Compost & Organic Fertiliser Pelletising Technology
A wide variety of soils today are producing less and costing more to manage. Farmers and growers are continually frustrated with the problems of declining soil structure, apparent nutrient tie up, and decreasing crop yields. By applying organic fertilisers in pelletised form farmers are providing the catalyst for promoting healthy growth by stimulating the natural processes that occur in the soil. Both soil conditioning and fertilising benefits result from their use. The physical effects of organic pelletised organic fertilisers on the soil are perhaps more important than the direct fertiliser effects. Poor soil structure inhibits root growth, reducing the ability of a plant to reach much needed nutrients.
Adding organic pellets within the root zone, promotes the aggregation of soil particles, so that structure and tilth is significantly improved. Roots, air and water can move easily through the soil. In sandy soils, organic matter holds both water and nutrients, making them available for plant growth, and minimising leaching.
Benefits can include:
• Unlocking ‘tied up’ nutrients
• Controlling nutrient release
• Retain moisture and nutrients
• Excellent source of organic matter
• Acts as a pH buffer
• Improves soil structure
• Encourages earthworm and soil microbial activity
• Reduces leaching
• Increased yields
• Increased resistance to pests
• Increased root development
• Increased protein levels
• Introduces a full balanced range of nutrients
For years compost and organic fertiliser producers have been struggling to successfully create pellets with traditional pelletising technology. Organic fertilisers however require precise temperature and pressure management during the pelletising operation. Rotary presses cause high temperatures which kill the beneficial microorganisms necessary for healthy soil. Through meticulous research and development, Compost Matters has created the most effective and efficient organic fertiliser pelletiser. The solution is the Compost Matters J300 pellet press. Using our unique vertical press design and pressure control, pellets are produced at below 40 deg C, ensuring healthy organic fertilisers, ideal for use with standard vacuum planters, ploughing, tilling or broad acre broadcast methods. Pellets also provide higher concentrations of material thus reducing application rates compared to conventional organic fertilisers. The bulk density of the pellets are higher (approx 850kg/m3 compared to bulk compost of 500kg/m3) allowing more compost to be freighted per unit volume.
We specialise in supplying robust industry proven pelletising equipment, supplies and full production plant layout and construction.
We supply kit based starter pelletisers for on farm and small volume (<8t per day) production, through to high volume production plants producing (100t + per day). Our high quality dies are long lasting and provide over 500t production per die at less than $1/tonne cost. Pelleted compost has several practical advantages over bulk compost:
- The bulk density of the pellets are higher (approx 850kg/m3 compared to bulk compost of 500kg/m3 ) allowing more compost to be freighted per unit volume. This increases the distances compost can be freighted economically.
- The application rates in broad-acre systems drop from up to 90% of regular bulk compost broadcast per hectare, and pelletised compost placed precisely at seeding at rates of 50kg – 100kg per hextare.
- The compost is applied using existing sowing machinery at seeding, which also eliminates the separate spreading operation required with bulk compost. It places the compost pellet under the soil surface next to the seed for more immediate effect (compost pellets could also be applied using conventional broadcasting machinery).
The Compost Matters J300 is used to create pellets from almost any screened organic material. Optimal pellet binding is ensured by controlling the raw material moisture levels to between 15%-30%. Some customers also create blends through the addition of certain trace elements such as lime or phosphate.
We have recognised the need for versatility and agility in pellet production and have designed the J300 pelletiser plant to consist of 3 pre-assembled turn-key components. The kit can be configured to fit in to most operational areas. Each of the components can be used in isolation or in combination with the other, and can be lifted and moved to another facility without requiring new equipment. Feed intake control is calibrated on the conveyer system to allow seamless operation with minimal human intervention. Increasing capacity or additional components such as blending or bagging is also easily integrated. The average output volume for the single press kit is 800kg – 1000kg per hour using composted organic material.
