 Nutrient Source Specifics Series New this August ...Single Superphosphate (NSS #21) and Ammonium NItrate (NSS#22) See Details Nitrogen Fertilizer Production and Technology Nitrogen (N) fertilizer input is critical for the production of an adequate food supply for a rapidly increasing world population. This new IPNI presentation on the N fertilizer industry covers the major considerations in N fertilizer production and technology. Read Full StoryGreenhouse 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 practices that minimize global warming potential. Download a copy Fertilizer Nitrogen BMPs to Limit Losses that Contribute to Global Warming The right fertilizer N management decisions in producing corn and other crops can help reduce the impact on greenhouse gas (GHG) emissions and global warming potential. These fertilizer best management practices (BMPs) can go a long way toward making the most of applied N, for economic benefit as well as environmental. Science and experience show that the impact of a fertilizer BMP on crop yield, quality, profitability, and nutrient loss to water or air is greatly influenced by other agronomic practices such as plant population, cultivar, tillage, and pest management, as well as proven conservation practices. A new 8-page publication by IPNI Nitrogen Program Dr. Cliff Snyder, titled “Fertilizer Nitrogen BMPs to Limit Losses that Contribute to Global Warming”, takes a closer look and provides a practical overview. It is available in print or as a PDF file at this site. Click here. Download a copy |
Cotton Response to Combinations of Nitrogen and Potassium  Cotton continues to be one of the major row crops in Mississippi Delta Region of Arkansas. Nitrogen and K fertilization of cotton in Arkansas is based on preplant soil test NO3-N and K levels and petiole NO3-N and K concentrations between first bloom and boll opening. This diagnostic approach is based on field research in late 70's and early 80's and enabled many Arkansas and other mid-south growers to produce high cotton yields for many years. However, cotton production practices have dramatically changed during the past two decades. more on this research Global Crop Intensification Lessens Greenhouse Gas Emissions The global population increased from 3.08 billion in 1961 to over 6.51 billion in 2005 (111% increase), and is expected to reach almost 9 billion by 2050. This growth of the human family will result in a 70% rise in food demand. Can such food production increases be met, and if so, what will the impacts be on greenhouse gas (GHG) emissions and climate change? Read Full Story   Effect of Unrestricted Nitrogen and Irrigation Application on Soil Carbon and Nitrogen Pools in Greenhouse Vegetable Systems In the north China plain, the amount of N fertilizer and irrigation application in greenhouse vegetable systems is about three to five times that in conventional cereal systems. Over a decade of shifting from the conventional cereal systems to greenhouse vegetables, the capacity for nutrient cycling within these greenhouse systems has fallen. Additionally, the content of inorganic C in the soil profile under greenhouse systems has shown a dramatic decline. Read Full Story |
 IPNI at N2010, New Delhi Information related to presentations by IPNI staff at the N2010 Conference held in New Dehli, December 3 to 7, 2010. Read Full StoryUSE OF YIELD GOALS FOR PROVIDING N RATE SUGGESTIONS: GENERAL CONCEPT Recent studies in the North Central region have shown a poor relationship between optimum yield of individual sites and optimum fertilizer N rate. The outcome has been the development of fertilizer recommendation approaches that do not consider site yield goal. This causes one to ponder how so many recommendation programs utilizing yield goal were developed in the first place and have continued in use for more than 40 years. It appears to be an appropriate time to review the general concept of use of yield goals in N recommendations. Such a review is the primary objective of this paper, presented by Paul Fixen at the 2006 Northcentral Extension-Industry Soil Fertility Conference with a secondary objective of relating the traditional concept to the recent studies suggesting a very limited role for yield goal in predicting N fertilizer need. Read Full Story Managing Nitrogen to Protect Water Nitrogen fertilization is essential to crop production. Farmers can’t grow enough food to meet ever increasing world demands without it. The good news is that with proper management of available N fertilizer sources, farmers can achieve their yield goals and sustain water quality at the same time.
