Use of Mobile Communication Technology and Information Flow for Crop Yield and ROI Optimizatio

30 May

Use of Mobile Communication Technology and Information Flow for Crop Yield and ROI Optimization

1.      Introduction


Pakistan’s high potential for producing food is an internationally established fact.  However, agriculture sector in Pakistan is facing significant challenges.  Some of these challenges are:

i.            Shortage of water and power.

ii.            Rising cost of inputs.

iii.            Extremely high post harvest wastage of farm produce.

Fortunately, progress in mobile communication and information technology has the potential to provide significant support to farmers in surmounting these challenges.  Some of the technologies that can be leveraged include:

i.            Mobile communication and smart consumer devices like phones, pdas etc.

ii.            Internet and cloud computing.

iii.            Cost effective satellite imaging and image processing.

iv.            Plant growth modeling and simulation.

v.            Knowledge synthesis and data mining.

Integrated use of these technologies can lead to optimization of individual farmer’s operations as well as accurate estimation of total farm production at a fine grain spatial as well as temporal resolution. These fine grain estimates can be used to minimize waste by optimizing use of current supply chain infrastructure as well as accurately identifying gaps in this infrastructure.

A number of efforts have been made to leverage mobile communication to assist farmers. These efforts have had mixed results.  A detailed literature search on this topic is beyond the scope of this document.  One of the key short comings in these efforts has been a lack of analysis and understanding of farmers’ end-to-end information flow requirements. This document describes farmers’ information flow needs for optimizing crop yield and ROI.  Major steps in farming, farmer’s information needs for each step, sources of information, challenges and bottlenecks in receiving information and technologies for addressing these challenges are described.

2.      Major Steps in Farming


A farmer takes following eight major steps from crop selection to harvesting:

i.            Crop Selection

ii.            Land Preparation

iii.            Seed Selection

iv.            Seed Sowing

v.            Irrigation

vi.            Crop Growth

vii.            Fertilizing

viii.            Harvesting

3.      Farmers’ Sources of information


Farmers typically rely on following sources of information:

i.            Agriculture department of provincial government.

ii.            Fellow farmers.

iii.            Field agents of seed, pesticide and fertilizer companies.

iv.            TV and radio programs.

v.            Newspapers.

4.      Challenges and Roadblocks in Information Flow


Farmers typically face following challenges in receiving timely and personalized information:

i.            Farmer has to travel to offices of agricultural department for information.  This is a costly and time consuming activity.  Availability of government officials is unpredictable.

ii.            Radio or TV programs are broadcast at a predefined schedule which may or may not be convenient for the farmer.  Information should be available to the farmer on demand and should be personalized to his needs. Majority of farmers in villages either do not have access to newspapers or lack of education makes their access limited.

iii.            Most of the information broadcast may not be specific to a farmer’s needs.

iv.            Fellow farmers don’t have best or most up to date knowledge.

v.            Field agents of pesticide or seed companies are unable to pay frequent and timely visits to all farmers.

5.      Use of Mobile Communication and Information Technologies

A number of information flow problems can be resolved by leveraging information technology to maintain comprehensive personalized knowledge about a farmer’s operations, simulation and modeling tools and two way asynchronous communications between farmers and the IT system using mobile communication technologies.

Cost of these technologies has decreased beyond expectation. Pakistan has one of the least expensive mobile communication networks in the world.  Reasonably priced intelligent mobile devices are capable of taking good quality images and sending these to experts for diagnosis.  Large scale computation for decision making is available all over the world at very affordable prices.  Plant growth modeling and simulation technology is maturing.

6.      Farmers’ Information Needs

Farmers’ information needs for each of these steps are presented next.

