Why farmers today need to take up precision farming

The century’s most valuable innovation in farm management is based on using Information and Communications Technologies An irrigation sprinkler powered by a solar pump under precision farming.


Information and technology-based farm management system identifies, analyses and manages variability in fields by conducting crop production practices at the right place and time and in the right way, for optimum profitability, sustainability, and protection of the land resource.



Although a considerable research effort has been expended, it is still only a portion of farmers who have practiced any type of precision agriculture (PA) technologies system approach to re-organize the total system of agriculture towards low-input, high-efficiency, and sustainable agriculture.


Precision farming is an approach where inputs are utilized in precise amounts to get increased average yields, compared to traditional cultivation techniques. In India, one major problem is the small field size. More than 58 percent of operational holdings in the country have a size of less than one hectare (ha).


Only in the states of Punjab, Rajasthan, Haryana, and Gujarat do more than 20 percent of agricultural lands have an operational holding size of more than four ha. Commercial, as well as horticultural crops, also show a wider scope for PA in the cooperative farms.


Sustainable PA is this century’s most valuable innovation in farm management that is based on using Information and Communication Technologies (ICTs). This is the most recent innovative technology based on sustainable agriculture and healthy food production and it consists of profitability and increasing production, economic efficiency and the reduction of side effects on the environment.


Challenges :


Research suggests educational and economic challenges as the two most important in the application of precision agriculture. Among the variables that contribute to educational challenges, lack of local experts, funds, knowledgeable research and extension personnel have more of an impact compared to others. PA and initial costs have more of an impact on the economic challenges compared to the other issues.


Why precision farming :


To increase agriculture productivity

Prevents soil degradation

Reduction of chemical application in crop production

Efficient use of water resources

Dissemination of modern farm practices to improve the quality, quantity and reduced cost of production

Developing favorable attitudes

Precision farming changing the socio-economic status of farmers



Advantages :


Agronomical perspective 

Technical perspective

Environmental perspective

Economic perspective 

Precision farming enables climate-smart agri-business


Climate-smart agriculture is necessary for achieving the goal. PA at the appropriate level in food insecure countries is also a powerful tool once it is applied appropriately, based on local crop and site-specific conditions. Consequently, the adoption of new techniques in less-developed areas should start with a basic, affordable, and effective mix of technologies and practices.


Agricultural extension via digital advisory services

Adoption of best practices is critical and digital communication is necessary to bridge the technology gap. Agricultural extension plays a key role in technology dissemination and the private sector is increasingly active in this domain.


Today, Digital Advisory Services (DAS) are either part of the offering of input providers or stand-alone for profit, typically start-up platforms. In the first case and with few exceptions, existing free DAS is a differentiation tool to promote the use of the manufacturers’ core products. The main barriers to DAS adoption are limited digital infrastructure and illiteracy, areas where India has significant advantages over most of Sub-Saharan Africa.


Drip irrigation :


In addition to its advantages over other types of irrigation for improving yields, drip irrigation is the best delivery system for soluble fertilizers. It also drastically reduces the propagation of weeds and the need for herbicides. Foreign — principally Israeli — and local leading brands dominate the established micro irrigation market in India.


Solar pumps :


Solar pumps that lift well water to feed drip systems are a benefit multiplier. Yet the introduction of solar pumps is slow despite their zero carbon footprint and low-maintenance photovoltaic technology. According to official estimates, over twenty million well pumps operate today in India, roughly split between electric and diesel at a solar unit cost ranging from $1,500 to $10,000 for multiple farmers. Changes to subsidy policies now underway may help pave the way for mass adoption and hence further increase the role of private firms contributing to the proliferation of solar pumps.


Soil and crop monitoring :


Imagery-equipped drones are often technically and financially affordable for small farmer communities, also particularly suited for small plots and contract farming. Early detection and correction of soil and crop deficiencies is a win-win proposition for both farmers and off-takers. If purchased and operated by large agri-businesses, the investment in drones and imagery analysis can be factored into the product price paid to farmers.


Extending the usage of equipment for soil and crop monitoring to farming cooperatives and contract farms also benefits from new forms of Capex utilization led by the private sector, now spreading from developed countries into emerging markets.


Technology :


Technologies include a vast array of tools of hardware, software, and equipment

Global Positioning System (GPS) receivers

Differential Global Positioning System (DGPS)

Geographic information systems (GIS)

Remote sensing

Variable Rate Applicator

Combine harvesters with yield monitors

Drawbacks of precision farming  



High cost


Lack of technical expertise knowledge and technology

Not applicable or difficult/costly for small landholdings

Heterogeneity of cropping systems and market imperfections

The policy approach to promote precision farming at the farm level  



Identify the niche areas for the promotion of crop-specific precision farming


Creation of multidisciplinary teams involving agricultural scientists in various fields, engineers, manufacturers and economists to study the overall scope of precision agriculture

Provide complete technical backup support to the farmers to develop pilots or models, which can be replicated on a large scale

The pilot study should be conducted on farmers’ fields to show the results of precision agriculture implementation

Creating awareness among farmers about the consequences of applying imbalanced doses of farm inputs like irrigation, fertilizers, insecticides, and pesticides
