Comments Off on How to grow 10 foods from kitchen scraps

Meal plans and grocery lists, the cycle never ends. While some of your foods may come from carefully cultivated seeds or seedlings planted in your garden , did you know that you can grow food from food? You have probably heard that romaine lettuce regenerates easily if the base is placed in water, or that basil and cilantro cuttings will turn into entire plants, but there are many, many more foods that will grow from your kitchen scraps. Here’s a highlight reel. Bon appetit! Garlic Growing your own garlic is easy as well as rewarding. Start with a healthy bulb of your favorite varietal. Separate the bulb into individual cloves. Then place each clove into the soil with the pointy end facing upward. Allow 4 to 6 inches between each clove for a bulb to form. Cloves should go into the ground in the fall, before the first frost, and will be ready to harvest in the spring. After harvest, hang dry the entire stalk. You can braid stalks together for compact storage. During the winter and summer months, you can plant cloves indoors and enjoy the garlic greens, but don’t expect bulbs to form in these conditions. Related: 6 surprising uses for garlic you probably didn’t know about Peppers Seeds from both sweet peppers (red, green, yellow and orange) and hot peppers (jalapeno, habanero) can be dried and used in the garden next season. Be sure to choose seeds from healthy, non-hybrid plants for the best chance of success. Remove the seeds from a well-matured fruit and lay them out to dry. Store dried seeds in a cool location, like your refrigerator, and be sure to label the jar. In late spring or early summer, plant your seeds in soil. Thin and replant once they grow a few inches high. Tomatoes Tomato plants often have issues with bacteria, so make sure you choose fruit from very healthy plants and allow the fruit to ripen completely before harvesting the seeds. Once ripe, scoop out the seeds along with the gel that surrounds it. Place the seeds into a jar with some water. Stir the mixture twice each day until the mixture ferments. Around day five, the seeds will sink to the bottom of the jar. When this happens, pour off the liquid, rinse the seeds and dry them spread out on paper towels or cloth. Store the same way as for peppers. Peas and beans Again, this is a situation of harvesting the seed for your next harvest , saving you the cost of purchasing new seeds or plants. Wait until peas or beans are very dry and turn brown on the plant before harvesting. You should hear the seeds rattle inside the pod. After removing the entire pod from the plant, lay it to dry for at least two weeks. At this point, you can remove the seeds or leave the entire pod intact and remove the seeds when planting season arrives. Potatoes Some argue that potatoes need to be grown from potato starts specific to the purpose. However, any backyard gardener knows that if left alone for an extra week, those potatoes in the drawer will sprout voluntarily. To grow your own potatoes, cut your sprouting potatoes into large chunks, about two inches around, and leave them to dry out for a few days. In early spring, drop the chunks into the soil for harvest in mid-summer. Barrels or large pots work well for creating layers of potatoes in a compact space.

You may not have even realized that the little seeds on the outside of the berry can produce more plants. To harvest the seeds, use tweezers. Alternately, you can “peel” the outer layer off the strawberry. Place the peel or seeds in soil and cover lightly with more soil. Place in a sunny windowsill and water regularly until the starts emerge from the dirt and are ready for transplanting outdoors. Turmeric You may have heard how easy it is to grow your own ginger, so it’s not surprising the turmeric will grow using the same technique. As rhizomes, the large bulbs divide and regenerate well. The trick is to plant the root sideways, which may feel contrary to what you’re used to. Turmeric naturally grows best in tropical locations, so it will probably perform best indoors across most of the United States; it will be happiest at 75-80 degrees. Plant the root in soil, water frequently and allow it a few months to mature. Harvest when it begins to dry out. Pumpkins If you’ve ever thrown a pumpkin into a  compost  pile, you’ve probably seen a plant shoot out of the ground some months later. Grow your own pumpkins (on purpose) by drying a few seeds from last year’s jack-o-lantern. Create a dirt mound in your garden and plant the seeds well spaced apart, or thin the plants once they pop through the soil. Pineapples When you think pineapple, you probably envision tall, swaying palm trees and tropical breezes, but it is possible to turn one pineapple into another in the comfort of your home. Cut the top off of a healthy pineapple and prop it above a container filled with water. You want it to hover rather than float — toothpicks can help with this. Keep the water level consistent until you see roots begin to form. At this point, transplant your pineapple into potting soil. Fruit trees It does take a long-term commitment, but apple, nectarine, peach, plum, apricot, cherry and even lemon trees will grow from seed. Simply save seeds from healthy, non-hybrid fruits. Dry them thoroughly, and plant them in quality soil in an area that receives direct sunlight. For the best results, plant a few of each type of tree next to each other.

