Vegetable Production

Vegetable Production – Not just planting a few seeds! The production of vegetables is very important in today’s society as we try to promote healthy living. Vegetables provide a major component to achieving a balanced and nutritious diet as they are a prime, convenient and natural source of minerals, vitamins, fibre and energy and are known not only to introduce essential nutrients to the diet but also to help to prevent diseases. Making vegetables available, through production, distribution and marketing, contributes strongly to their consumption and therefore also contributes to a healthier society.There are different approaches into how vegetables can be produced and grown and it depends entirely on the farmer, their approach to farming, and of course the resources available such as; machinery, technology, amenities and the acreage of land available for such a project. There are two general approaches to vegetable production that you must consider if you were to toy with the idea of growing some vegetables whether it be for your own consumption or maybe to supply the nation. These two general approaches are often described as; conventional farming or organic farming.Generally the conventional method involves the use of synthetic pesticides which may or may not be based on naturally occurring compounds to protect crops from diseases, pests and weeds. Crops which are genetically modified to resist or tolerate diseases, pests etc can also be used in this method of farming as a strategy for protecting crops. Crop nutrient management in conventional systems typically involves the application of synthetic fertilizers which can be tailored to meet the needs of specific combinations of vegetables and also include other factors such as soil, climate, water source availability etc.Organic vegetable farming on the other hand relies strongly on cultural & mechanical practises and biological principles for weed, pest, disease and nutrient management. Itâ₠¬â„¢s aim is to produce quality food in a manner beneficial to the environment and to wildlife. In order for a farmer to produce organic vegetables strict regulations and standards must be adhered to before the organic stamp can be used. This includes a restriction on the use of synthetic fertilizers or pesticides for crop management. Crop nutrients, pests and disease can be managed by using a variety of systems such as crop rotation, biological pest control, echanical cultivation or the application of organic amendments to the soil such as manure or compost. Natural pesticides and fertilizers may be used but these are subject to strict standards. Straw or plastic mulch can also be used to help suppress weeds, control pest access to crop, moderate soil temperature and prevent water loss from soil. Organic farmers must be more careful in their plant selection and rely much more heavily on research and information to schedule planting and harvesting practises.This is both in order to sustain the organic approach and also to produce healthier hardier plants through plant breeding as opposed to the genetic engineering methods employed in the conventional method. While both approaches to vegetable production must adhere to national and European regulations in Ireland it is obvious that the organic farmer faces a higher challenge to produce a consistent quantity and quality of vegetables. It seems that if you were to take a stroll down the organic route to production you may need to prepare yourself for some extra work!The approach of conventional or organic farming is essential to determining the other factors which must be considered for vegetable production. After deciding which type of approach you intend to follow to produce vegetables it is then necessary that you consider many other factors. The effect of the natural environment on the production of vegetables can be instrumental in determining the final yield of the farm from year to year. Vegetables can be produced in open fields, semi-enclosed or climate controlled structures or fully enclosed and climate controlled structures.Farms which grow crops in open fields such as potaotoes are limited in their control of such factors and their crops are fully exposed to weather, soil, pests and disease conditions. Fertilization, pest and disease strategies must be employed in order to manage crops and depending on the climate irrigation systems etc may also need to be put in place (not usually a problem in Ireland). Other farmers grow their crops such as tomatoes in semi-enclosed and climate controlled structures such as high tunnels.These high tunnels can extend the vegetable growing season for instance vegetables can be grown when conditions outside the tunnel may not allow this because the high tunnel can limit the exposure of the vegetables to undesirable natural conditions and can sometimes even create conditions more supportive for vegetable growth. For example; placing growing crops w ithin a high tunnel covered by a single layer of plastic shields them from the wind, rain and some pests and can support temperatures higher than that outside the tunnel.Greenhouses are an example of a fully enclosed and climate controlled environment and apart from the enclosed housing and climate control differ from open fields and semi-controlled structures as the vegetables are generally not rooted in naturally occurring soil and are often grown in pots or other containers which provide firm physical boundaries. Of course deciding how you wish to grow your vegetables may be entirely decided by the type of vegetables you wish to grow and depending on the amount and type of land available it may be possible to use only one or maybe all three methods.All of these methods can be used in order to produce certain vegetables all year round where spring and summer conditions may suit the open fields and high tunnel but greenhouses would be needed to produce vegetables in the winter. It evident so that first you must choose your approach to vegetable production, then decide which vegetable or vegetables you wish to produce and then of course decide how you wish to grow your crops whether it be in an open field or in large greenhouses etc.Careful planning and execution in key areas such as site selection, site preparation, planting, management during crop growth and development, harvesting and then distribution to whatever market your produce is destined for is paramount in having a successful and high quality producing vegetable farm. If you are blessed to have a choice of site then the type of soil, the size of the site, the total cost of the site (including tax, land, utilities), access to water, proximity to suppliers, industry etc must all be considered.The site then needs to be prepared for the type of vegetable production you wish to approach. For example in the case of open field; ploughing, dicing or other tillage is needed before planting. If using enclose d or climate structures these need to be assembled efficiently and appropriately according to the type of vegetable or vegetables being produced. Steps are then needed to prepare soil either with fertilizers or green manure and also to minimise weeds, pests and diseases either with pesticides or with the use of cultivation or mulches etc. Planting then needs to take place and depending n the size of the farm this can take place by hand or with machinery generally with each plant spaced a certain distant apart within rows and across rows depending on the type of crop. During the development of the crop a system needs to be put into place to manage the irrigation, fertilisation, weed, pest & disease control and growth of the crop to ensure the crop develops successfully with as little loss or waste as possible. A schedule for harvesting has to be organised and should be followed as closely as possible weather permitting, which unfortunately is not always an allowance in Ireland.Crops can be harvested by machine or by hand and keeping them free of abiotic and biotic contaminants during harvesting is important to ensure quality losses are minimised. Once harvested, it is then necessary to place crops into containers and have them distributed to whichever market they are destined. During all of this hard work it is also necessary to keep records of crop, facility and equipment repair and also to continue your own education as research and new ideas in this industry are always being developed. Evidently if you decide to become a vegetable farmer you don’t just throw a few seeds around in the back field and off you go.Education, preparation and alot of hard work are necessary in order to become successful in this type of farming. You must also consider the marketability of the vegetables you wish to grow and whether they are suited and will develop and grow well in the natural environment supplied to you. Also strict standards are in place for the appearance, shape, dimensions, weight, chemical properties etc of vegetables which can create extra burden and problems for farmers so preparing well and following schedules and procedures will lead to you being a happier more financially secure vegetable producer.Growing vegetables could be a rewarding challenging adventure if you prepare and educate yourself well considering all your options and what is available to you. Then with a bit of elbow grease and hard work you may find that you are producing vegetables which not only benefits society but also may benefit you and increase your bank balance!

