Less nitrogen could increase profit & sustainability
More fertilizer doesn't always mean more profit. That's one conclusion from a 10-year study conducted by Agricultural Research Service (ARS) scientists at the agency’s Soil Plant Nutrient Research Unit in Fort Collins, Colo., and colleagues at Colorado State University. From 1998 to 2008, the researchers evaluated and compared potential management strategies for reducing nitrogen and nitrate ...

Nitrogen Fertilizers And Environmental Problems
Nitrogen fertilizers enable farmers to achieve the high yields that drive modern agriculture. The use of nitrogen fertilizer will continue to increase substantially as global population and food requirements grow. International Fertilizer Industry Association (IFA) forecasts suggest that under current conditions nitrogen fertilizer applications will total nearly 100 million tons per year by ...

Corn colour can tell farmers how much fertilizer to apply
Nitrogen fertilizer is a key ingredient for growing a good corn crop. It is not unusual for a well-fertilized crop to yield more than twice as much as an unfertilized crop. But how much nitrogen should corn producers apply to their crop? Researchers at the University of Missouri help answer this question in a study of how much light is reflected from corn plants reported in the May–June issue of ...

Nitrogen recommendations based on crop reflectance
Nitrogen fertilizer is usually applied in greater quantities to corn than almost any other crop. But when it’s applied in excess of requirements, loss of the excess fertilizer to the environment can contribute to degraded water quality. One of the challenges to making an appropriate nitrogen fertilizer recommendation is the potential variability in soil nitrogen availability that may occur ...

Nitrogen applied
Combating soil erosion is a primary concern for agricultural producers in the United States, and many have incorporated conservation tillage systems in their effort to maintain a profitable crop output. Cover crops are an important tool in this cycle, and while it is known that using nitrogen fertilizers can increase these crops biomass, the resulting levels of nitrogen for the following cash ...

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 ...

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, ...

Nitrogen fertilizers` impact on lawn soils
Nitrogen fertilizers from farm fields often end up in aquatic ecosystems, resulting in water quality problems, such as toxic algae and underwater ‘dead zones’. There are concerns that fertilizers used on lawns may also contribute to these problems. All of the lawns in the United States cover an area almost as large as Florida, making turfgrass our largest ‘crop’ and lawn ...

Arcadia Biosciences Takes Next Step to Enable Farmers to Receive Carbon Credits for Reduced Nitrogen Fertilizer Use
Arcadia Biosciences, Inc., an agricultural technology company focused on developing technologies and products that benefit the environment and human health, today announced that the company has submitted a carbon credit methodology to the Clean Development Mechanism (CDM) of the United Nations Framework Convention on Climate Change. The methodology would allow ...

Experiment demonstrates 110 years of sustainable agriculture
A plot of land on the campus of Auburn University shows that 110 years of sustainable farming practices can produce similar cotton crops to those using other methods. In 1896, Professor J.F. Duggar at the Agricultural and Mechanical College of Alabama (now Auburn University) started an experiment to test his theories that sustainable cotton production was possible on Alabama soils if growers ...

Nitrogen Use Efficient Rice Demonstrates an Average Yield Increase of 30 Percent in Four Years of Field Trials
Four years of field trials with a leading line of Nitrogen Use Efficient (NUE) rice have demonstrated an average 30 percent yield increase over conventional controls. These results were reported jointly today by Arcadia Biosciences, Inc., an agricultural technology company, the International Center for Tropical Agriculture (CIAT) and the African Agricultural Technology Foundation (AATF). CIAT has ...

Rice Farmers in China use Less Fertilizer, Increase Yield
“Rice farmers can decrease their nitrogen fertilizer and pesticide use by around 20%, and increase their yield by 10% by using the ‘three controls technology’ (3CT),” says Dr. Xuhua Zhong, crop physiologist at the Rice Research Institute of the Guangdong Academy of Agricultural Sciences (GDRRI). The meaning of “three controls” is controlling the amount of ...

Love a lush, green lawn?
A lush green lawn is lovely to look at, but too much of a good thing can be bad. Often, that beautiful lawn is the result of regular fertilizing. An abundance of nitrogen and other nutrients in natural waterways can cause trouble for aquatic plant and animal life. High levels of nitrogen and phosphorus can cause an overgrowth of algae in the water, which then blocks light from getting to native ...

A little nitrogen can go a long way
Varying the rate of crop production inputs such as fertilizer and seed makes intuitive sense, as farmers have long observed differences in crop yield in various areas of a single field. The availability of spatial yield information from combines equipped with yield monitors has provided a good resource for improved management. So, optimizing inputs to match yield potential of different areas ...

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 ...

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 ...

Carbon credits to be used to fund GM food crops
US biotech firm Arcadia Biosciences has announced a plan to help fund the planting of genetically modified rice with carbon credits. The company will work with the Chinese government to give farmers who plant their crops carbon credits, which they can then sell on the global carbon trading market. Arcadia is touting its GM rice as a greener alternative to the regular crop. The plant has had a ...

Fertilizer Use to Surpass 200 Million Tonnes in 2018
Global fertilizer use is likely to rise above 200.5 million tonnes in 2018, 25 percent higher than recorded in 2008. World fertilizer consumption will grow by 1.8 percent a year through 2018, according to FAO's new report "World fertilizer trends and outlook to 2018." At the same time "the global capacity of fertilizer products, intermediates and raw materials will increase further," the report ...

Nitrous Fertiliser Prices Remain High Despite Falling Fuel Prices – Liquid Fertilizer Tanks Enable Bulk Buying Savings
Falling fuel prices. International gas prices falling by about 27 per cent compared to last year’s prices. Yet nitrogenous fertilizers continue to remain high, according to Herald Scotland. With gas accounting for around 60 per cent of ammonia’s production costs, AN (ammonium nitrate) and urea values seem to be remaining pretty much the same. Spot crop and milk-farm gate-process ...
