“…His favorable valuation of the yields in irrigated gypseous lands appeared in newspapers (De los Ríos, ). The observations of De los Ríos conform to the current local experience about irrigated crops in the Ebro Valley and are consistent with the results of Laya et al () who used an objective method to study the relationship between gypsum content in the soil and irrigated alfalfa yield.…”

Gypseous lands occur mainly in arid regions of the world, where irrigation is required for profitable agriculture. The study of gypseous soils has been neglected for years in the main stream of the soil science. Agriculture and, more recently, the environmental concerns are challenging research in the countries that have extensive gypsum outcrops. Those challenges have been obvious since at least the 1960s, when economic development in some of these countries led to the construction of new irrigation schemes and associated infrastructures. This paper presents examples of documents about agriculture on gypseous soils in Spain that might be applicable to similar situations elsewhere in the world. Copyright © 2016 John Wiley & Sons, Ltd.

“…Gypsum is antagonistic to sodium; the addition of gypsum to the soils improves the structure and hydrologic properties of clayey or sodic soils (Oster and Frenkel, 1980;Hamza and Anderson, 2002). Gypsum can benefi t crops with high calcium requirements in both acidic (Toma et al, 1999) and non-acidic soils (Laya et al, 1998), and reduce phosphorous solubility (Moore and Miller, 1994;Kordlaghari and Rowell, 2006) even though the results are less satisfactory with particulated phosphorous (Cox et al, 2005).…”

The familiarity of mankind with gypsum and its simple composition are in contrast with the frequent mistakes reported for its behavior and role in nature. Gypsum has been studied as a raw material, as a rock constituent, as an indicator of geological and archaeological conditions, and from other points of view. However, its role in Earth surface processes, its relationship to life through calcium in the equilibrium of carbonates and its structural water molecules, seems overlooked. Moreover, errors of gypsum formulation, analysis, and behavior obscure some of its roles within nature. The semi‐solubility of gypsum explains its actions in many soils. The softness, fragility, and crystal water of gypsum are often not considered. Routinely drying at 105°C and pulverizing samples for lab analyses casts suspicion on all analytical results because gypsum becomes anhydrite and/or bassanite at this temperature. Specific physicochemical models are needed to predict the behavior of soils mainly composed of gypsum.

“…Although the use of AEZ-based methods is common, some researchers have criticized the approach (van Diepen, 1993;Laya et al, 1998). One of the main criticisms is that there is a distinct difference between potential and realized productivity (and potential output and actual output).…”
