Machine learning can take historical data, (the more detailed the better), to create its own creative solutions to problems and suggest them to the producers. 

Precision Agriculture Techniques

Variable Rate Technology (VRT) in Precision Farming

Variable rate technology (VRT) is a system that allows farmers to apply fertilisers, seeds, water, pesticides, and other chemicals at various rates, often based on real-time data. When implemented following sustainable practices, implementing VRT in grazing systems can improve pasture quality and enhance animal nutrition.

Optimising Inputs: Understanding Variable Rate Technology

Variable rate application can be implemented for both crop yield improvement in precision agriculture and feeding systems in precision livestock farming. In general, VRT helps optimise land production while reducing input and labour costs. 

With more sophisticated inputs and automated applications, VRT enables farmers and graziers to maximise efficiency, improve yields, and easily promote sustainability.   

Implementing VRT for Crop Yield Improvement

To start implementing VRT, begin with the essential list below to optimise yield and reduce waste: 

  1. Collect data (soil maps, yield maps, and other relevant information to understand the spatial variability) 
  2. Choose the right VRT system (Map-based vs. sensor-based)
  3. Invest in equipment and train the farm staff 
  4. Update and refine yield maps to collect trends and patterns
  5. Monitor and evaluate outcomes to implement changes
