Q. Why is loosening of soil important for growth of plant?
Loosening the soil allows the roots of crops to penetrate deep into the soil and allows the roots to breathe easily.
Q. How loosening of soil helps the plants?
The first step before growing a crop plant is the preparation of soil for sowing of seeds, the soil has to be loosened so that the roots of plants may penetrate deep into the soil, the loosening of soil allow the roots to breathe easily because loosened soil promotes growth of organisms like earthworms and microbes …
Q. Why loosening of soil is important for plants give atleast 4 points?
[1] The roots can breathe easily in loose soil. [2] It allows the roots to penetrate deep into the soil. [3] It increases water holding capacity of soil.
Q. How does soil structure affect plant growth?
Soil structure affects plant growth by influencing root distribution and the ability to take up water and nutrients. Disturbance of soil structure through compaction or tillage can result in the rapid recycling of nutrients, crusting (the hardening of the soil surface layer) reduced water and air availability to roots.
Q. Why is soil structure important?
A good soil structure is important to allow air and water into the soil which are vital for healthy plant growth. It will improve drainage and reduce soil erosion caused by excess surface run-off. Without structure, soils will suffer from anaerobism, waterlogging and nutrient lock-up and, ultimately, plants will die!
Q. How can you change the texture of soil?
While changing a soil’s basic texture is very difficult, you can improve its structure–making clay more porous, sand more water retentive–by adding amendments. The best amendment for soil of any texture is organic matter, the decaying remains of plants and animals.
Q. Which property of soil Cannot be changed easily?
soil texture
Q. How is soil structure maintained?
You can improve the structure of sandy soils by regularly adding organic matter in the form of compost or composted manure. Adding basalt to these soils is one way of improving their ability to retain water and minerals.
Q. What are the factors that affect soil pH?
Inherent factors that affect soil pH include climate, mineral content, and soil texture. Natural soil pH reflects the combined effects of the soil-forming factors (parent material, time, relief or topography, climate, and organisms). The pH of newly formed soils is determined by the minerals in the parent material.
Q. What increases soil pH?
Increasing the Soil pH. To make soils less acidic, the common practice is to apply a material that contains some form of lime. Ground agricultural limestone is most frequently used. The finer the limestone particles, the more rapidly it becomes effective.
Q. How do you maintain pH in soil?
Elemental sulfur may be used to acidify alkaline soil to the desirable pH range. It may also be used to maintain pH in the desirable range, on soils that tend to become alkaline with management. When elemental sulfur is applied to soil, it combines with oxygen and water to form sulfuric acid.
