Synchrotron-based X-ray absorption spectroscopy (XAS), specifically X-ray absorption near edge structure (XANES) spectroscopy, indicated the dominant species of As in soil and sediment samples was arsenate [As(V)], which is similar to the chemical form of As in the groundwaters of this region. No evidence of arsenite [As(III)] was identified in any of the solid-phase samples, including earthworm castings.

Soil microflora and their diversity study are now modern trends to know the proper soil health. Greater diversity of fungi in soil indicates better health of soil. In this experiment agricultural soil, barren land and garden soil were taken for their micromycoflora study and the diversity of microfungi were analysed by Simpson index and compared among the three types of soil. Total 563 colonies were isolated from the 38 soil samples collected from three different ecosystem types. Sixty eight (68) different species belonging to 31 genera were recorded.

Conventional tillage practices may adversely affect long-term soil productivity due to erosion and loss of organic matter in soils. Sustainable soil management can be practiced through conservation tillage (including no-tillage), high crop residue return, and crop rotation.

Soil health refers to the biological, chemical, and physical features of soil that are essential to long-term, sustainable agricultural productivity with minimal environmental impact. Thus, soil health provides an overall picture of soil functionality. Although it cannot be measured directly, soil health can be inferred by measuring specific soil properties (e.g. organic matter content) and by observing soil status (e.g. fertility).

: High concentrations of petroleum hydrocarbon (PHC) pollution can be hazardous to human health and leave soils incapable of supporting agricultural crops. A cheap solution, which can help restore biodiversity and bring land back to productivity, is cultivation of high biomass yielding willow trees.

Soil is crucial to life on earth. Enormous agriculture practices may emerge a numerous problem like reduction in soil fertility, erosion, ground water contamination which has direct impact on the soil health. It is indispensable to study overall microbial activity potential and different changes in soil biological properties for maintaining soil health and its quality. Soil enzyme is essential to play important role in maintaining soil health and to asses it quality.

Soil health indicators such as soil physico-chemical properties, total bacterial count, microbial enzyme activities were monitored at different crop growth stages (such as before ploughing, after transplantation (0 DAT), max tillering (45 DAT), flowering (60 DAT) and maturity (90 DAT) of rice variety Pusa Basmati 1. The treatment comprises green manure Sesbania rostrata and inorganic fertilizers for organic and conventional respectively. Moreover, field was cultivated with rice variety Pusa Basmati I.

Soil organic matter content and several fractions of soil organic carbon are considered to be sensitive indicator of soil health who on several conditions like cropping choice and management practices. The presence of different soil organic C pool in rice cultivating soils are well documented but thoroughly studied information on relation between soil C status and different rice based cropping managements are not available.

Macro-fungi are the fungal species that produce fruiting bodies visible to naked eyes and occurs widely in the rainy season. The macro-fungi plays important role in nutrient dynamics, soil health, as pollution indicator, species mutualism and its interaction and even has its economic role in carbon cycling and the mobilization of nitrogen and phosphorous. Present investigation emphasizes on study of macro-fungi from Baramati area of Pune district of Maharashtra. During the study frequent field visits, listing of genera and their species, identification and photography has done.

The climate determines selection of right crop and its sequence for a particular location, while the prevailing weather conditions dictate the potentiality of that crop and nitrogen use. On an average every 1oC rise in temperature could lead to a 20 per cent reduction in crop yields. Therefore, the two big challenges viz., finite cultivable land and rise in temperature have to be overcome by agricultural sector to sustain crop yields. In this direction, one of the ways is to use weather and climate as non-monetary input in crop production. Among the crops, rice is a weather sensitive crop.

A field experiment was conducted at the Experimental Farm, Department of Horticulture, Assam Agricultural University, Jorhat during November 2016 to march 2017 to study the “Performance of Chilli (Capsicum annuum) cv. „Krishna Jolokia‟ as influenced by organic inputs and microbial consortium”. The results indicated that application of RDF (T1) recorded the highest plant height (82.38 cm), fruits plant-1 (98.56), fruit length (7.99 cm), fruit girth (1.01 cm), fruit weight (2.09 g), fruit yield plant-1 (268.33 g), fruit yield per hectare (13.07 t) with the B:C ratio of 4.60.

There is a persistent environmental concern that transgenic Bt-crops have indirect undesirable effect to natural and agroecosystem function. We investigated the effect of Btcotton (with Cry 1 Ac gene) on soil biology in Bt cotton growing soils of Perambalur district, Tamil Nadu under rainfed scenario.

Continuous applications of organic manures and inorganic fertilizers have been reported to affect soil pH, electrical conductivity, Soil organic carbon, available N, P and K. Electrical conductivity has been used as chemical indicator of soil biological quality in response to crop management practices. Continuous application of organic manure and inorganic fertilizer decreased soil pH but increased total soluble salt concentration.

This implies some degree of subjectivity as to individual perceptions of what can be deemed “good quality” (Blanco and Lal, 2008). More recently, the discussion has been centered on the concept of „soil health‟, largely defined for soil biological properties (Doran and Jones, 1996). Both concepts are focused on assessing soil functions in the landscape, but there is no explicit reference state to be used in a soil quality or health framework. Soil quality indicators are normally chosen according to the research focus.

Hence, part of farming community shifting from chemical inputs to bio-inputs. In this regard, this study was conducted to know the extent of awareness, usage pattern, product differentiation, factors affecting and purchase pattern of bio-pesticides in Chitradurga and Davanagere districts in Karnataka state. The data pertaining to this study was collected with the help of pre-tested questionnaire during the agricultural year 2018.

Agricultural intensification is placing tremendous pressure on the soil’s capacity to maintain its functions leading to large-scale ecosystem degradation and loss of productivity in the long term. Therefore, there is an urgent need to find early indicators of soil health degradation in response to agricultural management. Our purpose was to review the literature in which a wide perspective of soil quality and the complex task of its assessment, considering the inherent and dynamic factors, are introduced.

Use of biocontrol agent to increase the growth of crop has been an alternative source to meet the demand of growing population. Plant growth promoting rhizobacteria (PGPR) are the soil bacteria inhabiting around/on the root surface and are directly or indirectly involved in promoting plant growth and development via production and secretion of various regulatory chemicals in the locality of rhizosphere. These bacteria competitively colonize the roots of plants and can act as biofertilizers and/or antagonist (biopesticides) or simultaneously both.
