For a plant to grow, it needs five elements: sunlight, air, moisture, nutrients and proper temperature. Four of these five elements depend on the quality of the soil you use. Without the right soil, your plant will not get the air, moisture or nutrients it needs to survive.
Is all soil the same, or does organic soil make a difference in your garden? Keep reading to find out.
One of the first things you probably learned when venturing into the rewarding world of gardening was that dirt is not soil. The difference between the two is that dirt is not alive, but soil is. If all you have is dirt, your plants will never grow. In other words, all soil is organic.
Organic is a popular marketing buzzword that has become synonymous with "healthy" in the food world. This is because food that is labeled USDA-Certified Organic is the most heavily regulated food system in the U.S. However, when the word organic is used in conjunction with soil, it is not a certification; it’s more of an adjective that might not mean what you think it means.
While it can seem confusing that all soil is organic, but not all soil is labeled organic, there is a difference. Regular soil is manufactured using ingredients such as peat moss, bark, perlite, vermiculite and styrofoam. While some of these ingredients are organic, they don’t usually contain impressive amounts of nitrogen, phosphorus or potassium, the three elements needed for plant growth. The rest of the ingredients found in regular soil help with water drainage and aeration, so plants’ roots can get sufficient moisture and oxygen.
On the other hand, organic soil contains ingredients such as compost, seaweed, fish meal, bat droppings, bone meal, soybean meal, manure and worm castings. These items add essential nutrients to the soil, raising the level of nitrogen, phosphorus or potassium so a plant can thrive. In short, using organic soil is roughly the equivalent of a human having a purposeful, nutrient-rich diet – all the elements needed for healthy growth are present.
Like everything else in life, organic soil has its pros and cons.
