The Central West Local Land Services has released a series of online videos showing how farmers can test and understand their soil.

The tests shown are a simple and inexpensive way of understanding what is happening below.

The video series is an easily accessible resource for farmers unable to attend field days or training. They also are a useful refresher for people who have attended training.

Soil is one of a property's most valuable assets. It needs to be managed correctly for a productive and sustainable farm business, according to Central West Local Land Services Cropping Officer Neroli Brennan.

"Your soil is your business's greatest asset, but if it is not carefully understood and managed it can be your greatest constraint to production," she said.

"Getting to know your soil is easy, and it doesn't have to be expensive.

"If you understand what you are working with, you can make informed management decisions."

Ms Brennan is encouraging farmers to look at their emerging crop now and ask themselves whether they need to carry out some testing.

"If your crops have struggled to germinate or you have poor plant establishment and persistence, it may be time to look underground for your answers."
