Скачать или смотреть Mapping the Future: Updating Queensland's Phosphorus Landscape

Phosphorus is an essential nutrient for cattle required for skeletal growth, muscle development, metabolism, and milk production. A deficiency increases the mortality rate in cows, reduces growth rates, and reduces calf weaning weights. Knowing if your country is deficient or not, and whether you need to supplement is vital in managing northern Queensland properties.

A map of available phosphorus (bicarbonate extractable) across the state of Queensland has recently been updated to include the Cape York, Northern Gulf and Southern Gulf catchments, and to be more spatially accurate.
In this BeefConnect webinar recording, Jim Fletcher (Senior Beef Extension Officer, DPI), Stephen Leo (Senior Scientist, DETSI) and Grant Stone (Principal Scientist, DETSI) collectively discuss:

• Selecting sites and soil sampling
• Spatial modelling and map production process
• Improvements made on the new map
• Overview of the variability in phosphorous across land types in the sampled catchments
• How to get a FORAGE Indicative Soil Phosphorous report for your property
