Fertilizer Control Order (FCO) is a crucial regulatory framework implemented by governments to ensure the quality, availability, and proper use of fertilizers. It serves as a mechanism to monitor and regulate the production, distribution, labeling, and sale of fertilizers, with the ultimate goal of promoting sustainable agriculture and safeguarding the interests of farmers and consumers.
The FCO encompasses a wide range of provisions and regulations that govern various aspects of the fertilizer industry. One of its primary objectives is to ensure the quality of fertilizers available in the market. The FCO sets specific standards for nutrient content, physical characteristics, impurities, and labeling requirements. By enforcing these standards, the FCO aims to prevent the sale of substandard or adulterated fertilizers that could have detrimental effects on crop productivity and soil health.
Another key aspect of the FCO is the regulation of fertilizer pricing. Governments often intervene to control the prices of fertilizers to make them affordable for farmers. The FCO may include provisions to monitor and control the pricing of fertilizers, ensuring that they remain accessible to farmers while preventing price manipulation and exploitation.
The FCO also addresses the licensing and registration of fertilizer manufacturers, importers, and distributors. Manufacturers and importers are required to obtain licenses or registrations from the designated regulatory authorities. This helps in maintaining a record of fertilizer producers and suppliers, ensuring accountability, and enabling traceability in case of any quality-related issues or non-compliance.
To ensure compliance with the FCO, regulatory bodies are empowered with inspection and monitoring mechanisms. They conduct regular inspections of fertilizer manufacturing facilities, storage sites, and distribution channels to verify compliance with quality standards, labeling requirements, and other provisions of the FCO. Non-compliance can lead to penalties, fines, or even suspension of licenses, acting as a deterrent for violations and promoting adherence to the regulations.
The FCO also addresses the issue of fertilizers' safe and efficient use. It may mandate the inclusion of information on fertilizer labels regarding dosage, application methods, and safety precautions. This helps farmers make informed decisions about fertilizer application, preventing excessive or improper use that can lead to environmental pollution, nutrient imbalances, and crop damage. The FCO may also encourage the promotion of organic and biofertilizers, providing incentives and support for their production and utilization.

Maize crazy top is a viral disease that affects maize plants (corn). It is caused by a specific strain of the Maize Chlorotic Mottle Virus (MCMV), known as the "crazy top" strain. This disease can cause significant yield losses in affected crops.
The name "maize crazy top" comes from the distinctive symptoms it produces in infected plants. Here are some common symptoms associated with this disease:
Abnormal tassel development: Infected maize plants often exhibit abnormal tassel growth. Instead of a normal tassel structure, the tassels can become deformed, stunted, or exhibit excessive branching. The tassels may appear bushy, distorted, or "crazy" in their growth pattern.
Witches' broom-like appearance: The tassels may develop numerous small, leafy shoots, resembling a broom or a brush. These extra shoots can give the tassels a dense, bushy appearance.
Reduced ear development: The disease can also affect ear development, leading to smaller or misshapen ears. In severe cases, the ears may fail to form entirely.
Yellowing and stunting of plants: Infected plants often exhibit general yellowing or chlorosis of the leaves. The growth of infected plants may be stunted compared to healthy plants.
Maize crazy top is primarily spread by insect vectors, particularly leafhoppers. These insects acquire the virus by feeding on infected plants and then transmit it to healthy plants. The disease can also be spread through the use of infected seed.
There is no cure for maize crazy top once a plant is infected. Prevention and control measures are focused on managing the insect vectors and utilizing disease-resistant maize varieties. Practices such as crop rotation, removing infected plants, and controlling weeds can also help reduce the spread of the disease.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Order
SUBMITTED TO,
Dr. MAGESHEN VR
Dr. Sabareeshwari V
Assistant professor
(Soil Science)
19SAC301 – Manures, Fertilizers & Soil Fertility Management 3 (2+1)
2. Introduction
• Fertilizer Control Order (FCO) is a regulatory
framework established by the Government of
India to ensure the quality of fertilizers sold in
the country.
• The main purpose of FCO is to regulate the
manufacture, distribution, sale, and import of
fertilizers to protect farmers from substandard
or adulterated fertilizers.
• Fertilizers play a crucial role in agriculture by
providing essential nutrients to crops to
enhance their growth and yield. Therefore,
regulating fertilizers is essential for ensuring
food security and sustainable agriculture in
India.
3. Background of
FCO
The first
Fertilizer
Control Order
was introduced
in 1957 to
regulate the
quality and
distribution of
fertilizers in
India.
Over the years,
several
amendments
were made to
the original
order to keep
pace with the
changing needs
of the industry
and the
agricultural
sector.
