Why Adopt Conservation Tillage for Sustainable Farming?


Tillage plays a vital role in weed management by controlling the growth and spread of weeds in agricultural fields. By using tillage practices such as ploughing, discing, or harrowing, farmers can break up the soil and disrupt the root systems of weeds, making it more difficult for them to establish and compete with crops. 

Additionally, tillage can bury weed seeds deep enough in the soil that they are unable to germinate and grow. However, deep or over-tillage can also have adverse effects, such as soil erosion and the destruction of soil structure. Therefore, farmers must adopt conservation or minimum tillage practices to manage weeds while effectively preserving soil health.

In this blog, we’ll explore conservation tillage, its types, advantages and the equipment used for conservation tillage. You’ll learn how the Kelly Tillage System can help manage residue and weeds, incorporate fertiliser, or create the ultimate seedbed for optimal crops. 

What Is Conservation Tillage? Definition 

Conservation tillage is a farming practice that reduces soil erosion and improves soil health by minimising soil disturbance during tillage. Unlike traditional tillage practices, which involve ploughing and turning over the soil, conservation tillage techniques leave the majority of the soil surface undisturbed. 

By leaving crop residue on the soil surface, conservation tillage helps to protect against soil erosion by reducing the impact of raindrops and preserving the soil structure. It also helps maintain soil moisture levels, improves soil fertility, and reduces the amount spent on fuel and energy required for tillage. 

As a result, conservation tillage is best for farmers in Australia as a sustainable and efficient method of seedbed preparation. 

Let’s have a look at its types:

Types Of Conservation Tillage

There are several types of conservation tillage, including:


This is the most extreme form of conservation tillage, in which the soil is left undisturbed, and seeds are planted directly into the soil without any prior tillage. It helps to reduce soil erosion, conserve soil moisture, and maintain soil structure.

Reduced Tillage

Reduced tillage involves minimal soil disturbance, typically only enough to create a suitable seedbed for planting. This can include practices like strip-till, which only tills narrow strips of soil where seeds will be planted, or zone-till, which creates a shallow tilled zone in the soil where seeds will be placed.

Mulch Tillage

Mulch tillage involves leaving crop residues on the soil surface to act as a natural mulch, which can help to protect against erosion, conserve moisture, and improve soil health. It can be combined with reduced tillage to create a sustainable seedbed.

Ridge Tillage

Ridge tillage involves creating ridges of soil where seeds will be planted, while leaving the furrows between the ridges untilled. This can help to improve drainage and soil aeration while still providing a suitable seedbed for planting.

Contour tillage

 Contour tillage involves tilling along the contour of the land rather than up and down slopes. This can help to reduce erosion and improve soil structure on sloping land.

Conservation or minimum tillage practices aim to reduce soil erosion, maintain soil health, and increase sustainability in agriculture. The choice of tillage equipment for conservation tillage will depend on various factors, including soil type, crop rotation, and farm management practices.

Equipment Used for Conservation Tillage 

Several types of equipment can be used for conservation tillage, including:

No-till Drill

 A no-till drill is a specialised planter designed to plant seeds directly into the soil without prior tillage. This equipment can be used to plant crops like corn, soybeans, and wheat and is commonly used in conservation tillage systems.

Strip-till Equipment

This equipment is designed to till narrow strips of soil in the field, leaving the rest of the soil undisturbed. This helps reduce soil erosion while providing a suitable seedbed for planting.

Chisel Plough

 A chisel plough is a type of tillage equipment designed to break up compacted soil without completely overturning it. This equipment can be used to create a suitable seedbed for planting while still maintaining soil structure.

Rotary Tiller

This type of tillage equipment uses rotating blades to break up the soil. While it is not typically used in conservation tillage systems, it can be used to prepare a seedbed for planting in certain situations.


 A harrow is a type of tillage equipment that uses a series of teeth or tines to break up soil and level the seedbed. It can be used in conservation tillage systems to prepare the soil for planting.

Kelly Tillage System is a robust, versatile machine requiring minimal servicing or spare parts. Along with offering conservation tillage, it has become a multi-use implement for Australian farmers.

Advantages of Conservation Tillage with Kelly Tillage System

There are several advantages of getting the Kelly Tillage system for conservation tillage, including:

Reduced Soil Erosion

 Conservation tillage helps reduce soil erosion caused by wind and water by minimising soil disturbance. This helps to preserve soil fertility and reduce nutrient loss.

Improved Soil Health

It helps maintain soil structure and reduce compaction, improving soil health and increasing water infiltration.

Lower Costs

This tillage method reduces the amount spent on fuel, labour, and equipment needed for tillage, resulting in lower costs for farmers.

Increased Crop Yields

 In some cases, conservation tillage has been shown to increase crop yields due to improved soil health and reduced soil erosion.

Environmental Benefits

 Conservation tillage can reduce greenhouse gas emissions, as it requires less fuel and energy than traditional tillage practices.

Reduced Water Usage

By improving soil structure and moisture retention, conservation tillage can help to reduce water usage in crop production.

So, using the Kelly Tillage system for shallow tillage is a sustainable farming practice that offers a range of benefits for farmers and the environment.
