The factors affecting the fertility of soil are as follows: The property of soil depends on the property of parent rock. 9438 West SR 28West Lebanon, IN 47991PHONE: (800) SOIL - 130, © 2016 All Rights Reserved | Precision Agronomics, Inc. | 765.893.4791. is known as ‘acquired fertility’. Soil productivity encompasses soil fertility plus the inherent and management-related factors affecting plant growth and development. Meaning of Porosity of Soil: Pore-spaces (also called voids) in a soil consist of that portion of the soil volume not occupied by solids, either mineral or organic. The factors affecting soil fertility may be of two types; i.e. Different types of bacteria, fungi and algae live in the soil. Let us have a look at what is soil fertility and how can it be replenished. They include all the practices that affect fertility, the water and air relationships and the activity of the biological agents such as insects, pests, diseases and microorganisms. Therefore, it's more desirable to use soil with higher moisture content to increase and ensure its fertility. Besides this, cultivation of crops without manuring decreases the fertility of soil. These factors may include soil structure as a framework for soil life, fuel in the form of organic matter to drive the entire system, and the diversity or population of soil micro- and macro-fauna. The loss can be reduced by adding farm waste materials to the soil. Organic matter is a valuable part of soil. Organic matter contains the plant nutrients. Indian soil contains 0.3 to 0.2 per cent nitrogen, 0.03 to 0.3 per cent phosphorus and 0.4 to 0.5 per cent potassium. As it is dependent on the soil's fertility, high soil productivity would need the soil to be properly fertilized. This leads to poor crop yields. become sandy and clayey in nature respectively. Low CEC indicates the possibility of easily losing nutrients by leaching. Soil colloids are small particles and the most active portion of the soil. Save For Later Print. There are more nutrients present in soil with a higher CEC than its opposite. Microbial Mediated Micronutrient Transformation in soil Fe Zn Cu Mo Mn 2. But every productive soil has to be fertile. On the other hand, the fertility of level and becomes more, because the nutrient of high land in soluble form deposited in the level land, specially in low land. The plant do not absorb nutrient if it is not soluble in water. Soil texture and soil fertility are examples of characteristics that we may attempt to enhance. In an experiment in central farm, Coimbatore, it was found that the garden soil of nine inches depth contains 1400 lb (630 kg) potassium per acre. Factors Influencing the Fertility of the Soil Soil pH- After testing the soil, you determine the existing pH levelof the soil. The factors affecting the fertility of soil are as follows: Not only that, we dive deeper into the influential and affecting factors of the fertility of the soil. Updated: July 18, 2019.

Aeration and movement of water is good in the soil containing adequate amount of organic matter and this type of suitable condition of soil is beneficial for the growth of plant. Contact us today for more information! For the average person, it is simply treated as part of the ground and grows plants, trees, and crops. The following reaction is suggestive of what may happen to urea-. Sandy soils have CEC between 1-5meq/100g.4 Clay soils such as smectite and illite can have CECs between 25-100meq/100g.3,4 Increasing the clay … When erosion is severe, the nutrient is lost along with soil and the fertility of soil decreases accordingly. As a result, phosphate remains in the soil in unavailable form to plant. Do you think we can state that there is soil or past/present conditions and components to create soil on Mars and comet 67 P/C-G? Inherent Capacity of Soil to Supply Plant Nutrients: The nutrient contents of a soil vary according to the nature of soil. For this, the fertility of soil in temperate region becomes low. The soil which contains much quantity of nutrient becomes more fertile. Soil fertility and nutrient management is one of the important factors that have a direct impact on crop yield and quality. The factors affecting soil productivity include all those which affect the physical, chemical and biological conditions of the soil environment in which plants grow. Losses of nitrogen occur due to following reduction: The biochemical reduction of nitrate nitrogen to gaseous compounds is called ‘denitrification’ and is thought to be the most widespread type of volatilization.
