“…Therefore, the general intent of classifying salt-affected soils is to facilitate discussions of soil management and to group soils according to crop responses (Black, 1968). On the basis of determinations made on soil samples and the influences of the two common kinds of salts (neutrals and alkali salts) on soil properties and plant growth, salt-affected soils have been separated into two broad groups, saline soils and alkali soils (Szaboles, 1974;Abrol and Bhumbla, 1978;Bhumbla and Abrol, 1979).…”

“…In a pot culture study, Pearson and Bernstein (1958) reported 50% wheat yield reduction at an ESp of 43 and with plants containing 17 mg Na g-~ dry matter. However, under field conditions prevailing in Northern India wheat growth is adversely affected only at exchangeable sodium percentages (ESP) higher than 35 (Abrol and Bhumbla, 1979). The soil under investigation had an ESP of 25 and, hence, any damage to the crop due to a specific Na effect is unlikely.…”

In sodic soils of the Indo-Gangetic alluvial plains of Northern India, flooding for short periods often occurs during the growing season of wheat, leading to low yields. A field study was therefore conducted to evaluate the effects of short-term flooding on growth, yield and mineral composition of wheat (Triticum aestivum Linn. emend. Fiori and Paol) in a sodic soil (pH 8.9, exchangeable sodium percentage 25). Flooding wheat for 2, 4 and 6 days at the time of first irrigation (25-day old plants), significantly reduced tillering, plant height, delayed head emergence and resulted in 17.6, 29.0 and 46.7% reduction in grain yield, respectively.

“…Such soils also occur in several other parts of the world (Kovda 1965) and have been characterized by high pH (>8.5), high exchangeable sodium percentage (ESPs>15) and high levels of carbonates and bicarbonates, all of which are detrimental to the physicochemical properties of the soil. Gypsum (CaSO4, 2HaO) has been used as a soil amendment for reclamation of alkali soils throughout the world (Abrol and Bhumbla 1979;Swamp 1981Swamp , 1985Oster 1982). Reclaiming such soils by using cheaper sources of amendments has been a major challenge.…”

We evaluated the effect of agricultural-grade (AG) pyrites (total sulfur 22%) varying in water-soluble sulfur (1-8%) and gypsum on the soil properties and yields of rice and wheat in alkali soils during the years 1993-1995 at the Gudha and Saraswati experimental farms at the Central Soil Salinity Research Institute, Karhal, India. Gypsum and pyrites were applied on the basis of gypsum requirement (GR) of the soils. Results showed that the efficiency of AG pyrites in decreasing soil pH and exchangeable sodium percentage (ESP) and increasing crop yields was dependent on their water-soluble sulfur content at the time of application to the field. Pyrites with 5.5% and 8% soluble sulfur were as effective as gypsum. The freshly mined pyrite (water-soluble S 1%) was found to be inefficient in reclaiming alkali soils. We also explored the possibility of increasing the water-soluble sulfur content of pyrite by optimizing its storage conditions. When pyrite (1% water-soluble S) was stored under moist conditions by sprinkling water over the bags under a rain shelter, there was an enrichment of indigenous iron-and sulfur-oxidizing bacteria of pyrite, and the water-soluble sulfur increased to 5% within a period of 6 months. However no such increase occurred when pyrite was stored dry. We conclude that the soluble sulfur content of pyrite increased during its storage under moist conditions and should be between 6% and 8% at the time of its application to the field.
