Complete Soil Analysis

For sampling, watch the relevant video:

All soil elements are calculated for agronomic purposes in one sample: pH, conductivity, calcium carbonate, organic matter and mechanical composition, nitrogen, phosphorus and potassium (results are given in units), Boron, Copper, Iron, Manganese, Zinc, Calcium, Magnesium, Sodium, Potassium, Na percentage, SAR, active Ca

To choose a crop, we need to know the limitations that each crop places on the soil characteristics. Thus, some crops may require a specific pH range to thrive, and others well-drained soil. This analysis package includes all these basic characteristics such as pH, conductivity, calcium carbonate, organic matter, and mechanical composition.

Soil sampling for submission to chemical laboratories

Required equipment: 

Soil core removal tool
Strong plastic bag, 1 piece
Permanent marker
Suitable sized box
Insulating tape

The usual, simplified practice is as follows: One sample must be taken from every 5 acres. If there are heterogeneities in the slope and/or the soil texture within one acre, then more samples should be taken per acre.

Using the appropriate tool ("carrot" tool or spade or small diameter pipe), we remove approximately 0.3 kg of soil. The depth varies depending on the crop and the type of soil. For vegetables and annuals, 30 cm is a sufficient depth, while for tree crops after 3 years, a depth of 0.60 meters is required. We always take care to carry out the sampling before any fertilization. If there is no cultivation, then the sample is taken from 30 cm.

The removed quantity is placed in a plastic bag. We mark the bag with the permanent marker, writing the senders last name, the date, and the sequential number of the sample (if, for example, it is the third of five samples we will send, we write "3of5" on the bag).
