  • Yield editor Software for removing errors from crop yield maps

    Yield maps are a key component of precision agriculture, due to their usefulness in both development and evaluation of precision management strategies. The value of these yield maps can be compromised by the fact that raw yield maps contain a variety of inherent errors. Researchers have reported that 10 to 50% of the observations in a given field contain significant errors and should be removed. ...

  • A call to conserve crops’ wild cousins

    Wild cousins aren’t always appreciated at family gatherings. But when it comes to crops, the opposite is often true: Plant breeding has historically relied on genes from plants growing in the wild as a source of diversity that can be introduced into crop plants to produce new crop varieties that are more resilient, nutritious and productive than those currently cultivated. As human ...

  • 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. ...

  • Molecular genetic linkage map for allotetraploid colonial bentgrass

    Interspecific hybridization is a widely used approach to improve crop species. We are pursuing the possibility of using interspecific hybridization between the turfgrass species colonial bentgrass (Agrostis capillaris L.) and creeping bentgrass (A. stolonifera L.) for the improvement of resistance to the fungal disease dollar spot (Sclerotinia homoeocarpa F.T. Bennett) in creeping bentgrass. From ...

  • Insecticide risk map exposes threat to aquatic life

    The global threat that insecticides pose for aquatic biodiversity has been revealed in a recent modelling study that pinpoints areas at greatest risk. The mapping exercise conducted by the researchers reveals that aquatic life in water bodies within 40 per cent of the global land surface is at risk from insecticides running off the ...

  • 9 Maps that explain the World`s Forests

    This post is co-authored with Dave Thau, senior developer advocate for Google Earth Engine, Google's satellite image processing platform. By the time we find out about deforestation, it’s usually too late to take action. Scientists have been studying forests for centuries, chronicling the vital importance of these ...

  • Can genetic engineering help quench crops’ thirst?

    Researchers around the world are exploring how GMO technology might boost food production under hot, dry conditions. Roger Deal is trying to figure out how plants remember drought. An assistant professor of biochemistry and genetics at Emory University, Deal says most plants have a kind of memory for stress. When experiencing water shortage, for example, plants close ...

  • Enriching African soils key to boosting crop yields

    In African countries where farmers have access and can afford to buy fertiliser, there is a profound difference in agricultural yields, a feature in Nature notes. The red soil found across much of the continent is low in organic matter and key nutrients, and intensive farming in ...

  • Profitability maps as an input for site-specific management decision making

    For over a decade, farmers have been collecting site-specific yield data. Many have formed doubts about this investment because of their inability to directly apply this information as feedback for improving management. The objective of this case-study analysis was to investigate how site-specific decisions can be improved by transforming a long-term multiple-crop yield-map dataset into profit ...

  • New FarmLogs hardware device automatically creates Yield Maps

    Today from InfoAg, FarmLogs, the leading all-in-one field monitoring platform and trusted partner to over 25% of U.S. row crop farms, announced the release of FarmLogs Flow, the first connected machine product to generate instant yield maps. The small plug-in hardware device integrates with the FarmLogs platform and automatically creates yield maps, eliminating the complex and manual time ...

  • Optimization of crop canopy sensor placement for measuring nitrogen status in corn

    Active canopy sensors can be used to assess corn (Zea mays L.) N status and direct spatially-variable in-season N application. The goal of this study was to determine optimal sensor spacing for controlling whole- and/or split-boom N application scenarios for a hypothetical 24-row applicator. Sensor readings were collected from 24 consecutive rows at eight cornfields during vegetative growth in ...

  • Corn and soybean mapping in the united states using modis time-series data sets

    Monitoring and mapping of U.S. croplands has long been a primary goal of many users of earth observation satellite data. The advantages of using low spatial and high temporal resolution data are (i) increased ability to monitor the phenological change of crop plants, and (ii) the possibility of generating consistent large area crop cover maps. This study investigates the potential of 500-m MODIS ...

  • Advancements in chemistry are providing growers with flexibility when managing slug pressures in potato crops.

    Flexibility in slug control The mild and wet weather and lack of ground frosts seen this winter, means that being vigilant to slug activity will be key as we move into the potato planting season. Andrew Sprunt, Agrii’s Northern region potato technical agronomist, explains what growers can expect from the season ahead, and how to manage the potential impact at farm level, ...

  • Methods for creating stomatal impressions directly onto archivable slides

    Stomatal density has been shown to be a primary determinant of crop yield, water use efficiency, and limitation to CO2 assimilation rate. Widely used methods of assessing stomatal density sample relatively small regions of the leaf, are labor intensive, or do not yield stable archivable samples for revisiting samples. We describe several methods of producing such epidermal impressions that yield ...

  • Development and characterization of large-scale simple sequence repeats in Jute

    Jute is an important crop of the Indian subcontinent and comprises tossa jute (Corchorus olitorius) and white jute (C. capsularis). The yield and fiber quality of this crop remained stagnant for many years and could not be improved through conventional plant breeding. Also, no effort has been made to develop molecular markers on a scale required for marker-assisted selection (MAS) to supplement ...

  • A decision tool for sustainable agricultural policies: the case of water saving scenarios for Apulia Region (Southern Italy)

    The economy of Apulia Region largely depends on agriculture but the scarce water resources are the main factor threatening the sustainable production of this sector. This paper describes a geographical information system (GIS) based water balance tool that integrates maps of crops, climate and soil parameters with various scenarios of cropping pattern and farming practice changes. The aim is ...

  • Soil water surplus and ENSO events during the last humid period in Argentine Pampean flatlands

    Daily soil water balances are estimated for the period 1951-2006 in the Pampean flatlands. Daily soil water surplus is the major output with their annual trends, being analysed because of their harmful effects on crop harvests and floods. Soil water surplus trends were analysed founding positive trends, although only two stations were statistically significant at probability level of 95%. ...

  • A simple spectral index using reflectance of 735 nm to assess nitrogen status of rice canopy

    Spatial distribution of canopy N status is the primary information needed for precision management of N fertilizer. This study demonstrated the feasibility of a simple spectral index (SI) using the first derivative of canopy reflectance spectrum at 735 nm (dR/d|735) to assess N concentration of rice (Oryza sativa L.) plants, and then validated the applicability of a simplified imaging system ...

  • On-time Pest Protection

    Farming can be a beautiful job under an open sky. But sometimes that ”open sky” determines the flow of farming, total yield, and productivity according to the weather (rain, drought, hail, frost). Since the weather is a major factor in farming, farmers need to manage certain practices to protect their crops from bad weather conditions as well as from various insects and diseases ...
