Soil Nutrients and Plant Fertilization Midterm II

In a single year, uncovered manure loses [blank_start]3[blank_end] % of solid mass: [blank_start]10[blank_end] % of the total Nitrogen content, 3% of the total [blank_start]Phosphorus[blank_end], and 20% of the total [blank_start]Potash[blank_end] content.

For each of the following materials, determine if it is a "brown" or a "green" nitrogen contributor. Manure [blank_start]Green[blank_end] Wood chips [blank_start]Brown[blank_end] High Nitrogen material [blank_start]Green[blank_end] Low Nitrogen material [blank_start]Brown[blank_end]

As a soil nutrient, potassium behaves similarly to [blank_start]Phosphorus[blank_end] , because it is found predominantly in [blank_start]Mineral[blank_end] form and is more subject to [blank_start]Biological[blank_end] weathering processes.

The transformation from sulfites to sulfates is classified as [blank_start][biological][blank_end] weathering, and is an example of an [blank_start][oxidation][blank_end] process.
