In farming, soil tests are increasingly being conducted to determine the nutrient content, composition, acidity or pH of the soil. Nutrients in the soil vary with depth, and soil components vary with time.
So depth and time of the soil sample affect the testing results. It is also particularly important to select a tool like the best soil test kit to take a sample.
Analytical data from agricultural samples allow the establishment of effective crop-specific fertilization programs, plant nutrition regulations and, last but not least, land management practices that are efficient, cost-effective and environmentally friendly.
The best soil testers are also tested for primary nutrients such as phosphorus, potassium and nitrogen. In some regions, soils are also tested for other essential nutrients such as calcium, magnesium, and sulfur, as well as elemental contents such as boron, copper, iron, manganese, molybdenum, and zinc.
In case of doubt, the soil is also tested for waste from arsenic, cadmium, nickel, lead, mercury, and selenium.
Nitrogen and potassium, one of the main nutrients in the plant, have a detrimental effect on the environment when applied to the soil in excessive quantities.
Why Are Soil Tests Important?
1. Identify The Needs Of The Plants
Soil testing using the best soil test kits is an important tool for determining the nutritional needs of plants and for environmental assessments.
Some soils have a natural shortage of plant nutrients. Some soils have lost their nutritional properties over time, although in the past they have had sufficient nutritional properties. Soil research is being conducted extensively in crop production areas around the world to understand the needs of plant fertilization.
2. Waste Application
Deep soil tests are performed with the best soil testers to determine the extent of application of waste containing nutrients or other elements that may be harmful to the environment. Waste materials such as animal manure and industrial by-products may contain various plant nutrients.
However, such substances released into the soil at high speed are detrimental to the plant, animal or human health. Several regulations have been adopted to assess the levels of environmental damage to certain chemicals and to limit their use. At the same time, these provisions require soil testing.
3. Solutions For Soil Treatment
Soil analysis is a decisive factor in making the right decisions about land cultivation and plant treatment. Only by using the best soil test kits you will have an accurate analytical data from soil analyses.
They will allow precise determination of the necessary agrotechnical measures such as soil tillage, fertilization, irrigation, drainage, the introduction of improvers and plant protection products.
The detailed information from the soil analysis allows timely detection and prevention of potential soil problems – nutritional deficiencies, structural changes, imbalance of micro- and macro elements, determination of the presence of harmful substances above the limit values, soil zones with lower indicators, leading to poor harvest quality, etc.
Soil Test Indicators
It is a routine practice for many farmers to prefer to import the same chemical fertilizers that they have already used many times in previous years.
If this is done without understanding the mechanism for maintaining soil fertility, the result is only spending a lot of money on complex fertilizers without any need. The best soil test kits will help you determine the composition of the soil and what is or is not needed to improve its performance. So what is soil testing?
1. Agrochemical Soil Analysis
November, December, January, and February are the most appropriate months of soil sampling, provided that no chemical or organic matter is harvested during the preceding three months. Analysis of samples from such soils most closely indicates the degree of need for lime and potassium soils for the coming production season.
2. Soil pH (Acidity)
The results of the soil agrochemical analysis provide information on the amount of time required to be imported, or that there is no such need. If required – the filling of the lime content in the soil should be done as soon as possible.
In areas with heavy rainfall, lime stocks in the soil can be quickly depleted. If the soil is too acidic, it blocks access to other nutrients and traces elements, especially nitrogen and phosphorus. Studies have shown that urea can be dispersed a week after cooking without any loss of nitrogen in the atmosphere.
3. Phosphorus (P)
If the results of the soil analysis show phosphorus content at an index level of 3 or higher, the additional introduction of phosphorous will not be of great benefit for the future harvest. Buying unnecessary compound fertilizers and applying them is just a waste of money and causes changes in groundwater quality.
Liquid manure or other organic fertilizers containing phosphorus can be added to the soil. This way the optimum level of phosphorus content will be achieved.
4. Potassium (K)
Potassium is crucial for the absorption of nitrogen and other nutrients by the plant root system. Its pasture content, with regular hay mowing, can be reduced quite quickly over time.
The problem of element deficiency can be quickly resolved by fertilizing the soil with manure. As a last resort, indicators of optimal potassium content in such land can be improved with chemical fertilizers.
