Usando un medidor de clorofila para mejorar la gestión de N This NebGuide describes how to use a chlorophyll meter as a tool to improve nitrogen management by detecting nitrogen deficiency and determining the need for additional N fertilizer. Fertilizer nitrogen (N) is increasingly recognized as the source of nitrate contamination in much of Nebraska’s…

Clorofila en Maíz The Early-Season Chlorophyll Meter Test for Corn (Agronomy Facts 53) The chlorophyll meter is a portable, hand-held device that instantaneously measures the greenness (or chlorophyll content) of a plant in the field. Nitrogen (N) is closely associated with leaf chlorophyll; thus chlorophyll meter readings of corn leaves reveal the N status of…

Using a Chlorophyll Meter to Make Nitrogen Recommendations on Wheat Efficient use of nitrogen (N) fertilizer is important to economical wheat production and to the quality of ground and surface waters. Insufficient N results in reduced wheat yield and reduced profit, compared to a properly fertilized wheat crop. However, excessive N produces wheat plants that…

La Importancia de Medir la Clorofila por Kosmos Scientific La clorofila absorbe la luz del sol y usa esa energía para sintetizar carbohidratos del CO2 y el agua. Este proceso se conoce como fotosíntesis y es la base para el proceso vital de las plantas. El Nitrógeno (N) es un elemento clave en la molécula de…