Climate change to change the color of the oceans over the next 80 years

Comments Off on Climate change to change the color of the oceans over the next 80 years

The color of the oceans is about to undergo some major changes. As a result of ongoing climate change , scientists are predicting that the color of the oceans will slowly become bluer over the next 80 years. The color difference is directly connected to microbial phytoplankton , which absorb sunlight near the surface of the ocean. As the acidity and temperature of the oceans rise, the number of phytoplankton is expected to decrease in certain regions. Once the phytoplankton populations drop off, the surface will have a harder time reflecting sunlight, which will ultimately change its color. Related: Oceans warming 40 percent faster than previously thought According to Gizmodo , new research from Nature Communications argues that the subtropical oceans will be most affected by the color change. These regions are particularly susceptible to temperature and pH fluctuations, which will harm phytoplankton populations. Conversely, oceans in the Antarctic and Arctic could become greener, because these areas are not likely to experience significant changes in water temperature. Scientists have been using satellites to monitor the color of the oceans over the past 20 years. The images taken by the satellites are manipulated by a computer algorithm, resulting in a rough sketch of how much chlorophyll is present in the water. The only issue with this tactic is that climate change is not the only force at work here. Natural forces, like El Niño , also affect the color of the oceans. This is why scientists are exploring other methods of detection that will isolate the impacts of climate change. This includes measuring food sources for phytoplankton, looking at patterns of ocean circulation and analyzing growth rates of phytoplankton populations around the world. “Our model can now suggest what such satellites might see in the future world,” MIT scientist Stephanie Dutkiewicz explained. Experts predict that by 2100, the temperature of the oceans will have risen by at least 3 degrees Celsius. This difference in temperature is expected to change the color of around half of Earth’s oceans, though the color difference will not be detectable by human sight. Via Gizmodo Image via NOAA

Prosecco production is destroying soil in some Italian vineyards

Comments Off on Prosecco production is destroying soil in some Italian vineyards

Many people enjoy a glass of prosecco with their dinner , because it pairs well with everything from seafood to spicy Asian dishes. But the demand for the Italian sparkling wine is starting to cause some problems. According to a new study released earlier this month, the wine is destroying the soil in northeastern Italy’s vineyards. The amount of soil erosion from Italy’s prosecco vineyards is not sustainable, according to Jesus Rodrigo Comino, a geographer at the Institute of Geomorphology and Soils in Malaga, Spain. Even though he wasn’t involved in the study, he said that the future of the vineyards could be in jeopardy. Italy’s prosecco vineyards produce about 90 million bottles of the sparkling wine each year. After growing concerns about the skyrocketing demand of prosecco and its effect on the local environment, researchers from the University of Padua in Italy decided to look into the “soil footprint” of high-quality prosecco. Related: The growing wine industry is threatening California’s Napa Valley After studying 10 years of data for rainfall, land use, soil  and topographic maps, they found that prosecco was responsible for three-quarters of total soil erosion in the region. Then, they compared the soil erosion numbers with annual prosecco sales and came up with an annual “soil footprint” of 4.4 kilograms per bottle. It is worth noting that soil erosion isn’t always negative. To keep an ecosystem healthy, the erosion can help generate new soils. But that doesn’t mean that this current trend with prosecco production should continue. Scientists said that vineyard owners can reduce soil loss by leaving grass between the rows. According to simulations, this one solution could reduce total erosion by half. Other ideas include planting hedges and other greenery around the vineyards and also by the rivers and streams. According to Comino, “Only the application of nature-based solutions will be able to reduce or solve the problem.” Via Science News Image via seogolic0
