The SOILpak project so far has concentrated on the grey and brown cracking clay soils used for cotton production. The aim of the project has been to collate the vast amount of information available on these soil types into a usable form. Many papers have been written and submitted to reputable journals and a lot of information resides within people's minds. The SOILpak team's aim has been to extract and gather the relevant information and present it in a single package.
