{ "item_title" : "Vermiculture", "item_author" : [" Donald Connelly "], "item_description" : "Vermiculture means: cultivation of worms. It is possible because of the special characteristic of the worms. Worms contain both testes and ovaries as sex organs. Which means that worms are both male and female. So that every worm can exchange sperms by overlapping the other worm and then lay eggs. This way their population rate increases automatically. Once they come out of an egg, it takes approximately a year to form a full size worm. Their population rate depends on many factors, such as the available quantity of food, moisture in the soil, PH of soil, salts available in the soil, the capacity of reproducing and dispersing of the worms and temperature of the soil etc.", "item_img_path" : "https://covers4.booksamillion.com/covers/bam/1/30/096/941/1300969415_b.jpg", "price_data" : { "retail_price" : "17.48", "online_price" : "17.48", "our_price" : "17.48", "club_price" : "17.48", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
