1. A Comparison of Point Injected and Knifed Phosphorus for Winter Wheat There are almost 2 million acres of winter wheat grown in South Dakota. Most is produced in the southwest part of the state on residual clay soils in a wheat fallow rotation with only limited, shallow sweep tillage. Very reduced tillage is necessary for wind and water erosion control, and water conservation on the long steep slopes. The continued use of shallow tillage on highly buffered, high pH soils has made broadcast phosphorus fertilizer inefficient in increasing wheat yields, even though phosphorus... Download paper
2. A New Approach for Predicting Soil Nitrate Using Imagery and Non Imagery Information- Model Development and Validation Soil nitrate, a key nutrient for optirnal gowth and development of crop, can be predicted using a new approach based on imagery and non imagery information. This paper presents an algorithm to predict soil nitrate using i~nagery and 11011 imagery infoi-~nation. LANDSAT TM satellite image, topography, soil electi-ical conductivity, crop yield, and soil type have been used to develop prediction models based on atificial intelligence technique called neural network. The models have been developed and... Download paper
