It | | | | requires the | | | | introduction of | | | | oxygen to the | | | | compost pile to | | | | allow aerobic | | | | microbes to | | | | thrive. | | | | | | | | | | | | | | | | - **Agricultural | | | | Waste** - is | | | | unwanted or | | | | unsalable | | | | materials | | | | produced wholly | | | | from agricultural | | | | operations | | | | directly related | | | | to the growing of | | | | crops or raising | | | | of animals for | | | | the primary | | | | purpose of making | | | | a profit or for a | | | | livelihood. | | | | | | | | - **Anaerobic | | | | Composting** -- | | | | decomposes waste | | | | without oxygen. | | | | Organic materials | | | | are piled up and | | | | breakdown | | | | naturally. This | | | | process does not | | | | need any type of | | | | maintenance and | | | | do not need to be | | | | turned. | | | | | | | | - **Compost** -- is | | | | used to improve | | | | the soil | | | | fertility in | | | | gardens, | | | | landscaping, | | | | horticulture, | | | | agriculture and | | | | organic farming. | | | | | | | | - | | | | | | | | [[https://www.slidesh | | | | are.net/slideshow/s]{ | | | |.underline}](https:// | | | | www.slideshare.net/sl | | | | ideshow/solid-waste-m | | | | anagement-77400312/77 | | | | 400312) | | | | | | | | - **Waste** - is | | | | any substance | | | | which is | | | | discarded after | | | | primary use or in | | | | other words, | | | | there is no | | | | further use for | | | | the product. We | | | | generate a huge | | | | amount of wastes | | | | in our everyday | | | | life. | | | | | | | | - **Waste | | | | Management** - | | | | refers to the | | | | various ways of | | | | managing and | | | | disposing of | | | | wastes. It can be | | | | by discarding, | | | | destroying, | | | | processing, | | | | recycling, | | | | reusing, or | | | | controlling | | | | wastes. | | | | | | | | - **Waste | | | | Processing** -- | | | | is a way of | | | | applying | | | | operations using | | | | facilities on how | | | | to change solid | | | | wastes into | | | | chemical, | | | | physical, or | | | | biological | | | | properties to | | | | make it easier to | | | | dispose of, | | | | recover a | | | | resource, or | | | | transfer solid | | | | waste materials. | | +-----------------------+-----------------------+-----------------------+ +-----------------------+-----------------------+-----------------------+ | | 1. | | | | | | | | | | | | | | | | 2. | | | | | | | | | | | | | | | | 1. **Production** - | | | | is the function | | | | of the amount and | | | | nature of | | | | agricultural | | | | waste generated | | | | by an | | | | agricultural | | | | enterprise. The | | | | waste requires | | | | management if the | | | | quantity produced | | | | is sufficient | | | | enough to become | | | | a resource | | | | concern. A | | | | complete analysis | | | | of production | | | | includes the | | | | kind, | | | | consistency, | | | | volume, location, | | | | and timing of the | | | | waste produced. | | | | | | | | 2. **Collection** - | | | | refers to the | | | | initial capture | | | | and gathering of | | | | the waste from | | | | the point of | | | | origin or | | | | deposition to a | | | | collection point. | | | | The method of | | | | collection, | | | | location of the | | | | collection | | | | points, | | | | scheduling of the | | | | collection, labor | | | | requirements, | | | | necessary | | | | equipment or | | | | structural | | | | facilities, | | | | management and | | | | installation | | | | costs of the | | | | components, and | | | | the impact that | | | | collection has on | | | | the consistency | | | | of the waste | | | | should be | | | | identified. | | | | | | | | 3. **Transfer** - | | | | refers to the | | | | movement and | | | | transportation of | | | | the waste | | | | throughout the | | | | system. It | | | | includes the | | | | transfer of the | | | | waste from the | | | | collection point | | | | to the storage | | | | facility, to the | | | | treatment | | | | facility, and to | | | | the utilization | | | | site. | | | | | | | | 4. **Storage** - is | | | | the temporary | | | | containment of | | | | the waste. The | | | | storage facility | | | | of a waste | | | | management system | | | | is the tool that | | | | gives the manager | | | | control over the | | | | scheduling