Techniques like precision agriculture are now a very hot area for researchers. It is a technique where they utilize information technology to manage and plan crops. It is often categorized as agricultural management systems which employ advanced sensor technology and data from geo sensing satellites and crop history database to help farmers take better decisions. They are also used as monitoring tools to analyze crop and land data. Precision agriculture techniques also help farmers make better decision by providing them with forecasts on crop prediction, fertility, rainfall and market demand.
By putting appropriate chemical to the land, it helped to create higher yields to counterbalance the loss of available agricultural land. Furthermore, application of pesticides helped agriculture to
Optical remote sensing (RS) is used to provide an effective knowledge base for advanced agriculture research (Ambast et al., 2002). Visible - Near Infrared (NIR) wavelengths offers the ability to monitor landscape process that are controlled by several surface parameters (Jacob et al., 2002; Price, 1992). Most commonly a simple or normalized ratio between the visible red and the NIR spectral wavebands are used for vegetation indices (VI). Several vegetation indices have been developed using the linearity of the NIR versus red reflectance as an indication of the green biomass. Some of the more sophisticated indices attempt to neutralize the soil influence by using a parameter or curve for bare soils.
Integration of crop and livestock enterprises help farmers manage risk. The more enterprises that a farm has the more resilient it is to unforeseen risks. Th... ... middle of paper ... ...ostives. Farmers integrate crop and livestock enterprises for several reasons. Economics is one reason, and this is mainly to stabilize farm income and make it less variable from year to year.
To grow the best crops, farmers must start with the best soil. Agronomists show farmers how to maintain quality soil. A soil high in quality will contain a topsoil with plenty of residues. These residues reduce the amount of runoff. Now that we know how agronomy benefits the farmers and the environment, let’s learn about the income and different job opportunities with
Evolution in the complexity of agricultural methods and techniques has occurred in part due to a search for maximum efficiency by an advancing society. Efficiency has always been a dominant motivational factor for new techniques to be allocated in this field, and in this last century, especially in the last decade, changes unfathomable to farmers past and present have taken place along the lines of efficiency. Along with increased use of fertilizers, high-yielding hybrid seed varieties that have been produced by plant breeding techniques have dramatically increased the average production per land area. In recent years, the scientific community has developed a process enabling genetic engineers to insert genes expressing a desired trait into crops that had not been able to obtain these genes from other species through cross fertilization methods. These genes can then be passed down to the seeds of the newly recombined plant and will be expressed in the generations following.
In addition, the usage of artificial pesticides and chemical can cause human having health problem and soil with poor structure and aeration and also the nutrient availability will decreasing. Hence, more and more pests and disease become difficult to control as they become resistant to artificial pesticides (HDRA – the organic organistion, 1998). Azadi and Ho (2010) highlighted that the productivity in different fields includes agriculture can be improved by developing their technological strategies. Living modified organisms (LMO) or known as genetically modified (GM) is one new technical method that can be used to develop new crop varieties through genetic engineering technique which will provide potential contributions to sustainable agricultural productivity and also new inputs for resource-poor and small scale farmers. According to Kruff (2001), GM seeds defined as seeds that have been modified to contain specific characteristics such as he... ... middle of paper ... ...M. (2012).
Being an agricultural engineer, you have to apply knowledge of engineering technology and biological science to agriculture (“Agricultural Engineers careers” para.1). You are able to discuss plans with the clients, contractors, and consultants (“Agricultural Engineers” What’s para.3). At the job you will prepare reports, working drawing, specification proposals, and have to make budgets for proposed sites or system (“Agricultural Engineers” What’s para.3). If you work as one often you must be able to address problems that may occur or come up in a short period of time (“Agricultural Engineers” U.S. para. 15).
11) It provides manure while it returns fresh organic material to the soil. This increases soil biological activities and soil health and function improves, cover crops improve soil quantity and nitrogen and reduce weed. 111). Cash crops can also benefit the physical and biological soil characteristics and soil structure potential reduce erosion. iv).
Conclusion To fulfill the growing needs of world's rapidly expanding population in a sustainable manner, crop growers must employed different approaches. Technologies such as precision agriculture are a new frontier in management strategy, technology and practices to enhance decision making. Tools such as remote sensing will play a major role in precision agriculture technology where useful data can be obtained quickly to help increase productivity and ultimately, profits. Additionally, innovative scientific methodologies enable and accelerate development of seed varieties with desired traits such as high yield and good drought tolerance. Both approaches when used efficiently and correctly will enhance decision making, reduce costs and risks, increase productivity and profitability to achieve sustainable agriculture.
