Here are my top personal reasons for composting. I only hope that you move your butt out of that chair and begin your own compost pile before you reach number ten.
The first reason I find composting highly worthwhile is the fact that the materials used are absolutely free and are readily available. Compare that with the ever rising costs of commercial fertilizers and other gardening products in the market today. All you need is a little extra effort to find the best materials for your compost pile, but otherwise, everythings for free.
The second one is that compost provides more nutrients and minerals needed by my plants than commercial organic or synthetic fertilizers. The overall effect of compost is also longer than commercially available fertilizers. Its free and it works better, who wouldnt want that? Plus, if you organize your ingredients just right, you can provide a whole lot more range of nutrients.
Another good reason would be the benefits of compost to the soil structure. When applied to the soil, compost can help the soil be more resistant to erosion, improve its retention of water, and in some types of soil (like clay) it can reduce the chance the soil becomes compact. This is also important for farmers since compost can make the soil easier to till conserving time and fuel needed to operate the machines.
With the right composting technique, the process can kill those troublesome weeds as well as pests and disease-causing organisms present in the materials being composted. High temperature composting is the technique I am talking about. Although, this technique is not the backyard variety but rather a more laboratory or industrial type variety, I still find it a good reason why we should make composts.
There have been studies which indicate that using compost can suppress the growth of diseases in crops. Other studies also show that crops grown over compost rich soils can resist better pest or insect attacks. Likewise, some news and observations in the field also shows that crops grown using compost bear produce that can be stored longer. If thats not reason enough, I dont know what else you are looking for.
For the environmentalists and conservationists, compost has something for them as well. Using compost together with the soil can build soil carbon which can eventually reduce the carbon dioxide in the atmosphere. It may take a lot of compost to have a positive effect on the greenhouse gases but that fact is quite useful as well.
It is also found out that compost works well as an antidote for soils that are toxic with agricultural chemicals. Compost can balance the levels of soil acidity, and helps farmers to go organic after years of using synthetic agricultural products.
These are my top reason for composting. Some of it may not directly benefit my personal needs but having those reasons to cling onto is a good thing to motivate the use of compost.
