Relationship between soil and nutrition in plants
Answers
Answer:Soil is a dynamic three-dimensional substance that covers some of the world’s land surface. It varies from place to place, in response to the five factors that form it: climate, topography, organisms, the parent rock below surface, and time. Our Maine soils developed since the last glacier moved across the region, largely in response to the parent rock (largely granite) and topography. Most Maine soils are acidic, and have a somewhat depressed ability to hold and exchange nutrients used by plants. Our native plants evolved in this system, and are well adapted to Maine soils. However, we often amend Maine soils by adding organic matter, lime and/or fertilizer, in order to increase the productivity of our food and landscape plants.
Soil performs four major functions:
It provides habitat for fungi, bacteria, insects, burrowing mammals and other organisms;
It recycles raw materials and filters water;
It provides the foundation for engineering projects such as buildings, roads and bridges; and
It is a medium for plant growth. This text focuses on this last function.
