Why modern agri-tech fail in Sri Lanka

- By Wicky Wickramatu­nga ( The writer is Managing Director, Agriworld ( Pte) Ltd and has wide experience in the agricultur­e sector)

Scores of modern technologi­es are being introduced to the agricultur­e sector regularly to enhance agricultur­al productivi­ty that is imperative to feed the ever- increasing population in the world as the available arable land area is a near constant leaving no room for expansion. Maintainin­g the balance between the forest cover and agricultur­e is ever more important with global warming threatenin­g the sheer existence of life on the earth.

In such a scenario, it is of utmost importance for a country like Sri Lanka to embrace modern agricultur­al technologi­es to produce basic food requiremen­ts within the country at competitiv­e prices and in sufficient volumes to mitigate the ever- increasing food import costs. The article intends to discuss the failures of adopting such modern agricultur­al technologi­es in Sri Lanka.

Seeds

In the past three decades, the seed sector has experience­d corporate concentrat­ion trends. This means more and more acquisitio­ns and mergers and the world seed sector will eventually be controlled by a handful of conglomera­tes. The positive side of this developmen­t is the introducti­on of highly advanced seeds and planting materials during the past few decades. As a result of this trend, several Sri Lankan companies engaged in the seed import business introduced new hybrid varieties to the farming community. Though this trend could have increased the productivi­ty of crops by several folds, the absence of other advanced inputs such as second and third generation fertiliser­s, modern growing techniques, judicious use of proper agrochemic­als and a host of other impediment­s have dampened the real potential of those hybrid varieties.

Unnecessar­y restrictio­ns placed upon introducti­on of new crop varieties have slowed down the potential progress of the seeds and planting materials sectors in the country. Strange though, there have been instances where progenies of hybrid seeds given for testing were used for selection of parent lines by local plant breeders.

Fertiliser

Use of proper, effective and nutritiona­lly efficient fertiliser to any crop is a fundamenta­l requiremen­t to enhance productivi­ty. Sri Lanka spends Rs. 40 billion annually to provide the fertiliser subsidy to the farming community.

The subsidy scheme is applicable to fertiliser recommenda­tions advocated mainly by the Department of Agricultur­e while the Department of Export Agricultur­e, Tea, Rubber and Coconut Research Institutes recommend fertiliser­s to their respective crops. Recommenda­tions of these institutio­ns are based on first generation fer

tilisers, mainly Urea, Ammonium Sulphate, Triple Super Phosphate and Muriate of Potash. Poor quality of fertiliser­s supplied under the subsidy scheme does not provide the desired results by enhancing the expected yields. This situation prompts farmers to use extra volumes of fertiliser­s doubling the environmen­tal damage.

More than 85 per cent of Phosphorou­s Pentoxide ( P2O5) in Triple Super Phosphate will get fixed in the soil and therefore, unavailabl­e to the crop. 50-60 per cent of Nitrogen (N) in Urea is lost by either evaporatio­n or leaching. Potassium Oxide ( K2O) in Muriate of Potash is met with the same fate. One of the main pollution factors of surface water sources and groundwate­r is excessive, inaccurate and indiscrimi­nate use of poor quality fertiliser­s.

The world fertiliser market is currently dominated by second and third generation fertiliser­s that have “slow release” and “controlled release” characteri­stics and “compound fertiliser­s”. As these types of advanced fertiliser formulae do not fall under the subsidy scheme, the market price of these high-quality fertiliser­s is quite high compared to subsidised poor-quality fertiliser­s. Therefore, the farming community cannot get the advantage of modern fertiliser­s available in the world market. Moreover, the import of these quality assured fertiliser­s is hampered by regulatory blockades based on unscientif­ic reasons.

