WATER SAVING TECHNOLOGIES IN AGRICULTURE-A SURVEY ABSTRACT Nowadays, Water is an essential part of our life. Hence water is considered to be basic need of human. In recent years, water consumption increases due to globalisation and population growth. There is a challenge in day to day life of every country to sustain the fresh food requirement and reducing the farm water consumption. Agriculture is the main occupation of human being.
With increasing demand for food and competing use within the water sector, the pressure is on irrigation professionals to manage water efficiently. One of the measures that have been considered in the last years is the introduction of some level of automation in the canal operation. This means the presence of control systems able to automatically operate canal cross structures based
It is often considered to be a science dealing with eco-regions as it depends largely on climate and properties of soil in a particular area. These factors vary largely from one place to another. Many individuals are of the opinion that agricultural science depends on the local weather and local soil characteristics, so specific crops need to be studied locally. History The path breaking work of Gregor Mendel in the field of agriculture made its study very popular around the world. However, in the
Design and fabrication of fertilizer splashing machine Page 10 CHAPTER:- 2 LITTERATURE REVIEW Agriculture will remain the major source of incomes for most countries of the third world. Consequently, scientists must develop new creative models for agricultural machinery. To have better understanding of the centrifugal distribution machines of solid chemical fertilizers, the recent review of literature will be drawn as indicated
Flooding events can be mitigated through dykes or mobile flood protection systems. Emergency systems for droughts must be tested and prepared. Operating personnel must be trained in advanced for these tasks. Only then are the adjustments to climate change successful and the required emergency measures correctly targeted.Eventually, water scarcity is among the main problems facing many societies and the world nowadays. Water use has been growing at more than twice the rate of the
On one hand there is the problem of water scarcity and on the other, the streets are often flooded during the monsoons. This has led to serious problems with quality and quantity of both surface and groundwater. In order to conserve and meet the daily demand of water requirement, it’s time to think for alternative cost effective and relatively easier technological methods so that water can be conserved. One of the best methods fulfilling those requirements is Rain water harvesting. It is used to collect runoff or flood water for storage in the soil profile or in tanks so that it can be used for the production of crops, trees or fodder.
Agricultural activity has always been an important economic driver in Guyana, most significantly along the low coastal plain, along the coastline bordering the ocean and in between large rivers and waterways. It can be said then, that agricultural activity is very closely intertwined with the water environment. Pesticides, weedicides and fertilizers have been used in all agricultural activity primarily for better yields and profits, but this has also had negative effects of contributing to pollution of the water ways. This occurs through a combination of leaking, surface run off and disposal directly into the waterways (Abdullah and Bacchus). Mining over the decade grew larger and larger in size and scale, it is now one of the most important economic driving force in the economy of Guyana.
According to Hall (2008), micronutrients are essential elements for plant in very small quantity. Although it is found in enough quantity in the soil, it can be depleted over time if not replaced. It can cause soil to become acidic or alkaline and toxic if it is too much presents in the soil. Micronutrient is required in the correct amount for healthy plant growth. On the other hand, soil organic matter contains a significant proportion of the available fraction of micronutrients and is very important in the nutrition of crops.
Irrigation: Irrigation is usually as manual or artificial application of water to soil for the aim of activity wetness essential for plant growth. Irrigation water will come back from close streams or beneath well water (groundwater) or storage ponds specifically designed to gather high river flows throughout winter. Pipes, channels and wells into the bottom enable water to be taken from its supply to the farms, vineyards and orchards wherever it 'll be used. These days a various vary of ever-evolving technologies exist to with efficiency apply irrigation water to crops. What quantity water is employed depends on the kind of crop, the soil during which the crop is being big and also the quantity of precipitation in this space.
