Why deep test? There are a number of benefits in deep soil testing.Exceptional winter crop yields in 2020 across New South Wales, Victoria and parts of South Australia will have seen crop nutrient removal rates at their highest levels for years for some regions.Under the excellent soil moisture conditions that prevailed in 2020, mineralisation of organic matter and potential leaching of mobile nutrients like nitrate and sulfate down the soil profile, coupled with the high crop removal rates could see many soils with N and S status below optimal levels.Deep soil test now to ensure you understand current soil nutrient status and the fertiliser needs to get your crop off to a strong start and sustain vigour throughout the season. Nitrogen and sulfur levels can fluctuate throughout the start of the season with sporadic rainfall across agricultural areas so matching sampling times as close to possible to peak crop N and S demand can lead to greater confidence in predicting N or S requirements. |
