As the grid sampling is becoming popular, several people have started taking more soil samples with keen interest. This situation brings more queries about soil labs like why these labs are getting distinct results for the same field and same sample, why recommendations for using fertilizer vary from labs to labs. There are countless yet reasonable explanations for these variations.
Soil sample reporting includes two different services-
The initial reason for distinct analytical results is the sorts of chemical extractants used by soil laboratories. On primary stage, it may not seem logical for labs to make use of distinct chemicals to extract same nutrients, but there are special reasons to do the same. A fewer reasons are-
About soil build up
This is a longer term philosophy of fertilizer recommendations. This recommendation is ideal for farmers that own land and want to earn more profits for several years. The main reason or logic behind this approach is that farming will be done in better way and the farmer can avail more yield when all of the roots get abundant supply of nutrients via soil. When the soil levels increased, profits and yield also get increased at faster rate than costs. To make this happen, farmer need to manage the crop in proper way to protect the yield from other factors. Weather is responsible for good or bad yield. So, soil lab tests are important to determine suitable nutrient level requirement that matches the weather condition.
At the end, people will find that they need to make adjustments to lab recommendations as they have unique information that the soil lab cannot find. There are farmers who cannot afford a strong soil buildup program and have rented farming land on yearly basis. There are areas where soil lab recommendations won’t help farmers and thus, the knowledge and experience work well for them.
