Fertilizer placement affects nutrient leaching patterns
Controlled-release fertilizers (CRFs) are a widely used method of delivering nutrients to nursery container crops. The fertilizers contain encapsulated solid mineral nutrients that dissolve slowly in water, and are then released into substrates over an extended period of time. Although the use of CRFs is an accepted practice, growers and researchers are always looking for ways to decrease ...

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 ...

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 ...

Study probes sources of Mississippi river phosphorus
In their eagerness to cut nitrogen and phosphorus pollution in the Mississippi River and Gulf of Mexico, people have often sought simple explanations for the problem: too many large animal operations, for instance, or farmers who apply too much fertilizer, which then flows into waterways. But according to new modeling research that examined phosphorus loading from all 1768 counties in the ...

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 ...

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 ...
