Dear Readers,

Carbon sequestration is on the agenda.
Carbon sequestration is on the agenda. Near Changsha, China, this experiment by the Institute of Soil Science, Chinese Academy of Sciences, in Nanjing, compares various treatments with mulching of paddy rice with the previous season's straw. Moreover, some of the treatments look at No Till practices in rice. These all may lead to increased organic matter content in soils, thus sequester more atmospheric carbon into the soil.

In this edition of e-ifc we present four papers:

"Higher Yields and Reduction of Incidence of Stem Brittle in White Carnation by Increasing Potassium Concentration and NO3-:NH4+ Ratio in the Fertigation Medium" from Israel.

"Effect of Applied Potassium in Increasing the Potential for Nitrogen Assimilation in Spinach (Spinacia oleracea L.)", which highlights research from India.

"Preliminary Field Observations on the Response of Wheat and Barley to High Rates of K Fertilization in Rainfed and Irrigated Regions in Lebanon".

"Potassium and CO2 Sequestration" position paper.

These papers highlight the work of different research groups including results on advanced fertigated systems, physiological work conducted in the laboratory, and large-scale field observations on the response of wheat and barley to applied potassium.

But we need also to look to the future, and mitigation of greenhouse gasses (GHG) is undoubtedly one of the challenging issues ahead of us. We cannot claim to solve the problem of GHGs through better fertilization practices alone but, with the adoption of these practices, we are able to make a contribution in reducing emissions and also increase carbon sequestration. A model currently being developed by one of our members clearly demonstrates that, with adequate K fertilization, and to a larger extent, with improved overall nutrient management, the potential for carbon sequestration in the soil is markedly increased. To find out more, please read the IPI Position Paper on this issue.

Finally, we are excited to announce that the IPI website has a fresh look. We hope this will further increase the value of the information available.

I wish you all an enjoyable read.
