2018-19 soybean black soil Casino

2018–19 summer: Soybean on black clay, Casino

The North Coast of NSW is one of the most consistent and reliable soybean producing areas in Australia, usually achieving high quality grain with good yields (>4t/ha) from rain-grown crops. Very dry conditions this summer have seen an unusually small area of soybeans sown and those crops that were planted have struggled through very dry growing conditions.

In crop rainfall to-date is 30 mm, biggest single fall being 9 mm, however only amounts above 10 mm are considered effective on the North Coast.

The crop history information and photos have been supplied by the grower.

Location: Rainfed paddock, Casino

Crop out of the ground. Planted 25 Nov 2018

Great early growth. Making the most of stored soil moisture.

Week 6 – Sprayed out volunteer rice. Leaf damage evident from earlier caterpillar presence.

With no effective rain falling during the growing season this crop is doing well to survive.

12 weeks in, starting to slow down.
