Airborne Gut Action Helps Wild Chili Pepper Seeds
2013-06-24 07:25:08

University of Washington Scientists have long known that seeds gobbled by birds and dispersed across the landscape tend to fare better than those that fall near parent plants where seed-hungry predators and pathogens are more concentrated. Now it turns out it might not just be the trip through the air that's important, but also the inches-long trip through the bird. Seeds from a wild chili pepper plant found in South America, after being eaten and passed through the digestive tract...

The journal Weed Technology features a new article documenting the results of field tests of resistant Palmer amaranth in glyphosate-resistant soybean crops in Arkansas. Conducted over a 2-year period, the study showed that deep tillage alone produced an 81 percent reduction in Palmer amaranth emergence. Lawrence, KS (PRWEB) June 21, 2013 Weed Technology – When weeds become resistant to herbicides, the advantage of growing herbicide-resistant crops is lost. Farming practices that limit...

Study maps world regions where crop production rates must be increased Crop yields worldwide are not increasing quickly enough to support estimated global needs in 2050, according to a study published June 19 in the open access journal PLOS ONE by Deepak Ray and colleagues from the Institute on the Environment (IonE) at the University of Minnesota. Previous studies estimate that global agricultural production may need to increase by 60-110% to meet increasing demands and provide food...

Terramera Partners with Hydrex to Help Community Vancouver, BC (PRWEB) June 18, 2013 Terramera, a pioneer in developing effective and safe biopesticide products for pest management, today announced that it partnered with Hydrex Pest Control to provide pest control services for a nonprofit, transitional living center for the homeless, The Kingdom Center (TKC). Alex McCarty, Site Manager for TKC said, “ I was thrilled with the service and the results from the treatment in January. The...

Tillage, Reduced-input Rotations Affect Runoff From Agricultural Fields
2013-06-11 13:55:55

American Society of Agronomy No-till management practices can reduce soil erosion, but evidence suggests they can also lead to increased runoff of dissolved phosphorus from soil surfaces. Meanwhile, farmers looking to avoid herbicides often have to combat weeds with tillage, which causes erosion. With all of the tradeoffs of different management systems, which one should growers use? To answer that question, researchers from the USDA Agricultural Research Service compared nutrient and...

Evolution Fights Back Bioengineered Crops
2013-06-11 09:04:31

April Flowers for redOrbit.com - Your Universe Online Since 1996, farmers across the globe have planted more than a billion acres of genetically modified corn and cotton that have been engineered to produce insecticidal proteins from the bacterium Bacillus thuringiensis, or Bt for short. Organic farmers used Bt proteins in sprays for decades to kill a number of devastating pests because the proteins are considered environmentally friendly and harmless to humans. Some scientists, however,...

Feeding 9 Billion In 2050
2013-06-10 13:15:57

Lee Rannals for redOrbit.com - Your Universe Online A new model report in the journal Nature Climate Change helps solve the problem of world hunger once the Earth's population hits 9 billion by mid-century. Scientists unveiled an all-encompassing modeling system that integrates multiple crop simulations with improved climate change models. The model helps predict global wheat yields while reducing political and socio-economic influences that can skew data and planning effects....

Cash crop
2013-08-05 12:49:51

Cash crop is a term used to reference a profitable crop for farmers. Plants like cotton and tobacco are a few cash crops farmer tend to deal with. These crops do not stay with the farmer for their livestock feed or used in the home, rather, in many cases they are exported; thus creating revenue for the farmer. The price of cash crops is largely based on supply and demand in more developed countries, where the supply is actually coming from lesser developed areas. When a bumper crop, that...

Intercropping
2013-07-31 15:20:47

Intercropping is growing crops of multiple products in a specific area. Using the property for more than one crop serves dual purposes such as adding structural support along with providing needed nutrients as well as weed and pest control. Careful consideration and control is required when intercropping. Considerations such as soil content, the amount of water needed for each crop and the amount of sunlight needed for each crop. An example of intercropping are planting tall crops that...

Seed Drilling
2013-05-18 07:39:11

Seed drilling is a method used by farmers in order to have a more unified, crop-yielding season. The first known use of seed drilling was in 1500 BC by the Sumerian. At this time, they were using a single tube. Later, in the 2nd Century BC, the Chinese developed a multi-tube iron drill. This facilitated in a larger crop planting allowing them to feed their large population. The first recorded patent of a sowing machine was in 1566 by the Venetian Senate, attributing Camillo Torello. In the...

Erosion
2013-04-01 12:48:39

Erosion is the process by which rock and soil are taken from the surface of the Earth by exogenetic processes like wind or the flow of water, and then transported and deposited in another location. While erosion is a natural process, human activities have increased by 10 to 40 times the rate at which erosion is happening globally. Excessive erosion results in problems such as desertification, decreases in agricultural productivity because of land degradation, sedimentation of waterways,...

Dryland Farming
2013-03-15 11:32:48

Dryland farming is farming without the aid of irrigation and only with the amount of rain fall given by Mother Nature. Dryland farming is typical in arid regions such as Southwestern United States, Mexico, the Middle East, and other regions that are known for growing grains. Dryland farming is practiced in all parts of Australia with the exception of the Northern Territory. Process Dryland farming involves the constant assessing of the amount of moisture present or lacking for any given...
