The raw data as reported by groups. Some Background Nitrate, Phosphorus, and Potassium are all nutrients important for plant growth. Atmospheric nitrogen is fixed by bacteria in the roots of cerain plants, so it can be replaced by ecosystems. These nutrients can also be added to crops in the form of fertilizers. Humus is largely decomposed organic material that improves the quality of soil through water retention, for example.
Permeability is the speed at which water travels through the soil.
This is important because good soils drain well and some poor soils get waterlogged because the water can't percolate through the soils as quickly as it should. If water stands for too long then it can kill plants and promote the growth of fungus and mold. The higher the permeability value, the more quickly the water moves through the soil. Capillary water is important because it is a measure of the water-retention qualities of the soil, i.e. how much the soil acts like a sponge. A very high-quality soil will absorb a lot of water, but allow the water that isn't absorbed to pass through quickly, and hence it will have high values for both capillary water and permeability.
