Agriculture has always been a cornerstone of the Nigerian economy, contributing significantly to the country’s Gross Domestic Product (GDP) and providing livelihoods for millions of people.
Sack farming, also known as vertical or container farming, is an innovative agricultural practice that involves growing crops in sacks filled with soil or other growing mediums.
However, with rapid urbanization, arable land in Nigeria’s cities is shrinking, and the traditional farming methods that rely on vast tracts of land are becoming increasingly unsustainable for urban dwellers.
In response to these challenges, innovative farming methods like sack farming have emerged, offering a sustainable and profitable alternative for city dwellers and small-scale farmers alike.
This feature explores sack farming as a viable agribusiness venture in Nigeria, highlighting its benefits, steps to get started, capital requirements, profit potential, and overall profitability.
The Rise of Sack Farming
Sack farming method is particularly suitable for urban areas where space is limited, as it allows for the cultivation of vegetables and other crops in a vertical arrangement, making efficient use of available space. Sack farming has gained popularity in Nigeria due to its affordability, low maintenance requirements, and ability to produce high yields in small spaces.
The concept of sack farming is not entirely new. It has been practiced in various forms across the world, particularly in regions where land is scarce or where traditional farming methods are impractical. In Nigeria, however, sack farming is increasingly being recognized as a viable agribusiness venture, especially in urban areas like Lagos, Abuja, and Port Harcourt, where the demand for fresh vegetables is high, and access to arable land is limited.
Why Sack Farming?
There are several reasons why sack farming is an attractive option for aspiring agripreneurs in Nigeria:
Space Efficiency: Sack farming allows for the cultivation of a wide variety of crops in small spaces. This is particularly beneficial in urban areas where land is expensive and scarce. By growing crops vertically, farmers can maximize their use of space, making it possible to grow more food in less area.
Low Start-Up Costs: Compared to traditional farming, sack farming requires minimal capital investment. Sacks, soil, seeds, and water are the primary inputs, making it an accessible option for people with limited financial resources.
Water Efficiency: Sack farming is known for its efficient use of water. The sacks retain moisture, reducing the amount of water needed for irrigation. This is particularly advantageous in regions prone to water scarcity or during the dry season.

Ease of Management: Sack farming is relatively easy to manage, even for beginners. The controlled environment within the sacks reduces the risk of pests and diseases, and the vertical arrangement makes it easier to tend to the crops.
High Yield Potential: Despite the small space, sack farming can produce surprisingly high yields. With proper management and the right choice of crops, farmers can achieve multiple harvests throughout the year.
Environmental Sustainability: Sack farming contributes to environmental sustainability by reducing the need for large-scale land clearing and minimizing soil erosion. It also encourages the recycling of organic waste, which can be used as compost to enrich the soil in the sacks.
Getting Started with Sack Farming
Starting a sack farming venture in Nigeria is relatively straightforward. Here’s a step-by-step guide on how to get started:
Choose the Right Location
The first step in sack farming is to choose an appropriate location. The ideal location should receive adequate sunlight (at least six hours per day) and be easily accessible for watering and maintenance. Rooftops, balconies, and small backyards are excellent options for urban dwellers.
Select Suitable Crops
Choosing the right crops is crucial for the success of your sack farming venture. Vegetables like tomatoes, peppers, spinach, lettuce, and herbs such as basil and mint are ideal for sack farming. These crops have relatively short growing cycles and can be harvested multiple times throughout the year. Additionally, they are in high demand in urban areas, ensuring a ready market for your produce.
Prepare the Sacks
The next step is to prepare your sacks. You can use any sturdy, breathable material, such as jute or hessian sacks. Plastic sacks can also be used, but it’s essential to ensure they have adequate drainage holes at the bottom to prevent waterlogging. Fill the sacks with a mixture of topsoil, compost, and organic manure. This will provide the necessary nutrients for your crops to thrive.
Planting
Once the sacks are ready, it’s time to plant your seeds or seedlings. Make small holes in the soil and place the seeds or seedlings at the appropriate depth. Be careful not to overcrowd the sacks, as this can lead to competition for nutrients and reduced yields. Depending on the crop, you may need to water the sacks daily or every other day.
Maintenance
Maintaining a sack farm involves regular watering, weeding, and monitoring for pests and diseases. Because the sacks retain moisture well, it’s essential not to overwater your crops, as this can lead to root rot. Regularly check the sacks for signs of pests, such as aphids or caterpillars, and use organic pest control methods if necessary.
Harvesting
One of the advantages of sack farming is the ability to harvest crops continuously. As your vegetables mature, you can begin harvesting the outer leaves or fruits, allowing the plant to continue producing. This method, known as “cut and come again,” ensures a steady supply of fresh produce throughout the growing season.
