Hydrolyzed fish fertilizer tested in organic vegetable production
A two-year study evaluated an organic fish fertilizer in a squash/collard rotation, and compared its effectiveness to inorganic sources. Although yields were reduced in the crops grown with hydrolyzed fish fertilizer treatments, economic analyses showed that premium prices and potential profits associated with organic products were enough to offset reduced yield. The authors said that the use of hydrolyzed fish fertilizer could be an economically feasible option in organic vegetable production. (2015-03-25)

Is remote sensing the answer to today's agriculture problems?
Today's wheat growers face many economic and environmental challenges, but arguably their greatest challenge is the efficient use of nitrogen-based fertilizer. Growers need to apply nitrogen-based fertilizer in sufficient quantities to achieve the highest possible crop yields without over-applying - a situation that could lead to serious environmental effects. To assist wheat growers, scientists at North Carolina State University recently developed a technique to properly time nitrogen fertilizer applications. The technique? Remote sensing. (2003-01-15)

For asymbiotic growth of arbuscular mycorrhizal fungi, feed them fatty acids
Scientists around the world have been working to grow arbuscular mycorrhizal fungi without their host plants because they can be used as organic fertilizer in agriculture and forestry. AM fungi help plants receive nutrients from the soil through a network that is efficient and far more reaching than their own roots can provide. Shinshu University group successfully demonstrated that AM fungi can be grown asymbiotically when given myristate as a carbon and energy source. (2020-11-09)

Fertilization with high-nitrogen fertilizer for the first 12 months, followed by 12 months of moderate nitrogen landscape palm maintenance fertilizer resulted in the best overall quality. (2010-12-28)

Scientists developed 'smart fertilizer'
Scientists of Siberian Federal University and Krasnoyarsk scientific center of SB RAS developed the 'smart fertilizer.' Researchers combined traditional fertilizer with a biodegradable polymer, which allowed to slow down the process of decomposition and release of a nutrient into the soil. As a result, the use of fertilizers has been improved and the pressures on the environment have been reduced. The results of the study are published in the Journal of Agricultural and Food Chemistry. (2017-09-05)

TVA fertilizer technology used worldwide -- but few new products since 1970s
Most fertilizers used worldwide today were developed from 1950 to 1970 by the Tennessee Valley Authority based in Muscle Shoals. A $41 million investment in fertilizer research returned $57 billion to US agriculture. Public funding for fertilizer development has dropped dramatically since the TVA fertilizer program closed in the 1990s. Research is needed to develop a new generation of energy-efficient fertilizers to help alleviate the food crisis. (2008-08-25)

Nitrogen source determined significant for inflorescence development in Phalaenopsis
Researchers investigated the accumulation and use of fertilizer nitrogen (N) during the vegetative and reproductive growth stages of Phalaenopsis related to inflorescence development. Experiments showed that inflorescence is a major nitrogen sink during the reproductive stage of Phalaenopsis. Fertilizer applied during the reproductive stage was found to be a significant N source for inflorescence development of the orchid, while additional experiments indicated the importance of providing ample N fertilization at all growth stages. (2014-03-26)

Filling intercropping info gap
In some parts of Africa, farmers intercrop sorghum -- a grain -- and peanuts. But they face a major information gap. There hasn't been much research on optimal levels of fertilizer use for intercropping sorghum and peanuts in these areas. A new study has filled this information gap. Researchers from Niger, Mali, and the United States have developed a method to help farmers determine how much fertilizer to apply when intercropping. (2017-11-15)

Organic farming can reverse the agriculture ecosystem from a carbon source to a carbon sink
Lessening GHG emissions tops the agenda of the world's sustainable development research today. Burning crop residues and excessive use of chemical fertilizers results in an enormous waste of biological resources, which further weakens the potential capacity of the agro-ecosystem as a carbon sink. Now researchers showed that replacing chemical fertilizer with organic manure significantly decreased the emission of GHGs. Organic farming can reverse the agriculture ecosystem from a carbon source to a carbon sink. (2015-04-29)
