When you are a small-time gardener, there is no point in using conventional methods in growing. By conventional, I mean using chemicals and unnatural fertilizers as a way to promote the growth of your plants. The reason that these are used at all is because when industrial farmers need to have massive outputs, it becomes extremely inefficient to go the organic route. You would need a lot more manpower to administer natural fertilizers and other things of the like, and that would drive prices a lot higher. There is a reason that organic food is more expensive than inorganic food, and it has to do with the amount of labor that goes into making crops in a completely organic manner.
Since none of us have to worry about mass production, we can use organic techniques without any problems. However, it is important that you plan for the use of organic gardening in your vegetable garden design. When you are carrying out organic gardening, you need to understand that it is an entire practice, and in order for it to work most effectively, you need to know all the ins and outs. By doing this, you can be successful without using any chemicals at all.
Keep in mind that because you are not using inorganic techniques, you will ultimately have less power to work with, although you will be protecting your garden in the long-run and the quality of your crops in the short-run. Therefore, you have to design your garden in a manner that it can get as much sunlight as possible, as well as a steady supply of water and natural nutrients. These need to be perfect if you want to get large yields using organic methods, but it is definitely possible as long as you know all the principles behind designing an organic garden.
