  • Simulating the Effect of Climate Change on Agriculture

    Increased atmospheric CO2 levels and climate change are believed to contribute to extreme weather conditions, which is a major concern for many. And beyond extreme events, global warming is also predicted to affect agriculture.1,2 While climate change is expected to affect agriculture and reduce crop yields, the complete ...

  • 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 ...

  • Prevent harmful conditions from damaging crops with sensor alerts

    Your algae monitoring and control system is all set up, humming along efficiently, and the algae is growing well. Your solenoids are controlling the CO2 input so that your pH is always on target. Coolers (or heaters) are controlling your temperature. Maybe you even have automatic harvesting based on the density of your algae. But what happens if one of the devices breaks down? Pumps, valves, ...

  • 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 ...

  • Stevens Water and US Farm Bill Helps Farmers Optimize Crop Irrigation & Fertilization

    Agriculture is a major element for survival of the human race and of the economic system. 42 percent of the world’s laborers are employed in agriculture, making it by far the most common occupation. With agriculture using approximately 60 percent of available fresh water withdrawals, concerns continue to grow over farmers implementing water conservation practices. Also, increasing contamination ...

  • Active sensor reflectance measurements of corn nitrogen status and yield potential

    Active sensor reflectance assessments of corn (Zea mays L.) canopy N status are advocated to direct variable N applications and improve N use efficiency (NUE). Our goals were to determine: (i) growth stage and (ii) sensor vegetation index with greatest sensitivity in assessing N status and grain yield. Variable crop N was generated by supplying N at different amounts and times in three field ...

  • Strategies to make use of plant sensors-based diagnostic information for nitrogen recommendations

    Improvements of nitrogen use efficiency (NUE) may be achieved through the use of sensing tools for N status determination. Leaf and canopy chlorophyll, as well as leaf polyphenolics concentrations, are characteristics strongly affected by N availability that are often used as a surrogate to direct plant N status estimation. Approaches with near-term operational sensors, handheld and ...

  • Developing Nitrogen fertilizer recommendations for corn using an active sensor

    Producers often overapply N fertilizer to corn (Zea mays L.) because of the uncertainty in predicting the economic optimum nitrogen rate (EONR). Remote sensing represents a potential opportunity to reduce this uncertainty with an in-season assessment of crop N status. This study examines the relationship between EONR and reflectance from a ground-based sensor, and considers its potential for ...

  • Nitrogen recommendations for corn: An on-the-go sensor compared with current recommendation methods

    Precision agriculture technologies provide the capability to spatially vary N fertilizer applied to corn (Zea mays L.), potentially improving N use efficiency. The focus of this study was to evaluate the potential of improving N recommendations based on crop canopy reflectance. Corn was grown at four field sites in each of 2 yr in Centre County, Pennsylvania. Preplant treatments included: zero ...

  • Evaluating multiple indices from a canopy reflectance sensor to estimate corn n requirements

    With the increasing cost of fertilizer N, there is a renewed emphasis on developing new technologies for quantifying in-season N requirements for corn (Zea mays L.). The objectives of this research are (i) to evaluate different vegetative indices derived from an active reflectance sensor in estimating in-season N requirements for corn, and (ii) to consider the influence of the N:Corn price ratio ...

  • Technology that is making plants grow bigger and better

    This article outlines new and improved technology that is enabling growers to increase their yield and output of their crops. The technology includes carbon dioxide (CO2) monitors and controllers, soil moisture sensors, plant based sensors such as sap flow and dendrometers, and nutrient sensors such as EC and TDS sensors. All of the equipment can be automated and data sent to your smart phone or ...

  • AutoTerrain - Worlds best boom stability

    The AutoTerrain works and reacts on both boom movements and twisting forces on the boom. This allows the system to be proactive and react on the cause more than on the symptom. AutoTerrain works with 5 ultrasonic sensors and three gyro sensors. Ultrasonic sensors are located at a given distance on the boom and measure the height of the crops multiple times per second. The gyro sensors measure the ...

  • Ground-based canopy reflectance sensing for variable-rate nitrogen corn fertilization

    Nitrogen available to support corn (Zea mays L.) production can be highly variable within fields. Canopy reflectance sensing for assessing crop N health has been proposed as a technology to base side-dress variable-rate N application. Objectives of this research were to evaluate the use of active-light crop-canopy reflectance sensors for assessing corn N need, and derive the N fertilizer rate ...

  • Treating wastewater as a resource

    A number of UK landfill operators are turning wastewater into a resource by utilising OTT monitoring and control systems to manage the irrigation of Willow crops (for renewable energy generation) with pre-treated effluent. Background Leachate from landfill sites represents a significant potential environmental liability, extending long into the future after a landfill site has ...

  • Measuring CO2 to Optimise the Bulk Storage of Food

    Meeting the food requirements of a growing global population is becoming increasingly difficult. Despite the need for additional food, it is estimated that 50-60% of grain is lost after harvesting, at a cost of about $1 trillion per year.1 One of the major reasons for lost grain is spoilage due to mould or insect infestation during storage.2 To provide a ...
