NUTRIENT STEWARDSHIP

Nutrient stewardship refers to the efficient and effective planning and management of plant nutrients in a manner that improves the social, economic and environmental performance of mineral and organic fertilizers

Nutrient stewardship is implemented for instance through site-and crop-specific implementation of scientific management principles related to source, rate, timing and placement.

In line with its Mission to promote the efficient and responsible production, distribution and use of plant nutrients, IFA communicates extensively on nutrient stewardship. IFA also partners with farmers, research and extension organizations to share knoweldge on Fertilizer Best Management Practices worldwide.

In 2016, IFA and the World Farmers' Organization (WFO) released the Nutrient Management Handbook , in cooperation with The Global Alliance for Climate-Smart Agriculture (GACSA) . The Nutrient Management Handbook is a 25-page manual to help farmers achieve the triple win of boosting productivity, achieving higher resilience and reducing greenhouse gas emissions. The handbook answers critical questions such as:

• Which nutrients are essential for plant growth?
• What are the challenges of nutrient management, and how can they be tackled?
• How does water interact with plant nutrients?
• How can I use fertilizer in a way that will make my farm “climate-smart”?

The 4Rs

Nutrient stewardship initiatives encourage farmers to follow the “4Rs principles” of using the right nutrient source at the right rate, at the right time and in the right place, so that fertilizer application can be managed to achieve economic, social and environmental goals set by stakeholders.

The 4Rs nutrient stewardship framework is inclusive and encompassing, and is easily tailored to both developed and emerging countries. It places the farmer – who are the end users of our products – at the core of the decision-making process.

By granting farmers agronomic knowledge of fertilizer best management practices organized in the four areas of nutrient management, they are empowered to increase their yields and income, while improving health of their soils and protecting the environment.

To read about farmers around the workd that are implementing the 4rs and the results they have achieved, head to our Series "Nutrient Management Around the World".

Fertilizer Best Management Practices

Fertilizer best management practices (FBMPs) are agricultural production techniques and practices developed through scientific researches and verified and continuously adapted in the fields to maximize economic, social and environmental benefits.

They are aimed at managing the flow of nutrients in the course of producing affordable and healthy food in a sustainable manner that protects the environment and conserves natural resources at the same time profitable to farmers.

Through FBMPs, the benefits derived from fertilizers are maximized while the losses and negative effects of over/under/or misuse of fertilizers are minimized.

Some examples of FBMPs include:

• Balanced fertilization, i.e. giving the proper supply of all macronutrients and micronutrients in a balanced ration throughout the growth of crops;
• Site-specific nutrient management (SSNM), i.e. supplying plants with nutrients to optimally match their inherent spatial and temporal needs for nutrients;
• Integrated Plant Nutrient Management (IPNM), entails applying avalaible on-farm organic fertilizers to crops and supplementing them with mineral fertilizers;
• Microdosing , a technique that consists in applying small quantities of fertilizers, either during planting or 3 – 4 weeks after plant emergence;
• Fertigation , entails combining fertilizers with irrigation water.

FBMPs should result in improved productivity, profitability and nutrient use efficiency and depends upon farmers having access to the knowledge required to improve management and to a timely supply of quality products.

Agroecology

Agroecology is an integrated approach that simultaneously applies ecological and social concepts and principles to the design and management of food and agricultural systems. The FAO has defined 10 elements of agroecology, available here.

The fertilizer industry strongly encourages for these elements to include:

• Fertilizer Best Management Practices as a key criteria for agroecological practices.
• The inclusion of the 4Rs in the principles of agroecology.
• The inclusion of Integrated Plant Nutrient Management (IPNM) into agroecological practices.

Agroecology shouldn’t be defined by a narrow set of agricultural practices, for instance solely organic practices.

The fertilizer industry supports the inclusion of Integrated Plant Nutrient Management (IPNM) into agroecological practices, as it entails complementing available organic nutrient sources on the farm with mineral fertilizers as necessary to achieve desired yields and restore soil health fertility, when soil testing shows low nutrient levels. Scientific studies have proven to be the best solution for improving crop productivity and soil carbon sequestration
