Copper sulphate has been used in agriculture since the 1800s, at least. It is widely used as a fungicide on organic and conventional crops, and it is also used as foliar fertiliser. A study from the Federal University of Vicosa in Brazil has...

Grasslands in large parts of the world are getting little if any fertiliser, which is leading to soil exhaustion. Farmers will have to apply four times as much phosphorus fertilisation in 2050 in order to make the soil fertile again. Only then...

Helping farmers around the globe apply more-precise amounts of nitrogen-based fertiliser can help combat climate change. These fertilisers spur greenhouse gas emissions by stimulating microbes in the soil to produce more nitrous oxide. Nitrous...

As carbon dioxide levels rise, grains and legumes will become significantly less nutritious than they are today. Researchers from eight institutions in Australia, Israel, Japan and the United States found that these crops will have significantly...

Predicting crop yields based on climate, planting and other variables can help regions optimize their limited resources. Farmers are used to optimizing crop production on their own lands. They do soil tests to choose the right amount of...

Drinking water with a relatively high concentration of magnesium protects against hip fractures, according to results of a study from the Norwegian Institute of Public Health . There are considerable variations in the quality of drinking water...

Finding a way to improve nitrogen uptake in crops could improve yields and decrease risks to environmental and human health. Nitrogen is primarily taken up from the soil by the roots and assimilated by the plant to become part of DNA, proteins,...

Nitrogen could be too much of a good thing for the world's grasslands, according to study findings published online by the journal Nature. The worldwide study shows that, on average, additional nitrogen will increase the amount of grass that...

Nitrogen fertiliser applied to crops lingers in the soil and leaks out as nitrate for decades towards groundwater. "Much longer than previously thought", scientists at the Université Pierre et Marie Currie in Paris (France) and at...

In small, bump-like nodules on roots in crops like soybeans and alfalfa, rhizobia bacteria produce the nitrogen that plants need to grow green and healthy. Scientists have wondered for years exactly how this mutually beneficial relationship...

Spraying the appropriate surfactant over potato ridges just before emergence reduces common potato scab in dry years. Application of the right soil surfactant leads to a higher content of soil water in the ridges during periods of drought and...

Aardappelen op zandgrond hebben in een droog jaar minder last van gewone schurft, als de ruggen kort voor opkomst met de juiste uitvloeier worden bespoten. Bovendien kan grondbehandeling met een uitvloeier in droge jaren de knolopbrengst flink...

Nitrogen is an ubiquitous small-molecule gas that can be transformed into the agricultural fertiliser ammonia. Plants perform the chemical reduction of atmospheric nitrogen to ammonia as a matter of course, but for humans to do that in an...

Potato is the fourth food crop in the world, after maize (corn), rice and wheat. In terms of human consumption, potato is even the third most important food crop. Worldwide researchers examine new and old methods to improve nitrogen and phosphorus...

Spraying seed potatoes before planting with phosphate improves early growth of the potato crop. So it appears from preliminary field trials conducted on Dutch soils low in phosphorus. The experimental phosphate formulation is atomized at a dose of...

Aardappelen met een grote fosfaatreserve groeien sneller dan fosfaatarme poters. Een hoog fosfaatgehalte in de knollen biedt bovendien kansen om op de fosfaatbemesting te besparen, zo blijkt uit een bureaustudie die binnenkort in de Plant...

Enriching crops by adding selenium to fertilisers could potentially help to reduce disease and premature death in the African country of Malawi, University of Nottingham researchers say. An international study led by academics at this British...

American and Chinese researchers have found that citrus trees attacked by the Huanglongbing disease (HLB) are suffering from severe phosphorus deficiency. Application of phosphorus solutions to the diseased trees significantly alleviates HLB...

Carbon mineralization is a better predictor of maize agronomic performance than pre-sidress nitrate test and leaf chlorophyll. So it appears from a study conducted by Steve Culman , a researcher at the W.K. Kellogg Biological Station that is...

Treated wastewater solids called biosolids are sometimes used by farmers to boost soil nutrient levels. Now research by U.S. Department of Agriculture (USDA) agronomist Eton Codling provides new information about how long those plant...

Dietary changes since the early 1960s have fueled a sharp increase in the amount of mined phosphorus used to produce the food consumed by the average person over the course of a year, according to a new study led by researchers at McGill...
