Maize doused and down after a monsoon month

MONSOONAL levels of rainfall throughout Western Bay of Plenty threaten both maize silage and grain supplies this autumn.

Bill Webb, director of Bill Webb Feed Supplies near Te Puke, said his property at Ohauiti Western BoP has had 3500mm of rainfall in the past 12 months, putting it at a level comparable to West Coast’s Hokitika.

Even the drier Rangitāiki

Plains area between Te Puke and Whakatāne has received 2500mm, about double its annual average.

On average, over the monsoon season India receives about 250mm in both July and August, about 70% of its annual average. This year throughout much of the Western Bay of Plenty, January’s rainfall alone will total between a third and half of the 1200mm it usually receives in a year.

The latest event has left some crops washed out and useless for silage harvesting.

“We have one block of 8ha near Te Puke where the water came up 24 hours ago to above fence-post height in the crop. It has deposited mud throughout the maize, and it’s going to affect its ability to pollinate, and will also mean we can’t even turn it into silage if all this silt’s through it,” Webb said.

In other instances, farmers contracting to supply Webb with maize this season have had two and in some cases three attempts at getting a crop planted, only to lose it this time around.

“I have never seen this level of rainfall in my time. Some crops did not get planted until early Christmas-New Year.

“Potentially the grain take for the area will be down from normal. And with farmers struggling to get maize, silage in will be down too. It has definitely hit growers hard.”

At a cost of $3000 a hectare to establish maize, turning around and replanting put growers on a fast track to barely breaking even, while a third time was a loss.

Ex-Federated Farmers Bay of Plenty president Darryl Jensen said he is about to feed his 9ha of maize to his cows as it is. Such was the damage it cannot be salvaged for silage. It also lacks any cobs because it went in late, after the pre-Christmas deluges.

Jensen said this has been the wettest season any farmers of his generation have witnessed.

DOUSED: Monsoonal rainfall throughout Western Bay of Plenty has left many growers giving up on their second or even third attempt at getting a crop established this year.

One farm consultant tells of dairying clients whose cows should be producing 1.7kg MS per head per day scratching to achieve 1.0, and even then only achieving that with 60% of their diet an expensive supplement.

“The green grass is certainly there, but it really lacks feed value. The lack of maize silage heading into autumn is going to impact on herd body condition, and that will flow into next season now too,” Jensen said.

Horticultural operators have also been hit in the latest deluge, with at least 30 orchardists on Number 4 Road near Te Puke losing access to the town due to a critical bridge being blown out by intense flooding – only eight weeks before harvest starts.
