Variable–rate, Spinner–disc Fertilizer Applicator
The popularity of spinner spreaders for application of granular fertilizers and agricultural lime, along with increased interests in variable–rate technology (VRT), has raised concern about application accuracy and distribution of these spreaders. This investigation was undertaken to assess the application distribution of a VRT spinner fertilizer spreader. Application distribution was assessed ...
متن کاملChallenges for Making Intensive Soil Sampling and Vrt Pay
Soil fertility evaluation and management can be greatly improved with the use of precision agriculture technologies. Differential global positioning systems @GPS), yield monitors, various forms of remote sensing, geographical information system (GIs) computer software, and variable rate technologies are available for use to producers. Intensive soil sampling, crop scouting, and other practices ...
متن کاملPattern Assessment of a Spinner Disc Variable-Rate Fertilizer Applicator
Previous work by Fulton et al. (2000) showed the development of a program for generating an “As Applied” map to assess uniform and variable-rate application of potash. The “As Applied” map was created using an “As Applied” file generated during field operation in conjunction with different application patterns determined by Fulton et al. (1999). While modifications are required to improve the p...

et al., 1982; Webster et al., 1986). Nitrogen balance research in agricultural production systems continues Fertilizer N recovery in crop production systems seldom exceeds to focus on NO3–N leaching (Jokela and Randall, 1989; 50%. Two long-term winter wheat (Triticum aestivum L.) experiments were selected for use of 15N to evaluate fertilizer recovery in Olson and Swallow, 1984). However, littl...
متن کاملKISAN: An Expert System for Soil Nutrient Management
This paper describes the suitability of application of expert system technology in agriculture and propose the development of a rule-based expert system, named KISAN, for the nutrients management of he soil. The proposed system uses the knowledge of visual deficiency symptoms, evident in the plants, to diagnose the nutrients deficiency/excess in the soil. This system has been developed in the B...
