Which soil and plant condition indicates a need for irrigation

rooting depth

Explanation:

The need for water of plants is determined by the degree of soil moisture. The optimal soil moisture for most vegetable plant species is between 70 - 90%.

When the soil moisture is below 60%, most plants show a symptom of lack of water in the form of sports development of plants, flowers, and fruits fall off, while excessive watering can lead to rot of the plant or the plants have a lush increase, they become thin…

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
