LEACHING AND LIMING

leaching and liming in agriculture. advantages of liming. effect of leaching and how to control leaching. leaching is a very critical situation of agricultural production process where water percolation in the soil washes soil nutrients far away from the reach of plants roots

WHAT IS LEACHING?

to avoid speaking big, i want to simplify what is leaching in agriculture. this is washing away of plant nutrient from the top soil further from the reach plant roots

  Leaching is the loss or extraction of certain materials from a carrier into a liquid (usually, but not always a solvent). and may refer to: Leaching (agriculture), the loss of water-soluble plant nutrients from the soil; or applying a small amount of excess irrigation to avoid soil salinity. normal

COMMON REMEDY OF LEACHING IN AGRICULTURAL ACTIVITIES IS THE APPLICATION OF FERTILIZERS.

WHAT IS LIMING

Liming is the addition of wood ash or Calcium compound to the soil in other to reduce soil acidity…. which is condition of too much Hydrogen present in the soil.
The practice of liming is done especially in humid climates where the soils are generally acidic because of too much leaching caused by heavy rainfall

WHAT IS LEACHING?

Leaching is defined as the washing down or downward movement of soil nutrients beyond the reach of the roots of crop plant.

This is usually as a result of too much rainfall.
Leaching is more on sandy soil than any other type of soil. On the savannah parts of west Africa, Leaching is not so much due to low rate of rainfall, however the rate of rainfall is much more greater than the rate of evaporation.
This means that water remains in the soil for a longer period of time thereby causing fast chemical leaching.

where can leaching take place

Leaching in plants can happen in potting containers. Once the chemicals have drained down through the soil, they can leave a crust of soluble salts on the surface, which makes it hard for the soil to absorb water. Removing this crust with water is the other type of leaching.

Word stress is not an optional extra that you can add to the English language if you want. It is part of the language! Fluent English speakers use word stress to communicate rapidly and accurately, even in difficult conditions. If, for example, you do not hear a word clearly, you can still understand the word because of the position of the stress.

Think again about the two words photograph and photographer. Now imagine that you are speaking to somebody by telephone over a very bad line. You cannot hear clearly. In fact, you hear only the first two syllables of one of these words, photo… Which word is it, photograph or photographer?

Of course, with word stress you will know immediately which word it is because in reality you will hear either…

THE NATURE OF WORD STRESS 2

In English we do not say each word with the same force or strength. And this differences in pronouncing words with a different force and strength is what we call word stress

. What is more, word stress in English is quite variable: some words are stressed on their first syllable (e.g.,

 sister, decorate, Arabic

), some are stressed on the second (e.g.,

 present,

arcane, America, attention

), some on the third (e.g.,

decoration, historicity, and referee

), and still others on the fourth (e.g.,

exasperation

Furthermore,  being English a stressed language, one should pay closely attention to the pattern of stress in that language, seeing that word stress is an important pattern in word shape. Besides, a change of this pattern may lead to misunderstanding in communication. Nevertheless, this short piece of writing, strictly speaking, describes the nature of word stress and highlights its importance in mastering English pronunciation fluency

Stress is an important feature of spoken English. Clear, accurate pronunciation of all English words relies on correct articulation and placement of stress.

Additionally, listeners rely on stress as a way to identify words. For instance, if you say “Arabic” instead of the correct “Arabic,” listeners might hear “a rabbit.”

Stress is a quality of vowel sounds. It has three primary characteristics:

Length ↔

Volume 🔊

Pitch ↑

Stressed vowel sounds are longer, louder, and/or higher in pitch than vowel sounds without stress. You can use just one of these features, or any combination of these features at the same time. Overall, stressed sounds are “stronger” than unstressed sounds.