6.1  Crop Selection

  • Comparative pricing of different crops.  For some crops government releases prices of the crop at the time of seeding.
  • Market demand and sale potential of the crop.
  • Budget required for the cultivation of each crop.
  • Feasibility of the crop considering climate and quality of land.
  • Crop productivity compared with other alternatives.
  • Affects of any disease in previous crop and steps needed to minimize this impact.
  • Fertilization needed to bring land to its normal fertility depending upon the previous crops and fertilization used.
  • Layout and design of the field with respect to crop and efficient irrigation.
  • Latest techniques for leveling the fields and their cost.
  • Price and quantity needed per acre
  • Average yield and Sprout to sown ratio.
  • Suitability to particular area and climate.
  • Water requirement.
  • Resistance to diseases.
  • Distribution offices.
  • Appropriate time to sow seed.
  • Weather information at sowing time.
  • Best method for the sowing of seeds.
  • Seed sowing depth.
  • Critical time for irrigation.
  • Amount of water to be given to the plants.
  • Frequency of irrigation.
  • Number of plants per unit of are. At times more than optimum number of seeds sprout. Farmers have to reduce density for healthy growth of other plants.
  • Average growth rate of the crop in normal conditions.
  • Comparison of crop growth rate, leaf size, crop color etc. with expected growth for given conditions and input.
  • Interventions needed to maintain expected growth.
  • Frequency, quantity and method for fertilization.
  • Proper time, frequency and method for plowing.
  • Proper time, frequency and method for weeding.
  • Expected pest and virus attacks, symptoms of such attacks, precautionary measure that can be taken in advance to avoid these attacks, immediate actions including pesticide to be used to kill pests and viruses, quantity of pesticide be used per acre,  most effective method for pesticide spray, avoid health issues related to pesticide spray.
  • Proper time and method for harvesting.
  • Comparative market rates.
  • Proper crop storage.
  • Cost of transportation.

6.2  Land Preparation

6.3  Seed Selection

6.4  Seed Sowing

6.5  Irrigation

6.6  Crop Growth

6.7  Harvesting

7.      Conclusions


Pakistan’s agriculture sector is ripe for leveraging information technology and mobile communication to optimize crop yield and ROI. Fortunately, several advances in technology have taken place internationally as well as in Pakistan. Key challenge we face is to develop comprehensive understanding of farmers’ information flow needs and develop integrated solutions that provide information to farmers, when and where needed, at their convenience.  Success of this initiative strongly depends upon receiving accurate and timely information from farmers.  The IT system should be capable of efficient information flow management, knowledge synthesis and information delivery to the farmer.  This will be possible only if farmers perceive value in information this system provides them.

Database Replication in MS SQL Server

18 Aug


For high availability of data in your SQL server, you might require a replica of your database server. To server this purpose you can use MS SQL Server’s mirroring functionality. By using the mirroring feature we can create a replica of our database being synchronized real-time.  Your same data will be saved at two different servers. In MS SQL Server Mirroring there are three different modules i.e.

  • Principal Server (Primary)
  • Mirroring Server(Secondary Server)
  • Witness Server

Practically all three servers are on different machines.  Principal is the server whose database replica will be being synchronized at the Mirroring Server. Witness server performs the failover duties, incase principal server goes down Witness Server will perform automatic failover to make mirroring as principal server. Supporting automatic failover is the only role of the witness.

Mirroring Architecture

Mirroring Architecture

Now how to install database mirroring in MS SQL Server?


  1. MS SQL Server Enterprise/Standard/Workgroup Edition installed on Principal and Mirroring Server while on Witness Sever we can have any SQL Server Edition installed.
  2. Principal, Mirroring and Witness Server must on different machines.
  3. On each server database service should be running with same windows/active directory account and password. This is very important please be careful about this point otherwise you will get errors later.
  4. Run All SQL Servers Service with Same Account

    Run All SQL Servers Service with Same Account

  5. Primary Database (Principal) is in Full Recovery model.
 Full Recovery Database Model

Full Recovery Database Model

Installation Step-By-Step:

Take the back up of desired database (which needs to replicated/mirrored) on the Principal SQL Server.

Create a database with the same name from the Principal SQL Server on the Mirroring SQL Server, then restore the backup on the Mirroring SQL Server with the

Option to Overwrite the existing database checked


Restore DB at Mirroring Server

Restore DB at Mirroring Server

After you click “OK” button, you will see it’s in a Restoring mode as you have chosen the NORECOVERY option and it will be in a permanent Restoring state to prevent users from accessing the database. It will be only user accessible if the database fails over to the Mirror and now the old Principal will go to the recovering state.

