US. Both production and application of fertilizers result in GHG emissions, either as CO 2 or N 2O. How does fertilizer contribute to climate change and what is being done to prevent this? Therefore, IFDC, our research partners, and the industry are responsible for both continuing to increase manufacturing efficiencies and, more importantly, developing truly novel fertilizer products that feed the plant. Even with all our efforts to reduce losses with the current products, we will not be able to stay within the “safe operating space of our planetary boundaries”. Evidence shows that fertilizer products, not just practices, must be changed and improved for our planet to stay within safe boundaries.

Such was a case I saw in Asia, where vegetable farmers were using more than 1,000 kg of nitrogen per hectare! In cases like this, and in European agriculture decades ago, this 4R approach will simply help reach easy benefits for farm productivity and environmental protection.īut it’s unfair to leave the burden of responsibility solely with the farmers and their practicing of the 4Rs. PB. Practicing the 4Rs is the first step to take if the use efficiency of fertilizers is very low.

Right place: soil-root interaction may involve banding, broadcast, deep placement, etc.

Right rate: based on soil test, plant tissue analyses, spectral techniques, and variable rate application sensors.

Right time: single versus split application.

The remaining three aspects of 4R include nutrient application at the: The 4Rs include all nutrient management: right sources include conventional fertilizers as well as organic fertilizers and amendments, or combination of these sources. The latter results in reduced environmental impact. US. The 4Rs lead to improved nutrient-use efficiency (NUE), increased yield and profitability, and reduced nutrient losses.

What purpose do the 4Rs (right source, right rate, right time, right place) serve? Bindraban leads IFDC’s FERARI program and is a veteran researcher in fertilizers, soil health, planetary boundaries, and global food systems. Singh is Deputy Director of IFDC Headquarters Research and specializes in soil fertility and systems modeling. Prem Bindraban to discuss this year’s topic of sustainability for Global Fertilizer Day. We had the opportunity to sit down with Dr.
