Farmer Phosphorus Plots
2023-2028. CAP will carry out a study to evaluate the agronomic and economic impacts of phosphorus applications to 3 different soil test levels and ranges of phosphorus, through the course of 5 years. Fact Sheet link
Struvite as a Phosphorus Fertilizer Source
2023-2027. The proposed project aims to investigate nonpoint source pollution concerns associated with phosphorus (P) losses in the Western Lake Erie Basin. Specifically, it will evaluate struvite as a slow-release source of P that may minimize P losses through surface runoff and subsurface drainage while maintaining and/or improving crop yields, as compared to commercially-available P fertilizers. If the assessment of struvite as a P source provides evidence that crop production can be sustained at rates lower than are currently recommended for conventional P fertilizer, adoption of this technology will result in direct reduction in P inputs to agroecosystems and consequent reduction of environmental losses of P.
Soil and Crop Biology Testing – What it Means – Why Do It
2023 - ongoing. By using biological testing, farmers are able to better understand what fertility practices are needed for profitable crop production while limiting nutrient runoff. Biological testing can be used to better understand the soil’s capacity for nutrient cycling and availability to the growing crop.
Yield Monitor and Global Positioning Systems
Forty-five farms are now equipped with yield monitors and global positioning systems. These farms generated data with over 960 acres in 28 demonstrations during 2000 and 48 demonstrations in 2001.
This program was initiated to help farmers learn how to get accurate information with the technology. Plot work was based on conservation tillage practices that have potential to improve soil structure and faming income. To build a database of information, practices were limited to nitrogen rates, sub tillage, strip tillage and residue management techniques and tools.
Conducting Randomized Replicated Demonstration Plots
To ensure that information from field plots is accurate, randomized replicated plots are encouraged. This gives each practice exposure to all the variabilities in the field. Including four replications of a practice within the plot eliminates the effect variables that cannot be removed have on yield. Differences in yield can then be attributed to the chief cause with this procedure.
Sub Tillage and Residue Management Program
Six Soil and Water Districts were assisted in acquiring residue management tools. These tools produced data from 25 sub tillage demonstrations on over 500 acres and 10 residue management tool demonstrations on over 100 acres. Compaction tests were conducted on these farms to measure the effectiveness in removing dense layers and in keeping layers from recurring.
Strip Tillage Demonstrations
Three local dealers participated in the strip tillage demonstration program. From these tools, 10 demonstrations on over 200 acres were conducted in 2000 and 2001. The main information gained is the need for having the equipment properly set up to remove the correct amount of residue and to create mound height to benefit spring planting.
Farmer Cluster Program
Seven clusters of farmers sharing equipment, demonstrating new technique, holding meetings to share information will be started Spring 2002. The purpose is to add to the field information generated by the yield monitors, residue management and strip tillage programs, to assist farmer groups in conducting plots that will generate accurate data.
Field Scouting Program
A program of scouting every field in the program was initiated to monitor possible causes of yield difference. Variability abounds in fields where several soil types are present, where ditches have been cleaned and the spoil concentrated in the field; where applications have been improperly made, where inadvertent omissions and commissions were made; where drainage, insects, diseases, and weeds adversely affect yield. This unique feature of CAP field demonstration efforts is proving very worthwhile to farmers growing the crop and local dealers making applications.
To help in the aid farmers with the introduction of conservation tillage. CAP acquired two 30 foot sprayer. These sprayers were housed at local SWCD’s and were available for farmers to spray burn down chemicals to help eliminate spring tillage work.
