Changing the colour of your hair is one of the easiest ways you can recreate your appearance. If you want to disguise yourself and blend in, it's a good idea to choose a hair colour that seems natural and common. Shades of black and brown are good choices in this regard. Pay attention to the region. If blonde or ginger are more common in the area that you are in, dye your hair blonde or ginger. Accessories like hats and sunglasses work well to obscure someone's regular appearance. Sunglasses and a hat by themselves are a great casual disguise. Other accessories like jewellery and bowties won't necessarily obscure your appearance, but they'll add a different tone to your look that others may not be used to seeing from you.  If you are known to dress conservatively, putting on a bunch of jewellery or flashy colours will disguise your typical identity, even if the get-up draws attention to you otherwise. Keep the accessories simple and discreet. If they are too eccentric or blingy, they will attract attention, causing people to take a closer look. They may end up recognizing you! You can add years to your appearance by using makeup. Squint and bit, and lightly pencil in the creases caused by your squint. It's important to keep these cosmetic changes subtle. Otherwise, it will be easy to pick up on the fact that it's a disguise. If you are elderly, smooth out your facial creases with skin foundation. Dying your hair to mask the grey or white will also help disguise your identity. Walk for a bit in your typical manner, and identify your walking personality. Next, change up the way you walk to suit your intended disguise. You can tell a fair amount about a person's character and mood by their gait, so this may keep others from recognizing you. For example:  If you're trying to look older, walk slower than you normally would. Consider shuffling or dragging your feet. If you're typically a fast walker, disguise your identity by walking slowly. Likewise, you should speed up your gait if you're a more leisurely walker. If you are in an area with video surveillance, you may want to take measures to change the appearance of your facial structure. Puff out your cheeks and stuff your nostrils with toilet paper to change the shape of your face.  This technique can help you escape any facial recognition technology that may be used to track you down. Avoid doing this for long periods of time as the actions (like puffing out your cheeks) may end up drawing more attention. Using a fake moustache is arguably the most common and famous type of disguise around. You can buy some facial hair from a costume store. Apply some spirit gum (a substance used to affix fake facial hair to actors, not SPENT gum, like chewing gum)  to the area you want to have bearded, then set the disguise on your face and allow it some time to settle.  If you need to disguise yourself quickly and are known for your facial hair, quickly shaving it off will transform your appearance. This can possibly work even if you're a female. You will need to use contouring to make the rest of your face look more masculine, however.

Article: to find its nutrient and pH levels. Knowing the pH level of your soil is important because different plants thrive under different pH levels. It's also helpful for you to know the nutrient levels so you know what you need to add to the soil to help the tomato plants thrive. Use a commercial testing kit to collect and test a sample of the soil where you plan to plant your tomatoes.  Tomatoes grow best in slightly acidic soil, with the optimum pH level being between 6.2 and 6.8. Soil that falls below 6.0 is too acidic for tomato plants to thrive. An even balance of nitrogen, phosphorus, and potassium is necessary for your tomato plants to produce lots of healthy fruit. Too much of 1 nutrient can affect the health of your tomato plants. If the pH of your soil is below 6.2, mix in crushed eggshells at a ratio of 1 pound (0.45 kg) for every 100 square feet (9.3 m2). For soil that has a pH above 6.8, you need to make it more acidic. Mix together equal parts water and cold coffee in a water can and apply it to the soil.  For example, if you have a tomato garden that is about 20 square feet (1.9 m2), then mix in about .2 pounds (0.091 kg) of eggshells. Turn the soil over and mix it up after you apply the eggshells or coffee mixture. Retest the soil to see if the pH level is between 6.2 and 6.8 before you plant your tomato plants. Your soil needs to have an even ratio of nitrogen, potassium, and phosphorus for your tomato plants. If you have a low amount of nitrogen, add in a natural source, then retest the soil to make sure the levels are even. Combine the nitrogen source with the top layer of soil and compost by mixing it together with a shovel.  Natural sources of nitrogen include alfalfa meal, blood meal, feather meal, and fish meal. You can also add artificial nitrogen fertilizers like ammonium nitrate or ammonium sulfate. Bone meal is a great organic source of phosphorus that you can add to your soil raise the levels of that nutrient. Mix in the bone meal with the soil then retest it to make sure the levels are even with the nitrogen and potassium levels.  Artificial phosphorus fertilizers include rock phosphate and superphosphate. You can find bone meal and phosphorus fertilizers at garden supply stores, nurseries, and online. If you need to elevate your potassium levels so they're even with the levels of nitrogen and phosphorus in the soil, add some wood ash or granite dust and mix it in with the top layer of soil. After you combine it with the soil, retest it to make sure the levels are even.  You can use potassium sulfate or rock sand as artificial fertilizers that will raise the potassium content of your soil. Find wood ash, granite dust, or artificial potassium fertilizers at local nurseries, home improvement stores, or online. No matter what fertilizers or nutrients you plan to add to your soil to prepare it for tomato plants, you need to add them to the top layer of the soil that you tilled for your garden. Mix in the compost or nutrients well with the soil so the roots of the tomato plants can start to absorb them as soon as you plant them. Turn the dirt over with your shovel to help combine the nutrients, compost, and soil. If your soil is lacking in nutrients, you can add a continuous-release fertilizer that will provide the nutrients your tomato plants need. Artificial fertilizers are less natural and organic, but they quickly raise the nutrient content of your soil. Mix in the fertilizer with the top layer of soil and compost.  Choose a fertilizer that has an even ratio of potassium, phosphorus, and nitrogen for your tomato plants. You can find fertilizers at garden supply stores, plant nurseries, or online. Popular continuous-release fertilizers include Miracle-Gro, Tomato-tone, and Fox Farm Tiger Bloom. Add the artificial fertilizer according to the directions on the packaging. Different fertilizers have different concentrations and application methods. The compost will add a small but continuous amount of nutrients and will help the soil hold water and keep the roots from drying out. Cover the top of the soil with a 1 inch (2.5 cm) layer of compost, then mix it into the soil.  Compost will also help any fertilizer that you add stay in the soil until it's needed by your tomato plants. You can find compost at garden supply stores, nurseries, or online.
Question: What is a summary of what this article is about?
Test the soil Adjust the pH with eggshells or coffee so it's between 6.2 and 6.8. Mix in a natural source of nitrogen into the soil if needed. Raise the phosphorus content by adding bone meal to the soil. Increase the levels of potassium with wood ash or granite dust. Place any nutrients you add into the top 6 inches (15 cm) of soil. Mix in an artificial fertilizer for an easy way to increase the nutrient content. Add compost to help the soil retain moisture and nutrients.
