CHICKEN manure spading on Stuart Pope’s Karoonda property targeted non-wetting sand,a catchment area for seeps,and showed positive results.

Mr Pope firstnoticed seeps developing almost a decade ago and said they haddegradedarable cropping land.

“Our main issue has been deep, non-wetting sand.We’ve done a bit of clay spreading, delving and even tried growing millet one year on the non-wetting sand and haven’t had much success with anything,” he said.

The land for the trial was spaded with different rates of chicken manure and the subsequent barley yield, quality and germination exceeded expectations.

Trials consultant Chris McDonough said there was sparse germinationand roots struggled to establishdeep into the control areas.

“The control areas were reaping1-1.5 tonnes ahectare last year. Where we spaded withoutchicken manure was 2-2.5t/ha. Where we spaded with 5-6t/ha of chicken manure it went up to 3-3.5 t/ha. It was quite remarkable,” Mr McDonough said.

“Mallee sands are oftencompacted between 20 centimetresand 40cm so roots can’t break through them.We’re breaking that compaction and because chicken manure is very high in nitrogen, phosphorous, sulfur and trace elements you’re mixing nutritious organic matterthrough the top 40cm, and that ischanging the fertility of the soil.”

Mr McDonough said the moisture-holding capacity was much better in the spaded chicken manure soil than the control area, which means the sand is less likely to contribute to seep recharge.
