  • Estimating Peanut Harvest Losses

    Losses during peanut harvest are common and can be caused by improper setup, operation and/or performance of the harvest equipment. Some losses can also be attributed to the field and crop conditions at harvest. Excessive losses can significantly reduce peanut yields and profits if not managed or reduced during harvest. While harvest losses cannot be…

  • Liquid applicators are commonly used to apply different fertilizer solutions and similar to the sprayers, they need to be calibrated properly to apply the desired application rate in gallons per acre (GPA). While the calibration process for liquid fertilizer applicators is similar to the sprayers, the actual rate for the fertilizer can vary greatly from…

  • Broadcast spinner spreaders are one of the most common and widely used application equipment for lime and granular fertilizer. The importance of proper spreader calibration for accurate fertilizer applications has been emphasized many times and it is always good to see growers putting the time and effort into performing a calibration on their spreaders. However,…

  • Variable-Rate Liming Pays for Itself

    Soil pH variability in agricultural fields is common and needs to be addressed properly to avoid any consequences of low or high soil pH issues later in the growing season. One of the basic precision agriculture practices to address this variability is variable-rate (VR) lime applications. Precision soil sampling – grid or zone – is…

  • Variable-rate application of lime and fertilizer is a common practice to address soil nutrient variability within the agricultural fields. When it comes to precision soil sampling to determine site-specific nutrient requirements, grid sampling still remains one of the most widely used methods due to its ease of implementation and not requiring any additional data layers.…

  • With cotton harvest approaching, growers need to start performing necessary maintenance and adjustments to get the cotton pickers ready. One of the most often overlooked areas during this preparation is harvest technology i.e. the yield monitoring components. As cotton yield data is increasingly being used by crop consultants and growers in making crop management decisions,…

  • Until now, drones have been primarily used for crop monitoring – especially scouting – in agriculture. However, with recent advancements in aerial application technology and the weather challenges limiting timely pesticide applications with ground equipment, the use of drones for spraying pesticides is gaining significant interest in the United States. While spray drones offer several…

  • Mobile Apps for Spray Nozzle Selection

    When it comes to following the best management practices for effective pesticide applications, proper nozzle selection – correct nozzle size and type – is among the top of the list. While almost every nozzle and sprayer manufacturer today have a detailed nozzle selection guide available as both printed and digital (pdf) format, the process in…
