Hi! I am a freshmen and in my biology hns class we are doing a end-of-the-year 150 point plant project. We have to come up with our own experiment choocing one factor that affects plant growth and development. me and my friend (partners) have chosen soil pH. we are going to grow one plant in acidic soil, one in basic and one in normal soil. Problem: how much agricultural lime do we need (every day?) for a tiny brassica rapa (mustard) fast plant to change it's soil pH to alkaline??? and how much aluminum sulphate do i need (again, every day?) in grams, to change the soil pH of the soil to acidic. We kinda need urgent help, caz the experiment starts soon, and we haven't gotten exact measurements yet!! We can't guess, or the experiment will fail!! Someone, any gardener!! PLZ HELP US!!! THANK UUU
Good question -I've often wondered the same myself. I found this on wiki answers A lime has denser flesh than a lemon which makes it heaver. Limes contain more acid than lemons, and are more sour (but lemons are small, green and more bitter before they mature and then turn yellow and more sweet when they mature. So what's the difference between a lime and an immature lemon?) When put into a glass or bowl of water, a lime will sink to the bottom, and a lemon will float on the top. Could the difference in density be due to a difference in sugar content or a difference in lipid (oil) content? Lipids are less dense than water. Lemons are known for their lemon oil. Cut a lemon and feel the oil on the surface. A small, dense, green, immature lemon floats in water! I think they are close enough you could probably substitute one for the other depending on the scent you prefer.
