Let’s talk about what has swayed me toward organic.
Organic fertilizers have two basic advantages. First, organic fertilizers always contain many micronutrients such as iron, copper, zinc and manganese. Although chemical fertilizers sometimes have added micronutrients, most only contain nitrogen, phosphorus and potassium. Although plants use very small quantities of micronutrients, they can become limiting to plant growth if not available in the soil.
Second, organic fertilizers are released gradually into the soil so they are gradually available for plant growth. The nitrogen in chemical fertilizers is usually very soluble and released quickly into the soil. Much of it is often leached past the root zone of the plants and has to be applied more frequently.
A good example is liquid fertilizer applied by lawn service companies. They typically make five or six applications, whereas two applications of granular organic fertilizer is sufficient.
Chemical pesticides applied to control damaging insects also can harm bees and other pollinating insects if applied at the wrong time. Herbicides applied to kill weeds can damage desirable plants.
All chemical pesticides can be damaging to the applicator if inhaled or spilled on the skin, especially when in concentrate form. Always wear long pants, long shirts and gloves when handling pesticides. Now that we are all familiar with face masks, wear one of those also. Pesticide residues can be harmful to children and pets for several hours after application.
Pesticides, especially when over applied or applied too often, dissolve and find their way to creeks and ponds where they can damage fish and other wildlife.
Organic insecticides and fungicides are now available to control most insects and plant diseases. As for herbicides, I now remove almost all my weeds by pulling, digging or cultivating. I have found that if I spend five to 10 minutes a day weeding (usually in the early morning) I have completed all my weeding for the week. Of course frequent mulching has reduced my weed population by about 90 percent.
