Eco-environment and crop growth
The ecological environment is the basic condition for crop growth, including light, temperature, moisture, soil
It's natural. According to agroecology

Growing crops
Fertility is closely linked to the ecological environment, where appropriate environmental conditions can significantly improve yields and quality. Light
The photocooperative efficiency of crops is directly affected by the intensity of the light and the light cycle. For example, wheat is in the sun
It's higher than a vaginal crop. Approximately
