  • Seeding rate and planting arrangement effects on growth and weed suppression of a legume-oat cover crop for organic vegetable systems

    Winter cover crops can add soil organic matter, improve nutrient cycling, and suppress weeds in organic vegetable systems. A 2-yr study was conducted on organic farms in Salinas and Hollister, CA, to evaluate the effect of seeding rate (SR) and planting arrangement on cover crop density, ground cover, and cover crop and weed dry matter (DM) with a mixed cover crop. The mix contained legumes (35% ...

  • Seeds of change in sub-Saharan Africa

    In the late 1900s, as per-acre grain yields moved to 3 metric tons per hectare in South and Southeast Asia and Latin America, 5 metric tons per hectare in China, and 10 metric tons per hectare in North America, Europe and Japan, there’s one place where production stagnated big time: sub-Saharan Africa, where loss of soil fertility on small farms trapped grain production at an unsustainable ...

  • Emissions from Crops - POST Note

    Agriculture contributes 9% of the UK’s greenhouse-gas (GHG) emissions burden and 10-12% globally. Although there is a long-term declining trend from UK agriculture, the sector may account for a larger share of overall emissions in the future as other sectors reduce emissions. This POSTnote focuses on reducing GHG emissions from growing and storing arable and horticultural crops. ...

  • Crop sensors outdo farmers at choosing nitrogen rates

    Choosing how much nitrogen (N) to put on corn fields isn’t something farmers take lightly. Many factors go into the decision, including past experiences, the timing of application, yield goals, and results from soil tests. Nevertheless, crop sensors can select N rates for corn that outperform those chosen by farmers, according to more than 50 on-farm demonstration projects conducted in ...

  • Comparison of certified and farm-saved seed on yield and quality characteristics of Canola

    Relatively high seed prices and low canola (Brassica napus L.) grain prices created a controversy over using farm-saved seed from hybrids. Agronomic implications of saving seed from a canola crop were investigated by planting certified seed and saved-seed of an open-pollinated and a hybrid canola cultivar at eight site-years in Saskatchewan and Alberta, Canada. In one series of experiments ...

  • How three U.S. mini-farms are sowing the seeds of global food security

    Tiny, biointensive operations show smallholder farmers from around the world how they can grow far more food than conventional approaches. Her face shaded by a wide-brimmed straw hat, Olawumi Benedict is cheerfully tending to her “little babies” — kale seedlings growing in shallow wooden flats until they’re hardy enough for transplantation into soil beds. Three miles over ...

  • Rotary batch blender mixes biological products that boost farm crops

    Agriculture has never been more challenging and fertility efficiency tools, such as inoculants, more important. Modern farmers rely on technology and production practices to significantly increase the yield of their food crops. Biological products like inoculants are a vital part of that strategy. Novozymes Biologicals is an industry leader in developing and manufacturing inoculants, which are a ...

  • Agronomic and economic performance characteristics of conventional and low-external-input cropping systems in the central corn belt

    We conducted a 9-ha field experiment near Boone, IA, to test the hypothesis that yield, weed suppression, and profit characteristics of low-external-input (LEI) cropping systems can match or exceed those of conventional systems. Over a 4-yr period, we compared a conventionally managed 2-yr rotation system {corn (Zea mays L.)/soybean [Glycine max (L.) Merr.]} with two LEI systems: a 3-yr ...

  • Saddle up, soybean seed pigments: argonaute5 in spatially regulated silencing of Chalcone Synthase genes

    Most soybean seeds you see, whether in bins at the store, or in train cars as a commodity crop, have a yellow seed coat that may have only a tiny fleck of dark pigment at the hilum, where the seed attaches to the pod. The predominant yellow color results from silencing of chalcone synthase (CHS) genes by RNA interference (RNAi) due to the presence of I or ii alleles. The ii allele has an inverted ...

  • Can pulse crops play a role in mitigating greenhouse gases from North American agriculture?

    The atmospheric buildup of greenhouse gases (GHGs) is a serious environmental issue. Globally, agricultural activities are an important source of anthropogenic GHGs, contributing 20% of the annual atmospheric increase. Management choices largely determine if agricultural soils will be a source, a sink, or will be neutral with respect to GHG net flux. The proportion of agricultural land that is ...

  • Family farms can be competitive by focusing on conservation and stewardship

    While the U.S. Department of Agriculture (USDA) reports a 40 percent decline in U.S. cropland soil erosion rates from 1982 to 2007, recent trends appear to challenge this progress. Record prices for corn and soybeans have diverted acres out of conservation programs and encouraged intensive production on a wide scale. Tree lines are cleared and wet areas drained, turning 120-acre farms into ...
