Earth Science Unit Study
Week 17: We tested the acidity of garden soil with cabbage water.
Acidity levels in soil are one variable which can lead to a successful or unsuccessful garden. Most plants prefer neutral PH levels around 7. Soil located under pine trees is often acidic and using nitrogen fertilizers can lead to acidic soil issues.
At our previous residence there was a pine tree located very close to a plum tree which never produced any plums. One year the pine tree was chopped down, and the next year the plum tree was loaded. At our current residence there was a similar incident. A garden located near a pine tree produced very little and contained few worms and life. One year the pine tree became a Christmas tree for the local church and the next year the garden thrived.
