Trivia

Four years later, Rob Baur of Lake Oswego, Oregon was able to graft a tomato plant onto the root of a tobacco plant, creating an actual tomacco with no side effects like the ones seen here.
The title is based on the refrain of the child's repetition and memory learning song "Old MacDonald had a Farm" or "E-I-E-I-O".

Soil pH or soil reaction is an indication of the acidity or alkalinity of soil and is measured in pH units. Soil pH is defined as the negative logarithm of the hydrogen ion concentration. The pH scale goes from 0 to 14 with pH 7 as the neutral point. As the amount of hydrogen ions in the soil increases the soil pH decreases thus becoming more acidic. From pH 7 to 0 the soil is increasingly more acidic and from pH 7 to 14 the soil is increasingly more alkaline or basic.
