Reducing the risk before planting Reducing inoculum is vital to managing crown rot... Unfortunately cultivation spreads infected residues, which may increase plant infection rates counteracting any benefits from increased residue breakdown...

Soil organic matter contributes to a range of biological, chemical and physical properties of soil and is essential for soil health... Soils rarely reach their theoretical potential for organic matter storage (see Figure 1.7)... In soils with low clay content the amount of humus and resistant soil organic matter is increasingly important to nutrient exchange because its large surface area gathers (adsorbs) cations from the soil solution, holding nutrients that would otherwise leach...

Soil organic carbon makes up about 58 per cent of the mass of organic matter and is usually reported in a soil analysis report as the concentration (i.e. per cent) of organic carbon in soil (see Chapter 1 for more detail)... If a soil has a significant amount of gravel or stone material, this fraction is removed before analysis with the final soil carbon or nutrient assessment being only representative of the mineral component of the remaining soil... Understanding how organic matter cycles through the soil and what drives its accumulation and loss is critical to maintaining it at optimal levels within agricultural systems...
