Iron deficiency in soil threatens soybean production
An expansion of soybean production into areas where soybean has seldom, if ever, been grown can be problematic for some farmers. Soils having high pH values and large amounts of calcium and/or magnesium carbonate are notoriously iron deficient. Iron deficient soils in the North Central United States are estimated to reduce soy bean production by 12.5 million bushels every year. John Wiersma, a ...

Alfa Chemistry Testing Lab: Fertilizer Testing Service for Agricultural Products & Crops Industry
There are many factors that will influence the production of agricultural products & crops. Among them, fertilizer will largely determine the production output of crops. Fully aware of what underlying problems may exist with fertilizer, Alfa Chemistry Testing Lab, a US-based third-party testing company, announces to provide one-stop fertilizer analysis testing solutions for manufacturers, ...

Four risks of using fertilizer
Fertilizers are increasingly popular because they successfully support plant growth and increase the yield. But what are the dangers of overusing fertilizers? Did you know that too much fertilization might cause “fertilizer burn”? Read below more about the negative effects of using fertilizer without knowing your soil’s nutrient needs. No optimal yield due to under- or ...

Living mulch, organic fertilizer tested on broccoli
Cover crops provide many benefits to agricultural production systems, including soil and nutrient retention, resources and habitat for beneficial organisms, and weed suppression. In regions where short growing seasons can hinder the establishment of productive cover crops between cash crop growing periods, living mulch systems may provide vegetable crop growers with opportunities to establish ...

Many Countries Reaching Diminishing Returns in Fertilizer Use
By Lester R. Brown When German chemist Justus von Liebig demonstrated in 1847 that the major nutrients that plants removed from the soil could be applied in mineral form, he set the stage for the development of the fertilizer industry and a huge jump in world food production a century later. Growth in food production during the nineteenth century came primarily from expanding cultivated area. It ...

Hydrolyzed fish fertilizer tested in organic vegetable production
In the production of organic vegetables, nitrogen is important, yet can be quite costly to manage. Nitrogen management is even more challenging when production practices call for the use of polyethylene mulch combined with fertigation. The authors of a new study published in HortScience have found that hydrolyzed fish fertilizer holds promise as an "economically feasible" nitrogen source for ...

Fertilizer industry grows despite safety concerns
In years past, Brian Moody's efforts to bring economic development to his small Illinois town focused on modest projects: merging an old hardware store whose owner was retiring with another shop to preserve 30 jobs or pointing artists to a vacant downtown building. Now he has a bigger prospect. Cronus Chemicals wants to build a $1.2 billion plant on a nearby cornfield that would manufacture ...

Effects of chemical fertiliser and animal manure on soil health compared
Fertilising crops with cattle manure can lead to better soil quality than when synthetic fertiliser is used, recent research indicates. The use of cattle manure in the study led to greater soil fertility by encouraging higher microbial activity, and the researchers suggest that it could potentially improve soil’s ability to cope with periods of difficult growing conditions. The complex ...

Intensive grassland farming could have deep effects: sequestering significantly less soil carbon
Huge amounts of soil carbon have been discovered up to 1 metre below grassland in a recent UK study. Yet most carbon inventories do not assess soil deeper than 30 cm. Furthermore, this research suggests that intensive management of grassland, involving high rates of fertiliser use and livestock grazing, may deplete carbon at these depths. Globally, soil contains more carbon than all the ...

Fertiliser tax of €0.05–0.27 per kilogram calculated for France as incentive to limit its use
Farmers seeking to make the most of high crop prices may increase the area of land farmed with a valuable crop and also apply more fertiliser. These two changes can have negative environmental effects, such as water pollution caused by nitrogen run-off, biodiversity loss due to land-use change, air pollution from fertiliser and the release of greenhouse gases through changes in land use. In the ...

Fertilization regimen reduces environmental impact of landscape palms
Palms are an important part of the environment in subtropical and warm temperate climates. Palms' aesthetics and small "footprints" make them desirable in a variety of landscapes throughout the southeastern United States. Unfortunately, palms also have some of the highest nutrient requirements of any plants. Timothy Broschat, a scientist from the University of Florida's Fort Lauderdale Research ...