Start the mirroring configuration process on the Principal SQL Server. Right-click the Database –> Properties –> Mirroring and click Configure Security.

On the Include Witness Server screen, select “Yes” and click “Next” Button.

Now choose Principal SQL Server Instance:

Now choose Mirror SQL Server Instance:

Choose a Witness Instance:

Now enter the SQL Server Service Accounts for each SQL Server Instance, but if all of your SQL instances are using the same account, then just leave it blank.

Completing the Wizard:

Start the mirroring:

Note: In case of any error check if all the SQL server services are running with same account.

.NET Basics – Do Work in Background Thread to Keep GUI Responsive

30 Dec

Use of .NET BackGroundWorker

Sean's Stuff

One of the most important things that differentiates a “quick and dirty” application from one that has been designed well is how the application’s user interface behaves during lengthy operations.  The quick-and-dirty approach is to just do all of your work in a button’s Click event handler and not worry about the user interface.  The problem with this is that the GUI will freeze up while the application does whatever work it needs to do.

A well designed application, on the other hand, is one that is careful to do as much work as possible in background threads, keeping the GUI responsive and making sure that it makes it obvious to the user that work is going on in the background and adjusts the GUI to disallow any user actions that don’t apply until after the work finishes.

Under .NET 2.0, doing work on a background thread has become a…

Java based OPC UA library replacement to .NET’s DCOM

3 Mar

Inductive Automation uses OPC UA to build its industrial platform on Java and offers the Ignition OPC UA server for free, whether users purchase the Ignition software or not. Keep reading to request a free activation key.

Inductive Automation was the first private organization to write their own OPC Unified Architecture (UA) stack—and they chose to write it completely in Java. The company’s vision was to develop control system software that was not dependent on any particular operating system. The old OPC spec was based on Microsoft’s Distributed Component Object Model (DCOM), which tied every OPC server to Windows. 

In order to achieve their goals of a software platform that would work on any system, Inductive Automation needed an OPC server that wouldn’t lock their software into a Windows-only environment. 

“We made the decision that we wanted everything written in Java so that users would have the freedom to choose their operating system,” said Colby Clegg, software developer for Inductive Automation. “The platform-neutral OPC UA specification enabled us to write our own stack in Java. Now our entire software package is in Java, and this offers a lot of benefits for users.” 

The result was the Ignition OPC UA server, which can work either as a stand-alone OPC server for third-party OPC UA clients, or as part of the comprehensive Ignition software package. In either case, it provides fast, reliable, and secure access to PLC data through its pluggable driver architecture. 

Why Java? 


Java is one of the most popular programming languages in the world (see the TIOBE Programming Community Index for September 2010). Java runs on more types of consumer and embedded devices, smart cards, ATMs, thin clients, PCs, servers, and mainframes than any other language. 

“Java is the ‘write once, run anywhere’ language,” said Steve Hechtman, president of Inductive Automation. “This is a major reason why we selected it. By writing Ignition in Java, it runs equally well on Linux as it does on OSX, Windows or Solaris.”

Java is also highly resistant to viruses. It is designed from the ground up to be more secure than legacy programming languages, offering a rich array of features that prevent many common security holes. That makes it ideally suited to the industrial environment.

“Rather than following the flock and just selecting the current Microsoft technology, we took a step back and evaluated what language provided the most portability, security, stability and support—and Java was the clear winner,” Hechtman said.

Why Free?

Inductive Automation offers the Ignition OPC UA server for free, whether users purchase the Ignition software or not. “We want the market to get excited about the potential of OPC-UA,” explains Clegg, “and in the freedom of selecting your own platform. Plus, once users get started with Ignition, we’re confident that they’ll be blown away by everything it can do.”

The Ignition OPC-UA server is free and can be used with any OPC-UA client: Simply request a free activation key, download the software, and get started using it on your control system. It features an open driver API, and includes free Allen Bradley and Modbus TCP drivers.

The activation key and download page can be accessed here:
