What is an organic garden?
The organic garden can be defined as a garden in which gardeners don't use synthetic fertilizers as nutrients to feed their plants, chemicals to control weeds and pesticides to manage insect pests. This means organic gardening is a chemical free gardening practice, which prevents harming environment, and human and domestic/wildlife health. This practice also doesn't harm the beneficial insects such as honey bees that play an important role in pollination of many plant species grown in the organic gardens. Also, in the chemical free organic garden, the populations of natural enemies including predators and parasites thrive well and helps to suppress the populations of insect pests.
What are the sources of plant nutrients in the organic gardening?
Soil is the basic source of plant nutrients such as nitrogen, phosphorus and potassium but this source can be easily depleted because of continuous cropping in the garden.
