If the soil in your backyard is sandy, adding organic matter can help its ability to retain water. Got dirt that is more clay-like than anything else? Then the humus formed by your organic matter helps to loosen the soil, taking it closer to the high standard of crumbly.
Another good reason to add organic matter involves the amount of carbon in your soil. Carbon is, indeed, essential for a successful garden. The presence of this promotes the growth of beneficial bacteria. This, in turn, increases the odds that your plants will be healthy, hearty and, of course, delicious.
If you're an old hand at organic farming, you've probably been doing this for many years. Your soil reflects this by being rich in nutrients already. However if you're new to organic farming or have soil lacking in certain nutrients, this may be a challenge for you. The important factor to remember when growing tomatoes is the need to rotate them with legumes once every few years. This way you can be confident that the soil is rich in nitrogen. But do not be afraid to add compost, barnyard manures and even poultry litter to the soil to help enrich it.
Scientific Evidence on the Benefits of Organic Matter
You do not have to take my word for the benefits of organic matter. The scientific community has been researching its benefits for years, even decades. They've concluded that diseases caused by a plant deficiency are usually milder in plants grown organically than in others.
These experts say that the matter not only increases the health and vigor of the plants, but it affects the behavior of the microbes as well. The organic pieces trigger the microbes to be more active.
Specifically, it can stimulate helpful and friendly microbes to attack and kill the ones who are scouting out your plants. One of the finds these studies reveal is that certain types of fungus which live in decaying organic matter actually have been found to kill harmful nematodes.
