Nitrogen furnishes a major component of chlorophyll where it’s known for its ability to grow green leaves. Potassium provides a measure of disease resistance to plants and protection from the cold.

Intertidal wetlands though are resilient to this stress through adaptations and as well as induced human strain through modern knowledge and conservation programs. Mangroves normally grow in the inter-tidal areas‚ with loose‚ soft sedimentary soil along the coast. The soil has an unstable substratum‚ a rather high salinity level and lacks breathability for oxygen intake. Living in such an adverse condition‚ mangroves have their unique ways to adapt and grow. In order to become resilient towards natural

Keywords: Vibro methods‚ Deep Soil Mixing‚ Grouting techniques‚ applications in infrastructure projects ABSTRACT: Ground improvement techniques utilising Vibro methods‚ Deep Soil Mixing and Grouting technologies are finding increasing application in Malaysia to solve a broad spectrum of geotechnical problems. This paper will describe recent applications in Malaysia for four separate projects – Jet Grouting to form stable cutter-head interventions for a tunnel project; Deep Soil Mixing to support deep

moisture can occur when water seeps through foundation cracks. What are some of the causes of foundation cracks? Some common causes include poorly compacted soil‚ soil erosion‚ hydrostatice pressure‚ and plumbing issues. When the weather fluctuates between periods of wet and dry weather‚ the soil will shrink and expand. This will cause the soil to move and shift under the foundation‚ creating voids‚ or holes‚ beneath it. Eventually‚ the foundation will start to sink and settle into these voids‚ leading

Deforestation: Deforestation causes frequent floods. Every year about 30 million people and 10 million hectares are affected and the property lost may run into thousands of corers of rupees. The annual loss of top soil is estimated 6000 million tonnes; its value in terms of money is enormous. Soil erosion also causes siltation of lakes and rivers. Felling of trees and destruction of forests cause imbalance in forests ecosystem. That reflects in the loss of varieties of flora and fauna. Forest loss is

Chemical Fertilizer vs Organic Fertilizer A chemical fertilizer is defined as any inorganic material of wholly or partially synthetic origin that is added to the soil to sustain plant growth. Organic fertilizers are substances that are derived from the remains or by products of organisms which contain the essential nutrients for plant growth.

DEFORESTATION Deforestation has been described as the cutting down of trees without planting others in their place. Deforestation‚ clearance or clearing is the removal of a forest or stand of trees where the land is thereafter converted to a non-forest use. Examples of deforestation include conversion of forestland to farms‚ ranches‚ or urban use. It is hard to think that there was a time when 90% of the earth was covered by trees‚ but this was once the case. More than half of the animal and plant
