Soil and crop growth variability in the Sahel (Information Bulletin 49) by J Brouwer and J Bouma 1997 41 pp
In the Sahel, crop growth in farmers' fields varies widely, not only between fields but also between different parts of a single field. These differences are generally related to differences in soil properties over short distances (2-50m). Although such soil and crop growth variability complicates management by farmers, as well as research by agronomists, agricultural scientists have historically ignored it. This bulletin reports on the results of a 5-year project (1990-95) at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) Sahelian Centre (ISC) in Niger, investigating various aspects of soil and crop growth variability in the Sahel.
