Farmers want to measure and record grass growth and quality in real time so that we can better utilize pasture for feeding animals.
The major challenges are:
Measuring the quantity of grass accurately across a farm in a timely way
Measuring the quality of grass – protein, fibre (NDF, ADF) and ME (metabolisable energy) through the season in a timely and cost-effective way
Planning which paddocks to graze on what date to maximize the growth and nutrient potential of the grass. (rye grass should be grazed when it has 3 leaves to maximize growth potential and nutrients)
Forecasting grass supply and demand ie how fast the grass is growing vs how much the animals are eating. So that in 3 weeks time we do not have old rank grass which the animals do not like, or conversely no grass to feed them!
- Understanding which paddocks of our farm are performing or under-performing, so that performance can be improved – water, fertiliser, new grass sown, pest problem, soil structure etc.
