When your garden comes to a screeching halt with little warning, do you ever blame it on "that darn clay soil" or that "baking hot, no good sandy soil" of yours? If you do, then you have more than an inkling as to how soil texture can affect your organic garden. In order to learn how to work with your soil's natural texture (which can't easily be changed), you'll first need to find out what your soil's texture is.
Soil Texture- Is it sand, silt or clay?
You should know whether you have a light or heavy soil. Commonly, soils with lots of sand are referred to as light soils and soils with lots of clay are known as heavy soils. Both have advantages and disadvantages. Sandy soils warm up earlier in the spring, have better drainage and seem to suit certain crops (carrots, for example) better than clay soils. Clay soils, on the other hand, usually have better water- and nutrient-holding capacity. This means that you may be able to get away with less frequent watering than you could with a sandy soil, and that your nutrients will stay put better than they would in a sandy soil.
You can figure out your soil's texture (sandy, silty, or clay) with no tools except your bare hands and a little bit of water. If your soil feels very gritty and won't stick together when wetted, it's sand. If you can make it into a long ribbon or snake just like you did in art class in kindergarten, then it's clay. Your soil is probably not either of these but a mix of sand, silt and clay (big, medium and small particles).
Some soils have textures that are known as sandy clay loam or silty clay loam. This just means that they have a fair amount of sand, silt and clay in them.
Once you know what your soil's texture is, you will be able to make more informed decisions about what crops to grow and when to plant them, how often to water your garden and how much compost (or other sources of nutrients and organic matter) you need to add to help your crops stay healthy.
It is important to realize that any soil, no matter what texture, can benefit from having organic matter, such as compost, added to it. Organic matter helps clay soils become better aerated and lighter, so they will be less likely to turn brick-hard just when you were planning on putting your tomatoes in. Organic matter helps sandy soils absorb more water so that your garden crops will be thirsty less often. It also provides an organic source of nutrients to your plants.
By identifying your soil's texture and becoming informed about the advantages and disadvantages of its texture type, you'll gain a new appreciation for your soil and it's natural characteristics. This is the first step in reaching a truce with troubled garden soils and learning to appreciate your soil.
Soil pH is a measure of how acidic or alkaline your soil is. The number you get when you test your soil's pH can tell you whether your plants are likely to thrive in your garden spot or not. Luckily, if the answer is no, there are ways to change your soil's pH and make your garden into a more hospitable environment for your vegetables, flowers and lawn.
In order to grow successfully, your plants need good soil. This includes the right drainage, pH balance, and conditions. Without good soil, valuable time and investment will probably be lost. Since most soils need some amount of improvement, here are some things you can do to help them along.