and | | | | timing of the | | | | system functions. | | | | | | | | 5. **Treatment** - | | | | is another | | | | function designed | | | | to reduce the | | | | pollution | | | | potential or | | | | modify the | | | | physical | | | | characteristics | | | | of the waste, | | | | such as moisture | | | | and total solid | | | | (TS) content, to | | | | facilitate more | | | | efficient and | | | | effective | | | | handling. Manure | | | | treatment is | | | | comprised of | | | | physical, | | | | biological, and | | | | chemical unit | | | | processes. It | | | | also includes | | | | activities that | | | | are sometimes | | | | considered | | | | pretreatment, | | | | such as the | | | | separation of | | | | solids. | | +-----------------------+-----------------------+-----------------------+ +-----------------------+-----------------------+-----------------------+ | | 3. | | | | | | | | | | | | | | | | 1. Any reaction from | | | | the videos we | | | | just watched a | | | | while ago? | | | | | | | | 2. | | | | | | | | | | | | | | | | 1. | | | | | | | | | | | | | | | | 2. | | | | | | | | | | | | | | | | 3. 1. **Liquid | | | | Waste** - is | | | | commonly | | | | found in | | | | households as | | | | well as in | | | | industries. | | | | This waste | | | | includes | | | | dirty water, | | | | organic | | | | liquids, wash | | | | water, waste | | | | detergents | | | | and even | | | | rainwater. | | | | | | | | 2. **Solid | | | | Rubbish** - | | | | Solid rubbish | | | | can include | | | | various items | | | | found in your | | | | household, | | | | along with | | | | commercial | | | | and | | | | industrial | | | | locations. | | | | Solid rubbish | | +-----------------------+-----------------------+-----------------------+ +-----------------------+-----------------------+-----------------------+ | | a. **Plastic waste** | | | | -- consists of | | | | plastic bags, | | | | containers, jars, | | | | bottles and other | | | | products that can | | | | be found at home. | | | | Plastic is not | | | | biodegradable, | | | | other types of | | | | plastic can be | | | | recycled. Take | | | | note that plastic | | | | should not be | | | | mixed in with | | | | your regular | | | | waste; it should | | | | be sorted and | | | | placed in your | | | | recycling bin. | | | | | | | | b. **Paper/card | | | | waste** -- | | | | includes | | | | packaging | | | | materials, old | | | | newspapers, used | | | | cardboard and | | | | other products. | | | | Paper can easily | | | | be recycled and | | | | reused, so place | | | | them in your | | | | recycling bin and | | | | think of the best | | | | way how you can | | | | use those as your | | | | materials in | | | | creating | | | | something | | | | saleable out of | | | | it. | | | | | | | | c. **Tins and | | | | metals** -- can | | | | be found in | | | | various forms | | | | throughout your | | | | home. Most metals | | | | can be recycled. | | | | It can be | | | | recycled and used | | | | in making some | | | | display materials | | | | at home like | | | | creating flower | | | | vase, small | | | | lampshade etc. | | | | | | | | d. **Ceramics and | | | | glass** -- These | | | | items can easily | | | | be recycled. Look | | | | for special glass | | | | and bottles and | | | | can create them | | | | into something | | | | useful like | | | | sugar, coffee, | | | | and cream | | | | containers. | | | | | | | | | | | | | | | | 3. **Organic | | | | Waste** - Organic | | | | waste is another | | | | common household. | | | | All food waste, | | | | garden waste, | | | | manure and rotten | | | | meat are | | | | classified as | | | | organic waste. | | | | Over time, | | | | organic waste is | | | | turned into | | | | manure by | | | | microorganisms. | | | | | | | | 4. **Recyclable | | | | Rubbish** - | | | | Recyclable | | | | rubbish includes | | | | all waste items | | | | that can be | | | | converted into | | | | products that can | | | | be used again. | | | | Solid items such | | | | as paper, metals, | | | | furniture and | | | | organic waste can | | | | all be recycled. | | | | | | | | 5. **Hazardous | | | | waste** includes | | | | all types of | | | | flammables, | | | | toxic, corrosive | | | | and reactive | | | | rubbish. It also | | | | includes | | | | radioactive waste | | | | and chemical | | | | wastes.