5. Balancing Nutrients
All the above steps to replenish nutrients in the soil are important to maintain nutrient balance. It is important to know that, as a rule, the lack of one nutrient in the soil impedes the absorption of another.
Therefore, no matter how much nitrogen will be introduced into the soil further, this will not be a guarantee for its effective absorption from future harvest, if potassium is not available. Therefore, determining the composition of soils by the best soil testers is not only important but also necessary.
Benefits Of Using The Best Soil Test Kit
Analyzing representative soil samples gives you information on the chemical and physical composition of the soil. It can be used to optimize plant nutrition or to solve soil problems. We have selected three of the main reasons that make the use of the best soil test kits an extremely important part of the field and crop care.
1. A Fertilizer Decision Maker
The results of soil analyses can serve as a guide for deciding whether to fertilize, how much to fertilize, when to fertilize and what to fertilize. With soil analysis results, you can easily select the right fertilizer product for each block.
The results of the best soil testers are a useful tool in making good management decisions, which in turn not only bring economic benefits to the farm but also have a positive impact on the environment.
2. Focusing Attention On A Specific Soil Problem
The results of soil analysis can reveal and draw attention to soil problems in your farm, such as salinization, excessively acidic or alkaline soil reactions, problems arising from the mechanical composition, nutrient levels, significantly deviating from the optimum, etc.
The best soil test kits are a major source of information needed for good soil management as a major and indispensable resource on your farm.
3. Accumulation Of Data As Tracking Changes In The Field
Also, the accumulation of data from analyzes over the years allows you to track changes that occur in soil properties and to identify unfavorable ones in the early stages when the cost of soil recovery is significantly lower.
Soil protection requires a comprehensive approach and consistent action. This can be ensured through continuous monitoring by you. The protection and preservation of soil for future generations is essential to your skills, knowledge, and actions.
The Very Important Ph Of The Soil
When we talk about the best soil test kits, we have to mention that one of their mandatory characteristics is their ability to measure Ph of the soil. Why is this so important?
1. What Is pH?
The acid-base balance is determined by the pH values, the scale varying from 0 to 14. 7 is the neutral pH value. The lower values are considered acidic and the higher values are alkaline. Soils typically range from very acidic at pH 3 to very alkaline at pH 10.
The pH range is determined by many factors, including the basic material constituting the soil and the amount of annual rainfall in the area. Most cultivated plants grow in poorly acidic conditions with a pH of about 6.5. Some plants, such as blueberries, Azealia, rhododendron, and gardenia, require a very acidic environment of 4.5 to 5.5.
2. How Does pH Affect?
Soil pH level has an indirect but significant effect on plant development. The availability of nutrients to the plant is determined by the level of acid-base balance of the soil. Most plants grow in slightly acidic soil because the pH provides good access to all the nutrients.
Soil pH also affects soil-dwelling organisms, whose well-being, in turn, affects soil conditions and plant health. The slightly acidic environment preferred by most plants is also suitable for earthworms, as well as microorganisms that convert nitrogen into a plant-accessible form.
3. How Is pH Adjusted?
Before changing the pH level of the soil, you must correctly read the current soil level. This will determine exactly how much you need to raise and lower the level. You can do this yourself using the best soil testers or in the laboratory.
You also need to know the texture of your soil: clay, sand or something else, because different soils require different amounts of material to change the level.
Usually, sulfur is used to lower the soil level, and lime is used to raise the pH. Limestone is relatively pure calcium carbonate, but it is better to use dolomite limestone because it contains magnesium and raises the level more. Lowering the pH level with the earth’s sulfur is easier than raising it.
4. Why Should You Monitor Soil pH?
Maintaining the right pH is a constant task, especially in naturally acidic soils or in places where rainfall takes away calcium or other alkaline elements.
Fertilizers affect the pH level of the nutrient solution and hence the soil. For this, you often need to monitor the acid-base balance to make sure that it is within acceptable limits.
Soil Sampling Program
Soil sampling using testers is the first step in helping farmers to properly and adequately fertilize the crop. The results obtained, in combination with a good fertilizer recommendation, would help farmers to achieve the desired yields and quality objectives.
A clear and meaningful interpretation of the soil analysis requires proper sampling. This is precisely the importance of selecting and using the best soil testers. Incorrect sampling results in increased errors in the results obtained. So what is the best program for soil sampling?
