Climate change and vigorous impact on Sri Lankan Agriculture

Image
  Literally, climate change is the long-term shift in temperature and weather patterns. These shifts are natural and due to the variation of the solar cycle. Nevertheless, human activities have been the main driver of climate change. Without any doubt, weather and climate are the most important factors of agricultural productivity in any country. According to statistics, the average temperature of the country is increasing annually at a rate of 0.01-0.0360C. farmers are not able to face climate change since the high growing population, poor ways of trade, weak infrastructure, lacking knowledge of new technology, etc.  Sri Lanka doesn’t get regular rainfall according to the monsoons. Maha season and Yala season are the main two cultivation season of Sri Lanka that is fed by the Northeast Monsoon and southwest monsoon respectively. Whereas dry zone and intermediate zones are the major food-producing zones. Droughts and floods are experienced frequently due to changes in rainfall...

What is Biosystems technology

Image
                                   Basically, biology means studying life. This word derives from the Greek word where “bios” is life and “ logos” is study. system is a collection of parts that work together to complete a specific task. Hence you know that biosystem is not a simple thing. Yeah, it is a complex topic where we can talk and learn many aspects. Once you separate the parts of the car into the engine, tyers, body we can say each part as a car but once these parts are integrated, it is a car, and it functions as a car. This is very similar to a system and biosystem also functions like this. Another example is a living cell. Life is marvelous. Animals, plants and fungus are the living things that are visible. Bacteria, virus and other microorganisms are living things that are not visible to our naked eye. There are a few characteristics that are displayed by living things (life). By these....

Develop a Hydroponic system

Image
  Introduction 1.0 Hydroponics is a technique of growing plants in nutrient solutions with or without the use of an inert medium such as gravel, vermiculite, rockwool, peat moss, saw dust, coir dust, coconut fibre, etc. to provide mechanical support. Hydroponic means a Greek word that hydro means water and ponos means labor and water work.  Professor William Gerocke coined the first hydroponic in 1930. At Purudue University developed Nutri culture in 1940 and between 1960 and 1970 commercial hydroponic systems were developed in Arizona, Abu dhabi, Belgium.  Due to urbanization and industrialization, conventional farming methods were not enough and made a wide negative impact. To feed the increasing population sustainably modifications on growth mediums were tried out. Agriculture without soil includes hydro agriculture (Hydroponics), aqua agriculture (Aquaponics) and aerobic agriculture (Aeroponics) as well as substrate culture. Among this hydroponics, techniques is gaini...

Soil Moisture sensor

Image
  Introduction 1.0 What is soil moisture sensor 1.1 Soil moisture is a critical parameter in Agriculture. If there is a shortage or overabundance of soil moisture will impact plants badly. Hence determining soil moisture content is significant. Soil moisture is basically the quantity of water available in the soil. Efficient water management and irrigation will lead to improving the quality and quantity of the harvest, conserving water and energy, and reducing nutrient leaching. One of the easiest and most effective ways of irrigation is introducing sensors to agriculture. There are many ways of determining soil moisture content in the laboratory. Even so, without laboratory practices, soil moisture can be determined automatically, effectively, and quickly by using a soil moisture sensor.  This soil moisture sensor (Fg.1) is commonly used in smart gardens and smart agriculture to determine the soil moisture content in the soil. It measures the volumetric water content in soil ...
