The ratio of the nutrients (nitrogen, phosphor, potassium, magnesium….) within the soil must be known in order to get full productivity in the regions, where we shall make sowing and planting. Most importantly, we must know which nutrients are needed by the plant, which we shall plant, and learn whether these nutrients are present or not within our soil.
The facts such as whether the nutrient values within our soil are suitable for the plant to be planted or not, if it is deficient, how much is lacking are determined in the analysis reports.
Fertilization calendar and amount are determined correctly according to the results.
We must have the samples taken from our soil analysed in compliance with the rules and at the reliable laboratories correctly, in order to obtain good results from the soil analysis.
How the Sample of Soil Analysis is Taken for Walnut Garden;
Soil analysis is conducted with the soil samples, which we shall take from 10 points separately from 30-60-90 cm depths by walking around the land, where we shall establish walnut or almond garden, making zigzags. Soil is collected in the following order:
1. First, the surface of the soil is cleaned when soil sample is being taken.
2. At (10) different points;
a. 10 samples taken from a depth of 0-30 cm are mixed, and the first sample of 2 kg is obtained.
b. 10 samples taken from a depth of 30-60 cm are mixed, and the second sample of 2 kg is obtained.
c. Samples are taken from the depths of 90 and 120 cm, if deemed necessary.
3. The soil obtained is bagged.
4. Information such as name, surname, and where the sample is taken from are written on a paper and placed into the bag.
5. These samples are sent to the laboratory.
These samples are analysed through physical and chemical methods in the laboratory environment and the amounts of nutrients within it are found. Thus, the matters such as which fertilizers must be given when, in which form, and in which amount for the growth of the plant within the sampled soil and in order to yield high are revealed. Soil tests show which nutrient is lacking and which nutrient is high within the soil.