1. Types Of Soil Samples
Depending on the purpose of sampling/fertilization recommendation, the need for liming, suitability assessment, contamination analysis, etc. soil samples and indicators to be analyzed vary widely.
2. Sampling Scheme
The sampling scheme must fully comply with the local characteristics of the terrain and soil cover. Therefore, the sampling scheme is constructed in advance by a soil expert and is followed in the field sampling.
3. Number Of Soil Samples
With a well-established sampling scheme, an optimal number of soil samples is formed and the accuracy of the result is guaranteed, saving the farmer unnecessary costs for analyzing a large number of additional soil samples.
4. Depth Of Sampling
Depending on the type of culture grown, the sampling depth also varies. The depth of soil sampling must correspond to the depth at which the largest percentage of the root system of the plant develops and where the most effective nutrition and nutrient uptake is carried out.
5. Sampling Period
The soil sampling period must be fully consistent with the purpose of sampling. If samples are taken to determine the fertilizer rate for crop nutrition, priority should be given to areas with reduced growth. If pre-sowing and / or stocking fertilizer is sampled, sampling shall be carried out as close as possible to the sowing period itself.
6. Frequency Of Soil Sampling
The frequency of soil sampling depends on the condition of the crops. As a rule, soil samples are taken at least once a year before sowing/planting and once before key phases of crop development occur.
7. Method Of Sampling
The method of sampling and the use of testers also guarantees the accuracy of the results. The type of soil sample and the indicators for which it will be analyzed defines the method of testing. There are various types of samples.
The most important are the average samples. They are formed by several single samples following the scheme drawn up. When we look for specific physical soil indicators we take single samples. And when we examine the soil characteristics in-depth we take the so called soil samples by horizons.
8. The Proper Reading Of The Results And Accuracy Of The Recommendation
For the correct reading of the results of the soil analyzes, it is not enough to interpret the figures/values of the analysis itself. Failure to take local characteristics into account, such as environmental parameters, soil characteristics, type of precursor and current crop, yield, etc., will result in inaccuracy.
Soil testing is a vital part of agriculture and horticulture management. The best soil test kits are specifically designed to help a farmer, producer or specialist to provide rapid soil analysis on-site. Their scope covers basic needs such as pH, lime and NPK testing, as well as sophisticated soil management kits for measuring a wide range of trace elements.

Accuracy is a must-have feature of the best soil testers. If you choose one, it will become a great utility that is also very user-friendly. Also important is the fact that most of the test kits are made using a special technology that increases the accuracy of their results at home.
2. Which Soil Ph Tester Is The Best?
The main property of the soil is its fertility – its ability to provide nutrients, water, air and heat to the plants. In this sense, the best soil tester is a device that measures not only humidity but also several other important soil indicators such as moisture, salinity, conductivity, illumination and more.
When choosing the best soil test kit for you, also consider the weight of the device, its design, and portability. Working with the tester should be easy for you and the results easy to analyze.
3. How Do You Use A 3 In 1 Soil Tester?
Plants need good soil, moisture, and light. You can measure all these values with the best soil testers and see if the plants have enough water and light and whether the soil is suitable for them.
To set the soil moisture switch to MOIST mode: Place the electrodes in the soil. Read the central scale readings and compare them with the optimal plant-specific humidity in the table.
To measure light, switch to LIGHT mode: Hold the tester with a directional light sensor to the light source to which the plants are normally exposed. Read the reading on the scale above. The two numbers in the table show the minimum and maximum of light specific to your plants.
To measure soil acidity – switch to PH mode: Place electrodes in soil. Read the result from the bottom scale. A value of 8 corresponds to alkaline soil and a value of 3.5 corresponds to acidic soil. The optimum pH for most plants ranges from neutral (pH = 7) to slightly acidic (pH = 6.5). If your soil is too acidic, add natural soil, if too alkaline, add fertilizer.
4. What Is A Good Soil Tester?
The best soil testers are those that are versatile or multifunctional. They measure all the important soil characteristics that tell you what to do next to grow your plants well.
The three most important characteristics that a good soil tester should measure are humidity, acidity/alkalinity, and brightness. Once you have established their values, you will know whether you need to water your plants, add fertilizers, or move them to a lighter / darker place.
