catalogue: Ground Cover
A Western Australian study shows that applying biochar made from wheat chaff and eucalyptus wood may have some negative effects on sandy soils.. To assess the impact of biochar on nitrogen leaching in a sandy soil from Meckering, WA, Mr Dempster ran another glasshouse trial and compared the results to those achieved by adding clay - another ameliorant being used by some growers to enhance soil fertility... The results showed yield decreased significantly from 2.1t/ha to 1.7t/ha when biochar was banded into the subsoil...

Although biochar addition to soil did decrease inorganic N leaching, soil N mineralisation either decreased or did not change... The application of pyrolysed organic matter or biochar to soil can remediate decreased SOM and sequester C. The application of biochar to soil has also been shown to improve soil fertility and enhance yields of crops such as maize, wheat and peanuts... As biochar addition to soil can increase microbial community size and activity, previous research has hypothesised that this mechanism may be responsible for enhanced N mineralisation rates and contributes to the demonstrated improvements of N fertiliser use efficiency (up to 90%) in glasshouse-based agronomic research...
