In one sentence, describe what the following article is about: If you have tested your soil and found that it is too acidic, you can raise the pH by adding a base. The most common materials used to increase the pH of soil are compounds made from powdered limestone, or lime, which you can find at most home and garden store. Standard lime comes in four types: pulverized, hydrated, granules and pellets. Depending on your soil type and the amount of moisture in the ground, one of these compounds may be a good option. Pulverized lime is finely ground and more easily absorbed by the soil. However, it is more difficult to spread because it can clog the applicator. Granular and pelletized lime are easier to spread. However, it is not as effective at altering the soil pH. Hydrated lime should only be used with extremely acidic soils since it is more water-soluble and can quickly increase a soil's pH. Some lime sources contain micronutrients like dolomite, which is a mixture of calcium and magnesium carbonates. However, you should only use dolomitic lime if your soil is magnesium deficient. Do not add more magnesium to soils that are already high in it. The ash of burned trees is also quite basic and can add micronutrients like calcium, potassium, phosphate, and boron. Wood ash is not as effective as lime. However, it can dramatically increase a soil's pH over time. Because of this, you should monitor the soil closely as you apply wood ash. Keep the ash from coming into contact with any plant roots or germinating seedlings because it may damage them. Wood ash works well in sandy soil. In order to get the best results, you will want to till the liming material into the soil about two to three months before planting (usually in the fall or winter) so that there is plenty of time for the pH to change. The lime should be tilled into the soil's the root zone or the top 7 inches (18 cm) of soil. You can apply the lime by hand if you have a small enough piece of land. You can also use a spreader to apply liming material to a yard. You can use a rake or a rototiller to work the liming material into the soil. Because lime is not very water-soluble, tilling it into the soil will maximize its effect. Lime will have little effect on dry soils, so you will need to apply water regularly. Water activates the lime and helps it seep into the soil. Use a garden hose or sprinkler to apply water. How often you water the soil depends on the size of the plot of land and the amount of moisture already in the soil. Too much watering can leech other minerals out of the soil.
Summary: Pick a liming material. Think about using wood ashes. Apply the liming source. Water the soil regularly.

In one sentence, describe what the following article is about: Wait 5-10 seconds for the saliva to dry. Try to do this discreetlywhen you're aloneand not in a public place, or you may get strange looks from those around you. Avoid trying this test just after you've brushed your teeth, used mouthwash, or eaten something minty, as a freshly-cleaned mouth may give you inaccurate results. This is, more or less, what your breath smells like. If it smells unsavory, then you may need to improve your dental hygiene and overall health. If it doesn't smell like anything, then your breath probably isn't too bad--but you might need to try another self-test to be sure. Bear in mind that this method primarily pulls saliva from the tip (anterior portion) of your tongue, which is fairly self-cleansing. Thus, smelling your licked wrist will only tell you how the best-smelling part of your tongue smells--and most bad breath tends to originate from the back of the mouth where it meets the throat. You can wash the saliva off of your wrist, but don't worry if you don't have access to water or sanitizer since the smell will dissipate quickly as the skin dries. If your breath problems are relatively minor, you may not be able to smell much. If you're still worried, consider trying another self-testing method to give yourself a "second opinion". Use a finger or a piece of cotton gauze to reach deep into your mouthbut not so far back as to trigger your gag reflexand wipe the surface of your tongue at the back of your mouth. Any bad-breath bacteria lurking back there will come off onto the swabbing tool. Sniff the swab (your finger or the cotton) for an accurate sense of how the back of your mouth smells. This method may reveal bad breath more precisely than merely licking your arm. Chronic halitosis is caused by bacteria that breed on your tongue and between your teeth and most of these bacteria congregate near the back of your mouth. The tip of your tongue is fairly self-cleaning, and you may clean the front of your mouth more regularly than the back of your mouth. Try swishing with antibacterial mouthwashin the front and the back of your mouthto keep bacteria from hiding out on the back of your tongue. Gargle with mouthwash, if you can, to keep bad-breath bacteria from congregating in your throat opening. When you brush your teeth, make sure to brush your furthest back teeth, and be sure to brush your tongue and gums.
Summary:
Lick the inside of your wrist. Smell the inside of your wrist where the saliva has dried. Try swabbing the back of your tongue.
