Detailed explanation-1: -The principal environmental requirements for plant growth include adequate space for root and canopy development, sufficient light, water, oxygen, carbon dioxide, and mineral elements, and temperature suitable for essential physiologic processes.
Detailed explanation-2: -The four things that plants receive from soil are? Anchorage of roots, oxygen, moisture, nutrients. Certain plant food elements are called major elements because?
Detailed explanation-3: -Plants grow best when daytime temperature is about 10 to 15 degrees higher than nighttime temperature. Under these conditions, plants photosynthesize (build up) and respire (break down) during optimum daytime temperatures and then curtail respiration at night.
Detailed explanation-4: -Capillary water is the most important for crop production because it is held by soil particles against the force of gravity. As water infiltrates into a soil, the pore spaces fill with water.
