His later book, The One-Straw Revolution, was published in 1975 and translated into English in 1978. From 1979, Fukuoka travelled the world extensively, giving lectures, working directly to plant seeds and re-vegetate areas, and receiving a number of awards in various countries in recognition of his work and achievements.
During the fallow period, shifting cultivators use the successive vegetation species widely for timber for fencing and construction, firewood, thatching, ropes, clothing, tools, carrying devices and medicines. It is common for fruit and nut trees to be planted in fallow fields to the extent that parts of some fallows are in fact orchards.
Fallow syndrome is when a crop has insufficient nutrient uptake due to the lack of arbuscular mycorhizae (AM fungi) in the soil following a fallow period. Crops such as corn that are prone to fallow syndrome should not follow a period of fallow, but instead should follow a cover crop which is a host for AM fungi, such as oats or other small grain crops.
Crop rotations also affect the timing and length of when a field is subject to fallow. [37] This is very important because depending on a particular region's climate, a field could be the most vulnerable to erosion when it is under fallow. Efficient fallow management is an essential part of reducing erosion in a crop rotation system.
Exact dates are hard to determine, as people collected and ate seeds before domesticating them, and plant characteristics may have changed during this period without human selection. An example is the semi-tough rachis and larger seeds of cereals from just after the Younger Dryas (about 9500 BC) in the early Holocene in the Levant region of the ...

Fields which are fallow may be tilled or sprayed to control weeds and conserve moisture in the soil. The 1997 Census of Agriculture reported that 20,900,000 acres (85,000 km 2 ), almost 5% of the 431 million acres (1,740,000 km 2 ) of all cropland, was fallow that year.
Pioneer species tend to be fast-growing, shade-intolerant, and tend to reproduce large numbers of offspring quickly. The seeds of pioneer species can sometimes remain viable for years or decades in the soil seed bank and often are triggered to sprout by disturbance. [19] Mycorrhizal fungi have a powerful influence on the growth of pioneer ...
