Sack-farming is a super modern agricultural method of growing crops which involves preparing the soil with organic pesticides, fertilised and bagged with germinated seeds. In simple terms, it is a garden in series of sacks filled with manure, soil and small stones to enable quality water drainage from the top and sides of these sacks often referred to as multi-story garden farm.

Speaking in an interview with the Ghana News Agency at Assin Fosu, during a public sensitisation programme, Mr Manu noted that "the planting method makes good use of land, retain soil fertility and was able to withstand diseases and pests".

Sack farming, otherwise called City farming is practised by all manner of persons and groups regardless of location, profession and land size, adding that "it only requires a small piece of land to grow so many crops therefore reduces the demand for large acre of land for farming."

The technology makes it possible to reduce 10 acre farm to four acres for the same yield especially for vegetables like tomatoes and pepper.Acquiring land for agriculture and other purposes in Ghana had been bedevilled with unending litigations and cumbersome processes that many would want to avoid.

He said the farming system had come to solve the issues of soaring and scary prices of lands that frightened potential agricultural entrepreneurs and the youth to venture into agriculture.

Interestingly, he said the system thrives better even in cities and homes that don't even have much outdoor space especially in urban slums where it was commonly good for the cultivation of vegetables like lettuce carrot, cucumber as well as yam and potatoes.

The modernised farming system, according to him, was the anchor to solving Ghana's unemployment deficit and generates additional income to other economically engaged people to help sustain their livelihoods.

Highlighting on the nutritional values of crops grown using this method, he stated that it offered individuals quality organic vegetables for consumption, food security, and considerably reduce healthcare bill by cleaning carbon concentration in their environment.

"It is fully organic from fertilisation through  pest and fungi control as well as irrigation," he noted. To enable more Ghanaians to enjoy the full benefit of the modern agricultural method of growing crops and vegetables, Ikehman concert and the City Farm and in collaboration with Organic Food Revolution (OFR) had embarked on the of training over 2000 individuals, groups and organisations to grow organic vegetables for its numerous benefits.

It is aimed at educating them on the need to accept the modernised farming method as the best in the most preferred strategy of fighting food poisoning, judicious use of agricultural lands and managing inconsistent flow of rain and weather patterns.

On the international scene, he noted that this type of farming is common in countries such as Kenya Uganda, India, Mozambique, South Africa and the Philippines had converted many large paths into upright gardens.
