Precision Soil Sampling

Soil sampling is an important step in site-specific crop management as soil variability is often directly correlated to variations in yield. Traditional soil sampling consists of collecting and compositing random samples from across a field resulting in a uniform application of fertilizer and lime. This broad application often leads to an over, or under, application of plant nutrients. Precision soil sampling is accomplished by geo-referencing soil samples from the area which the sample was taken using a Global Positioning System (GPS). This allows growers to manage field variability by optimizing nutrient and lime inputs on a site-specific basis. Precision soil sampling is accomplished through either zone or grid sampling methods.
