Title: Innovations in Nitrogen Measurement by Larry C Purcell
Introduction
Larry C Purcell is an accomplished inventor based in Fayetteville, AR (US). He has made significant contributions to the field of agricultural technology, particularly in the measurement and fertilization of nitrogen levels in non-leguminous crops. With a total of 3 patents to his name, Purcell's work has the potential to enhance crop yield and optimize fertilizer use.
Latest Patents
Purcell's latest patents include a system and method of in-season nitrogen measurement and fertilization of non-leguminous crops from digital image analysis. This innovative approach involves determining leaf nitrogen concentration and yield from a digital photograph of a fully developed leaf, such as those from corn, wheat, rice, cotton, potatoes, sugarcane, turfgrass, or forage grass species. The method utilizes a dark green color index (DGCI) that correlates closely with leaf nitrogen concentration and yield. By incorporating standardized color disks with known DGCI values in the digital photograph, the system allows for corrections based on varying camera types and lighting conditions. This technology aims to determine the appropriate amount of nitrogen fertilizer needed to maximize crop yield potential.
Another notable patent focuses on a system and method of determining nitrogen levels from a digital image. Similar to his previous work, this method processes digital images to ascertain leaf nitrogen concentration and yield. The use of an internal standard, represented by standardized color disks, ensures accuracy in measurements across different conditions.