A Cheerful Christmas Memory

Recalling this moment, I remember all the soft noise. And together we make screams of colorful clouds of different shades on the children's body and trembling on different flat boxes. In the summer of mid July, the warmth of many letters is comparable to the warmth of the sun. I am very acquainted with these situations. Music is exciting. I think we are a group, but they are very personal. My intense heart knows that this will be another nervous moment again. I love children, but I do not usually feel that it is warm and ambiguous until Christmas, Let's have memories. However, in October every year, mothers support Christmas and are preparing for vacation. I like Christmas bringing out tradition and many love in many ways. When the Christmas tree is near, the world seems not to be such a bad place. Let's decorate your child every year! Then, as they left the house, they had decorations to carry with them. We let the children choose to decorate them rather than to decorate them. In or der to find out when to select, write the year at the bottom. Ideally, I will choose the accessory which is hard to break. Your favorite Christmas memories may be different from us. Everyone may have different Christmas memories. As an example, my wife 's favorite Christmas memories is the first time for us to hang the picture of the youngest child on a tree. My mother-in-law made Christmas decorations with the pictures of our youngest children. When they got big enough to make their own accessories, they started adding their own unique Christmas accessories with their own hands. These are our valuable souvenirs. Over time, these decorations become increasingly special as children grow. Today we have only 1 child left, and she is at home a year and a half before she can attend college.

