Knowing the basics about soil
- All garden soils are very similar, in that they are inorganic mineral combinations such as potassium, phosphorus, calcium, iron, carbon, manganese, etc., with a very small percentage of organic matter.
- Even though soils are primarily minerals such as those required for healthy plant growth, thousands of years of weathering, leaching, and crop removal have left most soils deficient in water-soluble mineral nutrients, making supplementation necessary.
- Soil provides five essential functions, which are necessary for crops to succeed:
- Provide anchorage for and protect plant roots.
- Hold water plus oxygen for plant use.
- Store minerals that plants need for food.
- Act as a temperature regulator in hot weather.
- Provide drainage of water from plant roots.
- Adding small amounts of minerals (explained in Feeding Your Plants) to your soil makes soil amendments unnecessary, and will assure fast, healthy, and uniform growth.
