Fractional reserve banking is a system where banks hold less than 100% of their deposits as reserves.Let r = fraction of deposits held as reserves.Then bank loans out $ (1-r)*D. So, now, D is still $1000. But, C = $800 (borrower who got the loan now has $800 in currency).
Liming a lawn can help your grass grow better. When lawns are weedy, patchy in spots or turn yellow, it may be a sign that the pH balance of your yard is out of whack. One of the primary methods of correcting the problem is to add lime to your lawn to restore depleted nutrients and repair the damage.ime may be needed if the pH of your soil is too low for the turf species you want to maintain. To determine the pH of your lawn, purchase a pH test kit from a garden center, or check with your county cooperative extension service to see if it offers free testing.
1 Use a spreader to distribute the lime evenly across your lawn. 2  If your lime is in pellet-form, feel free to use your hands instead. 3  Lime does not move horizontally, so you need to be careful with your application.4  Consider spreading half the lime in one direction and the other half in the opposite direction. As we said before, fall is the best time to apply lime. 2  If you lime your lawn before the first frost of the year, the freezing/thawing pattern of winter will help the lime seep into the soil. 3  Donât apply lime when your soil is very wet and avoid windy days, especially if your lime is in powder form.
