The main aim of using a dry fertilizer is to provide all the needed nutrients to a tree or plant for it to grow healthy and strong. In our gardens, and in particular landscape gardens, the soil must be especially rich in nutrients such as potassium, phosphorus and nitrogen to cater to all the plants' and trees' needs. By applying a fertilizer the level of these nutrients will increase, offering a richer and healthier environment. Here is some information about dry fertilizer and how you should use them correctly.
Advantages of a Dry Fertilizer
The greatest advantage of a dry fertilizer is that it dissolves slowly into the soil. For this reason it is generally used in large fields since it lasts longer than any other fertilizer. In addition, there is a much smaller risk of damaging crops and plants when using a dry fertilizer rather than a liquid one, which on the other hand can slowly burn the plants.
Chemical Dry Fertilizer
This synthetic fertilizer is produced in factories and basically is made of different mixtures of chemicals which together make up the best formula for a particular soil. Although it is not natural, this fertilizer is very effective and once applied, the results will be seen in a short period of time. Chemical dry fertilizers are inexpensive and they can be easily applied using a spreader.
Organic Dry Fertilizer
The other type of granular fertilizer is the organic one. This fertilizer is totally made of natural materials such as compost and manure which are left to dry and then used in gardens or fields. Even if this fertilizer is often tested before retail, it does not always contain an accurate balance of nutrients such as a chemical one. However, an organic fertilizer increases the activity in the soil since microbes will have more organic matter to turn into rich nutrients for the plants.
The best time to use a dry fertilizer is during the soil preparation prior to planting. Once dry, the fertilizer, either chemical or organic, should be mixed with the soil so that the much needed supply of nutrients can be readily available to all of the plants to be planted there. When mixed, you can immediately notice the difference in the soil's texture which will look much more compact and so perfect for planting.
Apart from being used in soil preparation, granular fertilizers can also be applied directly to existing plants or trees. However, it needs to be watered in order to settle and dissolve in the soil otherwise, it will not reach the roots and it will eventually burn the plant. A great way to apply dry fertilizer to existing trees is by spreading it one foot away from the tree's bark, all around the tree. This way the fertilizer can reach the roots without coming in direct contact with the tree or plant itself.
Finally, the greatest advantage of a dry fertilizer is that it is very durable. Nevertheless, avoid spreading dry fertilizers during the rainy season since the rainfall can carry away a lot of the fertilizer's nutrients. Furthermore, it is always better to test your soil before adding any kind of fertilizer to it.
