22 JulSOIL-Sifat Perilaku




Pertanyaan:  Mengapa?!


Dalam praktek (in practices):

  • Hewan dan tumbuhan tidak dapat menjawab pertanyaan mengapa (why)?!.
  • Karena itu perlu diketahui sifat dan perilaku (fate and properties ~ nature and properties) mereka.
  • Juga perlu diketahui syarat pertumbuhan dan kehidupan mereka.
  • Bila ada masalah, perlu diketahui alternatif solusi.
  • Tindakan ini adalah kunci pengelolaan (management) dalam memperoleh teknologi inovasi.


Contoh:  teknologi pengomposan oleh cacing tanah (earthworm composting):


Worms are easy to grow. They’re basically vegetarians and like to eat the vegetable wastes from your kitchen, yard and garden. Worms don’t eat inorganic materials, like plastic, glass or metals. Worms prefer relatively fresh, hard foods like apples, carrots and other fresh vegetables until they have begun to decompose slightly. If you feed your worms these kinds of foods, don’t be concerned if it takes the food some time to disappear. It’s all part of worm composting process. It does help to break or cut up hard foods in a food processor, bit it isn’t required.

Worms don’t have teeth, but do have mouths. They take food in through their mouths and then digest it in their gizzards. A worm’s gizzard needs a small amount of grit (from soil) to grind food. That’s why it’s important to add a handful of garden soil to the bedding material in your bin.

Numerous variables affect how much your worms will eat. For example, they are more active at room temperature than at 40°F. A general rule is that they will consume approximately ½ their body weight in food waste per day, so if you purchased 1 lb. of worms, you can expect them to consume about ½ lb. of vegetable waste per day.

Overfeeding your worms can cause odor problems. If you over-feed your worms, just stop feeding them and allow the worms to catch up. As the worm population increases, you should gradually add more food to the bin.
