Tillage

to agriculture often cited as having the potential to produce the food, feed, and fiber necessary to sustain us with minimal disturbance to surrounding ecosystems is referred to as conservation agriculture (CA). CA as defined by the Food and Agricultural Organization of the United Nations (FAO), is an approach to farming that “aims to conserve, improve and make more efficient use of natural resources through integrated management of available soil, water, and biological resources combined with external inputs… also referred to as resource effective agriculture” (FAO web site). The central tenet of CA is the combination of year-round soil coverage (cover cropping/mulching) and minimal mechanical disturbance of the soil (no-till/reduced tillage), as well as the use of extensive crop rotations (three crops or greater). Individually these management practices have been shown to provide benefits to soil through enhanced fertility and quality (Snapp et al. 2005; Lal 2004; Reeves 1997), surface and groundwater resources (Hobbs 2007) and climate stabilization through mitigation of greenhouse gas (GHG) emissions (Lal, 2004; Wilcock et al. 2008). However, when these practices are combined as an integrated approach, the synergistic effects have been shown to far exceed the benefits of the practices when implemented on their own (Tilman et al. 2002). The benefits of CA have been shown in a wide range of crop production systems, from low-yielding, dry rain-fed to high-yielding…

Cyrus McCormick, also known as “The Father of Modern Agriculture”, is one of the most influential agricultural leaders in America. His invention, the mechanical reaper, not only changed the way farmers could harvest crops but it also improved their techniques tremendously. Furthermore, farmers did not need as many employees to work on their farm as they did before the mechanical reaper, resulting in the farmer paying less for farm hands and also more crops being produced by the machine faster.…

Tillage is the physical or mechanical agitation of the soil with tools and implements result in good tilth for better germination and subsequent growth of crops. Continuous practice of modifying the state of soil in order to provide favorable conditions for growth of crops is known as tillage addiction. Physical manipulation of soil is intended to destroy weeds, incorporate crop residues and amendments into soil, increase infiltration and reduce evaporation, prepare seedbed and break hard layers…

An essay on plagerism Think back to the first time you ever heard of plagerism. In depth analysis of plagerism can be an enriching experience. While it has been acknowledged that it has an important part to play in the development of man, several of todays most brilliant minds seem incapable of recognising its increasing relevance to understanding future generations. Often it is seen as both a help and a hinderence to the upper echelons of progressive service sector organisations, whom I can say…

There have also been other solutions offered such as precision agriculture, new crop varieties, drip irrigation, and of course better tillage practices. I believe that the best solution out of these is finding better tillage practices. There are many different types of tillage practices such as reduced-till, Conventional-till or intensive-till, and conservation tillage. Conservation tillage as stated by the OECD Glossary of Statistical Terms is a tillage system that creates a suitable soil…

Tillage is an important regulator of SOM decomposition and thus N mineralization. Tillage is used to exploit soil organic nutrient reserves to increase crop yield (Martens 2001). In organic systems, producers often use tillage as weed control. Inclusion of tillage with fallow in crop rotation promotes N leaching (Kessavalou et al., 1998; Sainji et al., 2009). This occurs through leaching, volatilization and denitrification (Sainji et al., 2009). Tillage has a similar impact as fallow on N…

are often applied. However, the replacement strategy is expensive for the farmer and nation and usually poor farmers cannot afford fertilizer. Not only is the fertilizer inputs fossil energy dependent, these chemicals can harm human health and pollute the soil, water and air. Cropping and tillage are another important procedure in food production. Cropping systems decrease runoff and soil loss from continuous cotton to soybean to sorghum to wheat in all tillage systems under climate change,…

Every year, roughly 75 billion tons of fertile topsoil are lost worldwide due to wind and water erosion; and in the United States, we lose about 6.9 billion tons of valuable topsoil each year. If improper soil uses, some farming practices, and the use of tillage tools that leave the soil bare are the main causes of soil erosion; through Agriculture we must look to practices such as no-till farming to reduce soil erosion and preserve topsoil. No-till farming, also called zero tillage or…

1.5, 2km/hr. were 2.06, 2.03 and 1.96 respectively while for Cultivator for same speeds it was 1.48, 1.38 and 1.64 respectively. From the experiment author concluded that power tiller operated Rotavator at forward speed of 1km/hr. was the appropriate method for weeding. J. M. Potekar and D. D. Tekale (2004) [2]: has conducted field experiment to study the comparative performance of tractor drawn implements tillage system for preparation of seed bed. Implements used were Plough, Cultivator, Disc…

The world sees the sun light rise and descend every day out of the year. Most people eat two to three times a day, not knowing where or how that food came to be, where they must relax there bottom side at. They really don’t understand the production of the meals and how they are made to be. They take farmers for granite, not because the disrespect the farmers, the people don’t understand farming as a whole. The many ways consist of; tillage farming, no tillage farming, beef cows, dairy cows,…
