Fruits and vegetables have many nutrients such as vitamins C and A and fiber. They also contain antioxidants called phytochemicals, which help reduce the risk of chronic diseases.
Americans do not consume enough fiber in their diets. Fiber is a diverse substance that comes from or can be synthesized from foods. One of the major differences among fibers is the property of fermentability. For a food substance to be a fiber, it must not be digestible, which means the substance reaches the large intestine.

Testing for soil phosphorus is an important tool to effectively manage phosphorus fertilizer in crop production. It provides an estimate of plant-available phosphorus – both in solution and a readily soluble form in the soil – and fertilizer requirements.
Nitrogen is considered the nutrient that most often limits crop production, yet its optimum management remains a somewhat elusive goal. Sugarcane, a high biomass crop that has high nitrogen requirements, is particularly difficult to manage for efficient nitrogen utilization.
More research effort and time have been devoted to understanding nitrogen dynamics than any plant essential nutrients in the soil. Plants require large amounts of nitrogen to produce amino acids, enzymes, proteins and most important chlorophyll, which harvests sunlight energy for plant use.
Soil is a vital natural resource, making possible the production of food, fiber and fuel. Soil is usually perceived as a reservoir of water and plant-essential nutrients, but soil functions also as a filtering and buffering system for pollutants, keeping the environment safe and healthy for humans and other living organisms.
In drill-seeded, delayed flood rice production, the most important nitrogen fertilizer application is the application applied just before permanent flood establishment. It is important because the largest amount of nitrogen is applied at this time, and it has the largest potential for loss.
Wetlands play a major role in the global carbon cycle because they are an important carbon sink for atmospheric carbon dioxide. Despite their small proportion of land area, wetlands constitute as much as 25 percent of global terrestrial carbon.

Soil testing is critical to resource management. It provides guidelines for the efficient use of lime and fertilizer materials in crop production.
Development of a nitrogen soil test has been a goal of soil scientists for as long as there has been a soil fertility discipline. Many soil test extraction procedures have been evaluated over the years, and attempts have been made to correlate soil test values to a crop’s yield response to applied nitrogen fertilizer.
