Plants which grow and complete their life cycle in habitats with a high salt content are called salt plants or halophytes. Usually that term is reserved only for plants which appear in salty habitats constantly and specifically. Plants occupying only local nonsalty ecological niches in an overall saline environment, or …

Over four-fifths of the surface of our planet is covered with a salt solution (oceans & seas) containing, among many other constituents, approximately 0.5M NaCl. Still, only very few groups of higher plants can withstand such conditions. Most terrestrial species are unable to tolerate even one-tenth of the salt concentration …

পৃথিবীর দক্ষিণ গোলার্ধের দিকে অবস্থিত একটি প্রাচীন হ্রদ খুঁজে পান বিজ্ঞানীরা। পূর্বে এখানে পানি থাকলেও কালের পরিক্রমায় তা এখন ভরাট। তবে তা মানুষ ভরাট করে নি, প্রাকৃতিকভাবেই হয়েছে। এ হ্রদ ভরাট হবার সময় মাটি চাপা পড়ে সেসময়কার গাছের পাতা, কীটপতঙ্গ, মাছ। আর এভাবেই সেখানে তৈরি হয় বিভিন্ন জীবের ফসিল। বিজ্ঞানীরা …

In soil, there may be found 3 types of reactions. They are neutral, alkaline, or acidic reactions. The measure of the chemical reaction of soil(degree of alkalinity or acidity) is expressed by its pH value. Soil pH Soil pH is the negative logarithm of the concentration of hydrogen ion (expressed …

The importance of soil pH can be classified into its direct and indirect effects on edaphology and pedology: Direct Effects 1. Toxic and destructive effect of OH– and H+ ions on root growth It is found that a destructive action on root tissues by acidity or alkalinity usually does not …