Thomas Kuhn The Structure of Scientific Revolutions Essay

Thomas Kuhn The Structure of Scientific Revolutions - Essay Example irst stage, â€Å"pre-paradigm science,† details that individuals seeking to comprehend an observed phenomenon do not share universal stock of background theory. In this stage, individuals start from ground zero and endeavor to construct a science from scratch. The lack of a paradigm to organize the data makes all facts to appear as uniformly relevant (Kuhn, 1996). At this stage, individuals lack a tradition that can be passed from one individual to the other for subsequent development and investigation. At some point, some of the inquirers establish an account of the registered phenomenon that bears adequate substance and explanatory power to draw the attention of a host of community of individuals, who will then propel the inquiry along the suggested lines. A paradigm comprises four critical features, which include a body of theory inclusive of laws, background metaphysical assumptions, values and exemplars. The attainment of a paradigm converts pre-paradigm science into normal science. Normal science predominantly comprises puzzle solving whereby the main task details expanding knowledge of facts identified as significant by the paradigm. Investigators, in this case, do not advance bold, fresh theories but employ the accepted theoretical frameworks in fresh and novel sorts of cases. This phase also incorporates enhancing the similarity between the facts and the paradigm’s forecasts, as well as additional development and articulation of the paradigm (Kuhn, 1996). Scientists undertaking normal science do not necessarily work to counter or depose a paradigm, or even seek out to verify whether a paradigm is accurate. The scientists presume that the paradigm is factual, and continue based on that assumption. Working within a paradigm demands that the scientists embrace the core elements of the paradigm as a dogma. The scientist’s main task in this stage encompasses working out the particulars of the paradigm devoid of calling into question the fundamental

From the videos, it was evident that Intel’s development of the first microprocessor (Intel Free Press, 2011); while Microsoft’s software design enabled them to pioneer in this endeavor and assume a proactive stance in related technological developments (Microsoft, 2012). Moreover, Intel and Microsoft capitalized and reaped the following advantages: (1) captured the opportunity to â€Å"exploit network effects and positive feedback loops, locking consumers into its technology† (Hill & Jones, 2012, p. 244); (2) enabled establishment of brand loyalty; (3) generated substantial sales volume which eventually enabled economies of scale and learning effects; (4) enabled offering pricing strategies (switching costs); and (5) gained advanced knowledge on the pioneering experience (Hill & Jones, 2012). 2. From the first and second e-Activities, compare Intel’s and Microsoft’s strategies in terms of their ability to profit from innovation. Next, analyze the manner in which shifts in new technologies revolutionized the structure of the industry, increasing profitability and growth through global expansion. Provide a rationale to support your response. Intel’s strategies, when compared to Microsoft’s strategies in terms of abilities to profit from innovation were virtually on the same field. Through pioneering efforts, both Intel and Microsoft gained substantial market shares within their respective fields of endeavors. As such, the developed core competencies established significant competitive advantage that enabled them to retain leadership in these discoveries. Moreover, the manner in which shifts in new technologies revolutionized the structure of the industry, increasing profitability and growth through global expansion – more commonly known as technological paradigm shifts, affect both Intel and Microsoft. For example, cloud computing, which

The New Employee Orientation - Assignment Example The fright of the newness often make one coil and feel withdrawn, yet at the same time there is the joy of joining a new workforce. Just like embracing what a new day presents, a new employee must seek to embrace the cultural climate in the new work environment before he/she can criticize or become judgmental like in the case presented by Schein (2009). The author presents a case of a CEO (Chief Executive Officer) who became judgmental few days after being posted into a new environment. The surest way of learning a particular corporate culture is by understanding one’s role and how that role fits into the whole organization (Lawson, 2006). Embracing the organization culture involves getting to understand the organization’s mission, objectives, policies and structure (Schein, 2009). The various challenges that come with each new day are like the giants in the â€Å"Giant Tales† which are there not stop one from sojourning ahead but they present a venue for growth and innovation (Cromie, 2008). Notably, the presented opportunities evoke every creative spirit as well as create the good working environment rich with experiences of others to learn from (Baek, 2006). It is worth noting that the success of one in the new environment is basically pegged on the willingness of the new individual to learn and so embrace the new work

