Minimising risk of nitrate poisoning
Coming into autumn, maize and summer crops have been harvested/ grazed and farmers are planting their next crop or establishing new permanent pasture.
Last month saw the annual release of the DairyNZ Economic Farm Survey and the NZ Dairy Statistics.
These fascinating documents contain a wealth of data on the average physical and financial performance of 316 randomly selected owner-operator herds during the 2016-17 production season.
Several things stand out in the survey, the main one being how well farm profit and return on asset have recovered after the previous season’s very low payout.
During the 2016-17 season, on average, farmers received $5.79/kgMS for their milk. As a result of the tough previous season, farmers have learned how vital cost control is and despite a 48% lift in payout there was virtually no lift in farm working expenses/kgMS.
Some commentators may be tempted to use the last two season’s data to push to de-intensify dairy farms, saying that high input farms are less profitable than lower input farms. However, such a conclusion would deny the long-term results of the survey.
An analysis of the past twelve seasons (Table 2) shows that on average, high input systems made more money, had the highest return on assets and now also have the lowest closing term liability/kgMS.
The data is quite clear. Over the last 12 years, on average, high input systems have made the most profit/ha, have had the best return on assets and equity, have had the best growth in equity and are less financially risky in terms of their closing liabilities/kg milksolids.
Intensification is not wrecking the profitability of NZ dairy systems. And going on the previous 12 seasons’ figures, I predict that this season’s payout will reinforce the decision many farmers have made to intensify, i.e. their decision was correct.
However, as we now know, profitability is not the only issue farmers are facing.
In next month’s column I hope to cover things that farmers can do practically to reduce their environmental and biosecurity risks.
