我家后院前几任应该都是大树和花，我们打算种点儿果树和蔬菜。我有点担心，怕以前长期使用过杀虫剂除草剂之类的，想先测一下土壤成分。如果土壤有问题，蔬菜就用raised bed，不直接种地里。在Amazon上看到的soil test kit都是测酸碱度，阳光养分什么的，没看见提到农药之类的有害成分。大家有人测过的吗？讲讲吧，谢谢！
Here’s How To Test Your Soil Using a spade or trowel, take small samples of soil from three to ten random spots in your garden. The Environmental Sciences Analytical Center at Brooklyn College recommends sampling 6 to 8 inches deep for vegetables. Thoroughly mix the soil in the container, taking care to remove any pebbles, leaves, or roots you might find. Then, transfer at least one cup of the soil mixture into a plastic bag and seal it (don’t fill the bag; it’ll be flattened if you mail it in an envelope and you don’t want dirt spilling out). Make sure the sample is dry; do not dry soil on a stove or radiator as this may affect the readings. Mail the bag to your preferred testing site. Many of the colleges and universities who operate soil testing programs offer testing services at a low cost (most tests cost between $10-20: be sure to ask for heavy metal testing in addition to the standard panel). If you live in the East or South, try the University of Delaware College of Agriculture and Natural Resources. Folks in the Midwest should try Midwest Laboratories (a nationally-renowned testing center), or the K-State Soil Testing Lab at Kansas State University. West-Coasters should check out Perry Laboratory and Wallace Laboratory, two California-based greats who work specifically with farmers and gardeners. New Englanders need look no further than the University of Massachusetts, Amherst Soil and Plant Tissue Testing Laboratory, which boasts a 3-6 day turnaround time for most samples. Follow-up with whoever conducts your soil test on how to proceed with your gardening plans. This video from the University of Delaware’s Soil Testing Program offers a nice introduction on how to decipher the numbers that will come back with your results.

哈哈，谢谢！
蔬菜就用raise bed 买土，果树这个大概没什么好办法。
