Crop rotation British Agricultural Revolution. The rotation between arable and ley is sometimes called ley farming. George Washington Carver (1860s–1943) studied crop-rotation methods in the United States, teaching southern farmers to rotate soil-depleting crops like cotton with soil-enriching crops like peanuts and peas. In the Green Revolution of the mid-20th century the traditional practice of crop rotation gave way in some parts of the world to the practice of supplementing the chemical inputs to the soil through topdressing with fertilizers, adding (for example) ammonium nitrate or urea and restoring soil pH with lime. Such practices aimed to increase yields, to prepare soil
Crop tolerance to seawater slightly sensitive. There is no crop classified as tolerant, not even moderately tolerant. In the Texel report, also the Van Genuchten-Gupta model (giving an S-curve) was used to find the soil salinity at the 90% yield point. The rationale for this was not given. The Mediterranean Agronomic Institute, Valenzano, Bari, Italy South coast grew 5 cultivars of lentil irrigated with sea water of different salinity levels. Saline water was prepared by mixing fresh water (EC = 0.9 dS/m) with sea water (EC = 48 dS/m) to achieve salinity levels of 3.0, 6.0, 9.0 and 12.0 dS/m. Some of the results
