At the trails there are all different types grass sections. In our groups we were allowed to get a sample to do a test on. The soil that my group has is phalaris and RC ( red clover ) In our groups we did a test on the soil. 2 groups did nitrogen, 2 groups did potassium and 2 groups did phosphorus. My group did potassium. The results that the tests work by is colour. Potassium's base colour is black. If the colour turns black it is low in potassium. If it turns smokey grey than it is medium in potassium. And if it turns light grey than it is high in potassium. Our one turned in between high and medium.
At the nursery there were willow trees and. What they did at the nursery was they let the tree grow, and when they will cut off the biggest trunk off the tree and put it back in the ground, and it will re grow it's self into another tree and they will keep repeating it over and over again. Just down from the nursery there was a river. The river was quite dirty in regardes of the flooding. 
We also went up to a hill and on top of the hill there was a measuring machine type thing that weighed and measured the rainwater. There was also a few cages on the hill. The cages were me
nt for measuring the grass. Renee one of the people who worked at whangara farms, one of her jobs was to measure how much dry matter there is for the animals. In the caged space she presses down with her special tool 5 times. In the four corners and in the middle and that measures how much dry matter there is for the animals to eat. She does that prosess for each cage, she does it one time and then goes back in two weeks and does it again in the same spot then she moves into another spot.
