What are the corresponding land management guidelines relating to these ten key principles of soil biological fertility?
• Soil erosion should be controlled to minimise loss of soil organisms, • Plant organic matter should be retained to maximise nutrient cycling and soil aggregation processses, • Some disturbance of soil is necessary to maximise soil biological diversity, • Nitrogen fixing bacteria should be selected that match the host, soil characteristics (such as pH) and environmental conditions, • Inputs of nitrogen fertliser should be calculated to complement nitrogen cycling from organic matter • Inputs of phosphorus fertiliser should be calculated to complement and enhance the activities of arbuscular mycorrhizal fungi, • Any substance added to soil should be assessed in terms of its effects on soil biological processes and soil biological diversity, • Crop rotations and tillage practices should be selected to avoid development of soil conditions that enhance the growth and survival of plant pathogens, • The capacity of a management practice to produce a commercial product should be considered i
