When you’re preparing your agricultural land for next produce  it is always advisable to check whether land’s soil is right for it or not? Or if its soil health is good and rich in nutrients for your crops?

The same old traditional methods do not bring you the sufficient data for knowing your soil’s needs for good crop growth, so, for surety, it’s better to try soil testing methods. These tests are more precise for soil health information, and they’re done at any soil testing laboratory.

The purpose of soil testing laboratories is that they use a chemical process to detect the soil's fertility and know which nutrients are needed in the soil for helping crop growth. The results let you know details such as the type of fertilizers that will improve your soil’s functions and their appropriate dose for good crop production, avoiding any financial loss. They can also let you know the pH level of the soil and the categorization between saline, alkaline or mineral soils, which can be advised on how to convert them into normal soils.

Soil testing promotes the use of organic fertilizers and insecticides under recommended doses, preventing their indiscriminate use. It prepares a fertility map over a specific area that will help in a good cropping system over the said area. It helps to create cropping systems that are more economical, identify how much organic carbon is in the soil that will attend the growth of the crops and the availability of nutrients that are based off it, and identifies any deficiencies in elements that could adversely affect crop conditions and its production.

As a result, there are a varied of different soil testing methods to cover every understanding needed to begin work on your soil.

Samples are prepared by force drying the soil for chemical analyses, or by leaving it wet for biochemical analyses. Some of the soil testing methods used by laboratories are as follows:

  • Identifying Texture and Organic Matter, which classifies the soil as Coarse (types of sandy textures), Medium (loamy and silt loam), or Fine (fine clay textures). Then the quantity of organic matter present is identified from the percentage of the dry soil sample.
  • Measurement of Soil pH, which determines the acidic or base levels of the soil.
  • The Phosphorus testing, necessary for plant growth, determines one of the most important elements needed for crop and soil health.
  • Potassium testing, which is reported by parts per million of potassium (ppm)(K).
  • Moisture factor, which is measured by the loss of moisture weight in the sample soil.
  • Water Holding Capacity which determines how much water is retained by the soil after being saturated and drained.
  • The total quantity of Organic Carbon and Nitrogen for determining the plant’s future growth.

As a result, soil testing examines every possible data regarding the soil, making sure all recommendation is given on its use, proper management, any added fertilizers, soil amendments, crop use, etc. This way, future crops that will be planted in your soil will have a better chance of survival and production by providing precise knowledge on the nutrient quantity it has and its requirements for the soil to function better to the advantage of your crops.
