AllAboutCompost

• Compostmustbemature,sterile,andpathogen-free.

• Compostdoeswonderfulthingsinoursoil,byimprovingthesoil’swater-holdingcapacitytherebyreducingourneedforirrigation,andimprovingthesoil’sstructuretherebyreducingerosion.

• Compostiseffectivelyaslow-releasefertilizertherebyrestructuringourfertilizerprogram,aswellas,providingabufferforfertilizerimbalances.

• Compostcanimproveplantroothealth,andaidinthesuppressionofplantdiseases.
