Sustainable agricultural partnerships
American Business Conferences will be hosting its 4th in the global series of Sustainable Agriculture Summits in San Francisco on 10-11 August. This established forum where incisive and detailed strategies on how to measure and reduce water and carbon impacts throughout the agricultural supply chain is quickly filling up due to the exceptional value building qualities the summit promotes. ...

In organic cover crops, more seeds means fewer weeds
Farmers cultivating organic produce often use winter cover crops to add soil organic matter, improve nutrient cycling and suppress weeds. Now these producers can optimize cover crop use by refining seeding strategies, thanks to work by an Agricultural Research Service (ARS) scientist. In moderate climates, suppressing weeds in winter cover crops is important because weeds that grow throughout ...

Copper-zinc interactions increase toxicity in soils, say researchers
Agricultural soils accumulate trace metals, particularly copper and zinc, as a result of their presence in wastes (sewage biosolids and manures) and fungicides that are applied over long periods of time. Regulations and guidelines for tolerable concentrations of these potentially plant-toxic elements in soils are based on the assumption that the toxic effects of the metals are substantially ...

Grassy field margins enhance soil biodiversity
Grass strips at field margins are almost as valuable as hedgerows in encouraging diversity of soil creatures, according to new research. Six metre wide margin strips increase the number and variety of species such as earthworms, woodlice and beetles, and may act as corridors between isolated habitats. The study analysed the presence of invertebrates of three main feeding types - soil ingesters ...

Soil microorganisms help prevent non-target effects of pesticides
A new study has investigated the properties of different types of soils which can cause pesticides to cling on to soil and prevent them from affecting non-target species. It demonstrates that microorganisms can play an important role in binding pesticides to soil. Microbial levels can therefore help indicate how much pesticide is freely available in soil. Pesticides applied during agricultural ...

New rules for English farmers to prevent nitrate pollution
Many farmers and land managers in Lincolnshire are missing the chance to be better prepared for new Nitrate Pollution Prevention Regulations, with the 14 January free seminar at Market Rasen Racecourse barely half full.

A model to measure soil health in the era of bioenergy
One of the biggest threats to today’s farmlands is the loss of soil organic carbon (SOC) and soil organic matter (SOM) from poor land-management practices. The presence of these materials is essential as they do everything from providing plants with proper nutrients to filtering harmful chemical compounds to the prevention of soil erosion. Sustainable management practices for crop residues are ...

Cassava for food and energy security
The tropical root crop cassava could help protect the food and energy security of poor countries now threatened by soaring food and oil prices, FAO said today. At a global conference held in Gent, Belgium, cassava scientists called for a significant increase in investment in research and development needed to boost farmers’ yields and explore promising industrial uses of cassava, including ...

EU call for regulation of wood ash fertilisers
Wood ash may not be an ideal fertiliser for the forest after all, according to new research, which found high natural levels of toxic trace elements in wood ash. In addition, the study showed that adding wood ash could affect the forest soils in such a way that toxic elements are more rapidly released into the receiving waters. Wood ash is a by-product of wood burning which is classed as a form ...

Cattle contribute to greenhouse gas production in soil
As harmless as cattle may seem, they are regarded as a threat to the climate. Through their digestion they produce the green house gas methane, which they expel continuously. Scientists from the Institute of Soil Ecology of the GSF – National Research Centre for Environment and Health in Neuherberg, Germany and Czech colleagues at the Budwies Academy of Sciences have shown that cattle can boost ...
