Abstract
A method of determining the most efficient timing for application of nitrogen to growing cotton plants, wherein the method has the following steps: a) Collecting cotton tissue samples from the cotton field, b) Extracting sap from the cotton tissue samples within 24 hours of sample collection, and c) Analyzing the sap within a short time of extraction, by measuring the nitrate nitrogen levels of cotton leaf sap using an ion specific electrode measuring device.
Claims25
A method of determining the most efficient timing for application of nitrogen to growing cotton plants, wherein the method comprises:
- a. collecting cotton tissue samples from the cotton field,
- b. extracting sap from the cotton tissue samples within 24 hours of sample collection, and
- c. analyzing the sap within 24 hours of extraction, by measuring the nitrate nitrogen levels of cotton leaf sap using an ion specific electrode measuring device.
A method of determining the most efficient timing for application of potassium to growing cotton plants, wherein the method comprises:
- a. measuring the potassium levels of cotton leaf sap using an ion specific electrode measuring device, and
- b. applying a potassium-containing fertilizer at pre-set trigger points.
A method of determining the most efficient timing for application of both potassium and nitrogen to growing plants, wherein the method comprises:
- a. measuring the potassium and nitrogen levels of cotton leaf sap using an ion specific measuring device, and
- b. applying a combination of potassium- and nitrogen-containing fertilizer at pre-set trigger points, wherein said nitrogen fertilizer is derived at least in part from urea-formaldehyde solutions.
