Welcome to our Soil Wealth Darwin demonstration site. Located about 50km out of Darwin, our Lambells Lagoon site is in the heart of the Top End's horticulture district. With local grower David Boehme, we'll be exploring some key soil health issues including boosting soil carbon, integrated pest management and the value of cover crops.
David was out just as the Darwin wet season started in December sowing cover crops to protect the soils from heavy rainfall over the summer. These crops will also act as a green manure that will boost soil carbon and provide nutrients for the coming year's eggplant crop.
Despite a drier than expected summer, the cover crops are progressing well with good growth. Both the cow pea and the mung bean will boost the nitrogen content of the soil while the sorghum with its greater bulk will contribute more carbon to the soil.
