When it comes to choosing a fertilizer for your lawn and garden, there are a lot of choices and it can be confusing. We’re going to share a few things with you about how to choose the right fertilizer for the right use in your lawn and garden.
Keep in mind that most fertilizers will contain nitrogen, phosphorous, and potassium as their primary nutrients, and some will also contain micronutrients like iron, or sulfur, or magnesium. The most important part of any fertilizer label is the guaranteed analysis. This will tell you exactly how much of what nutrient is in that fertilizer. You can use this information to figure out application rates, a timing of application, and how to use the product.
A soil test will help you determine if you’re deficient in any specific nutrients or if you have something in excess. And your local Extension educator can also help you interpret your soil test and determine what fertilizer would be best for your lawn or garden. You also can buy soil test kit to know how the existing pH, Nitrogen (N), Phosphorous (P) and Potash (K) levels in your garden soil.
Luster Leaf Rapitest Soil Test Kit continues to be the standard for home soil testing. The kit includes all components needed to for (40) tests: (10) each for pH, Nitrogen, Phosphorus, and Potash. The patented color comparator system allows for easy color comparisons versus a typically printed color chart. Extensive, yet simple, instructions are included along with recommendations for over 400 plants.
Some fertilizer products come from organic sources such as blood meal or bone meal. And some come from synthetic sources. If this is an important distinction to you, be sure to read the label to determine what product you’re using. You also have a choice when it comes to liquid versus solid fertilizer sources.
A liquid fertilizer can be mixed and sprayed directly onto the leaves and can rapidly correct any micronutrient deficiencies, especially iron. A solid fertilizer can be added to the soil at planting or during the growing season, and will typically take a little bit longer to get into the plant. Be sure to have your soil test available before you go shopping for fertilizer. Test results allow you to fertilize appropriately, ensuring the best possible results.