Capital Requirements for Sack Farming
The beauty of sack farming lies in its affordability and low entry barrier, making it an excellent option for aspiring agripreneurs with limited capital. Below is a breakdown of the estimated costs to start a small-scale sack farming venture in Nigeria:
Sacks: Depending on the size and material, sacks can cost between N100 and N300 each. For a small-scale operation with 100 sacks, the cost would be approximately N10, 000 to N30, 000.
Soil and Manure: A good quality topsoil mix and organic manure are essential for healthy crop growth. The cost for soil and manure for 100 sacks would be around N20, 000 to N30, 000.
Seeds/Seedlings: The cost of seeds or seedlings varies depending on the crop. For a mix of vegetables like tomatoes, spinach, and peppers, you can expect to spend about N10, 000 to N15,000.
Watering Can/Drip Irrigation System: A watering can may cost around N2, 000 to N5,000. A more efficient drip irrigation system, if preferred, could cost between N20,000 and N50,000, depending on the scale.
Miscellaneous Tools: This includes basic farming tools such as hoes, trowels, and gardening gloves, which would cost approximately ₦5,000 to ₦10,000.
Labour: If you require additional help for setting up and maintaining your farm, labor costs will vary depending on the scale of your operation and your location. For a small-scale farm, you might budget around N10, 000 to N20, 000 per month.
Total Initial Investment: The total initial investment required for a small-scale sack farming venture (with 100 sacks) would range from approximately N60, 000 to N155, 000.
Profitability and Market Potential
Sack farming is not just a subsistence activity; it has significant potential as a profitable agribusiness venture. Here’s how:
Yield Potential: Depending on the crop, each sack can yield a substantial amount of produce. For instance, one sack could yield up to 4 kg of tomatoes per cycle, with multiple cycles possible per year. With 100 sacks, you could potentially harvest 400 kg of tomatoes in a single cycle.
Revenue: If the average market price for tomatoes is N500 per kg, 400 kg would generate N200, 000 in revenue per cycle. With three cycles per year, that amounts to N600, 000 annually from tomatoes alone.
Profit Margin: After deducting expenses such as seeds, water, and labor (estimated at ₦200,000 per year), the profit from a small-scale sack farming operation could be around ₦400,000 annually.
This example uses tomatoes as a reference, but the same logic applies to other high-demand vegetables like peppers, spinach, and lettuce. The profitability can vary based on crop choice, scale, and market prices. Additionally, sack farming allows for value addition, such as processing vegetables into packaged salads, juices, or dried herbs, further increasing profitability.
How Lucrative Is Sack Farming?
Sack farming’s profitability hinges on several factors, including the choice of crops, the scale of operation, and effective market access. In urban areas where the demand for fresh, organic produce is high, sack farming can be incredibly lucrative. The relatively low start-up costs and the potential for high yields make it an attractive option for those looking to start an agribusiness with limited capital.
The versatility of sack farming also allows farmers to experiment with different crops, optimizing for market demand and profitability. For instance, leafy vegetables like spinach and lettuce have shorter growing cycles and can be harvested multiple times a year, providing a steady income stream.
Moreover, sack farming can easily scale. Once a farmer masters the basics and starts generating profits, expanding the operation by adding more sacks or exploring other high-value crops is straightforward. This scalability is a crucial factor in its potential as a sustainable and lucrative business.
Challenges and Solutions
Like any agricultural venture, sack farming comes with its challenges. These include: Pest and Disease Management: While sack farming reduces the risk of pests and diseases, it does not eliminate it entirely. Farmers must be vigilant and use organic pest control methods to protect their crops.
Watering: Although sack farming is water-efficient, it requires consistent watering, especially during the dry season. Drip irrigation systems or rainwater harvesting can help mitigate this challenge.
Soil Degradation: Over time, the soil in the sacks may become depleted of nutrients. Regularly adding compost and organic manure can help maintain soil fertility.
Market Access: Accessing markets can be a challenge for urban farmers, especially if they are producing on a small scale. Forming cooperatives or partnerships with other farmers can help in accessing larger markets and reducing transportation costs.
Sack farming presents a unique opportunity for Nigerians to engage in profitable agribusiness, even in urban settings with limited space. Its low start-up costs, ease of management, and potential for high yields make it an attractive venture for aspiring agripreneurs. By embracing sack farming, Nigerians can contribute to food security, reduce the environmental impact of traditional farming, and create sustainable livelihoods in the process.
As more people in Nigeria’s urban areas recognize the benefits of sack farming, this innovative method has the potential to transform urban agriculture and play a crucial role in feeding the nation’s growing population. With the right knowledge, resources, and dedication, sack farming can be a highly successful and rewarding agribusiness venture.
