What Materials Should And Should Not Be Screened In The Composting Process?

Do you know what should and should go into your compost? By screening materials that you do not qualify, you will have the best ingredients for your compost pile.

The materials that make up compost are raw and they typically come from waste. These organic disposable materials can come from a variety of places in and around your home. They can also come from your garden or your home. The more organic waste that is used for composting, the less of it that ends up in landfills.

Recent studies done by the EPA have shown that over 20 percent of the country’s solid waste system consists of food scraps and yard trimmings. This results in plenty of waste that ends up in landfills when the more eco-friendly alternative would be to compost it instead.

The Advantages Of Composting

One of the best reasons to compost is that you will know what is going into your composting material, and you can keep the things that you do not want out. You have the ability to balance the compost to your specifications, and you do not have to rely on just one component.

Instead, you can choose a range of ingredients for your pile. These ingredients are usually divided into green and brown materials. The more variety you use when choosing the materials, the more nutrient rich the compost will be. It will be filled with diverse microbial life and micro nutrients that are necessary in the composting process.

Ingredients To Include

The following is a small list of things that you should use for composting material. They include:

Grass clippings
Leaves
Coffee grounds
Dry dog food
Lint from dryer
Organic manure
Wine
Dust

There are some items that you can include in your compost, but it is important to know that these materials may need additional prep time before they are ready. You can mix them in with your composting materials, or you can place them in a pile in your backyard.

However, be aware that it may take several seasons before they are suitable for composting. These items include:

Newspaper
Paper bags
Toothpicks
Egg cartons
Saw dust
Pine cones
Corn cobs

Items To Screen

There are some materials that should be avoided when composting, and there are other materials that are definite no’s in the composting process.

The items that should be avoided include materials such as twigs and large branches.

Animal products and excrement should never be included in compost by compost windrow turner. Materials such as:

Animal droppings
Fish skin
Fish bones
Animal bones
Milk
Cheese

How To Increase Composting Time

Compost will begin to ‘cook’ once temperatures reach 120 degrees F, and there are several tips that you can follow to speed up this process.

After screening the unwanted materials, shred the larger materials for your compost. This allows bacteria to break it down faster.

It is better to add large piles of materials into your compost at one time.

Finally, always make sure your compost is in the sunlight.

Composting is a great way to increase the health of your garden, while also saving the environment. To keep your compost pile organic, screen for unqualified materials such as animal waste, animal products and synthetic chemicals.

How To Turn Cow Dung Into Powder Fertilizer?

Everywhere there are cows, you can always be sure of one thing, there will also always cow manure. As beef and dairy farming intensified, industrialized and specialized, the need to find urgent solutions for cow dung environmental pollution problems became real. As a result, many machines were inverted to turn cow dung into powder fertilizer.

Let’s consider the fact than an average beef cattle unit produces around 10.5 tons of manure annually, and an average dairy cow unit produces more than 15.4 tons of manure annually. To put things into perspective, a city with 410,000 residents produces less waste than a single dairy farm consisting of 2,500 animals. Cow dung pollution is a huge global problem. In some countries, pollution from cattle manure exceeds industrial pollution. Many people wrongly believe that animal waste is “natural” so it’s not dangerous, but that is not the case.

Fortunately, cow dung can be converted into an excellent organic fertilizer powder. It contains all the nutrients plants need to thrive and it’s rich in organic matter. The NPK profile of cow dung is 1% potassium, 4% nitrogen, and 2% phosphorous. The other constitutes of cow dung besides micronutrients and organic matter are various enzymes and microorganisms. In order to convert cow dung into fertilizer powder, specialized machines are often needed. The fertilizer produced can vastly improve soil structure and fertility. What’s more, the fertilizer can promote healthy microbial growth and prevent common root diseases and rot.

Cow manure is a good organic fertilizer, but if you put fresh cow dung onto the soil, the vast amounts of ammonia produced can cause a horrible odor and burn crops. In addition, unprocessed cow dung can be high in salt, depending on the diet the cattle were fed, which is not ideal for crop growth. To create a nutritious fertilizer, cow dung must be composed. Natural fermentation of cow dung can take a long time, but fortunately, there is now a range of modern composting machinery in the marketplace designed to speed up the process.

Cow dung must be fully fermented before it is applied to agricultural soil. Otherwise, it will cause soil temperatures to increase, which can damage crop root systems. Furthermore, fresh cow dung is full of harmful bacteria and pathogens, which can be damaging to the surrounding environment and water supplies.

To turn cow manure into a safe organic NPK powder fertilizer, it must be fully decomposed. The best way to compost cattle waste is to invest in the best cow dung fertilizer machines, like self-propelled compost turners, hydraulic windrow turners, and dewatering machines.

High-grade NPK compound fertilizer is in high demand and it is relatively cheap to produce. By producing powder fertilizer from cow dung, you can help to deal with the mounting global environmental pollution problems associated with mounting animal waste. What’s more, with the right equipment, powder fertilizer can be processed further into granules or pellets. Granules are easier to store and transport.