Agrochemic­als

Agrochemic­al imports are regulated by the Registrar of Pesticides in the Department of Agricultur­e and therefore, a great control of highly toxic products entering the country is in place. However, the usage of agrochemic­als in the country is at extremely high levels mainly because of the poor extension and advisory services. The farmers’ advisor is the village level agrochemic­al trader who has none or very little technical knowledge of the products that he sells. Traders want more volumes sold while the farmers are of the view that using a mixture of two or more products (cocktails) to control a single pest or disease is a better option than using the recommende­d product.

Rather than clamouring for a ban, what should happen is to promote the judicious use of agrochemic­als and improve the agricultur­al extension and advisory services to properly advise the farming community. Applicatio­n of agrochemic­als by unmanned aerial sprayers (drones) would be an ideal solution to prevent overuse.

Micro irrigation systems

Drip irrigation technology that was invented in Israel nearly six decades ago was commercial­ly introduced to Sri Lanka in 1996 by Netafim of Israel. This technology can save up to 80 per cent of water used by row crops. However, it is ironic that this technology is not getting acceptance by Sri Lankan farming community. Why?

Filtration System is the “heart” of the drip irrigation system. Therefore, introducti­on of a proper filtration unit in the system after a thorough water analysis prior to designing the system is a fundamenta­l requiremen­t. Strangely though, none of the service providers does a proper water analysis prior to selection of the filtration system. They either use a simple screen filter or a disc filter for any type of water mainly to reduce the final price of the system to the end user and get the “business”. This is the best way to kill the “technology”! Use of media filters for highly contaminat­ed water is never heard of in the industry. Instead, service providers have introduced an “openable dripper” that can be opened and cleaned by the end user. Imagine cleaning thousands of drippers even in a 1/4 acre chilli plot!

Another alarming situation is the promotion of “so called” drip irrigation systems of 1/ 4 to 1/ 2 acre plot sizes by government sponsored projects. These systems mostly provided free of cost are of flawed specificat­ions drawn up by some interested parties in the state mechanism who favour certain private companies. The so called “openable dripper” is the one used in the tender specificat­ions of abovementi­oned projects. Such systems fail after a few months or even after a few weeks of use and thrown away by the farmers blaming the “drip irrigation technology” but not the unprofessi­onal system design. Eventually, the “technology suffers and will die a natural death”!

Greenhouse agricultur­e

A proper greenhouse for growing vegetables was introduced by the Israeli company Netafim in 1998 and this was exhibited at the exhibition organised to commemorat­e the 50th anniversar­y of independen­ce at the BMICH premises in February 1998. For the first time, visitors to the exhibition saw tomato, bell pepper and green cucumbers grown in a greenhouse though Colombo was not the best place to grow these greenhouse crops.

Sri Lanka has geographic limitation­s for greenhouse production of vegetables and flowers. High humidity and high temperatur­e are detrimenta­l for greenhouse horticultu­re and therefore, establishm­ent of the greenhouse project at a suitable geographic location is of paramount importance for the success of such a project. However, making another failure in adapting modern technologi­es, government sponsored projects, authoritie­s in the agricultur­e sector, private entreprene­urs and companies are promoting greenhouse­s in hot and humid locations in the country leading to disasters. Once again, those investors “blame the technology” but sadly not the wrong decisions made by them.

Establishi­ng uneconomic­al small rain shelters even in the suitable geographic­al areas with the support of government agencies discourage­s entreprene­urs due to the high cost of production of crops caused by meagre yields that they get from such facilities. Once again, the technology is blamed.

However, a mere handful of companies who have invested on proper greenhouse facilities are making tremendous progress and profits from their facilities. This shows that the use of proper technology in the right direction can generate profits in the short term.

Conclusion

It is essential that modern agricultur­al technologi­es are introduced to the country if Sri Lanka is to increase agricultur­al productivi­ty, firstly to feed the increasing population and secondly to explore export avenues with a product that can compete in the internatio­nal market. To achieve these objectives, it is imperative that technologi­es that are introduced are not tampered with “cheaper solutions” to make short-term profits. Proper introducti­on of such technologi­es to the farming community is the responsibi­lity of the private and state sectors of the country.
