calorimetric determination of soil pH



Calorimetric determination of soil pH

In calorimetric methods, the colour developed by the soil colour and a suitable indicator and compared with either by the same indicated in various buffer Solutions or with permanent glass colour standard or with colours on the printed card.
The water extracted must be crystal clear and four methods available to achieve this in filtration centrifugation clearing with a poly electrolyte.

how to remove soil alkalinity from the soil




What is soil alkalinity

Soil alkalinity is caused when there are excessive quantities of soluble minerals in the soil.

The soil which is alkaline is usually found in arid or semi-arid areas like desert and Sahel Savanna.


How to remove alkalinity from the soil

Alkalinity of the soil can be removed through the application of irrigation to dissolve some of the salt present in the soil
The application of some acid fertilizers like ammonium Sulfate can also help to reduce or remove completely soil alkalinity
Important means of removing Alkaline Trio from the soil to the application of sulphur to the soil
This blog post is all about how to remove soil alkalinity it is not too deep but in the case of the pH level of the soil you can read my blog post here on causes of acidity and alkalinity in the soil

causes of soil acidity, effect of soil acidity and how to remove soil acidity from the soil



Causes of soil acidity

The two can be caused by any of the following reasons
Leaching is a major cause of soil acidity. What it means is that through leaching and washing down the nutrients below the soil surface where it is difficult for plant roots to access in order to get nutrients for growth


The use of acid fertilizers. The use of acid fertilizers like ammonium Sulfate and ammonium nitrate can even cause acidity in the soil
The presence of acid parent materials. The presence of acid parent materials can cause the ground or soil to become acidic. The presence of acid parent materials resort in the easy dissolution of The Rock's leaving behind mineral rich in hydrogen ions
Nutrient uptake by plants can cause the land of soil to become acidic. The absorption of soluble minerals from by plant results in the accumulation of hydrogen ions which causes the soil to become acidic
The presence of sulphur in the soil- sulphur undergoes oxidation and dissolution to form weak acid in the soil


Ways to remove soil acidity from the soil

It can be removed by the application of liming materials which are rich in calcium
The following underlisted are examples of learning materials use to remove soil acidity
Limestone
Slake lime
Quick lime
Calcium bicarbonate
Wood ash
Dolomite or calcite
Basic slag
Gypsum
Organic manure can also be applied to remove soil pH or acidity

Effects of soil acidity on crop production
The following are ways whereby the soil becomes acidic and their effects to crops
production low ph or high acidity causes the disintegration of clay materials which are leached from the soil
Low pH causes and accumulation of aluminium and manganese which may be toxic to plants roots
Low pH reduces the population of some useful soil organisms such as bacteria and earthworm
The presence of hydrogen ions may have adverse effect on the roots of plants as it hinders the absorption of mineral ions
Soil acidity causes nutrient deficiency especially calcium phosphorus and nitrogen
Soil acidity reduces the activities of soil microorganisms
Humans can easily be leached out of the soil if the pH is high
Soil acidity Reduces the formation of pods in legumes
Soil acidity causes reduced growth and yield of crops
The effect of soil acidity causes lower rate of decomposition of organic matter due to its adverse effect on soil microbes

what is SOIL PH and the the pH scale



what is SOIL PH and the importance of soil pH to agriculture

What is SOIL PH and its agricultural importance to crop production

The meaning of soil pH
The world ph (pondus de Hydronium) the hydronium is defined as a measure of the degree of acidity or alkalinity of the soil. Soil pH can also be known as a measure of the concentration of hydrogen ions present in the soil

A higher hydrogen ion concentration indicates soil acidity while a lower concentration of hydrogen present in the soil indicates oil alkalinity

What do we mean by the pH scale?
A typical pH scale is graduated from 1 to 14 and has been developed to measure the degree of acidity or alkalinity of the soil.
Soil pH below 7 is said to be acidic and above 7 in the pH scale is alkaline while 7 itself is neutral.


