Water, soils and wallowing

Deer have specific natural needs and behaviours and if incorrectly managed, deer can threaten the quality of water and soil, cause erosion, compaction and pugging of soils, and the consequent runoff of nutrient, sediment and coliforms will result in contamination of waterways with undesirable behaviour including excessive pacing, wallowing, and digging in soils.

Phosphorus fertiliser use

Phosphorus (P) is the most expensive nutrient. It is also a pollutant when it gets into waterways. Careful management of P is essential to ensure optimal economic and environmental outcomes. The key is to farm at the economic optimal soil Olsen P – farming below the optimal means less profit and farming above the optimal means greater losses of P to the environment.

Natural seepage wetlands and nitrogen losses

They may be generally disliked by farmers and thought of as troublesome ‘bogs’, but seepage wetlands have proven highly effective at preventing contaminants from reaching waterways.

Soil Testing and Fertiliser Use

Nutrient value of effluent

The average dairy cow produces about $25 worth of nutrients annually as farm dairy effluent (FDE). For a 400 cow dairy herd this represents about $10,000 of nutrients annually. If these FDE nutrients are used effectively then this significantly reduces the fertiliser bill. FDE is therefore a resource not a waste product.

Managing soil fertility on cropping farms

Broadacre cropping is dominated by the production of cereal grains and pulses which are the staple crops for our population. As such society demands a reliable supply of high quality products. To meet these requirements while achieving an economically viable livelihood arable farmers have tended to invest in heavily mechanised high input crop production systems for which the maintenance of strong soil fertility is critical.