What are the materials needed in making fermented foliar fertilizer in school or at home? 2. How do we properly make fermented foliar fertilizer? 3. Why do we need to try making a fermented foliar fertilizer? 2. Worked Example ============== Materials needed in making a fermented foliar fertilizer ======================================================== - 1 ripe banana (lakatan) - 1 apple - few pieces of grapes (optional) - ¼ kilos or 250 grams brown sugar - 1 spoon for mixing the mixtures - Plastic container with cover - Clean chopping board - Knife Procedures in Making a Fermented Foliar Fertilizer ================================================== 4. Prepare all the needed ingredients, materials and tools in making a foliar fertilizer. +-----------------------+-----------------------+-----------------------+ | | 2. | | | | | | | | | | | | | | | | 3. Put in a clean | | | | plastic container | | | | the 1st mixture | | | | and add ¼ kilo or | | | | 250 grams of | | | | brown sugar. | | | | Combine 1st | | | | mixtures and | | | | sugar, must be | | | | 1:1 ratio, mix | | | | thoroughly, | | | | repeat mixing the | | | | 1st combined | | | | mixtures with | | | | sugar several | | | | times until it | | | | blends well. | | | | | | | | 4. Once the combined | | | | mixtures are | | | | already thickened | | | | and blends well. | | | | Seal it with a | | | | tightly closed | | | | container and do | | | | not forget to | | | | indicate the date | | | | when you actually | | | | prepared the | | | | sliced fruits and | | | | sugar, so that | | | | you will be able | | | | to determine when | | | | it will achieve 7 | | | | days or weeklong | | | | fermentation | | | | required days. | | | | | | | | 5. After 7 days of | | | | fermentation, you | | | | can now check if | | | | it resulted well | | | | and ready to be | | | | used as organic | | | | fertilizer to | | | | your flowering | | | | plants or other | | | | form of plants or | | | | crops. | | | | | | | | 6. To check, you | | | | open the | | | | container then, | | | | sift the juice | | | | that was formed | | | | from the | | | | fermented | | | | mixtures. | | | | | | | | 7. You can now make | | | | a mixture for | | | | spraying it on | | | | the plants (1 | | | | tsp. of fermented | | | | fruit juice | | | | foliar fertilizer | | | | plus 100ml. clean | | | | water. Then shake | | | | the mixture that | | | | was placed in a | | | | bottle sprayer. | | | | | | | | 8. You can now spray | | | | it on the plant, | | | | use it as an | | | | organic | | | | fertilizer that | | | | will help your | | | | plants develop | | | | and grow healthy. | | | | | | | | 9. Monitor and | | | | document if the | | | | plants you were | | | | able to apply | | | | foliar fertilizer | | | | developed and | | | | grow successfully | | | | (by taking | | | | pictures with | | | | corresponding | | | | dates on your | | | | recorded | | | | documentation as | | | | a proof). | | | | | | | | 10. Show and report | | | | to your teacher | | | | the results of | | | | your outputs | | | | through | | | | submitting your | | | | portfolio of | | | | documentation | | | | with narratives | | | | as your proofs | | | | for proper | | | | rating. | | +-----------------------+-----------------------+-----------------------+ +-----------------------+-----------------------+-----------------------+ | | 1. | | | | | | | | | | | | | | | | 2. | | +-----------------------+-----------------------+-----------------------+ +-----------------------+-----------------------+-----------------------+ | | 1.
