What are the perfect conditions for diseases to occur?
Dead Soil Chemical over use destroys all soil bacteria expect for a few specific types of bad bacteria that depend on these conditions to grow. Urea when used over many years, destroys this balance of good and bad bacteria. Stressed Plants Dead soil increases the plant’s stress levels due to bad conditions for plant growth. High Nitrogen High nitrogen causes rapid growth. Rapid growth without proper nutrition causes more stress which in turn restricts more nutrition from being absorbed by plants. High nitrogen also attracts insects that have mutated to handle plants that have such rapid growth. High nitrogen also mutates bacteria into rapid growth cycles. Environmental stress can be from improper watering to weather cycles such as too much rain or drought. Biological considerations. Planting the wrong variety or type of plant in the wrong environment will certainly cause major stress to plants and all involved. Over Chemical use of any type from pesticides to herbicides, etc. will caus
