Vídeo: Conceito 4C na redução da emissão de gases do efeito estufa

O IPNI Brasil apresenta a versão em português do vídeo sobre o manejo 4C (aplicação da fonte certa, na dose certa, na época certa e local certo), para minimizar a emissão de gases do efeito estufa. Os ...

Video on 4R Nutrient Stewardship’s Role in Reducing Greenhouse Gas Emissions

September 30, 2014 – Peachtree Corners, Georgia, US – The International Plant Nutrition Institute (IPNI) has just released a new video animation explaining how farmers make 4R decisions (i. e. , decis ...

Project Description - Determining the Environmental Optimum Rate of Fertilizer N for Irrigated Crops in the Semiarid Prairies

Objectives: The primary goal of this project is to identify the environmental optimum rate of fertilizer N (i. e. , the rate that provides the greatest yield increase with the lowest FIE) for irrigate ...

Project Description - Climate Change Mitigation and Adaptation through Conservation Agriculture and Precise Nutrient Management in Current and Future Cereal-based Cropping Systems of the Indo Gangetic Plains

Research Concept The Green Revolution has been a global agricultural success story of the second half of the 21st century. The success has led to food self-sufficiency in the post populous regions of ...

2012 Annual Interpretive Summary - Nitrogen dynamics under elevated carbon dioxide

By 2070, atmospheric carbon dioxide (CO2) concentration is expected to double that observed in 1950. In this higher CO2 world, the sustainability of global crop production may be in jeopardy unless cu ...

Growth, yield and photosynthetic responses to elevated CO2 in wheat genotypes - Growth, Yield and Water Use of Wheat under Elevated Carbon Dioxide

The Australian Grains Free Air Carbon Dioxide Enrichment (AGFACE) project in Horsham, Victoria was designed to simulate atmospheric carbon dioxide levels in the year 2050 and then to use those data to ...

Climate Change Mitigation and Adaptation through Conservation Agriculture and Precise Nutrient Management in Current and Future Cereal-based Cropping Systems of the Indo Gangetic Plains

The project aims to quantify the soil and environmental health indicators under conservation agriculture and precise nutrient management to develop strategies to counteract the changing weather condit ...

2011 Annual Interpretive Summary - Nitrogen dynamics under elevated carbon dioxide

Elevated atmospheric CO2 affects growth and yield which then affect processes controlling the supply and losses of N to sustain these increases. This research was undertaken to measure the effects of ...

CROP NUTRITION WITH LOWER EMISSION OF NITROUS OXIDE

Nitrous oxide is one of several greenhouse gases considered responsible for the warming trend in the climate. Pound for pound, it is deemed about 300 times more effective in trapping heat than carbon ...

2010 Annual Interpretive Summary - Nitrogen dynamics under elevated carbon dioxide

The effect of elevated carbon dioxide concentration ( CO2 ) on greenhouse gas emissions from semi-arid cropping systems is poorly understood. Two studies were reported during 2010, one from the Austra ...

Nitrous Oxide Emissions from Bermudagrass Turf Fertilized with Slow Release and Soluble Nitrogen Sources

Nitrous oxide is an important greenhouse gas (GHG) and the majority of emissions in the USA are from agriculture. Most of this comes from the soil and is linked to soil management and nutrient use. Al ...

2009 Annual Interpretive Summary - Nitrogen dynamics under elevated carbon dioxide

The Australian Grains Free Air Carbon Dioxide Enrichment (AGFACE) facility was established to compare wheat growth, yield, and development under ambient atmospheric carbon dioxide (a CO2 ~380 ppm) and ...

Project Description - Nitrogen dynamics under elevated carbon dioxide

It is known that N demand is lower under eCO2 and this reduces the rate at which N is cycled through the soil/plant system. The low availability of N progressively suppresses the positive response of ...

Project Description - Growth, Yield and Water Use of Wheat under Elevated Carbon Dioxide

Because of uncertainty about the effects of rising atmospheric carbon dioxide levels on crop growth, water use, grain yield and quality, there is a need to obtain data from field experiments conducted ...

Growth, Yield and Water Use of Wheat under Elevated Carbon Dioxide

Research on how elevated carbon dioxide will affect the growth and yield of wheat crops under future climates.

Nitrogen dynamics under elevated carbon dioxide

How will high carbon dioxide concentrations affect the cycling of nitrogen in crop production systems.

Greenhouse Gas Emissions from Cropping Systems and the Influence of Fertilizer Management

Scientific staff of the International Plant Nutrition Institute (IPNI) have prepared a literature review to extend information that will lead to a better understanding of fertilizer N management pract ...
