How to Make My Own Fertilizer from Farm Waste – A Step-by-Step Guide for Farmers & Gardeners​

Have you ever looked at piles of manure, straw, or leftover crop residues on your farm and thought, Can I make my own fertilizer from farm waste? The answer is a resounding yes​ — and doing so can cut your input costs, improve soil health, and keep waste out of landfills. In this post, we’ll explore exactly how to make my own fertilizer​ using materials you already have, outline the essential equipment, and share practical tips to get started.

Why Make My Own Fertilizer?

There are three compelling reasons to make my own fertilizer:

Cost Savings​ – Commercial fertilizers can be expensive and subject to price swings. Farm waste is free, and once you invest in basic equipment, your ongoing costs drop dramatically.
Soil Health​ – Homemade fertilizer contains not just NPK but also organic matter and beneficial microbes that improve soil structure, water retention, and long-term fertility.
Environmental Impact​ – Turning waste into fertilizer reduces methane emissions from decomposing manure and prevents nutrient runoff from open dumping.
If you’ve been asking can I make my own fertilizer from farm waste?, you’ll find the process simpler than you think.

What Farm Waste Can You Use?

Nearly all organic farm by-products are suitable for make my own fertilizer:
Livestock manure​ (cow, pig, chicken): High in nitrogen and microbial life. Fresh manure is 50–80% water and must be treated before use.
Crop straw​ (corn stalks, rice husks, wheat bran): Supplies carbon and fiber, helping balance the carbon-to-nitrogen ratio.
Biogas residue or slurry: Nutrient-rich remains from anaerobic digestion, usually low in weed seeds and pathogens.
Spent mushroom substrate: Contains protein-rich fungal mycelium, boosting biological activity in the final product.
By blending these materials, you can tailor your make my own fertilizer​ recipe to the needs of your crops.

How can you change it 

Crawler compost turner is an advanced compost turning equipment, specially designed for compost fermentation process, with the advantages of high efficiency, stability, easy operation and so on.

Crawler compost tumbler realizes automatic operation through crawler walking system, which is the necessary equipment for producing organic fertilizer granules and widely used in organic fertilizer production line.

Also, you can have the fermentation tank to ferment your materials to convenient them to release their nutrition.

After your raw materials have fermented well, you can use a crusher to crush them, turning the product into a state suitable for mixing. This will facilitate the subsequent granulation process，so you can buy a crusher and a granulator. The granulator is the most key machine in your fertilizer production.

There are also many types of granulators, New type organic fertilizer granulator, also known as churning teeth granulator, is a kind of high-efficiency molding equipment, simple principle, fast granulation speed. 

At this step,your granulation is already well, if you have high quality demand and you want to store it for a long time,then you can put in a cooler and dryer,and also a screener to classify your products and to check whether them are up to standard.

The whole procedure machines needed

Organic fertilizer production line is a combination of a series of organic material raw material processing equipment for producing granular fertilizers that are easy to pack, transport and store for a long time.

Organic fertilizer production line mainly contains turner, raw material crusher, raw material mixer, granulator, drying and cooling system, screening machine and packaging machine and other equipment, according to the production needs of the increase or decrease in the machinery, in order to achieve the final production goals.

Raw materials commonly used in organic fertilizer production line listing above,

Animal waste: chicken dung, cow dung, horse dung, sheep dung, animal hair, etc.

Agricultural waste: plant straw (corn stalks, wheat straw, etc.), rice husk, rice straw, grass ash, etc.

Industrial waste: medicine residue, sugar residue, soybean meal, cotton meal, cassava residue, wine lees, oil residue, etc.

Municipal waste: sludge, kitchen waste and so on.

The above organic raw materials can be manufactured through a series of organic fertilizer processing, not only to reduce the harm caused by the accumulation of such harmful substances, but also to turn waste into treasure and environmental protection, is a new trend in agricultural development.

As you can see , many raw materials you can have in your house and daily you will waste them, now you can have a better idea to change them into fertilizers.

Key Benefits of Making Your Own Fertilizer

Cost Reduction: Up to 50–70% less than buying commercial fertilizer.
Customizable Nutrition: Adjust recipes for specific crops and soil tests.
Improved Soil Biology: More organic matter and beneficial microbes.
Waste Diversion: Less methane from decomposing manure, less landfill use.
Supply Security: No dependency on external suppliers, protecting against shortages.

FAQ 

Q1: Can I make my own fertilizer from all types of farm waste?​

Most organic farm waste works, but avoid highly saline straw or materials contaminated with heavy metals. Fresh manure must be fermented first to prevent root burn.

Q2: Do I need professional equipment to make my own fertilizer?​

Small-scale operations can start with basic tools (shovels, buckets, manual crushers). For consistent quality and larger volumes, invest in purpose-built machines like a Ferment Tank or crusher.

Q3: How do I control bad smells during fermentation?​

Ensure proper moisture (50–60%), add carbon-rich material (straw, husks) to balance C/N ratio (25:1), and cover piles or use sealed tanks to trap odors.

Q4: Will my homemade fertilizer match commercial nutrient levels?​

Yes. By supplementing with mineral sources (rock phosphate, potassium sulfate), you can reach or exceed commercial NPK values.

Q5: Why do my homemade granules crumble?​

Likely too little moisture or binder in granulation. Increase water or binder slightly (5–10%), and check machine speed if using a granulator.


Start small, test recipes on a patch of land, and as you refine your process, scale up with better equipment. In doing so, you’ll enjoy healthier crops, lower costs, and a cleaner, more sustainable farm.
