3
Describe the nitrogen
Write a short note on agricultural uses of microorganisms.
Ho do these methods heln to preserve food?​

Answer 1

Answer:

1- A nonmetallic element that makes up about 78 percent of the atmosphere by volume, occurring as a colorless, odorless gas.

2- Microbes include fungi, bacteria and viruses. Farmers and ranchers often think of microbes as pests that are destructive to their crops or animals (as well as themselves), but many microbes are beneficial.

Answer 2

Answer:

Nitrogen is ubiquitous in the environment. It is one of the most important plant nutrients and forms some of the most mobile compounds in the soil-crop system. Nitrogen is continually cycled among plants, soil organisms, soil organic matter, water, and the atmosphere (Figure 6-1). Nitrogen enters the soil from many different sources and leaves the root zone of the soil in many different ways. This flux of nitrogen into, out of, and within the soil takes place through complex biochemical transformations.

Microorganisms can improve crop nutrition and the ability of crops to resist biotic and abiotic stress. Thus, greater utilization of microorganisms in agricultural systems has the potential to allow reductions in the use of inorganic fertilizers, water, herbicides and pesticides.

Among the oldest methods of preservation are drying, refrigeration, and fermentation. Modern methods include canning, pasteurization, freezing, irradiation, and the addition of chemicals.
