Delta Smart Systems
What is DSS?
• A precise data-gathering system collected to improve grower profitability
• Records production practices used on the farm
• Uses on-board to capture yield data
• Uses USDA grading standards to measure impact on quality
• Utilizes a large data base Community to analyze data
• Confidential

Delta Smart Systems
What is DSS?
• More than just a database
• Ties together all production data with local weather station data
• Ties together all production data with field observations and samples

Regional Analysis
• Split DSS data into three regions•To customize recommendations
•To provide local solutions• Identify and remove limiting
factors to yield and quality

Plant Analysis
• Tool for in-season use to determine and manage plant nutrient levels and ratios
• Some elements can be corrected in-season with Foliar Applications
![Page 12: 1 Cotton 2005 Ouachita Fertilizer River Parishes.](https://reader030.fdocuments.net/reader030/viewer/2022032313/56649e705503460f94b6ecc2/html5/thumbnails/12.jpg)
12
Value Offering
• Enables growers to identify nutrients that limit yields or quality: improve plant health
• Allows deficiencies or imbalances to be corrected in-season to increase profits.
• Helps avoid the application of excessive rates and unnecessary nutrient applications are avoided.

Disease Protection*
• Balanced nutrients have proven to reduce disease pressure in cotton:• Verticillium
• Pythium, fusarium, root rot and nematodes

Sulfur on Cotton
• Required on sandy soils or soils with low organic matter
• Sulfur deficiencies look much like nitrogen deficiencies, pale-green leaves on the upper part of the plant.
• Sulfur deficiency appears on new growth

Zinc Problems in Cotton
• Laser leveling, high copper, iron and manganese concentrations
• Highly alkaline soils
• Low VAM* levels • Cool wet periods
which affect root movement *VAM-Vascular Microorganisms

Magnesium in Cotton
• Usually associated with low soil pH, especially with very high Mn levels.
• Little yield data available to compare Mg applications in cotton.

DSS in 2004: River Parishes
• Other results:• 130 lbs. N gave the highest yields
• Wet soils can lose N to the air.
• 10 lbs. sulfur increased yields by 162 lbs. of cotton compared to no sulfur
• Plant issue samples were low in zinc and copper

Results from DSS: River Parishes
• Planting on April 15 and April 16 was the optimum planting date.
• Planting at .75 inches deep produced 100 lbs. more cotton than planting at 1.5 inches deep.
• Planting cotton after corn produced 200 lbs. per acre than cotton after cotton. This area provided the highest return for planting cotton after corn.

DSS Summary
• 15,000 acres in 2004• 50 plant tissue samples• 250 field observations• Two satellite weather stations• DSS split LA cotton into three
distinct areas to better understand profitable cotton production

DSS Summary
• Cotton seeding rates performed best at 45,000 seeds per acre in 2004.
• Using weather stations to forecast 25 GDU accumulations the first five days after planting is an effective tool to use as a planting guide.
• We have weather stations running now and can have the information sent to you.
