Right now more than six billion people live on the earth, and numbers are rising very quickly. By 2050, earth will carry seven billion people, and every one needs to eat. Human beings eat plants or animals that have been raised on plants, and agriculture is the science, art, and business of growing food.
Humus contains organic material - living tissue that has died and its components are being recycled. Microbes like bacteria and fungi work on organic material, breaking it down into its smaller building blocks that can then be taken back up by a new plant. Humus has a structure that makes it easy for living plants to find and take up the nutrients. Some of the salts, for example, stick on the ends of long wavy molecules that are easy for plants to grab. Humus is dynamic and always changing. The community of microbes can be very diverse and stable as long as more and more organic matter is fed to the soil to maintain all those microscopic creatures (Donahue et al. , 1983).
Plants also need lots of water for proper growth. Water will just run through sand or ground rock so humus along with the clay holds water in the soil.where it will be available to plant roots. Soil provides the matrix where seeds are first nurtured. When the seed first starts to grow, it pushes out tiny roots to begin interacting with the soil to find water and nutrients. A green, leafy stem pushes up out of the soil reaching for the sky because plants receive energy from the sun to make them grow. The water at the top of that stem evaporates into the air and pulls more water and nutrients up from the soil into the plant. ...
Unfortunately, when they eat from the plants on a farm, they are eating our food, so any farming system must consider these pests. Conventional and organic farmers take different approaches to these two main issues: maintaining enough nutrients to feed the plants and protecting plants from pests.
Conventional agriculture emphasizes maximizing yield and farming efficiency. These farmers look at the growing population and say that we need all the food we can possibly grow. Such farms use chemical fertilizers to replace the nutrients that plants take up out of the soil. These are generally, mineral salts of nitrates, phosphates, and potassium. These are applied to the field as dried pellets that dissolve in water. By putting these nutrients into the soil, the conventional farmer is certain that his plants will have enough for the fastest and maximum growth. Such plants often take up lots of water with the nutrients which swells them and makes them look fat and juicy and easier to sell Of course, every time it rains or the farmers irrigates the field, some nutrients will travel with the water wherever it go - sometimes into nearby rivers and streams, so often nutrients are lost when applying fertilizers. Such outside nutrients can sometimes disrupt the delicate ecosystem balances in the waters where they end up.
Conventional farmers also act strongly when pests like insects or weeds interfere with growth of their crops. These farmers spray specially made poisons on or around plants to kill off the pests. Many farmers also spray 'prophylactically' before pests arrive so plants will not have any losses or even markings from insect pests. Unfortunately, these poisons are not specific to one certain kind of insect. ...

Organic farming is a young growing industry. In general terms, it is built around the idea of producing food that green, clean, and healthy. In other words, the production process is designed to use sustainable products, and no part of the process uses any form of artificial chemicals to enhance its products.
With the progress that the organic food industry is making it is becoming clear that many people are realizing how important what they put into their body really is. This industry is changing the tide of the national food enterprise, farming, and the whole of agriculture period.
According to the Codex Alimentarius (Le Guillou & Scharp, 28), organic farming involves holistic production management systems (for crops and livestock) emphasizing the use of management practices in preference to the use of on-farm inputs. This is accomplished by using, if and when possible, cultural, biological and mechanical methods in preference to synthetic materials.
On the individual level, people have generated a preference for foods based on health, social, and political considerations. Organic foods, once a novelty, have gained an increasing market share as the public has begun to realize the potential health benefits of consuming foods that are pesticide and herbicide free.
This research shows that what is now occurring is just the beginning for the organic food industry. In the next few years the popularity will become something that is more main frame in society rather than right now being a new fad among the people. Along with culture and socialization, media is another of the factors influencing food habits.
This is something that they will never be short of, if the right policies and reforms are introduced within this sector. There are many questions which need to be answered with the help of these reforms. Although agriculture seems to

Conservation agriculture involves a process of soil management practice that minimizes the distractions of the soil structure, natural biodiversity and composition. The study that is described in the paper is based on 1700 farmers in Paraguay.
Traditionally manufactured food items require methods of agriculture that lead to erosion of the soil and it takes several years for the soil to recover from the damage. In case of organic foods require lower amount of pesticides which keeps the health of the
