What is the contribution of soil water to plant growth?

cellulose is made up of carbon, oxygen, and hydrogen. Hydrogen and part of oxygen come from water. In addition, plants live in a watery environment like other living organisms and lose a certain amount of water through evaporation, and this must be composed of groundwater that enters through the roots.

What is the contribution of soil water to plant growth?

Water is the most fundamental ingredient necessary for life. There is no aspect of growth, whether considered at the level of gene expression, metabolism, cell division or cell expansion that can occur in the absence of water.

The capacity of the soil to retain water is strongly related to the size of the particles; Water molecules adhere more strongly to fine particles in clay soil than to coarser particles in sandy soil, so clays generally hold more water. On the contrary, the sands facilitate the passage or the transmission of the water through the profile.

Soil water (retention)

From Wikipedia, the free encyclopedia

Soils can process and retain a considerable amount of water. They can absorb water and will continue to do so until they are full or the rate at which they can transmit water to and through the pores is exceeded. Some of this water will constantly drain through the ground (via gravity) and end up in streams and streams, but much of it will be retained, despite the influence of gravity. Much of this retained water can be used by plants and other organisms, thus contributing to the productivity of the land and the health of the soil.

Soil water retention edit

The pores (the spaces that exist between the soil particles) allow the passage and / or retention of gases and humidity within the soil profile. The capacity of the soil to retain water is strongly related to the size of the particles; Water molecules adhere more strongly to fine particles in clay soil than to coarser particles in sandy soil, so clays generally hold more water.

On the contrary, the sands facilitate the passage or the transmission of the water through the profile. The type of clay, the organic content and the structure of the soil also influence the water retention of the soil.

The maximum amount of water that a given soil can hold is called the field capacity, whereas soil so dry that plants cannot release the remaining moisture from soil particles is said to be at the point of wilting.

Available water is that which plants can use from the soil within the range between field capacity and wilting point. Generally speaking for agriculture (top layer soil), the soil is 25% water, 25% air, 45% mineral, 5% other; water varies widely from about 1% to 90% due to various retention and drainage properties of a given soil.

The role of soil water retention is profound; its effects are far-reaching and the relationships are invariably complex. This section focuses on a few key roles and recognizes that it is beyond the scope of this discussion to encompass all the roles that can be found in the literature.

The process by which the soil absorbs water and the water drains down is called percolation.

Soil water retention and organism edit

Soil water retention is essential for life. Provides a continuous supply of water to plants between replenishment (infiltration) periods, to allow for continued growth and survival. For example, in much of the temperate zones of Victoria, Australia, this effect is seasonal and even year-on-year; Retained soil water that has accumulated in previous wet winters allows most perennials to survive during typically dry summers, when monthly evaporation exceeds rainfall. Soils generally contain more nutrients, moisture, and humus.

Soil water retention and climate edit

Soil moisture has an effect on the thermal properties of a soil profile, including conductance and heat capacity.

The association of soil moisture and soil thermal properties has a significant effect on temperature-related biological triggers, including seed germination, flowering, and wildlife activity.

(more water causes the soil to gain or lose temperature more slowly with the same heating; water has approximately twice the heat capacity of the soil)

Recent climate modeling from Timbal et al. (2002)

suggests a strong link between soil moisture and the persistence and variability of surface temperature and precipitation; further, that soil moisture is an important consideration for the accuracy of "interannular" predictions for Australian climate.

Soil water retention, water balance and other influences edit

The role of soil in water retention is significant in terms of the hydrological cycle; including the relative ability of the soil to retain moisture and changes in soil moisture over time:

  • Soil water that is not retained or used by plants can continue down through the profile and contribute to the water table (the permanently saturated zone at the base of the profile); This is called "reloading." Soil that is in field capacity (among other reasons) can impede infiltration to increase surface flow. Citation needed Both effects are associated with groundwater and surface water supply, erosion, and salinity.
  • Soil water can affect the structural integrity or coherence of a soil; Saturated soils can become unstable and result in structural failure and mass movement. Soil water, its changes over time, and its management are of interest to geotechnicians and soil conservationists interested in maintaining soil stability.

In nature, the nitrogen cycle runs through microorganisms in the same way that carbon runs through plants. Just as plants are able to "fix" atmospheric carbon to sugar molecules, nitrogen-fixing bacteria can fix atmospheric nitrogen to organic molecules that include nitrogen, carbon, and hydrogen.

Some of these molecules are associated with the roots of plants. Plants of the legume family (peas, beans, and other pod-forming plants) exchange photosites for fixed nitrogen in a mutualistic symbiosis. These plants concentrate nitrogen and can contribute it to the soil when part or all of the plant dies.

