In a rice-based cropping system soils are often subjected to different moisture regimes, which may influence desorption of adsorbed Zn and thus limit Zn availability to crops. Laboratory and greenhouse experiments were conducted to study the effect o

The role of blue-green algae (BGA) and Azolla in supplying N to rice fields is well documented. In addition, they also bring about, directly or indirectly, a number of changes in the physical, chemical and biological properties of the soil and soil-w

Fixation of Zn and Cu applied to tropical rice-growing lateritic soils rich in Fe-oxides may be reduced if the soils are kept flooded for a few days before their application. There may be a further reduction if such flooding is combined with incorpor

We investigated boron (B) adsorption characteristics for 16 acid alluvial soils as a function of equilibrium B concentration (0–80 μg/mL) and the effect of soil properties on such adsorption. The adsorption data for the soils could be described by

The effect of growth and subsequent decomposition of cyanobacteria (inoculated and indigenous) on changes in P fractions was studied in four soils under submerged condition. The growth of cyanobacteria in soils caused an increase in organic P with co

Lateritic soils usually contain high amounts of oxides of iron, which are known to have strong zinc-binding capacity. When such soils are used for growing flooded rice and zinc is used as fertilizer, much of it is likely to be fixed by oxides of iron

N2-fixing blue-green algae (Cyanobacteria), besides enriching soils with N and organic carbon, may modify a number of chemical and electro-chemical properties of the soils resulting in a change in availability of some micronutrient elements. Keeping

SUMMARYNo-tillage and dry ploughing were compared with puddling under identical cultivation conditions for their effect on growth and yield of wet-season rice. The experiment was conducted on an alluvial sandy clay–loam soil over 5 years (1978–82

We have studied in the laboratory the effect of different levels of P application on the transformation on native as well as of applied zinc in a rice-growing soil under two moisture regimes viz., flooded and nonflooded. Application of P caused a dec

We investigated in the laboratory the distribution of applied Zn at two levels (5 and 10 ppm) in two soils (Alfisol and Ultisol) under two different moisture regimes, viz., continuously submerged and alternately submerged, with two levels of organic