In 1985, FCO
was amended to
include stricter
quality control
measures and
labeling
requirements to
ensure that
farmers have
access to high-
quality
fertilizers.
4. Objectives
The main objectives of FCO are to ensure the quality of fertilizers, protect
farmers from substandard or adulterated fertilizers, and promote
sustainable agriculture.
FCO aims to achieve these objectives by regulating the manufacture,
distribution, sale, and import of fertilizers and by specifying quality
standards, labeling requirements, and licensing and registration procedures.
5. Types of Fertilizers
Fertilizers can be broadly
categorized into two types: organic
and inorganic.
Organic fertilizers are derived from
natural sources such as animal
manure, plant residues, and
compost, while inorganic fertilizers
are synthesized from chemicals.
Inorganic fertilizers are further
classified into three types:
nitrogenous, phosphatic, and
potassic, based on their nutrient
composition.
6. Quality Control
FCO specifies quality parameters for various types of fertilizers to ensure that
they meet the minimum standards of purity, strength, and composition.
These quality parameters include the minimum percentage of nutrient content,
maximum permissible limits of impurities, and physical characteristics such as
particle size and moisture content.
Fertilizer samples are collected from manufacturers, importers, and distributors,
and tested in accredited laboratories to determine whether they meet the quality
standards specified in FCO.
7. Labeling and Packaging
FCO mandates that
all fertilizers sold
in India must be
labeled with
specific
information to help
farmers identify
the product and its
quality.
The label must
include the name
and address of the
manufacturer or
importer, the
brand name, the
type of fertilizer,
the nutrient
content, and the
batch number.
The packaging must also
comply with certain
specifications, such as
being tamper-proof and
resistant to moisture, to
ensure that the fertilizer
remains safe and
effective during storage
and transportation.
8. Licensing and Registration
• FCO requires all fertilizer manufacturers and importers to obtain a license or
registration from the government before they can start their operations.
• The license or registration is granted only if the applicant meets the eligibility
criteria, such as having the required technical and financial resources, and
complying with the quality standards and labeling requirements specified in
FCO.
• The license or registration must be renewed periodically, and the authorities
can revoke it if the licensee violates any of the provisions of FCO.
9. Enforcement of FCO
• The enforcement of FCO is the
responsibility of various authorities, such as
the Central Fertilizer Quality Control and
Training Institute (CFQC&TI), State
Fertilizer Control Laboratory, and Fertilizer
Control Order Enforcement Wing.
• These authorities conduct inspections,
collect samples, and test fertilizers to ensure
compliance with the provisions of FCO
10. FCO specifies penalties for violating its provisions, which include
imprisonment and fines.
The severity of the penalty depends on the nature and extent of the
violation, such as selling substandard or adulterated fertilizers,
mislabeling, or operating without a license.
The authorities can also seize and destroy the non-compliant
fertilizers to prevent their sale to farmers.
11. Impact of
FCO FCO has had a significant impact on the fertilizer
industry and the agricultural sector in India.
It has helped to improve the quality of fertilizers
sold in the country and protect farmers from
substandard or adulterated fertilizers.
FCO has also promoted sustainable agriculture
by encouraging the use of high-quality fertilizers
that are effective and safe for the environment.
Overall, FCO has played a crucial role in ensuring food
security and promoting rural development in India.
12. Challenges and
Future Prospects
• FCO faces several challenges, such as the
proliferation of spurious and counterfeit
fertilizers, inadequate testing facilities, and lack
of awareness among farmers.
• To address these challenges, the government
needs to strengthen the enforcement of FCO,
invest in testing facilities, and increase
awareness among farmers about the importance
of using high-quality fertilizers.
• The future outlook for FCO is positive, with the
government committed to promoting sustainable
agriculture and ensuring food security through
effective regulation of fertilizers.
13. • The Fertilizer Control Order (FCO) is a vital regulatory framework in
India that governs the production, distribution, and sale of fertilizers.
It ensures that farmers receive high-quality fertilizers that are safe for
the environment and beneficial for crop growth. The FCO sets quality
standards for fertilizers, including their nutrient content, labeling,
packaging, and maximum permissible limits for various chemical
compounds.
• The FCO's implementation has helped to increase agricultural
productivity and promote food security in India. The mandatory
registration of fertilizers with the Central Fertilizer Quality Control
and Training Institute (CFQC&TI) ensures that only quality fertilizers
are sold in the market, and non-compliance with the FCO can result in
legal action, including fines, cancellation of registration, and
imprisonment.
• The FCO is a dynamic regulation that evolves with changes in
technology, scientific knowledge, and agricultural practices, and its
continued implementation is crucial for the sustainable development
of the agricultural sector in India.
