The answer to the absence of fast-acting nitrogen fertilisers, with arable crops and grassland, has been threefold first, to make much greater use of farmyard manure, and to make sure that it is properly stored and not allowed either to be washed down the drains or to volatilise into the air second, to make much greater use of the legume for its power of nitrogen fixation, particularly white and red clover...

Agriculture comprises arable land and grasslands with 10% and 15% of the land area respectively the percentage contribution to the land biomass production corresponds to 11% to each part (ca. 4.2 Gt/y C-equivalent). The main products are human and animal food. In the course of the next SO to 100 years, food production has to increase in proportion to the population from 4.2 Gt/y C for 6 billion today to about 7 Gt/y C for an almost 10 billion population. This aim can be achieved by a combination of (1) an increase of the arable land area and (2) a productivity increase with the help of fertilisers etc..
