Sometimes I volunteer at an urban farm]=
What are some things you do when volunteering that is the practice of cultivation right? 
Urban farming is growing crop in the the urban areas. I help weed the areas, water them, and transplant the plants when needed. Mostly onions.
Do you do organic farming as well I prefer organic so much healthier? 
yes! I have found that natural herbs and other plants can help keep the bugs away. I don't use any chemicals. To keep the weeds down, we use bales of straw and newspaper. 
That is great a lot of countries and people are practicing organic foods and it is increased interest a lot. 
That's good. The less chemicals the better. I'm glad it is increasing and peaking interest around the world. Organic is the way to go. 
Do the farm you volunteer at sell food to whole markets I do alot of  shopping there for more fresh flavors, colors and sweeteners in my fruits and vegetables.
