What are the three main plant nutrients in fertile soil? 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
Boron
Boron is a chemical element with the symbol B and atomic number 5. Produced entirely by cosmic ray spallation and supernovae and not by stellar nucleosynthesis, it is a low-abundance element in the Solar system and in the Earth's crust. Boron is concentrated on Earth by the water-solubility of it…
Molybdenum
Molybdenum is a chemical element with the symbol Mo and atomic number 42. The name is from Neo-Latin molybdaenum, from Ancient Greek Μόλυβδος molybdos, meaning lead, since its ores were confused with lead ores. Molybdenum minerals have been known throughout history, bu…

What are the factors that influence soil fertility?
Soil fertility is influenced by the physical, chemical and biological properties of soil. These are the two factors that determine soil fertility Adequate nitrogen and phosphorus content in the soil makes the soil more fertile. Organic materials also play an important role in increasing soil fertility.
What are the 3 major nutrients that are used to fertilize crops?
Most fertilizers that are commonly used in agriculture contain the three basic plant nutrients: nitrogen, phosphorus, and potassium. Some fertilizers also contain certain "micronutrients," such as zinc and other metals, that are necessary for plant growth.
What nutrients are needed for a good fertile soil?
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).
What leads to fertile soil?
Availability of water: moisture retention for continuous water supply. Drainage: most crops can't bear water logging. Aeration: necessary for a healthy root growth and a high activity of soil life. pH (range of acidity): the soil should neither be too acidic nor too alkaline.
What are three components of soil?
Soil contains air, water, and minerals as well as plant and animal matter, both living and dead. These soil components fall into two categories.
Nitrogen (N)
Nitrogen is a key element in plant growth. It is found in all plant cells, in plant proteins and hormones, and in chlorophyll.
Phosphorus (P)
Phosphorus helps transfer energy from sunlight to plants, stimulates early root and plant growth, and hastens maturity.
Potassium (K)
Potassium increases vigour and disease resistance of plants, helps form and move starches, sugars and oils in plants, and can improve fruit quality.
Calcium (Ca)
Calcium is essential for root health, growth of new roots and root hairs, and the development of leaves. It is generally in short supply in the North Coast's acid soils. Lime, gypsum, dolomite and superphosphate (a mixture of calcium phosphate and calcium sulfate) all supply calcium.
Magnesium (Mg)
Magnesium is a key component of chlorophyll, the green colouring material of plants, and is vital for photosynthesis (the conversion of the sun's energy to food for the plant). Deficiencies occur mainly on sandy acid soils in high rainfall areas, especially if used for intensive horticulture or dairying.
Sulfur (S)
Sulfur is a constituent of amino acids in plant proteins and is involved in energy-producing processes in plants. It is responsible for many flavour and odour compounds in plants such as the aroma of onions and cabbage.
What are the three nutrients in fertilizer?
Nitrogen, phosphorus and potassium, or NPK, are the “Big 3” primary nutrients in commercial fertilizers. Each of these fundamental nutrients plays a key role in plant nutrition. Nitrogen is considered to be the most important nutrient, and plants absorb more nitrogen than any other element. Nitrogen is essential to in making sure plants are healthy ...
What are the big 3 nutrients?
The Big 3—nitrogen, phosphorus and potassium —provide the foundational nutrients of today’s commercial fertilizers. Keep following The Voice as we continue to explore fertilizer in-depth in the weeks ahead.
Why is nitrogen important for plants?
Nitrogen is essential to in making sure plants are healthy as they develop and nutritious to eat after they’re harvested. That’s because nitrogen is essential in the formation of protein, and protein makes up much of the tissues of most living things. Below is a picture of corn that is nitrogen deficient. The second of the Big 3, phosphorus, is ...
Why is fertilizer important?
Plants provide food, fiber, housing and a host of other benefits, and fertilizer plays a key role in this process. As the world population is expected to exceed 9 billion by 2050, fertilizer will be needed more than ever to boost crop production to keep people fed and healthy.
How many elements do plants need to grow?
All growing plants need 17 essential elements to grow to their full genetic potential. Of these 17, 14 are absorbed by plants through the soil, while the remaining three come from air and water.
Is corn phosphorus deficient?
Below is a picture of corn that is phosphorus deficient. Potassium is the third key nutrient of commercial fertilizers. It helps strengthen plants’ abilities to resist disease and plays an important role in increasing crop yields and overall quality.
Which nutrient is absorbed by plants?
Potassium rivals nitrogen as the nutrient absorbed in greatest amounts by plants. Like nitrogen, crops take up a relatively large proportion of plant-available potassium each growing season. Plants deficient in potassium are unable to utilize nitrogen and water efficiently and are more susceptible to disease.
What is the potassium needed for a crop?
Potassium (K) is expressed as K 2 O similar to the way to P is referred to as P 2 O 5. Crop need for K varies. Plants use potassium to open and close stomates and to move nitrates from the roots to the leaves. Potassium rivals nitrogen as the nutrient absorbed in greatest amounts by plants. Like nitrogen, crops take up a relatively large proportion of plant-available potassium each growing season. Plants deficient in potassium are unable to utilize nitrogen and water efficiently and are more susceptible to disease. Most available potassium exists as an exchangeable cation (see below). The slow release of potassium from native soil minerals and from fixed forms in clays can replenish some of the potassium lost by crop removal and leaching. This ability, however, is limited and variable. Fertilization is often necessary to maintain optimum yields. See the table at the beginning of each crop section for the potassium needs for each crop.
Why is nitrogen important for soil?
Nitrogen. Nitrogen (N) has a pronounced and often dramatic influence on the growth and yield of crops. Management of soil and fertilizer N is difficult because N undergoes numerous transformations and is easily lost from the soil. These losses concern growers for three principal reasons: 1) N losses can and often do adversely affect plant growth ...
How is N added to soil?
In addition to commercial fertilizer sources, available N may be added to the soil through mineralization (the microbial conversion of organic N to ammonium and then nitrate) of soil organic matter, manure and other organic residuals, and plant litter.
What are the differences between N and manure?
Differences in N content are due to the species of animal, the animal's age and diet, the moisture content of the manure, handling and storage and the amount of bedding in the manure.
Is manure human pathogens?
NOTE: Manure often contains human pathogens. Serious illness has occurred from eating produce where fresh manure was applied without an adequate waiting period (see "Food Safety"). Previous manure applications: Up to 50% of the total N in cow manure is available to crops in the year of application.
Is compost a nutrient?
120 - 150. Compost as a nutrient source: Finished compost is a dilute fertilizer, typically having an analysis of about 1-1-1 (N-P 2 O 5 -K 2 O). The nitrogen content of composts varies according to the source material and how it is composted. In general, nitrogen becomes less available as the compost matures.
