Soil Composition and Choosing Fertilizers

Does anyone know what this picture is?? I know it doesn't look like much, but it's my freshly tilled garden waiting for wonderful vegetables to grow. My sweet husband (who is not a gardener), took the rototiller out Monday to work the soil and enlarge the garden a little for me. He also installed a sweet irrigation system that will make it much easier to keep everything watered. If you look carefully, you will see markers where the kids planted our first row of Swiss chard, kale, and beets. I love this time of year, getting everything ready and dreaming of what will grow and having fresh vegetables after a long winter.

I thought I would talk a little about fertilizing and soil composition. I know that many are gardening for the first time this year. There seems to be a lot of excitement around growing your own food which is wonderful. I find gardening very relaxing and enjoyable. Where it becomes difficult though is when one goes to the hardware store/nursery to decide which fertilizer/food to feed one's garden.

There is this underlying competition in gardening that makes us want to have the biggest/reddest tomatoes, the most beans on one bush, and the giant pumpkin of the patch. Before "going organic" I will admit that I chose fertilizers based on those criteria. Now I realize that even more than feeding the plants in my garden, how I build up the soil of my garden directly affects my own nutrition. For instance, if beans are rich in calcium - which my body needs, but my soil is deficient in calcium I won't get the benefit of eating the beans that I grow. I must supplement my soil with the things that my plants need and that I myself need.

Plants, unlike humans are able to use both organic and inorganic sources of minerals. They can draw inorganic/rock minerals into their structure and convert it into organic/living matter that we as humans can digest and use. Inorganic minerals (table salts) do us very little good and can actually build up in our bodies and cause harm. We were created to live in this beautiful symbiosis with plants. They give us organic minerals and oxygen to breathe and we give back carbon dioxide and fertilize them with what they need.

The best garden soil contains a mixture of organic (living) matter like compost or manure and inorganic matter like organic mineral fertilizers. You might ask why synthetic fertilizers are bad?? Don't they contain the same minerals that the plants need? Synthetic fertilizers are chemically derived instead of found in nature. Some of these chemicals have been linked to cancers and other health problems. In addition, organic produce is substantially higher in nutrients, which leads to the conclusion that plants don't absorb and assimilate these synthetic chemicals appropriately. Lastly, synthetic fertilizers usually give a plant a quick boost and then are washed from the soil. Organic fertilizers are basically rock which through the aid of microorganisms in the soil slowly release nutrients to plant throughout the growing season.

Below is a great chart of some of the most important minerals that our bodies and plants need, what they do, how to supplement your garden organically with them, and which veggies/fruits are especially high in them.

Happy Gardening! I would love to hear about and see pictures of your gardens!

Wow! I wish I had a garden! That was so informative... I'm definitely bookmarking this for when I do get a garden.

I can honestly say that I have never thought of the soil nutrients this way in relation to the veggies I grow. I will be adding more to my garden area this year! Thanks for the great heads up.
