Sweetcorn - 8 Dec 2020

Comparing the Biomineral production system with a range of fertiliser strategies in sweetcorn.

This Case Study - 

1. The Biomineral treatment produced 32% more premium grade sweetcorn than the recommended best management practice (NPKMg) and had the highest marketable yield. 

2. The Biomineral treatment had between 15 and 30% less reject cobs when compared with the other treatments. 

3. Biomineral sweetcorn experienced the same level of pest pressure as the other treatments without requiring any chemical intervention. 

4. The Biomineral treatment generated the greatest revenue of all treatments.

​

Aim :

​

To compare the performance of the Biomineral production system with a range of fertilizer

strategies for producing sweetcorn in Carnarvon, Western Australia.
