North Sea needs more protection from nutrient inputs
Reductions in the nutrients nitrogen and phosphorus flowing from rivers into the North Sea have had clear benefits on marine health in coastal waters, according to a recent study. However, the reductions are less effective in improving the condition of deeper offshore waters. Tougher measures to manage nutrient loads and prevent eutrophication are recommended. Reductions in nutrient levels in ...

Soil Moisture Probes as a management tool for broadacre cropping enterprises
Are you interested in being involved in a 'Cutting Edge' Agronomic Project and Discussion Group? SANTFA and Rural Directions Pty Ltd, are kicking off a project focussing on Soil Moisture Probes as a management tool for broadacre cropping enterprises, which will run from July 2009 through to May 2010. The project is about using soil moisture monitoring as a guide for making informed decisions in ...

Climate renews famine risk to Africa’s Sahel
The Sahel, the arid belt of land that stretches from the Atlantic to the Red Sea and separates the Sahara desert from the African savanna, is no stranger to drought and famine. Now scientists in Sweden say the Sahel faces another humanitarian crisis even than in the recent past − with the changing climate partly responsible. Writing in the journal Environmental Research Letters, the ...

Secret to Healthy Soil, Black Worm Castings, Organic Fertilizers, Vermaplex
Although it is not apparent, the soil in your garden or farm is living system teaming with life. The ‘soil food web’, is made up of millions of beneficial micro-organisms which supports the development, vigor and production of the plant. These organisms include, nematodes, fungi, protozoa, and bacteria, are also responsible for retaining water and nutrients and disease suppression. ...

Grass-based farming systems: Soil conservation and environmental quality
Crop selection and sequence can have a profound effect on the environment and on farm profitability. According to Chapter 7, “Grass-based Farming Systems: Soil Conservation and Environmental Quality” by Jeremy W. Singer, Alan J. Franzluebbers, and Douglas L. Karlen in the book, Grassland Quietness and Strength for a New American Agriculture, the basis for a productive agricultural system should ...

How to feed the world without destroying the planet
By 2050, there will be another two to three billion people on Earth, and the planet's population will consume twice as much food as now. For 50 years farmland has grown at the cost of natural habitat and biodiversity, and already more than two-thirds of agricultural land is either in use or protected. As a result, we need to develop the technology to double the output of the 10–15 main ...

The Inaugural High-Level Plant Nutrition Forum Calls for a New Agenda for Plant Nutrition
As the world rushes towards a population of 10 billion people by 2050 while simultaneously facing the perils of climate change, global agricultural systems must evolve to ensure our sustainable future. On November 18th and 19th, the International Fertilizer Association (IFA) convened leading experts from diverse sectors including the research and farming community, international organizations ...

Balancing Act: Reconciling the Laws of Minimum and the Maximum
Does going to the extreme in fertilizer application overcome yield limitations? When it comes to plant development and yield, imbalance is more likely to threaten soil health, production and your pocketbook. Instead, achieving nutrient balance is crucial to crop success. With that in mind, we reflect on the often-perceived conflicting theories – Liebig’s Law of Minimum and ...

Identifying future soil science research needs
Soil is subjected to a growing number of human-caused dangers from contamination, urbanization, desertification, salinization, mismanagement, and erosion. The soil ecosystem provides services necessary to manage and maintain a healthy and stable planet. Soil is key to carbon sequestration, nutrient cycling, water purification, and waste treatment. The Soil Science Society of America (SSSA) has ...

Less agricultural phosphorus could be key to cleaner Baltic Sea
Reducing the amount of phosphorus used in agriculture could go a long way in meeting the Baltic Sea Action Plan (BSAP)1 targets. A Swedish evaluation of measures for reducing agricultural phosphorus suggest phosphorus inputs to the sea could be cut by 180 tonnes per year, or about two-thirds of Sweden's target. The nations surrounding the Baltic Sea have established the BSAP to restore the ...

‘The best ways to increase yields are not necessarily high-tech’
According to Ernst van den Ende and Sjaak Bakker “Whatever the local conditions may be, Wageningen UR can contribute to the sustainable intensification of agriculture anywhere in the world,” says Ernst van den Ende, general director of Wageningen UR Plant Sciences Group. “Our starting point is improving existing systems rather than simply introducing the latest technologies. ...

Tillage and reduced-input rotations affect runoff from agricultural fields
A new study from researchers at the USDA Agricultural Research Service provides information about runoff under different management practices and can help farmers choose the practice that is best for them. No-till management practices can reduce soil erosion, but evidence suggests they can also lead to increased runoff of dissolved phosphorus from soil surfaces. Meanwhile, farmers looking to ...