Image of PH pondus de Hydronium scale here

From the above image of pH scale that we just suck up there we can deduce that
pH 2 is strongly acidic
pH 6 is slightly acidic
pH 7 is neutral
pH 8 is strongly alkaline
pH 13 is slightly alkaline

what is soil temperature and its agricultural importance to crop production



what is soil temperature and importance of soil temperature

What is soil temperature and how temperature affect agricultural production
The nation of soil temperature

Soil temperature can be defined as the temperature within the soil
In other words what temperature can also be known as the temperature at is different from the atmospheric temperature which is above the soil so sorry temperature is usually the temperature degree that is affected or that is felt within the soil or in the soil

General importance of soil temperature to crop growth and production in agricultural science
Underlisted are some of the importance of soil temperature to crop
Soil temperature determines the rate of formation and decomposition of soil organic matter
Low temperature causes a decrease in metabolic activity and reduction in enzymatic reactions in plants
Extreme temperatures will impede the activities of microorganisms present in the soil
Temperature affect the level of soil moisture thereby decreasing the productivity of the soil
The rate of temperature affecting the soil will also affect its capacity to absorb water and nutrients by root crops
Optimum temperatures promote seed germination
Appropriate temperatures also promotes the sustainable development fruits
Temperature is most often determines the population of soil microbes
Temperature often determine the maturity and ripening of fruits
Optimum temperatures promote the activities of soil microorganisms like
A higher temperature will always cause wilting of fruits and leaves
High temperature leads to loss of soil nutrients through volatilization
High temperature may be harmful to crops by causing premature dropping of fruits

what is SOIL STRUCTURE and types of soil structure




What is soil structure and types of soil structure

Definition of soil structure
Soil structure is defined as a structure referring to the ways in which the different particles of the soil are packed or arranged in order

Soil structure also refers to the shape and arrangement of primary particles to form compound particles

Structure has a direct effect on crop yield and production. If they soil structure is good, I will circulate and waterlogging will reduce dramatically including erosion.
so the structure of the soil can be preserved in the following ways
So soil structure can be preserved through planting of cover crops in the Farm
The use of mulching materials is very key in the preservation of soil structure
We can also apply manure green manual liming to preserve soil structure
In order to avoid spoiling the soil structure of a given land we should avoid overgrazing the area
Avoidance of clean clearing with machines is necessary to avoid exposing the soil to erosion
I want to list all types of soil structure has to be found in agricultural science

TYPES OF SOIL STRUCTURE

Here is a list of the types of soil structure that can be obtained anywhere in the world
Single grain soil structure. In this type of soil structure their primary particles exist in single form and are not cemented together it is found in sandy soil
Crumb Structure- this type of soil structure exist in large gravels of tones embedded within the primary particles which are cemented together it is found in the topsoil
Plate like soil structure- this primary soil structure known as plate like structure is the primary site particles that are arranged in horizontal and flat method resembling plate or reflex on top of each other it is commonly found in the subsoil
Spheroidal structure- spheroidal soil structure is also referred to as granola structure the particles are cemented together in a circular form with lots of spaces it is commonly found in topsoil
The prismatic soil structure- this type of soil structure could be columnar or prismatic. This type of structure of the Soul is just like steroidal structure which have a spaces when the top ones are around there are columnar when they are flat just like a prism if they are prismatic it is found in subsoil
Like soil structure- the aggregate are like blocks whose edges are irregular and maybe either be sharp or round. It is commonly found in the subsoil

General importance of soil structure
The following are if you list of the general importance of soil structure to agricultural production
Solid structure helps to determine the level of fertility of the soil
Another very importance of soil structure is that it also prevents soil erosion and water logging
A good soil structure will promote the activities of soil microorganisms
A dependable soil structure that is good for farming activities will always support the growth of crops to a maximum degree
Every good soil structure will always have the capacity to retain water and moisture for plant growth
