This fertilizer has a more long term effect, the fertilizer improves the structure of the soil which makes it easier to hold water and the nutrients it needs to be a long lasting plant(A comparison between). There are not any toxic chemicals that can kill your plant and you can never add too much fertilizer, because there are no toxic buildups. This natural fertilizer is great for our environment, it is renewable and biodegradable, this means we can always have a large supply of the fertilizer. There are also downfalls to go with the natural
Vertical Farming Agriculture has long been with people since the past century and now people need more food than ever before. It is expected that by 2050, the demand for both food and land will increase since many lands and soils that use for growing food will be unusable, and agricultural productivity has its limited (LeBlanc, 2017). As the more population grows, the more arable lands that needed to grow food is losing because the industrial development and urbanization are taking places. If agriculture needs to continue feeding the world, it needs to be more advanced like manufacturing. Fortunately, in these day, experts, entrepreneurs and farmers have been working together to address the upcoming food crisis facing humanity.
However it is sometime considered that the soil health is depends on biological activities held in the soil. There are few controversies about role of soil in plant growth and yield, as few belifs on its direct effect on plant growth and yield, while rest consider that it mere provide physical support and the growth and yield are the result of non-soil components, such as fertilizer and pesticide. Soil organisms contributes significantly in soil health through various ways such as, humus formation, decomposing dead plant and animal residues, enrichment of soil organic matter, etc. They produces carbon dioxide in soil to be dissolved in water and further converted in carbolic acid, which breakdowns insoluble rock minerals (Edwards et al. nd.).
Populations are increasing at a faster than ever. Less land is allocated to farmers, and more land is being allocated for industrial uses or housing. According to USA Today’s Naasz,”Without fertilizer, roughly one-third of the world's population would go hungry.” Climate is irregular and droughts are commonplace. All of these make fertilizer required for any modern farmer. Many misuse it because it is hard to time how much a plant will
One benefit of the use of fertilisers is that nutrients to be at levels necessary to grow crops can take years to build naturally and a single season of crops can completely use and wipe up the naturally produced nutrients. Fertilisers build nutrient levels and allow for crops to be grown more frequently without the worry of whether there is the current amount of soil nutrients. One of major advantage of the use of fertilisers for the environment is that by being able to continuously achieve high yields on the same land for many years, it has limited the need to clear new land for agricultural needs. In some areas where fertilisers are not used, the clearing of land usually occurs after every two or three crop rotations as the land becomes unproductive leaving the old land exposed to erosion. Lastly if fertilisers were not available worldwide agricultural yield would decrease from 85% to 30% causing worldwide crop
INTRODUCTION The increase in population causing higher demand in agricultural commodities for both crop and animal. The increase in population is also associated with the environmental problem currently occurred (Aneja et al., 2006). Due to higher demand in both crop and animal product, farmers throughout the world have sought the problem by increasing productivity. However, due to the fact that the demand need to reach satisfactory, another main problem in animal agricultural industry is unmanaged waste. Waste from animal agricultural industry mainly the manure are very hard to utilised because the amount of manure is too much to handle since the amount of animal itself is quite high.
Particularly in developing countries, a major problem with farming techniques is that they can lead to soil erosion and the degradation of soil quality and fertility from overuse, acidification, salinsation and other chemical contamination. Certain crops, the livelihood of large parts of developing countries – coffee, corn, rice, wheat and tobacco, cause more soil erosion than others. Although these crops are essential to the local community and economy, for farming practices to be sustainable, farmers must be persuaded to modify their practices and apply soil conservation techniques. Which are the (relevant) practices that have an impact on the respective environmental problem? When farmland is ploughed, topsoil is exposed and may be blown away by the wind or washed away by rain.
According to Neary (2006), nitrogen has traditionally been considered one of the most important elements in the soil for the plant nutrient. It is an essential component of the proteins that build cell material and plant tissue. Plants, especially crops need a lot of nitrogen because it is part of many important compounds, including protein and chlorophyll. Nitrogen is changing its chemical form continually and moving from plants through animals, soils water and the atmosphere (Wiederholt and Johnson, 2005). Plants respond to nitrogen in soil in many ways.
Chapter one Chapter 2 Literature review Importance of Nitrogenous fertilizers N fertilizer applications remain essential and are contributing about 30–50 % crop yield increase (Erisman et ,.al. 2008) .According to Smil, (2001) the increased use of N fertilizer has been a major contributor to global food production for the past 50 years .Nitrogen is one of the most important macronutrients needed by crops during their growth cycles.It is an essential component of enzymes, proteins and pigments such as chlorophyll. (Xiaoyuan et ,.al 2003). Nitrogen is known to stimulate crop development, roots and also aids in the uptake of other nutrients. Compared to other major macro elements such as phosphorus and potassium there are no known rock minerals which release nitrogen .Georges, Oswald (2004).
