“…However, the intrinsic qualities of acid soils are thought to impair agricultural productivity by 30 to 40% [8]. The most fundamental causes of soil acidification include leaching due to excessive rainfall, acidic parent material, organic matter breakdown and the release of organic acids, the harvest of high-yielding crops, and the presence of alumina-silicate minerals [9,10]. In tropical and subtropical areas, acid soils are common and possess the key characteristics of low pH, highly soluble excessive Al 3+ , Mn 2+ concentrations, and reduced cation exchange capacity (CEC) that restrict plant development in acidic soils [11].…”

Acid soil is a hindrance to agricultural productivity and a threat to food and environmental security. Research was carried out to assess the impact of lime and organic manure (OM) amendments on yield and nutrient uptake by using the T. Aman-Maize-Fallow cropping pattern in acid soils. The experiment was set up in an RCBD design and used nine treatments and three replications. The treatments, comprising of various doses of lime, OM (cow dung and poultry manure), and a lime-OM combination, were applied to the first crop, T. Aman (Binadhan 7), and in the next crop, maize (BARI Hybrid Maize-9), the residual impacts of the treatments were assessed. Results demonstrate that the highest grain yield, 4.84 t ha−1 (13.61% increase over control) was recorded for T. Aman and 8.38 t ha−1 (58.71% increase over control) for maize, was achieved when dololime was applied in combination with poultry manure. The total rice equivalent yield increase over the control ranged from 20.5% to 66.1%. The application of lime with cow dung or poultry manure considerably enhanced N, P, K, and S content and uptake in both crops, compared to the control. Thus, it may be inferred that using dololime in association with poultry manure can increase crop productivity in acid soils.

“…Approximately, 84 per cent of the soils in the North Eastern Hill (NEH) region of India are acidic having low available phosphorus (P) and zinc (Zn) and toxicity of iron and aluminum (Lyngdoh and Sanjay-Swami, 2018). To overcome the problem of soil acidity, farmers adopt variety of soil amendments like ash, manures, lime, compost and bio-sorbents.…”

This article is based on a study aimed to determine physiochemical parameters, fecal coliform, total coliforms, heterotrophic plate count, arsenic, iron and lead of water to evaluate their effects on human health. Analysis was carried out on tube-well water collected from Nalitabari township of Sherpur District in Bangladesh. The dissolved oxygen (DO), total dissolved solids (TDS), salinity and electrical conductivity were in the ranges of 4.30 to 7.30 ppm, 350 to 792 mg/l, 0.2 to 0.5%, and 715 to 1,970 μS/cm. The pH values were slightly lesser or more than permissible value. Due to the vicinity to the latrines, 17 tube-wells’ water was contaminated by fecal coliforms. The highest heterotrophic plate count was 7.5×103 cfu/ml in ward-8 of the town. Eschericia coli and Vibrio cholerae were identified in ratio of 30.56% and 18.06%, respectively, in the tube-well water, resulting into diarrhea among children. About 6.94% of tube-well water was contaminated with arsenic. 3.25% and 4.5% respondents were suffering from skin diseases and headache, respectively. So, an alternative source of drinking water should be arranged for a better public health of present and next generations.

Indian traditional farming system prior to the 20 th century was generally organic in nature with low production potential. The chemo-centric technological advancement during green revolution period boosted the production potential and provided food security to the nation. However, over a period of time, this production system has started exhibiting its carrying capacity as reflected by production plateau in green revolution belt like Punjab, Haryana, Western UP, etc. The success of industrial agriculture and the green revolution in recent decades has often masked significant externalities, affecting natural resources and human health as well as agriculture itself. Further, increasing consciousness about conservation of environment as well as health hazards associated with agrochemicals and consumers' preference to safe and hazard-free food shifted interest in alternate forms of agriculture in the world. The major challenge in organic farming is the availability of huge quantity of organic inputs. Use of animal excreta based manure is not sufficient for meeting the nutrients demand of crops. The present paper deals with the various options/resources available for effective nutrient management or soil health management under organic production system.
