Closer row widths increase plant to plant competition for nutrients and water but also increase sunlight use efficiency. According to former Iowa State University Soybean Extension Specialist Palle Pedersen, current recommendations are to plant rows that are less than 30" apart. This increases light interception and decreases weed competition. [2]
In 1996, Asgrow released the first Roundup Ready Soybean to the market building upon Monsanto's work to create petunia plants tolerant to small amounts of Roundup developed by Robert Fraley in 1985. The first season of sales saw over 1 million acres using the new seed and quickly over 80% of US soybeans were produced with the seed. [6]
Limits between classes are arbitrary as there are few sharp divisions of the soil continuum in nature. Differences in soils are the result of the interaction of many factors: climate, organisms, parent material, relief and time. The soil classification system changes as knowledge grows through soil mapping and research in Canada and elsewhere.
Such maps are typically richer in context and show higher spatial detail, yet are not necessarily more accurate than traditional soil maps. Soil maps produced using (geo)statistical technique can also include an estimate of the model uncertainty. [3] An example of a traditional soil map showing soil mapping units, described soil profiles and ...
A genetically modified soybean is a soybean (Glycine max) that has had DNA introduced into it using genetic engineering techniques. [1]: 5 In 1996, the first genetically modified soybean was introduced to the U.S. by Monsanto. In 2014, 90.7 million hectares of GM soybeans were planted worldwide, making up 82% of the total soybeans cultivation area.
No-till farming (also known as zero tillage or direct drilling) is an agricultural technique for growing crops or pasture without disturbing the soil through tillage.No-till farming decreases the amount of soil erosion tillage causes in certain soils, especially in sandy and dry soils on sloping terrain.
Countries by soybean production in 2020. This is a list of countries by soybean production from 2016 to 2022, based on data from the Food and Agriculture Organization Corporate Statistical Database. [1] The total world production for soybeans in 2022 was 348,856,427 metric tonnes, down 6.4% from 372,853,699 tonnes in 2021. [1]
The EuDASM is a common platform established by Joint Research Centre in Italy of the European Commission and the International Soil Reference and Information Centre(ISRIC) of Wageningen University in The Netherlands to store soil and related maps in digital format and to provide free access to the global community (Researchers, University ...
