top soil due to leaky roots and the death of and nutrients cycling from roots and soots. Deep rooted plants will tend to reduce the amount of nutrients that otherwise might be lost through leaching egg: chicory which has the potential to rescue leached nitrogen and also by virtue of having freshly roots at deep profile take up phosphorus from those depths.
High root biomass plants are more beneficial for soil microbial activates and especially for earthworms. Plants like grasses, cereals and lupines should be included in a rotational plan to maximize benefits from good soils, biological activity and earthworms. Some deep rooting plants like chicory and dandelion improves the ability for burrowing earthworms to access greater depths and improving soil structure and drainage in the subsoil area.
After humans commenced cropping in fixed locations, it was soon seen that a soil sickness developed if the same crop was grown year after year. When several types of crops were alternated between seasons in the same area overall yield were improved and this has been described as a positive rotation effect. Soil sickness and rotational effects are interrelated the soils sickness being caused by lack of rotation and rotation effects representing the avoidance of soil sickness by using a different crop. In the university farm, rotation programmed by rotating different types of crops in a fixed area of land has maximized potential of microorganisms in the soil. A crop with a high phosphorus requirement may reduce available phosphorus levels and this could be followed with a crop for which yields are not phosphorus limited. This is possible because different crops require a different spectrum of nutrients.
In conclusion, rotations are one of the fundamentals keys to successful and sustainable agricultural cropping. Suitable crops and organisms in particular are usually based around sound rotation principles giving biodiversity. Over time and space reducing pests, weeds and diseases issues and improving soil fertility. Wherever possible catch crops, green manure and under sowing techniques should be used to keep the soil covered as much as possible protecting it from erosion risks and reducing nutrient leaching particularly in winter.
