Soil sampling for fertilizer application

Benefits of fertilizer is to supply nutrients that are less or even not available in the soil to become available to support plant growth. As we have seen fertilizer are produced and circulated in the market is very diverse, both in terms of type, shape, size, nutrient content and packaging. With the various types of fertilizers with a variety of characters, often create confusion wearer to use them. Not surprisingly, the common failure of crop production as a result of fertilization errors. To overcome this before fertilization there are some things that need to be done, namely soil and leaf analysis, identify symptoms of nutrient deficiencies, and determine the method of fertilization.
Soil and leaf analysis is to determine the availability of nutrients in the soil and nutrients is needed by plants. In addition to identifying the symptoms of damage / abnormalities in the plants we can already predict that less nutrients is needed by plants. To apply the fertilizer according to recommendations from the analysis needs proper fertilization methods, because if not, then provision of fertilizer is not useful

Soil that is used for agriculture, especially cultivation of plants need to get careful attention in order to the cultivation of plants that work well, what plants are suitable, the content of minerals in soil are sufficient or whether there is a lack, or there among the materials contained it contains toxins, soil is too acidic or alkaline so that the plant will die. By utilizing our agricultural technology can perform analysis on the soil for further diagnose what plants are suitable to be developed on soil or in order to provide what nutrients are available and sufficient for the existence of plants that we grow through fertilization. In addition to soil analysis shall be furnished with the analysis of plant tissue is used / intended to diagnose nutrient needs of a plant, all of which will affect crop yields.

Think about why you are sampling the soil. The goal is to estimate the capacity of the soil to provide adequate amounts of the necessary nutrients to meet the needs of the crop (or crops) to be grown. It should be clearly understood that soil testing does not measure the amount of nutrients in the soil. The sample of soil should represent the area it is taken from. A soil sample must be taken at the right time and in the right way. The tools used, area sampled, depth and uniformity of the sample, information provided, and packaging all influence the quality of the sample.
Taking a Good Soil Sample
The way the soil samples are taken is extremely important, as the recommendations you   receive from soil tests will only be as good as the samples you send for analysis.
Collecting the soil Samples
The sample bag:   Use a new soil-sample container, plastic bag or plastic container. Soil-sample bags are available free from Kinsey Agricultural Services.    Zip-loc bags are fine – as long as they have never been used - but put Scotch tape over the writing or attach masking tape to write on because all types of marking ink can rub off the bag during shipment.  Do not use paper sacks from the grocery store, bread wrappers, or such items, due to possible contamination. Avoid using a plastic bucket that has been used for other purposes.   Even repeated washings of a bucket used to mix salt and minerals for feed can still result in contamination of the sample.
