Boosting productivity and reducing environmental harm
Dairy Holdings has been on a journey to significantly reduce the amount of water and nitrogen fertiliser it uses as part of a five year strategy to limit environmental impacts – while improving productivity. Precision-ag technology company, CropX, has recently partnered with Dairy Holdings to help it meet those targets. Since implementing its strategy in 2017, Dairy Holdings has reduced water use by one third across its 60 farms spanning 20,000 hectares. This has been achieved by modernising irrigation systems, introducing water meters to measure annual consumption, and installing soil moisture monitors to guide irrigation decisions. Dairy Holdings has also reduced fertliser use to well within the new nitrogen cap regulations of 190 kilograms per hectare (kgN/ha) at an average of 172 kgN/ha for the 2021/22 season. Despite these big cuts in water and nutrient inputs, pasture growth has, in fact, improved. This has resulted in a massive 90% decrease in the quantity of purchased supplementary feed per year. Underlying all of this positive change has been a need for Dairy Holdings to understand, in precise terms, what is happening in the soil of its farms. This allows farm managers to make informed decisions about how much water and nutrients to apply to the land and when, to enable optimal grass growth with minimal inputs. Initially, as part of its irrigation upgrades, Dairy Holdings installed soil sensor tapes below the ground under the irrigators, which farm managers could monitor daily to inform irrigation decisions. But this system required more active management, was very time consuming to use, and often led to inconsistent results. Dairy Holdings needed one, standardised, automated, online, easily accessible, and transparent soil moisture monitoring system with data captured from across all of its irrigated farms. This would guide optimum water […]