Of course, humans who practice agriculture contribute huge amounts of nitrogen fertilizer to farmland every year. They can be chemical salts like urea or ammonium sulfate, or organic waste with relatively concentrated amounts of nitrogen. Of organic sources, chicken manure is among the highest in nitrogen, but still much lower than chemical sources.

There is little chemistry and physics behind this. Perspiration, which is the main cause of water loss from plants, is said to create a water deficiency in the upper parts, whereby the water goes from a high concentration to a low concentration. But this was not possible if the diameter of the vessels was very large. So the glasses have a very narrow diameter ... so the water, adhering to their wall and cohesively to themselves, finally moved.

It is a race from more to less water. It is similar to that situation when you draw water from your mouth through a pipe where one end of the pipe remains submerged in water ...

Plants can be grown in ANY horticulturally stable growing medium other than soil, with the right nutrients, light and temperature, as long as the density of the growing medium is appropriate for the plants in question.
In some cases, they can be grown without any growing medium.
Like the nutrient film technique and many others.

Hydroponics has practically been around forever!

StoneBroke Manor Hydroponics History Reader Please Note: This is a very lengthy document, a single chapter from one of the author's books. However, it has been subdivided into five sections consisting of The Past, The Present, Why Grow Food, Food Trends in America, and The Future. These links should help you relocate the individual sections, for your reading pleasure. HISTORY OF HYDROPONICS Hydroponics, the cultivation of plants without soil, has developed from the findings of experiments carried out to determine what substances make plants grow and the composition of plants. This work on the components of plants dates back to the 17th century. However, the plants were being grown in soilless culture long before this. Hydroponics is at least as old as the pyramids. A primitive form has been carried out in Kashmir for centuries. The hydroponic growing process in our oceans dates back roughly to the time the earth was created. Hydroponic cultivation preceded cultivation in soil. But as an agricultural tool, many believe it started in the ancient city of Babylon with its famous hanging gardens, listed as one of the Seven Wonders of the Ancient World, and was probably one of the first successful attempts to grow plants hydroponically. The floating gardens of the Aztecs of Central America, a nomadic tribe, were led to the marshy shore of Lake Tenochtitlán, located in the great central valley of what is now Mexico. The Aztecs, treated roughly by their more powerful neighbors, without arable land, they survived exercising remarkable powers of invention. As they did not have land to cultivate, they decided to make it with the available materials. In what must have been a long process of trial and error, they learned how to build rafts out of reeds and rushes, tying the stems together with tough roots. They then dredged dirt from the shallow bottom of the lake and piled it onto the rafts. Because the soil came from the bottom of the lake, it was rich in a variety of organic debris, decomposing material that released large amounts of nutrients. These rafts, called chinampas, had abundant crops of vegetables, flowers, and even trees planted on them. The roots of these plants, pushing towards a source of water, would grow through the floor of the raft and go down into the water. These rafts, which never sank, sometimes joined together to form floating islands up to sixty meters long. Some chinampas even had a cabin for a resident gardener. On market days, the gardener could place his raft near a market, picking and delivering vegetables or flowers as buyers bought them. By force of arms, the Aztecs defeated and conquered the peoples who had previously oppressed them. Despite its large size, their empire eventually took over, they never left the site on the lake. His once rough village became a huge and magnificent city and the rafts, invented in a bid to avoid poverty, proliferated to keep up with the demands of the capital city of central Mexico.

Plants help create and preserve soil.

In the forest and meadow, the roots of the plants help to hold the earth together. This reduces erosion and helps conserve the soil. Plants also help produce soil. Soil is made up of many rock particles that break down into very small pieces. When plants die, their decomposed remains are added to the soil. This helps make the soil rich in nutrients.

As anyone who has used the raft system to grow plants hydroponically can tell you, the kinds of roots that plants lay in water are different than the roots they lay in soil. Plants grown in water will have fine white / cream fibrous roots. Plants that grow in the ground will have rough brown woody roots. Fun Fact: The little houseplants found in the flower section of big markets were likely grown hydroponically and placed in the ground long enough for new roots to grow before being sold.

Soil pH is important because it influences several soil factors that affect plant growth, such as (1) soil bacteria, (2) nutrient leaching, (3) nutrient availability, (4) toxic elements, and ( 5) soil structure. ... Plant nutrients are generally most available to plants in the 5.5 to 6.5 pH range.

Water is used for transpiration and carries nutrients from the soil to green plant tissues. ... Water is essential for the germination of seeds, the growth of plant roots and the nutrition and multiplication of soil organisms. Water is essential in the hydraulic process of the plant. Helps in the conversion of starch to sugar.
