Michael Tarabula 11-3-2005 Jethro Tull’s Seed Drill Jethro was born in Basildon‚ Berkshire in 1674. He is widely known for his invention of the seed drill that improved agricultural ways greatly. The seed drill prevented farmhands from broadcasting the seed‚ which is just throwing the seed out in no form‚ and made it where the seeds were put in orderly rows. The seed drill allowed the farmers to make rows of seeds instead of broadcasting. This made it easier for farmers to weed

radish seeds with tap water. This was an important part to have in the experimental design because I was able to compare this to the other bags that contained coffee‚ ammonia‚ and vinegar. With the results that I collected‚ I was able to gather more observation and data. 2) The independent variable in this experiment was the pH level of the solutions‚ whereas the dependent variable was number of seeds that each solution was able to germinate. Some control variables were the amount of seeds given

vegetables is still as difficult today as it was in the 1700’s. The invention of the seed drill was really one of the most useful inventions in that time because it helped make the farmers work easier. The seed drill was created by Jethro Tull to make the lives of the laborers easier and not waste the seeds of what could’ve been a surplus of food. The seed drill was a mechanical machine that would plant the seeds in rows rather than the method used prior where farmers would scatter them wastefully

Carol Delaney‚ in her book on Turkish village society‚ The Seed and the Soil‚ describes how virginity testing is related to the way that Turkish villagers conceptualize and explain the reproductive process. They see reproduction as analogous to the planting and growing of crops; the man provides the “seed” with his semen‚ and the woman serves as the “soil” in which the seed germinates and grows. As a metaphor for reproduction‚ the idea of the seed and the soil provides villagers with a way of thinking
