To the organic food enthusiast, organic gardening implies production of vegetables in soils with high levels of organic matter supplied from animal manure, crop residue, and compost, and without supplementary mineral elements, except those from natural mineral fertilizers obtained from natural deposits. Any attempt to control disease, insects, or nematodes is made by planting resistant varieties, using other biological means or cultural practices, or using naturally occurring pesticides obtained from plants. Weeds are controlled by cultural practices, such as hoeing, instead of by synthetic fertilizers, pesticides, or herbicides.
