Before you add fertilizer to your soil, it is important to know what your TDS and pH levels are. Once you know what your soil lacks, you will also know what you need to add to it to make it as healthy as possible. A high-quality soil tester will be able to provide you with the specific qualities of your soil so that you can pick the best fertilizer for your plants.
A high-quality test kit will also be able to tell you what plants will grow the best in the soil that you have. Depending on your climate, your soil and location may best geared for very specific plants. A test kit will help you figure the best plants for your area so that you don’t use the wrong plants and have massive crop failure.
Another thing a soil test kit will help you avoid is over-fertilization. By over-fertilizing your plants, you will make your crops grow too fast which leaves them open to diseases. A soil test kit will help you avoid several issues so it is important to test regularly and for the correct things.
What do soil testers test for?
When you are testing your soil, you will need to know what things that you need to keep an eye on. The most common thing to test for is soil pH. By knowing your soil pH, you can then get the optimum amount of nutrients for your plants.
Your pH levels should measure between one and fourteen with a neutral pH coming in at seven. If the level is under seven, then you have soil that is acidic. Everything above seven will be alkaline soil. Soil that is too acidic will keep the chemicals in the fertilizer from getting to the plants.
You will also want to test your soil’s conductivity which can be measured in two different ways. The TDS is the total dissolved solids and it measures what amount of fertilizer you have in your soil already. Electrical conductivity measures will measure the amount of the nutrients in your soil. Knowing these levels will help you know what is in your soil and then you can decide on the amount of fertilizer you will need.
Measuring the soil temperature will let you know what to grow and how. Different crops need different temperatures to be able to germinate and it is vital that you test the soil temperature first. Make sure to measure it at the plant depth and not just at the surface. Your seed packaging will help you find out what the best temperature is for each specific plant.
