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.
There are many different types of lime, but they all work to do the same thing: raise soil pH to the neutral range in order to unlock nutrients in the soil and make them available for plant uptake. But, when it comes time to put lime on your lawn or garden, the choice of which lime is best for you can be overwhelming. Choosing the right lime will help you maximize results and avoid burning your lawn. Below is an explanation of the various types of lime, and how they stack up against each other.
