What are biofertilizers and mention the significance

Why does salinity create problems for plants and how do they adapt?

Which criteria helps determine which fertilizer to use.Group of answer choices a. Does it contain the needed nutrients? b. Does it readily release those nutrients? c. Expense d. Side effects e) All of the above

The practice of crop rotation uses nitrogen fixation to create fertile fields. First, a plant without a nitrogen-fixing relationship, such as corn, is planted. After the harvest, a nitrogen-fixing plant replaces the initial crop. Instead of harvesting the nitrogen-fixing plant, however, it is plowed under. The cycle continues in this manner. Crop rotation would allow the farmer to reduce which of the following?    a) Planting seeds. b) Watering the fields. c) The use of manufactured fertilizer. d) The burning of fossil fuels by farm equipment.

What are the consequences of soil erosion in urban settings?

Plants obtain ______ by taking it up from the air. a. nitrogen c. phosphorus b. carbon d. water

What is bioenergy from the biomass, especially, agricultural wastes?

The practice of crop rotation uses nitrogen fixation to create fertile fields. First, a plant without a nitrogen-fixing relationship, such as corn, is planted. After the harvest, a nitrogen-fixing plant replaces the initial crop. Instead of harvesting the nitrogen-fixing plant, however, it is plowed under. The cycle continues in this manner. Why would nitrogen-fixing plants be plowed under instead of harvested?    a) To increases usable nitrogen in the soil. b) To increase water retention. c) Nitrogen-fixing plants are not a food crop. d) To decrease bacteria in the soil.