Preparing to Teach in the Lifelong Learning Sector Assignment

Preparing to Teach in the Lifelong Learning Sector - Assignment Example and literacy skills among the learners, educators must create a conducive environment that creates conditions for learning (Avis, Fisher & Thompson, 2009). Since learners are of varying backgrounds ranging from cultural to socio-economic backgrounds, educators must provide adequate support to the learners so as to attain the set standards. Additionally, Avis, Fisher & Thompson (2009), say that teaching numeracy and literacy skills is a complex process, and it is the role of the teachers to come up with methods that will suit the multilingual learners. This involves selecting resources and planning instructions so as to meet the high and low order skills in language learning (Avis, Fisher & Thompson, 2009). For teaching literacy and numeracy classes to be productive, educators must develop deep understanding of the main concepts and principles in literacy and numeracy. Avis, Fisher & Thompson (2009), emphasize on synthesizing, explaining, analyzing, evaluating and hypothesizing in the course of teaching multilingual learners. From the lessons I have been keen on, lessons plans presented by the centre, printed materials and articles, motivation of the learners cannot be ignored (Avis, Fisher & Thompson, 2009). In an event whereby the learners are motivated, they tend to engage in the learning tasks. Teachers can motivate the learners by creating a favourable learning environment through modelling, and in turn the learners take risks in engaging in class activities, so as to learn these skills. Since effectual learning of numeracy and literacy skills is based on evidence based research, educational systems must devise literacy and numeracy programs using reliable techniques (Avis, Fisher & Thompson, 2009). Teachers must always assess and evaluate the programs, so as to understand if the learners acquire the information taught in the classroom setting. Lastly, the educators must inculcate a culture of continuity in the learning process if numeracy and literacy

Early civilization Essay Example | Topics and Well Written Essays - 500 words

Early civilization - Essay Example Today, people try hard to adopt the civilized ways some knowingly and others take part in it without the knowledge; largely, this is because of the different cultures and environmental settings that come with the ‘new generation’ where people inherit behavior and traits as part of culture. During civilization, nomadic writing was about how dissimilar aspects interact and change affecting people to become prospectus writers; this involved people using text to communicate about things and situations of their lives. Today, people are involved more in nomadic writing than oral as facilitated by the vast technology advancements; typically, people communicate more through messaging and other facets of the social media. Nonetheless, today’s relations do not necessarily fit the utter definition and characteristics of nomadic writing but the relations and mode of communication adds it all up. During civilization, the male gender dominated the women as they all significant and respected roles in the society; moreover, women felt unmindful and helpless before their suppression to men. The key aspect here was that the men were the head and most substantial in the community. Over the years, there have been changes in the male and female statuses with women making remarkable contributions to the growth of the society by working harder in all aspects and dominating some of the men i.e. education, careers etc. Nonetheless, despite the effort, men are still representing in high-level situations; for instance, the presidency and prime ministers seats in most of the nations have men sitting on them. Reflectively, before development, people used to clothe in a very different way based on the gender; assertively, men used to wear shorts or briefs alone, and women tops and under-garments too (all of the clothes made from animal skin). This mode of clothing was there to ensure that people covered the essential parts of the body, and during

Micro and Macro Economics Assignment Example | Topics and Well Written Essays - 500 words

Micro and Macro Economics - Assignment Example So the jobless workers used to join the companies where there is no existence of the union. As the number of employees increased in those nonunion companies, salary/wages used to get reduce. In this case the spillover effect is [($20-$10)/10]*100= 100%Estimated Union Advantage with the Spill-Over Effect:The revised salary of the nonunion company is $10 where as new salary in the Union based company is $20. Although the spillover growth is showing a value of 100% growth in actual term, growth in the wages in the union based company is 33.33%.Increase at wages in Firm B: The increase in the wages of firm B is known as threat effect. Generally, companies where no union is present used to take this way to minimize the possibility of development of concept of union controlled labour system. Generally, the increase in wages is lesser in this companies compared to that of the unionized firms. As an example, in this example, the rate of increase in the wage for firm A is 50% ($20 to $30) whi ch is unionized whereas for B it is 25%. ($20 to $ 25)Union Advantage: In firm A, the growth in wages are [($30-$20)/$20]*100=50%; whereas for firm b, which is a non-union firm growth in wages are: [($25-$20)/$25]*100= 20%. There is a clear difference of 5% in increase of wages between union and nonunion firm.Prevailing Wage can be defined as hourly wage system, usually added benefit and structured overtime compensation paid to the majority of the people belonging to working group within a particular area.
