The absence of periods of significant rain has allowed ground preparation for cropping to get underway, particularly on the Heretaunga Plains. Apart from a mild spell at the beginning of August, cool and overcast conditions over the remainder of the month would have slowed down flowering in summerfruit. Early flowering apple varieties are showing bud break. As is usual in spring, fruit growers will be monitoring weather conditions closely for frost and pest & disease risk. Gillian Mangin & Annette Carey Ministry for Primary Industries Policy, Ahuriri The August Roundup Cooler, overcast weather in recent weeks has resulted in feed levels becoming tight on many sheep & beef farms. This has seen the market for store stock go quiet. Relatively benign weather over the first half of winter means that stock are in good condition. Although there were occasional cold rainy periods, there have been no significant weather events. As a result, lambing seems to be going well. The dairy season is off to a very good start although pasture covers are only fair to average. Calving went particularly well and cow condition and performance is above average. Farmers are keeping a close eye on costs in light of the forecast pay-out. With good soil moisture levels, some warm sunshine STATE OF OUR ENVIRONMENT > AUGUST 2014
