Problem: Article: There are thousands of different types of soybeans. If you want to eat your soybeans, make sure you have an edible, green variety. If you want to make soy milk or flour, find a yellow-seeded variety. If you are planning on drying the soybeans, get a black-seeded variety. Choosing the right soil for your soy plants has many advantages, including that there will be fewer weeds, less erosion, and the right balance of nutrients and pH in the soil. This will produce healthier plants with better yields.  The best type of soil for soybeans is well-draining loam that isn't packed too tightly.  If you're working with soil that has a high clay content, you can make it more suitable for growing soy by mixing it with peat moss, sand, or mulch. Soybean plants will generally produce the highest yields when the beans are planted in May, but the soil temperature is something you have to take into consideration as well. The ideal time to plan soybeans is two to three weeks after the last frost, when the soil warms to about 60 F (15.5 C) and the air to about 70 F (21 C). Soy plants need a good balance of nutrients in the soil to grow properly. If there are too many or too few nutrients, the plants won’t grow properly. Therefore, it’s important to add a fertilizer to the soil if the area hasn’t been enriched in recent years. For soil that hasn’t been enriched recently, add aged manure or compost to the soil to add more nutrients to the seedbed before planting. One particular nutrient that soy plants require a lot of is nitrogen. The best way to ensure that they get what they need is to inoculate the beans with Bradyrhizobium  japonicum, which is a nitrogen-fixing soil bacterium.  To inoculate the beans, place the beans in a bucket and sprinkle them with the bacterium. Use a spade or small shovel to mix the beans and coat each one. Keep the seeds out of direct sunlight and plant them within 24 hours of inoculation. You can purchase Bradyrhizobium japonicum through catalogues, online, or in some gardening and farm supply stores. Sow the soybeans 1.5 inches (3.8 cm) deep into the soil, and space the beans about 3 inches (7.6 cm) apart. Plant the beans in rows that are about 30 inches (76 cm) apart. Water the beans once they’ve been planted, but only until the soil is moist. Do not overwater newly planted beans, otherwise they may crack.
Summary: Select the right type of seeds. Pick the right soil. Plant at the right time. Prepare the seedbed. Inoculate the seed. Plant the seeds.

Problem: Article: When you have rolled your bread slices up, you should have one or more burrito shaped rolls. In order to make them into pinwheel sandwiches, take a knife and hew them into evenly-sized chunks. Cut them into bite-sized chunks that are similar in size to bites of sushi. If you want a proper measurement, cut the pieces in one inch segments. An inch length is a good bite-size for this type of sandwich. If you've sufficiently loaded your sandwiches, there's a good chance there will be ingredients that are protruding from the bread once you've rolled it up. If there's anything sticking out from your roll, snip it off as close to the roll as you can. If you're short and time and aren't trying to make perfect pinwheels, you don't necessarily have to trim the excess pieces. But doing so will make your pinwheels look more professional. Although pinwheel sandwiches do a reasonably good job of holding their shape, locking them down with a toothpick will make sure they don't unfurl before being eaten. Before you present them, impale them down the centre with one toothpick each. If you're packing the sandwiches for children, it may be best for safety's sake to go without the toothpicks. The same applies to serving the very elderly. Pinwheel sandwiches are a perfect party food. Because they look great as a finger food, you should put some effort into the way you present them on a platter. The most common way to do this is to ring them around the perimeter of the platter, working your way in as you fill the tray. Including a dipping sauce in the center of the platter will be a hit if you're serving a group. Pinwheel sandwiches are small enough to fit snugly into a kid's lunch box. Seal them in ziploc bags to preserve their freshness. Because of their small size, you should be able to pack three or four into one bag. If you're making them specifically for a child, you should fill them with his favourite ingredients.
Summary:
Cut each roll into bite-size pieces. Slice off excess pieces. Secure your pinwheel pieces with a toothpick. Serve on a party platter. Pack in school lunches.
