The second step is to remove any roots and vegetation. This can be done by hand or with tools such as shovels, pickaxes, and hoes. It is important to remove all roots and vegetation to ensure that the soil is free of any unwanted materials that may interfere with the growth of crops.
Step 2. Test the Soil
It is important to test the soil before planting to determine the pH level and Nutrient content. This helps to ensure that the soil is suitable for the type of plants that you are growing.
To test the soil on the land, you should collect soil samples and take them to a professional lab where the ph and nutrient levels of the soil can be tested. Also, you will be given the best soil nutrient recommendation that you can apply on the farmland to improve soil nutrients if need be.
To carry out soil testing yourself, you should follow the steps below.
Collect Soil Sample
Collect soil samples from different layers (topsoil, subsoil, and bedrock) from different parts of the field.
Dry and Prepare Soil Sample
Spread the soil samples on a tray and allow them to dry for at least four days. After drying, remove any large stones and other debris.
Grind and Sieve Soil Sample
Grind the dried soil samples to a fine powder using a mortar and pestle. Then, sieve the soil powder using a sieve with a mesh size of 2–3 mm.
Perform Chemical Tests
Perform various chemical tests on the soil sample to determine its pH, nutrient levels, and other properties.
Analyze Results
Analyze the results of the chemical tests to assess the soil’s fertility and to determine if additional soil amendments are necessary. The compatible ph level is within the range of 6.5 to 7.5.
Make Recommendations
Make recommendations for soil amendments, such as fertilizers and/or lime, based on the results of the soil tests.
Step 3. Add Organic Matter
Adding organic matter to the soil helps to improve soil fertility by providing essential nutrients for plant growth. Compost, manure, and other organic materials are all suitable for adding to the soil.
Step 1. Identify Deficient Area
Identify the areas where organic matter needs to be added.
Step 2. Analyze SOil
Analyze the type of soil present on the land to determine if it is suitable for the addition of organic matter.
Step 3. Select Suitable Organic Matter
Decide on the type of organic matter to be added. Compost, manure, green manures, and other organic materials can be used.

Step 4. Till the Soil
Tilling the soil helps to break up any clumps and makes it easier for the roots of plants to penetrate the soil. It also helps to improve drainage and aeration, which are essential for proper plant growth.
Firstly, you need to break up the soil with a spade or shovel. This will loosen the soil and make it easier to till.
After that, you can begin to till the soil. This can be done manually or mechanically. For manual tilling, you can make use of simple farm tools such as spades, hoes, cultivators, shovels, garden Rakes, and forks.
For mechanical tilling, you will need tractors, caterpillars, rototillers, etc.
Till the soil to your desired depth and should be done in a straight line and let the tines turn the soil. Once you complete a row, turn around and repeat the process until the entire area is tilled.
Step 5. Fertilize the Soil
If the soil is lacking in essential nutrients, it is important to fertilize the soil before general-purpose fertilizer that is suitable for the type of plants that you are growing.
Step 1: Test the Soil
Before fertilizing, it is important to understand the soil composition and fertility levels. This can be done by testing the soil with a soil test kit or sending the soil to a local lab.
Step 2: Select the Fertilizer
Once the soil composition is known, select a fertilizer that is tailored to meet the needs of the plants that will be grown.
Step 3: Apply the Fertilizer
Spread the fertilizer evenly over the soil and use a rake to incorporate it into the top few inches of soil.
Step 4: Water the Soil
Water the soil thoroughly to activate the fertilizer and aid in absorption.
Step 5: Monitor the Soil
Monitor the soil over time to ensure that the fertility levels remain balanced and adequate for the plants.
Step 6. Level the Soil
The essence of soil leveling is to even and free the soil of any depressions or bumps. This can be done with a rake or a laser leveler. The goal is to create a flat surface that will allow for even soil preparation and planting.
Step 7. Water the Soil
It is important to water the soil before planting to ensure that it is moist and has enough available water for the plants.
When watering the soil, it should be done evenly using a hose or watering can. Allow the water to penetrate the soil to a depth of 3 to 6 inches. Monitor the soil moisture to ensure it is evenly moist throughout. If the soil is too dry, add more water.
Step 8. Crop Planting
After the first eight steps have been completed, you can go ahead to plant your crop. Make sure you adhere to the planting technique especially the right amount of seeds to be planted in each planting hole.
Also, continue to care for the plant by continuous watering, weeding, and fertilizer/manure application if necessary.
Soil Media Mixture Ratio
Soil media mixture ratio is a combination of different types of soil that are mixed in a specific ratio to create the ideal environment for growing plants. This ratio can vary depending on the type of plant, location, and other factors.
In general, the soil mixture should have a balance of nutrient-rich and nutrient-poor soil, as well as a balance of texture, drainage, and fertility. The mixture should also contain adequate amounts of organic matter, such as compost, to help retain moisture. When choosing a soil media mixture, it is important to select one that is tailored specifically to the type of plant being grown.
