Shelf Life of Waste Decomposer Quiz Quiz

Explore key facts about the storage, effectiveness, and handling of waste decomposer in organic farming. Ideal for farmers, students, and anyone interested in sustainable agriculture.

1. Proper Storage Conditions

   What is the recommended way to store waste decomposer solution to maximize its shelf life before use?

   1. Under intense sunlight
   2. Near open flames
   3. In the freezer
   4. In a cool, dark place away from direct sunlight

   Explanation: Storing waste decomposer in a cool, dark place away from sunlight helps maintain microbial activity and prevents spoilage. Freezing can kill beneficial microbes, open flames are unsafe, and sunlight degrades quality and activity.

2. Shelf Life Duration

   When stored properly, what is the typical shelf life of a freshly prepared waste decomposer solution?

   1. 3 days
   2. 6 hours
   3. Up to 30 days
   4. 1 year

   Explanation: Properly stored waste decomposer can be effective for up to 30 days. Three days and 6 hours are too short, while one year is unrealistic because microbial viability decreases over long periods.

3. Visual Signs of Expiry

   Which sign indicates that a waste decomposer solution may have exceeded its shelf life?

   1. A foul or unpleasant odor
   2. Mild earthy aroma
   3. Consistent color and smell
   4. Slight bubbling

   Explanation: A foul or strange odor suggests spoilage or contamination. Slight bubbling, consistent color, and mild earthy aroma are normal signs of healthy waste decomposer.

4. Effect of Dilution on Shelf Life

   How does diluting waste decomposer with water before use affect its shelf life?

   1. It prolongs shelf life
   2. It preserves the microbes indefinitely
   3. It shortens shelf life and should be used immediately
   4. It has no effect on shelf life

   Explanation: Diluting waste decomposer solution with water decreases microbial stability, so it should be used right away. Prolonged storage after dilution leads to loss of effectiveness. Diluting does not preserve it.

5. Impact of Temperature on Viability

   What is the effect of exposing stored waste decomposer to high temperatures for an extended period?

   1. Effectiveness increases
   2. Microbial activity decreases, reducing effectiveness
   3. No change occurs
   4. Shelf life extends indefinitely

   Explanation: High temperatures harm the beneficial microbes, reducing their activity and thus shortening shelf life. Effectiveness does not increase, and shelf life is not extended by heat.
