Good soil builds great gardens. Yet few gardeners are blessed with perfect soil. Conventional gardening practices call for the addition of multiple chemical-based fertilizers to enhance the soil, but organic gardeners who eschew such practices need alternatives. The answer lies in replenishing your soil with organic materials to grow healthier, tastier vegetables.

All gardeners spend a great deal of time and energy on replenishing their soil, but when you switch to organic gardening practices, the care and feeding of your soil is more important than ever.
What Is Soil?
Soil consists of many layers of pulverized rock, decomposing leaves and other organic materials. But surprisingly enough, it also contains air and water. Soil is comprised of 45 percent minerals, 30 percent air, 20 to 30 percent water and 5 percent organic materials.
It’s that last 5 percent that most gardeners concern themselves with when they speak of recharging the soil. Additives including manures, cover crops and compost replenish the nutrients in the soil and improve the soil structure. Like the alchemist’s quest to turn base metals into gold, “brown gold” additives such as compost and well-aged manures transform sticky clay soils one step closer to the much-desired sandy loam.
Start With a Soil Test
Before planting a single vegetable in your garden, test your soil.
Soil tests analyze:
Macro nutrients such as nitrogen, phosphorous and potash contribute to healthy leaves, plentiful flowers and healthy roots respectively. Micro nutrients including calcium, iron, copper, magnesium and other minerals enhance plant health. Each plant requires different amounts of nutrients for optimal health and vitality.
Once you have your soil test results, you’ll know what to add to the soil to create the optimal conditions for growing vegetables.
The Care and Feeding of Garden Soil: Organic Amendments
With your soil test results in hand, you’re ready to add amendments to your garden soil to adjust the pH, improve fertility and grow great vegetables.
Organic Gardening Practices That Recharge the Soil
As part of your organic gardening practices, it’s helpful to include several gardening practices into your vegetable garden. These practices include:
How to Get Your Soil Ready for Spring
Now is a great time to get your soil tested and ready for spring planting. If your garden soil is still hard from the harsh winter, cover the area with a large black tarp pinned down by several stones on each side. In 3 to 7 days the ground should be warm enough to start planting.
There’s an art and a science to soil, but it’s not something you need to understand all at once. Build up your knowledge slowly over time, just as you build up your soil.
