Can we increase available nutrients using bacteria?

The intensive land use, including the artificial N-fertilizers in agriculture causes the acidification of soils due to the harvest or leaching of cations. Soil microbes are of great importance in cycling nutrients such as carbon, nitrogen, phosphorus and sulphur. Beside their effects on the availability of nutrients the bacterial soil life prevents the uptake of several harmful ions. The most important limiting factor for microbial growth in soil is the abundance of available organic carbon sources. To increase microbial activity in a soil one must make the environment optimal, or at least more favourable, in terms of aeration, moisture and pH, and above all provide the organic substrates needed to fuel the population
