QC of infant food - robust & efficient analysis of nutrients, additives, and contaminants
Infant formulas and baby food must meet clearly defined nutritional requirements and quality standards. In a free webinar hosted by New Food on May 4, 2022, Dr. Elke Suess from Metrohm AG (IC) presents ion chromatography (IC) as a robust and efficient analytical technique for manufacturers, analytical laboratories, and public authorities to maintain and comply with these standards and ...

Artificial wetlands on farmland help to prevent soil loss and recapture agricultural by-products
Small field wetlands are a simple and effective way to reduce soil erosion and nutrient pollution, recent research suggests. The authors adapted Norwegian designs for the UK environment and created a series of small rectangular lakes on the edges of agricultural fields. After three years, the wetlands had prevented tonnes of soil from leaving the land, and helped alleviate some of the nutrient ...

Analyzing agroforestry management
The evaluation of both nutrient and non-nutrient resource interactions provides information needed to sustainably manage agroforestry systems. Improved diagnosis of appropriate nutrient usage will help increase yields and also reduce financial and environmental costs. To achieve this, a management support system that allows for site-specific evaluation of nutrient-production imbalances is needed. ...

4R Research Fund Awards First Grants
The 4R Research Fund today announced it has awarded $273,500 in grants for five research proposals aimed at identifying the current state of knowledge and existing research gaps regarding fertilizer best management practices. The Fund, supported by the fertilizer industry and other stakeholders, is a science-based research initiative aimed at improving agricultural sustainability by expanding ...

Writing an equation for soil success
Soil isn’t one size fits all. It may look the same under your feet – but under a microscope, that’s a different story. A plant’s roots, tiny bugs – these things can tell one soil from another quite easily. Soil scientists typically measure different aspects of soil — how much air it contains, how well it retains water, heat, and more — to determine if it ...

Method developed to measure solute movement in soils
Scientists from Aarhus University and Aalborg University in Denmark have developed a new method for measuring the movement of solutes in intact soil. Improving on the existing method, the new procedure can be used on intact, undisturbed soil and provides more confident estimates. Movement, or diffusion, of solutes in soils is involved in many processes of agronomical, environmental and technical ...

Improved soil water sensors aid in irrigation management
Agriculture, a large user of water for irrigation, is under pressure to reduce water use. Increased urban population growth has created more competition for limited water supplies. While growers have used soil moisture probes to aid in irrigation management in the past, earlier probes required maintenance or were expensive or inadequate. New electronic sensors have been developed that require ...

Past, present and future of soil sciences
The Soil Science Society of America (SSSA) is reporting the results of a recent survey of trends related to the soil science profession. The results suggest that employment opportunities in soil and related sciences are increasing, and students, academics, and employers have a positive outlook for the future of soil science. Despite these positive findings, the survey identified areas to be ...

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 ...
