What Is Soil Productivity And Fertility?

How do you define productivity?

Productivity is commonly defined as a ratio between the output volume and the volume of inputs.

In other words, it measures how efficiently production inputs, such as labour and capital, are being used in an economy to produce a given level of output..

Can soil lose its fertility?

Soil as such does not lose fertility just by growing crops but it lose its fertility due to accumulation of unwanted and depletion of wanted inorganic salts from the soil by improper irrigation and acid rain water (quantity and quality of water).

What is soil fertility and why is it important?

Soil fertility is the ability of a soil to sustain plant growth by providing essential plant nutrients and favorable chemical, physical, and biological characteristics as a habitat for plant growth. Plant nutrients include the macronutrients nitrogen, phosphorus and potassium, sulfur, calcium and magnesium.

How can I make my soil less fertile?

Effectiveness of four techniques aimed at reducing soil fertility i.e. straw/stubble burning, topsoil stripping, specific fertiliser additions to increase crop yield and hence increase removal of other nutrients with the crop, and livestock grazing, were reviewed.

What is soil productivity?

Soil productivity is defined as the capacity of soil, in its normal environment, to support plant growth. Soil productivity is reflected in the growth of forest vegetation or the volume of organic matter produced on a site.

What are the factors affecting soil fertility?

The following factors affect the soil fertility:Mineral Composition. The mineral composition of the soil helps to predict the ability of the soil to retain plant nutrients. … Soil pH. … Soil Texture. … Organic Matter. … Adding Manures and Fertilizers. … Leguminous Crops.

What is the importance of soil fertility and soil productivity?

Soils feed the plants which in turn feed the animals that feed us. Including soil in this important chain will help guarantee its success. Soil provides the support or foundation for plants and most of the nutrients. Soil is accumulated decomposing plant and animal matter with aging parent material.

How many types of soil fertility are there?

The factors affecting soil fertility may be of two types; i.e. – (a) Natural factor and (b) Artificial factor. The natural factors are those which influence the soil formation and the artificial factors is related to the proper use of land. The factors affecting the fertility of soil are as follows: i.

What affects soil productivity?

Soil productivity encompasses soil fertility plus the inherent and management-related factors affecting plant growth and development. … Agricultural management decisions regarding tillage, fertilization, crop rotation, irrigation, and drainage are among the practices that can significantly affect soil productivity.

What is the advantage of fertile soil?

Crops need nutrients just like people do. A fertile soil will contain all the major nutrients for basic plant nutrition (e.g., nitrogen, phosphorus, and potassium), as well as other nutrients needed in smaller quantities (e.g., calcium, magnesium, sulfur, iron, zinc, copper, boron, molybdenum, nickel).

Which is the most fertile soil?

Alluvial soilAlluvial soil is the most fertile soil because it has loamy texture and is rich in humus. It has good water absorbing capacity and water retention capacity.

What is soil fertility What are the sources of soil fertility?

Sources of soil fertility are manure, fertilizers, plants absorb water and minerals from the soil, which is essential for growth, flowering, crop yield, and other vital activities. The soil is a storehouse for organic and inorganic plant nutrients.

How can we preserve soil quality and quantity?

Soil Quality Management: Key Strategies for Agricultural LandEnhance organic matter. … Avoid excessive tillage. … Manage pests and nutrients efficiently. … Prevent soil compaction. … Keep the ground covered. … Diversify cropping systems.

What is meant by soil fertility?

Soil fertility is the ability of soil to sustain plant growth and optimize crop yield. This can be enhanced through organic and inorganic fertilizers to the soil. Nuclear techniques provide data that enhances soil fertility and crop production while minimizing the environmental impact.

Why productive soil is always fertile?

A fertile soil contains an adequate supply of all the nutrients required for plant growth. The full potential of crops is not realized if a shortage of nutrients occurs at any time during the growth cycle. This is true even though plants are capable of remarkable recovery from short periods of starvation.

How do you maintain soil productivity?

Management Practices to Improve Soil HealthReduce Inversion Tillage and Soil Traffic. Excessive tillage is harmful to soil health in a number of ways. … Increase Organic Matter Inputs. … Use Cover Crops. … Reduce Pesticide Use and Provide Habitat for Beneficial Organisms. … Rotate Crops. … Manage Nutrients.Jul 31, 2017

How can I make my soil fertile?

Make sure your nutrient balance is right Most plants thrive only when the soil has the right balance of acidity and alkalinity. If the soil is too acidic, or below 5.5 on a soil pH scale, you’ll need to add ground limestone. If it’s too alkaline, more than 7.5 on the pH scale, you should add soil sulfur.

How do you manage soil quality?

Managing soils to improve biologyManage soil pH. Beneficial soil biology requires soil pHs to be near neutral. If soils are strongly acidic, apply lime to correct pH. … Use organic fertilisers. Consider substituting some of your inorganic fertilisers with organic fertilisers such as composts and manures.
