GRAZING a sprayed-out pasture paddock for fallow prior to sowing is another opportunity to make money.
“It’s an opportunity to make money from this phase in a rotation,” says Ag ‘n’ Vet consulting animal nutritionist Nicola Brazier, Euchareena.
She said even when pasture paddocks had been sprayed out in preparation for the next season, there was still an opportunity to get some grazing off them.
“These plots have been sprayed out and will then be ploughed back into soil in preparation for next year’s crop after just one year as pastures with a mix of mainly lucerne and clover,” said Ms Brazier, who is pictured last year in trial plots investigating the impact of grazing.
“There is a trial site here that has some fescue as well and that has been really interesting because the starting nitrogen for the next crop in this plot is exactly the same as the plots of lucerne and clovers.
“That’s very exciting from an animal point of view because it means we can have some grasses in the mix to better balance some of those pastures with high legume content.”
Ms Brazier said the pasture would be lower in protein, but still offered a reasonable source of feed going into the summer months.
After being sprayed, fescue paddocks would need to be supplemented if growing stock were put onto them as they would need a source of protein.
“Maybe some lupins or peas and beans in a lick feeder or alternatively a loose lick or a block that has evidence of urea or protein source within,” she said.
“You could put some dry stock onto these paddocks, or stock you just need to maintain would do very nicely on feed like this.
“There are ways of having this pasture phase in the cropping rotation as there is always stock that can utilise it.”
Ms Brazier said it was advisable to read spray labels carefully to ascertain any with-holding period between spraying and the introduction of livestock to the paddock.
