| Abstract | Soil is one of the earth’s greatest carbon sinks that sustains plants, animals, and humanity. However, agricultural managements including chemical fertiliser applications can affect the soil health. In majority of cropping soils across Australia, there has been a 2-3% per annum decrease in the soil N reserves and low in phosphorus (P) due to extensive weathering. Potassium (K) is low or deficient on many of the sandier soils, and higher K removal can occur on soils across intensive grazing and intensive horticultural crops. The use of organic fertilizers (processed organic waste materials) can constitute a sustainable strategy for improvement in soil structure (physical, biological, and chemical properties), increased soil C storage, improved water and nutrients holding capacity to achieve productive yields and for mitigating climate change. Considering the above, the Soil CRC (https://soilcrc.com.au) is bringing together scientists, industry, and farmers to find practical solutions for Australia’s underperforming soils. As part of Soil CRC projects, a new initiative entitling “Assessing economic feasibility and benefits of adopting high-grade organic fertilizers recovered from waste streams” has commenced in 2022. This project will assess the cost effectiveness of using waste products such as manure, dairy farm waste, compost, and biochar as an organic fertiliser. It will be evaluated in broadacre and other cropping systems in NSW, to inform farmers to understand the economics of applying organic fertilisers derived from waste, thereby leading to greater uptake and application of recycled organic materials. This paper reviews advances in key aspects of economic feasibility and benefits (and risks) of adopting high-grade organic fertilizers. The second objective of this paper is, to provide a case study example, where APSIM (Agricultural Production Systems Simulator) model was used to simulate how farmers can increase productivity and farm income using organic fertilisers in comparison to inorganic fertilisers. |
