The Decomposer Shelf-Life Challenge Quiz

Discover essential facts about waste decomposers used in organic farming, their roles, benefits, and best practices. Perfect for those looking to improve soil health and sustainable agriculture knowledge.

1. Role of Waste Decomposers

   What is the primary role of waste decomposer microbes in organic farming systems?

   1. They directly increase crop yield by producing plant hormones.
   2. They neutralize all soil acidity regardless of the starting pH.
   3. They control insect pests by repelling them.
   4. They accelerate the breakdown of organic matter into nutrient-rich compost.

   Explanation: Waste decomposer microbes help decompose organic waste, turning it into valuable compost that enriches the soil. They do not directly increase yield by producing hormones, although soil fertility can support growth. They don't control pests or universally neutralize soil acidity; those are different processes or require additional input.

2. Composition of Waste Decomposer Solutions

   Which of the following ingredients is commonly included when preparing waste decomposer solutions for use in the field?

   1. Jaggery
   2. Diesel
   3. Synthetic fertilizer
   4. Stone chips

   Explanation: Jaggery provides a sugar source that supports the growth and multiplication of beneficial microbes in the decomposer solution. Synthetic fertilizer, diesel, and stone chips do not support microbial growth and are not appropriate in decomposer preparation.

3. Application Frequency

   How often should a waste decomposer solution typically be applied to compost piles or organic waste in small-scale farming?

   1. Three times daily
   2. Once every one to two weeks
   3. Only at the time of harvest
   4. Once per year

   Explanation: Regular application, such as once every one to two weeks, helps maintain active microbial populations for effective decomposition. Applying three times daily is excessive, only at harvest is too late, and once per year is insufficient for continuous composting.

4. Shelf Life and Storage

   What is the recommended shelf life of a properly prepared waste decomposer solution when stored in a cool, shaded place?

   1. Up to 30 days
   2. Indefinitely, with no change in quality
   3. 6 hours
   4. Only 2 days

   Explanation: A decomposer solution can typically be used for up to 30 days if stored properly. Beyond this, microbial activity may diminish. Two days or six hours underestimates its stability, and it cannot remain unchanged indefinitely.

5. Benefits for Soil Health

   What is a key benefit of regularly using waste decomposer in organic farming soils?

   1. Prevents rainfall from reaching the ground
   2. Removes all essential minerals from soil
   3. Makes the soil completely sterile
   4. Increases soil microbial diversity and improves nutrient cycling

   Explanation: Decomposer use introduces beneficial microbes, enhancing soil life and the breakdown of organic material. Sterilizing, blocking rain, or stripping minerals are not effects of waste decomposer application.
