rainwater
Fertile soil, moisture, air and light
Moisture, nitrates, phosphorous, potassium, calcium, etc. that are incorporated into the soil that encourages plant growth.
The best soil in which we can plant rice is loam soil or alluvial soil. They both are useful as they can retail water and moisture.
The following factors affect plant growth: Soil temperature Incident light Soil moisture Humidity

No. But shredded it will act as a mulch and conserve moisture that will benifit plant growth.
Robert Peter Scammell has written: 'Soil moisture-plant growth relations and irrigation requirements'
which is the best soil for plant growth.
The bulbs will be dry when you plant them but will pick up moisture from the soil that will trigger growth.
One non living factor that affects cactus growth is slow draining soil. A cactus plant prefers free draining soil that holds some moisture. It doesn't tolerate waterlogging. Another non living factor is the level of heat, light, and moisture. A cactus plant likes high heat in the desert and jungle, high light and low moisture in the desert, and low light and high moisture in the jungle.
soil and plant
Temperature, Precipitation, Type of Soil. And several more. Soil nutrients, moisture, temperature, intensity and duration of light, insects & pathogen and growth hormones etc.
